Sauntering up to the Summer Solstice

This post covers the three week run-up to the longest day.

Things are busy in the garden - grass to manage, hedges to cut, borders to weed, soft fruit to pick, black-fly to purge, vegetables to tend, water and harvest, and so it goes on. At least the new potting shed is finished and the greenhouse glass repaired.

The birds have been busy too, mostly feeding their young on either natural food or that which I have provided. So far this year, I have gone through 120kg of SFH, 25kg of suet, 15kg of 'finch seed' (fine stuff) and 10kg of dried mealworms. Haven't counted the packets of sultanas! And dread to think of the cost, too. However, time to replenish stocks!

From now on, the amount of bird-food that I will be putting out will drop off considerably, allowing the birds to return to their natural diet in the countryside/farmland/housing estates. Come November, when the fog and first frosts should appear, I will start feeding more heavily. I find that the greatest demand is either during periods of snow or lengthy frosts and immediately prior to and during the breeding season. By easing off, usually by putting out food just the once 'early doors', the birds are driven to follow their natural instincts for the rest of the day. This weeds out "the chaff from the straw", leaving the fittest to make it round to next year's breeding season. 

For Goldfinch aficionados, have a look at Peter Alker's blog here; you might want to tear out the id pages from Svensson after reading this.

Now for some pictures of very young birds that have been caught recently. With still a lot of growing to do, especially of their flight feathers, it's a marvel that they manage to fly so strongly. We quite often find them high up in the nets.

A really good total for the time of year - often we are away for a week in June, so the fact that we weren't this year might have helped!

200 new birds and some 40 birds from previous.
Herring Gull - 1; a beautiful adult in moult
Woodpigeon - 0; couldn't get to it in time!
Collared Dove - 3;
Gt. Spotted Woodpecker - 2; a pair busy provisioning their young from the feeder
Jackdaw - 1; a youngster
Rook - 1; a too enthusiastic female
Blue Tit - 16 (1); a male from November 2011 (4M)
Great Tit - 12;
Swallow - 3; a first brood about 10-12 days old
Long-tailed Tit - 19 (3); all in one go!
Blackcap - 4 (2); mum & dad first, then four youngsters
Nuthatch - 1; a juvenile was an unexpected first for the garden (doesn't breed in our tetrad, a 2x2km grid square)
Wren - 2;
Starling - 5;
Blackbird - 13 (4); two birds from autumn 2013
Robin - 13 (5); our old female yet again (born here in spring 2011)
Spotted Flycatcher - 2; a pair caught together late morning on the 7th, another first!

(not separable on plumage)

Dunnock - 11 (4);
House Sparrow - 32 (8); oldest a 2012 youngster
Pied Wagtail - 1; "old peg-leg", an adult (3cy) back in July 2012
Chaffinch - 6  (2);
Greenfinch - 28 (2); the real surprise - lots of new young birds
Goldfinch - 22 (8); just 3 adults - that were all male
Siskin - 5;

Over the half-way mark (750) for new birds this year and hopefully about ten more species to get as well, going by previous years. Nothing's  guaranteed in this game though!

PS. I buy much of my bird-food in bulk direct from the importers/processors/wholesalers to reduce costs. It is stored in plastic dustbins to deter the Wood Mice.

The last days of (meteorological) spring

The Met. men start off their summer statistics from today - but the gardeners will wait another three weeks until the summer solstice before they agree on that. At least we shouldn't get any frosts for the next three months. Cold rain, gales, low cloud perhaps!

The birds are either busy nesting, i.e. sitting on eggs for the first or even second time, or trying to find enough food to satisfy their hungry chicks, or even trying to educate their flying offspring in the ways of this very human dominated world. This gives us ringers a warm feeling, as we should be kept very busy ringing the next generations at this time.

Pullus Blue Tit - ca. 10-11 days old (May 2015)

We had a trip to the Field Studies Centre, ostensibly to ring some tits in a box. Unfortunately five eggs didn't hatch, leaving just three pulli alive. The cold weather and the rain that washed many of the insects off the trees have certainly caused their stunted

growth; they would normally have been much further advanced by this time. We played around with some potential net sites and were comforted with a further eight adult birds, including the mother of the chicks. It's all mod-con here!

Nettlecombe base

The Jackdaws are coming "en masse" every morning as soon as I put out the suet pellets on the several bird tables. They are quite acrobatic and manoeuvre around the nets and other obstructions quite intelligently. One, maybe two, got caught out but I was unable to retrieve any for ringing this time. Slippery as an eel!

The "bright spot" of the last fortnight has to be the large number of House Sparrows caught, now amounting to 77 'new-for-year' individuals.

In all, we ringed 82 new birds, 11 of these at Nettlecombe, and handled another 42 separate birds. 

Recently fledged 'spotty' Dunnock.

Collared Dove - 1; an early youngster starting wing moult

Jackdaw - 0; nearly but not good enough

Goldcrest - 1; adult female with a classic "club" tail

Blue Tit - 9 (1); elderly male from 2011

Swallow - 1;

Wren - 2 (1);

Starling - 3 (2); a single juvenile so far

Blackbird - 3 (7); a third juvenile male and nine adults

Robin - 5 (6); 7, 4 new, were juvs.

Dunnock - 9 (1); 9 youngsters and a 2CY female (caught 3 times)

House Sparrow - 23 (10); 27 young birds ringed so far in 2015

Chaffinch - 3 (1); 3 juvs, the first on 25th

Greenfinch - 8 (4); 6 new & 2 recaptured juveniles; oldest bird ringed as adult male in November 2012

Goldfinch - 11 (8); 10 new juveniles to add to the 6 already ringed;
oldest bird was an immature when ringed in November 2012

Siskin - 3;

A 'this year's' Siskin

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

What's doing? Not a lot!

It has been a tad breezy down this way lately, what with the wind coming from the north-west down the Irish Sea. Although that means the old orchard net is sheltered somewhat, the new orchard net (the orchard is new-ish, not the net) does billow a bit at times. Just have to keep an eye on things, that's all. 

August is the month of the House Sparrows. This year seems to have been a good one for them. A few more and it'll be a 'ton-up'. All youngsters, of course; you won't catch a wily adult hitting the net very often, or even a second time offender amongst the teenage ranks!

Birds of some interest (that means I don't catch them very often) this period include another Collared Dove (makes three this year), a Woodpigeon, a Sedge Warbler, a Garden Warbler and the eleventh Pied Wagtail of the year.

Altogether, there were 16 species and 63 new birds that were ringed. Ten species also had re-traps, amounting to 31 percent of the tally. This is pretty normal for me and this type of general ringing. Its the same with the Constant Effort Sites programme with which I was associated for many, many years. On the other hand, some ringers/groups target certain species at particular times of the year and their re-traps tend to be year-to-year  controls and a lot less as a percentage of their overall, annual totals. They usually make up for it with many more recoveries!

To the chase! All juveniles unless indicated otherwise.

Woodpigeon 1 - adult

Collared Dove 1 - adult

Wren 3

Dunnock 2 (2)

Robin 8 (2) - r/t adult female 1 year old

Blackbird 2 (2)

It's 'Pony Week' - so all efforts, ornithological or horticultural, confined to the garden this week. I might be able to do something in the meadows after that, provided the remaining horses/ponies are more interested in grazing than seeing what I'm up to.

Two weeks on ...

... and we had 46 mm of rain in 5 hours. That's the same as the ten year average, all on the first day of the month! More thunderstorms have ensued since. Anyway, back to birds and the last 18 days.

Garden-wise, it's the House Sparrows that have been most in evidence, as they always are at this time of year with this year's youngsters looking for their next meal. They don't go near the feeders, as a rule, but prefer the bird table, either ours or our neighbours. That means I catch them as they cross the open part of the garden, where I don't usually net. There is still an active Blackbird's nest somewhere; both mum and dad collect mouthfuls of suet pellets early doors and scoot off with them.

Cinnabar caterpillars on Ragwort
(click to enlarge)

It's been a very good year for butterflies and moths. We have had many more Cinnabar moths this year and, with a small patch of Ragwort at their disposal, hundreds of caterpillars have emerged. Right now, they are looking for somewhere to pupate.

There has been a lot of Herring Gull activity post fledging, all ages readily coming to the broken up Hovis crusts I deliver. One pair are still attending their nest site, which they haven't used, just played about with a few bits and bobs of rubbish to form a base. The building's owners usually take the old nest away each autumn, as do many owners/occupiers. Still doesn't stop the birds from returning to their allotted spot each spring, though. 

There was a flurry of Swallow activity last week with 26 birds hunting over the garden one evening. Down on the meadows the number of individuals hawking for insects has decreased noticeably. The meadows are fully cut and part has been "mown" ready for the inevitable gymkhana that the owner's sister puts on for her young female riders. The better news is that the owners are going to fence off and gate the southern two meadows (that includes the ford) and resolve to contain the various horses in the larger northern section (that also has a crossing). Most of the site that I use could be available for ringing all year round next year.

Despite various restrictions, mainly on the domestic front, I have still managed to ring 98 new birds this period and re-capture another 26 individuals, (I discard any same period re-traps), of 19 species as under. The list is dominated by juveniles, before, during or after their post-juvenile moult.

 Today I spotted (pun) my first local flycatchers. They, a pair, were carrying food for some youngsters tucked away somewhere around the old water-wheel site that served Egrove Farm mill. Couldn't stop - other half about to leave for Norfolk.

Off-site I did manage to meet up with two old Beds birding mates (DJO & DK) for a pint and a curry like the old days. Hilarious.

Summer sunshine

The weather has been good to us; just one morning when we had a heavy shower that brought 11mm in one hour before breakfast. Our garden thermometer has measured a max of 23C to 29C in the shade before 2pm every day since last time.

Following on from the sad tale of the other two Herring Gull chicks, I can report that the third one managed to fledge successfully last week - not before I was able to ring it when it was in the throws of mastering flight. They normally spend two/three days practising when it is possible to throw a towel over them and pick them up.

42 day old Herring Gull chick

The garden nets have been moved around a couple of times, with one always in the bottom of the orchard. The sun has meant an early start and an equally early finish by ringers' standards. With more racks cut out down the meadows by yours truly between garden chores (sweaty work), we were able to give that a couple of goes, too. The net runs have never exceeded 180' at either site so far, giving a max. of four nets operated.

A problem at this time of year, especially if ringing very early or very late in the day, is the possibility of catching, inadvertently, a bat. I did just that and, after disentangling it from the net, I left it to come to its senses on the potting shed door.

Small bat (Pipistrelle?)

I was lucky enough to re-catch the juvenile woodpecker in the garden again. As you can see from the photograph below, "it" (still unable to sex the bird) had just begun its post-juvenile moult. The photo shows the contrast between a new, red, adult under-tail covert and the pink juvenile ones.

Juvenile Great Spotted Woodpecker

 "Fairmead" - 113 birds of 17 species, 72 new, 41 retraps (+10 re-handlings): the vast majority were young birds. I haven't caught any Jackdaws this year (yet), but there were >105 sitting on the roof the other night.

Herring Gull - 1, 41 day old chick about to fledge (see above)

Gt. Spotted Woodpecker - (1), the previous juvenile, just starting its first partial moult

Magpie - 1, first juv we've ever caught here

Blue Tit - 9 (4), juvs plus one r/t 2CY moulting female, r/t adult male in heavy moult

Great Tit - 5 (2), juvs

Long-tailed Tit - 1 (5), juvs & 1 r/t adult female

Wren - 2 (1), juvs, probably males (on size)

Blackbird - 10 (1), 8 male & 2 female juvs plus a new 3CY+ male

Robin - 3 (4), 4 juvs, 2 r/t females, 1 r/t male

Dunnock - 3 (3), 2 r/t females, 1 r/t male

House Sparrow - 10 (9), 6 males (1 new), 4 females, the rest = juvs

Pied Wagtail - (3), adults

Chaffinch - 1, a lone 3CY+ male

Bullfinch - 6 (2), 2 new females, 2 new males, 2 old males, 2 juvs

Greenfinch - 4, all males, 1 male 2CY

Goldfinch - 7 (3), 1 r/t male, 1 new male, the rest were unsexed juvs

Siskin - (2), a possible pair

Meanwhile, down the road, our species make-up is profoundly different at this time of year. I got the most enjoyment from re-catching the adult Dipper (below) that was ringed as an adult in May last year. This time it was actively moulting, as can be seen if you study the picture closely. Visible are the contrast between old and new primaries, a row of, as yet, unmoulted median coverts and some new, black feathers appearing in the crown. 

3CY+ Dipper in active moult (mid July)

"Egrove" - 50 birds of 14 species, 42 of which were new birds; all juveniles except where indicated.

Blackbird - 2 (1), a new 3CY+ female

Song Thrush - 1, the first for the year

Robin - 2, 

Dunnock - 3 (1), only 1 juv, the rest adult males with pronounced cloacal protuberances

Goldfinch - 1 (1), the r/t was an adult male

I don't split the ages of adult Goldfinches into 2CY and 3CY+ at this time of year (May - August) as differentiation in feather age is nigh on impossible. All adults revert to Euring age class 4 anyway after the moult is complete since they all have new flight feathers.

Well, that's that. The contractors are coming in to mow the rest of the hay crop this coming week which should enable us to visit more of this longitudinal site. I will report back when we have some more news to share with you.

Another beginning on the meadows

The sun shone without any rain in the air for 17 days during the last 3 weeks. Now the weather has broken and the hay that hadn't been brought in is flattened. So far it had been a bumper year of top quality hay. There may be a chance for a recovery this coming week. It'll make life easier for us to get around the meadows, that's for sure.

I digress. We, I say we because I can now get out with a trainee as I'm feeling up to it at last, made our first visit of the year to the local meadows yesterday. The work needed to open up some racks, both new and old, is daunting for these old bones though so we started simple - two nets in the trees and one across the stream.

But back to the beginning. I managed some garden ringing, both before and after our week-long trip to Penwith (the tip of Cornwall). Things started very slowly but by the time we got back, there were a lot of young birds independently on the wing. Naturally, quite a few of these succumbed to being ringed or though one or two thought otherwise.

Juvenile Great Spotted Woodpeckers are easily recognised; two pointers are visible with the naked eye from a distance. They all have a "red top", whereas the adults are black-capped, and the under-tail coverts are a delicate shade of pink, not 'post office' red. Close up, you can notice a dull eye and small, white tips to the primaries, too.

Neighbour John, from the far end of the village (but a different parish), caught a Kestrel of mine  earlier in the week that was ringed as a full adult male (t'was nesting nearby). It had only shifted 1.8 km in the 331 days since its release. As I haven't seen it hardly at all this year (on my daily, repetitive walk), I assume it has chosen either another nest site or a new bride. On the same day, he ringed 'a large number' of young Blackcaps, one of which was in my hand by the stream on our first outing here 3 days later. The only species we handled that day were Kingfisher, Chiff., Blackcap, Grey Wag., Blackbird & Goldfinch. We did see a Jay and a Little Egret and heard a Dipper.

Aggregated list of 86 new birds ringed plus 13 ringed individuals, excluding the local inter-changes above, covers 19 species.

At long last - a juvenile Siskin

Greenfinch 11 - 6 boys, 4 girls and a grandad

Goldfinch 6 (3) - the r/ts were all 2CY males

Siskin 1 - juv
Just 9 of these birds were adults. I doubt if any of the juveniles has had a chance to move more than a couple of miles yet so far this season. Even the Lottis!

Adult female Rook
This bird was in full wing moult and still had a bare but wrinkled brood patch

I/we look forward to a few decent sessions down on the meadows before the horses are turned loose from their summer paddocks. Although the site is divided into six fields, there are no gates and two fords! This is limiting in what we can usefully do. We'll have to hurry up and catch those young Kingfishers then! We'll let you know.

Someone's first Kingfisher?

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".

Hard cheese

Hard graft, more like, for a few more weeks to come. My absence has been forced by a computer "mal-function", commonly known as the OS going nutty during a Win7 update, forcing complete closure and re-programming. Still - we're up and running now, but minus a large chunk of my ringing database. Hence the introductory comment.

A few ringers have been remarking on the poor breeding season, with special regard to provisioning of the young with food. Irregular feeding results in poor quality plumage in extremis but is generally evident in the growth bars present in the flight feathers. (That includes the tail). Sometimes the feathers lack pigment, giving the young birds an uncommon plumage hue. Their poor quality can lack insulation properties, making life even harder than it should have been as they enter the world. Here are two of the examples I have handled  recently.

Well, it's not been all bad. I've managed to ring in the garden in between fixing "the box" and other duties, wind and sun permitting. Suddenly, it seems as if the one-time nestlings have all popped out and are having to fend, in part, for themselves. I've racked up 94 new birds since being "off air", with another 21 recaptures. Today, I sloped off down to the 'river' after a three week gap, and added to the garden mix by way of Blackcap, Dipper and Swallow juveniles.

Juvenile House Sparrow

Juvenile Siskin

Juvenile Goldfinch

Things are very quiet down there, with many birds singing heartily still, but very little evidence of any young about, excepting some Blue Tits, ... but the wind didn't help.

The totals over the 16 days were as follows; no double-counting. The re-traps, by and large, were adults

Jackdaw 1 - a cocky male

Blue Tit 9 (1)

Great Tit 7 (1)

Swallow 1 - juv

Blackcap 1 (1) - first juv and a 2010 male

Wren (1)

Dipper 1 - second juv

Blackbird 15 (4) - 7 were adult

Robin 7 (4)

Dunnock 5 (5)

House Sparrow 15 (2) - the r/t's say why I don't do a RAS!

Pied Wagtail 1

Chaffinch 5 - plus 2 with leg mange (unringed)

Greenfinch 5 (1)

Goldfinch 17 (1)

Siskin 4 - all juvs

16 spp., 94 new, 21 r/t 

The last bird of the day was a re-trap, male Blackcap. He was originally ringed, as a 2CY bird, in virtually the same spot, on, to all intents and purposes, the same day two years ago. It was only the third ever visit I had paid to the site and the first time I had set a net between those trees. Nine of the 12 Blackcaps I caught that day were juveniles. Not so this time. I do love my Sylvia warblers. 

I'll try to get another bulletin out before our German & Austrian visitors arrive in eleven days time. So long.
