Under Rydon Hill

Welcome to this blog about my time away from the tedium of domestic management. Once called "Tits and Things", now sub-titled "Life in Quantoxia", there's plenty of bird ringing (90%), some odd bits of general birding, some local steam trains, some personal bits and occasional 'away days' in other parts of Britain. Rydon Hill overlooks the lower valley of the Doniford Stream, where most of these activities take place.

So far, so good

We are now into spring proper and heading for the breeding season of our summer migrants. Our resident birds are well and truly into their breeding season and I have already ringed a fledged (1J) Robin on the 12th.

This report deals with April to date. The garden is a picture, full of flowering primroses and polyanthus and other spring flowers. On the non-avian front, the slow-worms are basking under the tin sheets, the majority of the frog spawn hatched, giving us several hundred tadpoles, (signifying a stock of mince in the freezer), and the toads re-appeared. Bumble bees and other insects made hay with the Ribes blossom, Peacock and Small Tortoishell butterflies were on the wing and the plum trees blosomed and the Camellia flowers wilted. As yet, we await the Bluebells and the main apple and pear blossom season ... and the Redstarts.

All attention has had to be devoted to the garden as I am suffering with prepatella bursitis, or 'house-maids knee' for those of a non-medical persuasion. The local resident birds are mopping up the bird food as quick as I can put it out, both on the tables (3), in the feeders (6) and on the kitchen lawn. To this end, I have had to expend £180 to replenish stocks of SFH, suet pellets, finch seed and mealworms, totalling 65 kg. I will  pick up the millet when I go to Bedford on Sunday. Thank goodness the Wood Mice seem to have buzzed off for the summer.

The three pairs of Herring Gulls are assiduously guarding their nest sites from others and the Jackdaws. A few base sticks and fleshy bits have been put down but none are anywhere near complete. The Lesser Black-back pair have now returned; I don't as yet know where they intend to set up home. This should be their 'parenthood' year if things go to plan.

First Willow Warbler of 2015
(a whiter shade of pale)
Chiffchaff - with pollen horn
The first Swallow, a male with long streamers, appeared on the 6th, the same afternoon that an Osprey flew resolutely north. Yesterday, there were at least 3 Swallows and the first House Martin wheeling overhead. Three new species have been ringed this month - namely, Great Spotted Woodpecker, Rook and, of course, Willow Warbler. The first 'Willy' arrived on the 8th and sang "out front", and I caught a different male the following day. None of the males has been carrying much fat (0-1), whereas the more recently arrived females have all been heavy for their smaller size and fat 2-3.

The first fledgling to be ringed was a Robin that I found in the net on the evening of the 12th.
Fledgling Robin (1J) 12-04-15
All together, I ringed a further 74 birds of 19 species, plus handled 52 individual retraps. So far in 2015, I have ringed just 350 new birds, of which 127 are Goldfinches (36.3% of birds ringed this year to date). There have been 229 handlings of them all told, consisting of 200 'new for year' individual Goldfinches. Some of these have been new or returning migrant birds that drop in for a day or two to feed up before pushing off further north. Our local breeding birds are much leaner and don't just use the feeders but inspect all the plants in the garden and even try to get in the fruit cage. They also appreciate the fine, groomed hair from my Belgian Shepherd.

With just one 60' net, the list of new birds ringed, with other birds ringed previously in brackets, is:
Gt. Spot Woodpecker - 1
Rook - 1
Goldcrest - 1 (2)
Blue Tit - 2 (1)
Great Tit - 1 (2)
Long-tailed Tit - 1 (2)
Chiffchaff - 5; the only female on the 13th
Willow Warbler - 10; males first, females from the 12th
Blackcap - 6 (1); lingering male on 6th, new birds from the 9th
Wren - 3 (1)
Starling - 2; no unringed birds seen - 6 pairs known
Blackbird - 1 (4); all now feeding young in the nest
Robin - 3 (5);
Dunnock - (4); not as showy as last month
House Sparrow - 2 (6); a few are nesting, others are still thinking about it
Pied Wagtail - 1; minimum of 3 pairs present, poss 4 pairs.
Chaffinch - 4 (2) + 1 adult male (2x) with severe FPV
Greenfinch - 4 (11); 9 males + 6 females, 6 aged 5 (2CY)
Goldfinch - 26 (12); 8 of the retraps were 2CY, only 2 of the new birds were adults (3CY+)
       Finches still dominate in the catches, but Collared Dove (up to 7), Jackdaw (5), Starling, Blackbird, Robin, Dunnock and Pied Wagtail are most likely to be seen feeding in the garden at any time of day.

No fools in sight

The gales are subsiding now; fortunately we escaped without damage this year. Last spring, we lost part of the roof and a very old Rowan that took the fence with it.

The garden is full of bird activity. There are also quite a few Wood Mice around, munching into the bird food on the bird table. We have to translocate these to a neighbouring small-holding some 4-500 metres away. The butterflies are starting to wake up, too. When we took the old potting shed down, we discovered a fat, female Slow-worm under a discarded piece of corrugated iron sheeting amongst the Bluebells.

The Robins are busy collecting either nest material, lining or worms almost non-stop. They also nip onto the bird tables for the old sultana or suet pellet. At least one has a wrinkled brood patch, indicative of sitting on eggs in one of the hedges. We have at least three pairs of Blackbirds, also foraging in the garden. The females are less frequent now and are more likely to visit alone, a sign that they are probably sitting, too. The Pied Wagtails can all be distinguised by the direction that they head for when they are either fed or disturbed by a bigger bird. Obviously nesting on/in different buildings. "Peg Leg", who has a 'club foot', is still with us; I first ringed him in July 2012 as a 6M. 

The Starlings roll in every morning in their twos. I've ringed ten so far this year but not re-trapped any from previous years (which amounts to a mere seven in three years). When we came here we hardly ever saw a Starling in the village, except during winter. I noticed two more unringed ones this morning - trap set!

Adult male Greenfinch (spring)

Chiffchaff with pollen horn













Over the last two or three weeks, the main movement into the feeders and the tall Ash trees beyond the bottom hedge has been of Chaffinch and Greenfinch. Some of this is of returning birds as there seems to be much displaying and singing around the tree tops. They do drop down sometimes, low enough to connect with the orchard net. (see below).

The Goldfinches have been inspecting the herbaceous border and the vegetable garden for nesting material including my Belgian's fine hair, which I put out for them after she's had a brushing. Again, there seem to be three pairs attempting to nest close by, with several more that shoot off from the feeders in the direction of the hedges by the railway or at the rear of the 'industrial estate'/ local tip - sorry, I mean the recycling centre.

The veteran male over-wintering Blackcap was seen singing this morning and also when he came to the bird table. I wonder when he will push off for his 'unknown-to-us' homeland and traditional nesting territory. The incoming migrants should be with us within the week, fingers crossed.

The meadows are ready for some attention but the poor weather prevents us from attending. I did hear the Dipper this morning and a lone Chiffchaff but the bushes/trees are barely breaking bud at present, providing no cover. A Wheatear passed through on the 13th, the day after a small Redwing passage. As long as it doesn't rain hard for any length of time, we will make our first visit of the year after Easter.

This period, I managed to find 20 species, covering 38 new birds and 45 re-captured individuals, in the net(s). The weather has been a problem from a safety point of view and there's not much on the migration front yet either, except some Chiffs.

Woodpigeon - (1); heavyweight at 619 gm
Collared Dove - 1; a fledging that got taken by a Sparr. 2 days later
Jackdaw - 1; adult female with brood patch (B2) on 23rd
Goldcrest - 1 (1); a pair, caught on subsequent days (together)
Blue Tit - 1 (4); they are an "unknown quantity" and not common hereabouts
Great Tit - 1 (2); 2 known pairs
Chiffchaff - 4; all males, the first 2 on 16th/18th were full adults, the other two on 18th & 30th of uncertain age - but the latter most likely 2CY 
Blackcap - (1); the over-wintering 5 female, showing fat3
Wren - 1 (1); both adult males
Starling - 5; two adult pairs & a 2CY male
Blackbird - 4 (3); 4 new adults; on the move?
Redwing - 1; another adult; definite shortage of 1st year birds here
Robin - 1 (7); omni-present!
Dunnock - 1 (2); there are more than this here at the moment!
House Sparrow - 3 (7); all males bar a lone female
Pied Wagtail - (2); and regular, old pair
Chaffinch - 4; all 'age5' females
Greenfinch - 3 (3); males with a single female
Goldfinch - 5 (10); 
Siskin - 1 (1); both males, possibly nesting locally (no fat)

One recovery received -  a 5M Siskin to Callandar (Stirlingshire), a distance of 567 km in 87 days (spring 2014), controlled by a ringer (= probably nesting)

That's it. More news in a couple of weeks or so, Deo volente.

Lovebirds and Fisticuffs

Here we are again and things have moved on somewhat from my last post. 

Our Robins are now paired up, with the males watching their mates as they feed up or collect nesting material around the garden. The males are looking very cocky. I think we have three pairs but I have only been able to re-trap the ones around the back during the last three weeks; the pair at the front have a different routine.

Our Blackbirds, too are well advanced with the females showing a well defined brood patch. They come separately in their pairs to the meal-worms and suet pellets on the lawn but occasionally they arrive at the same time. This is when the males have a 'set to' and fight like Moorhens, with their feet in the air, clawing at each other. There are four pairings that we can identify by ages and plumage, plus some "stray" virgin (2CY) females that may be 'on passage'.

The main tally of new birds consisted almost entirely of finches. I did spook an adult Redwing from the ivy berries in the side hedge yesterday which ended up in the net.  It will be a couple of weeks yet before the main exodus of our winter visitors will take place. It normally occurs about the same time as the influx of Chiffchaffs and the first Willow Warblers arrive.
How the Redwing gets its name

The Blackcaps are winding themselves up for the up-coming breeding season - the males are getting quite tuneful. I also caught a new male with "fat 4", which is where the fat deposits bulge and reach the end of the clavicles (the bird's collar-bone) and there is a clearly bulging pad of fat on the abdomen. This build up will enable a night flight to the near continent, assuming that it will make towards the direction of Hungary or some other spot in central Europe. I expect our wintering population to leave us in the next week.
First winter (continental) female Blackcap
There are still plenty of Goldfinches attending the SFH feeders. One male, that was hatched locally and who has been through one breeding season, showed a well defined cloacal protuberance, a sign that he is already thinking of another family. It will be a further three weeks before his mate will begin to lay eggs, but a nest site and constructing a nest will be his current priority - and keeping his mate well fed! 


 
 Some Goldfinch tails to ponder over
Although we get Rooks in the garden throughout the year, it is only now, when they are nesting, that they (a few regulars) actively seek out the bird food, especially any suet/fat based products and the meal-worms tossed onto the kitchen lawn. Late May into June sees the best time to catch and ring any in the garden; I don't have any traps large enough for one so rely on netting them then. We also get Jackdaws, one of which is "pied"

Jackdaws thieving the suet pellets
I've started to open up the net rides down the meadows in anticipation of being able to ring some north-bound migrants. Right now it's out of the question, since it's cold and wet outside and the stream is 'brown' and in full spate. I'll have to hurry up if I want to catch some Meadow Pipits should the weather change to "favourable"! 

Here are the 59 new birds that have been trapped over the last three weeks, together with the number of different individuals re-trapped.
Collared Dove - 1
Blue Tit - 1; just seen 2 pass the window unringed!
Coal Tit - 1
Long-tailed Tit - (1)
Blackcap - 2 (1)
Blackbird - 2 (4)
Redwing - 1
Robin - (4)
Dunnock - 2 (1)
House Sparrow - (1)
Chaffinch - 16; 13 females, only 4 adults
Greenfinch - 12 (1); 9 females, just 2 adult females
Goldfinch - 19 (18); 24 of these were males (14=2CY), 2 unsexed
Siskin - 2 (1)

Well, that's filled up a cold and rainy day. 'til next time, "take care".

We're on the move

Things have been a little slow of late, hence the long interval between posts, but there seems to be some movement just recently. Over the past three weeks, my new bird totals have been 17, 17 and 34 - and the weekly species total has risen to twelve.

First year male Goldfinch completing PJ moult (October)
Naturally, at this time of year, Goldfinches have returned to Number 1 spot, with 18 new birds and 9 retraps last week, despite the periods of wind and rain that hamper much of our ringing hereabouts.  I am well over 500 new for the year already - with the main influx of newbies still to come (hopefully) - plus 72 individuals from last year, 14 from 2012 and 7 from the year before, my first here.

First year male Blackcap (October)
Same bird - underside (note the pale yellow flush)
The other tell-tale sign of winter is the catching of Blackcaps; the first (a 1CY male) on the 18th was right on cue, then another (1CY female) on the 22nd and three more since. I checked on the number of birds that were ringed in the orchard last winter (November - mid-March); it came to 22 birds, with two of those returning from previous winters.

Fun shot of a male Goldcrest's crown feathers
Another sign of the impending short days was the presence of a few new Goldcrests. The species breeds quite locally to us and I retrap birds from March to June, but after that it's only the odd new bird until the clocks go back when we then expect some winter arrivals, most likely passage birds heading for the Exmoor forests to the south-east of us. 

The bird that is missing so far - is Redwing. I saw one locally on the 14th and then a flock of 18 on the 25th. There was a major arrival on the north-east coast of England overnight on 28/29th so it will be another week or so before we see them regularly and, hopefully, one or two in the net.

Perversely, we saw a Swallow hurriedly heading south over the house on the 22nd in the late afternoon! Our local birds left ages ago.

The composite list for the last three weeks is: 
[same period retraps omitted]
Gt. Spotted Woodpecker 1 - adult male
Goldcrest 3
Blue Tit 1 (5)
Great Tit 1 (1)
Long-tailed Tit 4 (6)
Chiffchaff 1 - hatch year female
Blackcap 5
Wren 3 (3) - all young birds
Blackbird 2 (3) - just the 1 adult (female), retrapped
Robin (3)
Dunnock 2 (5)
House Sparrow 5 (6)
Chaffinch 1
Greenfinch 1
Goldfinch 38 (18)
118 birds of which 68 were new birds

Immature male Great Tit. Note the large, shiny bib.

One piece of late news - the southern end of the meadows has been fenced off, the horses now confined to the northern section. This means we can put nets up again, not just while the hay crop is growing.

About to burst into action?

It's that time of year again, when summer turns to autumn and the days get appreciably shorter and cooler. It is also the time of year for a complete change of the local avifauna; the summer visitors have left, the winter visitors are soon to arrive and different, resident species take advantage of the feeding stations, although the individual birds may now be strangers to the area also.

From a bird-ringing point of view, it is our quiet time. The remaining regulars know the score and how to get to the food without getting caught too often. Hence the shuffling of the feeders and the net. But still it's quite quiet and slow going. It was the time to get on and sort out the garden for the winter - all those chores a big garden demands.

The last 28 days' figures (145 handlings of 127 birds) attest to the change in the seasons: daily figures - new, (recaptured), species;
Week 38 - 0 (0) 0; 8 (8) 3; 4 (13) 3; 1 (2) 2; 1 (2) 3; 1 (1) 2; 5 (4) 5;
Week 39 - 1 (1) 2; 0 (0) 0; 3 (1) 2; 0 (3) 2; 2 (3) 1; 2 (4) 4; 4 (2) 4;
Week 40 - 0 (1) 1; 3 (0) 3; 2 (0) 2; 0 (2) 2; 0 (2) 2; 3 (3) 6; 3 (3) 6;
Week 41 - 3 (0) 2; 4 (4) 3; 3 (2) 1; 3 (3) 4; 9 (2) 8; 2 (6) 2; 10 (0) 3;

It can be seen that the last week has produced nearly half of the new birds for the period. The change in the weather probably had something to do with it, as well as the moult season coming to a close. The picture is not as bleak as it appears when you know the minimum number of individual birds that have availed themselves of your hospitality. 
If we then total them up, leaving out any birds that were caught more than once, we get 76 new birds of 17 species, plus 51 recaptured birds from an earlier period, as follows:

Collared Dove 1
Goldcrest 2 - in the last two weeks; one was an adult female on tail shape
Blue Tit 2 (4)
Great Tit 2 (2)
Coal Tit 1 - adult male
Long-tailed Tit (1) 
Chiffchaff 2 (1) - all in the first week, the r/t was from the meadow a month earlier
Blackcap 1 - in the second week
Wren 8 (2) - two surges of young birds
Blackbird 5 (1) - half of these were on the last day, so movement has started 
Robin 6 (3) - all new birds (juvs) in the second/third week
Dunnock 0 (4)
House Sparrow 14 (16) - 30 birds but at least double that must have used the bird table
Grey Wagtail 1 - this female has taken a shine to our little pond 

Female Grey Wagtail
Chaffinch 4 - all this year's young
Greenfinch 1 (1) - a declining species, it seems
Goldfinch 26 (16) - making a strong presence in the last week (18 new, 8 r/t)

Goldfinches make up over a quarter of all the birds I catch and this year looks like being a bumper one for numbers. I have caught just six birds so far this summer (1%) that were ringed in 2011 (my first year here), four of which were at least 3 years old and one male was at least 5 years old. I will probably add to that in the coming weeks.

Meanwhile, in and over the garden we have had a couple of Magpies, four Jackdaws, up to nine Collared Doves, just the dominant pair of Herring Gulls, a Buzzard, a Raven and the daily parade of Rooks. This week, the Dipper has started singing again down at the stream and the Little Egrets pop by about once a week.

So, it looks like the winter feeding and ringing season is almost upon us and the bird food bill is about to spiral upwards. At least I don't have to think of the cost of rings like some teams, who can ring 3-400 new birds in a session, and on several days a week. I should just be able to achieve that sort of number between now and the end of the year!

I hope it won't be as long as this has been before I have something new to report

A sign of spring

What a difference a week makes. The warmth of last week has brought on the flowering shrubs and the primroses and a few bluebells. Consequently, the bumblebees made an appearance; Peacock and Small Tortoiseshell butties were also on the wing. And then ... FOG. After a glorious weekend (too glorious for catching), on Monday and Tuesday we had heavy overcast and the following three days have seen dense FOG which has not cleared because of our proximity to the Bristol Channel. We are feeling cold and damp right now, whilst much of the country has had lovely sunshine. We're promised better things tomorrow, though - that'll mean wind!

Primroses (early March)
On Sunday morning (9th), I was walking my dog along the coast at Watchet and had stopped to chat to a local woman. I was facing the sea, or I might have missed it, when I noticed a  male SWALLOW coming in-off; it turns out that it was the first for the county this year. There were 30+ Turnstones and some Oystercatchers but no Dunlin or Purple Sands that I could find (1 reported) on the rocks at high tide.

The 1st Chiffchaff of 2014
(note the short primary projection)
On Thursday, I found the first Chiffchaff in the net late morning. Another one came today. Neither had prominent "pollen horns" or were carrying anything other than the barest amount of fat reserves. I wonder where they had come from; the far south-west or France perhaps, or even really local, surviving in a garden or marsh or on a cliff face that hadn't given way with all that record-breaking rain?
The Chiff's broad tail feathers may indicate that
this was a returning adult (male)
It turned out to be quite an eventful week:
Blue Tit - 2 (1) - retrap was a 2010 male
Long-tailed Tit - (2)
CHIFFCHAFF - 2, both males on size (NFY)
Wren - 1
Blackbird - (1)
Robin - 1 (4) - signs that laying was imminent 
Dunnock - (5) - a couple of males with pronounced 'protuberances' but no full brood patches seen so far or nest building (they can be sneaky)
House Sparrow - 1
Pied Wagtail - 1 (NFY)
Chaffinch - 4 - 3 of which were 'big' adults
Greenfinch - 1
Goldfinch - 15 (12) - probably a third or a quarter of what was around; oldest bird was from 2011


Immature Siskin - a few unmoulted median coverts
and a 'full set' of juvenile greater coverts
Siskin - 14 (5) - many passing through, plus a few "stayers" of recent origin
Bullfinch - 2 more males
That makes 44 birds ringed, 30 individuals recaptured; =74 of 14 species this week, 2 of which were new for the year (NFY)

Immature Bullfinch with 4 buff greater coverts


The ubiquitous Dunnock!

Everybody's favourite - the Bumbarrel
(Long-tailed Tit)

This unfortunate male Robin (from next door)
had lost its tail feathers a short while ago.
The Sparrowhawks have become very active around here this week, I notice.

Next week's plant will be Euphorbia - and I'll explain why then.

End of a difficult summer

Ringing activities have been confined to the garden/orchard these last 8-9 days. It has been somewhat different for the time of year when compared to other years. So far, there has not been an appreciable movement of Chiffchaffs and Blackcaps hereabouts. In part this may be attributable to the low numbers of Blackberries that have ripened so far, which, apart from providing sugar rich food for migrating birds, also attract significant numbers of diptera and other insects for these travellers to feed on. Also in the boundary hedge, our Honeysuckle has a profusion of berries but they are not palatable yet.

Honeysuckle berries
Back to the species list for this time period. For the sake of a couple of nets open for a couple of hours most mornings (commencing about half an hour after sunrise), it turned in a reasonable total of 28 new birds and 18 re-captures across 11 "garden" species.

Blue Tit 2 (2) - 3 young birds (2 potential males, 1 potential female) plus a 2CY male
Great Tit (1) - ad. male, ringed in the spring
Blackcap 3 - a handsome young male, & 2 females undergoing PJ moult
Wren 3 - all unmoulted juvenile males (on size & weight)
Blackbird 2 (2) - 3 young birds & a 3CY male
Robin 3 (3) - juveniles & post-nuptial females
Dunnock 1 (1) - 1 juv., 1 2CY in moult
Chaffinch 1 - juv. male at the replacing its ogc's stage (2ogc). This bird had replaced a few tail feathers (retrices) on one side. The photo shows the differing shapes between juvenile feathers (pointed) and replacement/adult ones (more rounded)

tail feathers (LHS) contrasting with the pointed juvenile ones

Greenfinch 4 (3) - 3 females, 2 males & 2 juv. males
Goldfinch 9 (6) - in the last 2 days - 7 moulting adults & 8 youngsters in PJ moult.  The adults all had 2-4 old outer primaries and 2-3 growing feathers. They had all begun to moult their secondaries, too. Previously, almost all recent birds have been juveniles in entirely juvenile plumage (before the PJ moult starts)
Siskin 1 - a juvvy juvenile (i.e. recently fledged!) and female.

This week's juvenile female Siskin

This small group of eighteen re-traps has provided some interesting data. 

Firstly, a female Robin (L601), ringed as a juvenile here in early July 2011, goes missing whenever she is nesting. In mid-April 2012, she was caught three days apart with a vascularised brood patch, indicating that she was starting to incubate. This was just before our big "downpour" (= major flood). She was not re-caught for a further 162 days (or 23 weeks) when she was coming to the end of her complete, post-nuptial moult. But her brood patch was still visible, although feathering up. Between these two dates it is wholly possible that she reared three broods, which is quite normal for a fit member of the species, providing there are no mishaps.
In 2013, however, she was caught in mid-March and mid-April. Between those dates, going by her brood patch, she had laid, incubated and hatched a brood. This struck me as "odd", since the weather had been cold (but dry) up until the end of the first week in April. Perhaps cold-and-dry is preferable to mild-and-wet for starting a brood of Robins. Anyhow, she wasn't to re-appear for another 106 days (15 weeks), time enough for another two broods. Once more she was completing her annual moult, just some body feathers to finish changing, and some 5-6 weeks earlier than last year. 

Next, male Blackbird (LC36), ringed as a 1CY bird in mid-November 2011, is a regular visitor to the garden and can be recognised by his plumage pattern (which is less obvious since his latest moult). Last year he disappeared for 373 days (29 weeks). He was last spotted the day after the big "downpour" and returned about the time the rains eased off. During his absence, we had 711 mm of rain (28 inches), which is 55% more than normal. I wonder what he was doing and where he went to escape the waterlogged soils?

Then there is a Greenfinch (TL94). First ringed as a 2CY female on my birthday (mid-Feb) 2012 and not seen again until this week, 568 days later. The weight was the same and the wing length a tad longer, and she was starting her annual moult. Has this bird been around all the time or does she just come for the winter and the sunflower hearts?

Lastly, the Goldfinches. Six of those adults have a record. X843 is a 2010 male bird that hasn't been recorded since mid-June 2011, a gap of 820 days. His wing length is 1mm shorter than when he was a juvenile; a normal occurence in this species, whereas in some species it increases with age (e.g. tits). X882 is another male, born in 2009 or earlier, that was ringed in April 2011, re-caught in May 2012 and then again this week. He is currently in the 2nd stage (of 4) of replacing his primaries. Male L713 and female L963 were both immature birds when trapped in 2011. Neither have been seen since, a gap of 765 and 671 days respectively. Now in their third year, they were moulting and are 1 gram heavier than when they were young (approx. 7%), in keeping with the other healthy birds. The other two, males Y819 & Y930, were caught during last winter when their weights were higher than they are now; the current night time temperatures are 7C higher and daytime ones 13C higher, which explains the need for carrying extra fat in winter in order to keep warm overnight.

The future looks bright!

Recently built & lined HOUMA nest
Not least because of this emblem of good luck that has appeared outside our bedroom window!

We have had a couple of sessions down at the meadows during the last week, but today I noticed that they had been in behind us and cut the hay, which was over 1 metre high in places. This bodes well as we can now get in to the whole site and, what's more, open up some old stream-side racks where there is more cover and little disturbance. Just in time for the Willow and Sedge Warblers to arrive.

For both sessions, we placed a 40' net across the ford and three nets "in the bushes" where we know we will catch - when the season picks up, that is. A third effort consisted of an early foray into the garden before the local workmen started about their business. The abnormally clear and hot weather is making the birds reticent to even come for food, our local Pied Wagtails being an exception.

The effects of last year's wet spring and summer can clearly be seen in some species, as can the fierce winter the year before. So far this year, things are not too bad. The Sparrows certainly love the drier weather and the heat.

More ringing - after I've done some "habitat management".
