Boring? Never.

I’d met up with Andy for another ringing session at Oakenclough and where surely we would find a few fresh migrants on this the Fifth of April? The wind was in the North-West and at 0630 and 0.5° it wasn't especially warm. 

A glance at the weather map portrayed a stream of warm air partly headed our way from Iberia with maybe an outside chance of a few new birds although few migrants had yet reached the North West. 

Thursday 5th April 

Our catch was on-par for recent weeks. In other words not so good with just 12 birds caught and still zero warblers - 3 Siskin, 3 Goldfinch, 2 Blue Tit, 1 Coal Tit, 1 Great Tit, 1 Lesser Redpoll, 1 Dunnock.

We don’t catch many Dunnocks at Oakenclough but today’s bird proved to be a female in early breeding condition.

Dunnock

The name Dunnock comes from the old English words dunnakos/dunoke or donek, meaning ‘little brown one'. Dun = dingy brown, dark-coloured. Ock = diminutive. Its scientific name Prunella modularis translates as ‘little brown singer'.

It has other English and Irish names such as the wren's brother, mother-in-law, field sparrow, black wren, grey robin and hedge warbler. In Scotland one of its common names is blue-dykie - more of that later.

The Dunnock is the persona non grata of the bird world - mostly uninteresting to birders, ignored, unloved and unwanted; especially so when out it pops from the hedgerow where a rare LBJ is rumoured to be. The Dunnock deserves few mentions on bird blogs, barely a frame on You Tube and never a photo on Bird Guides’ Best. And wait in vain for a pager message or urgent tweet about the dismal, drab and dowdy Dunnock.

A Dunnock spends its days lurking mostly unseen in dark corners of suburban gardens or feeding surreptitiously under bird feeders when the glamorous birds have left the feast.  Its song is unhurried and unremarkable; a warble which to the inexperienced or hard-of-hearing can be confused with the Wren, Robin or Common Whitethroat but one which lacks the Wren's intensity, the Robin's sweetness or the scratchy tones of the Whitethroat.

But fear not dear reader. The lacklustre Dunnock does have a trick or two up its feathered trouser legs, as many a ringer will relate. The identical male and female Dunnock are to all intents and purposes monomorphic - identical when even simple biometrics prove unhelpful in separating one sex from the other. Until that is the breeding season when the male displays its most obvious attributes that go toward the legendary sex life of the dreary old Dunnock. Multiple mating systems including monogamy, polyandry and polygyny - you name it, they do it.

You see, there’s more to a boring Dunnock than meets the unwelcoming eye. I do think that Mr Dunnock would agree.

Trying

I missed two ringing sessions. Tuesday was half-term duties and then on Wednesday I had to wait in for the heating engineer. 

Andy was out on both days when he caught the first Chiffchaff of spring, several Meadow Pipits, half a dozen each of both Siskin and Lesser Redpoll and the usual bits & bobs of Dunnocks, Robins and Blue Tits. 

Wednesday was a chance to catch up with spring and the example set by Andy. We met up at 0630 to a gentle south-easterly and hopeful vibes, but 2° with an ice warning on the dashboard said otherwise. And so it was, with just 7 birds caught in more than three hours - 3 Goldfinch, 1 Siskin, 1 Coal Tit, 1 Meadow Pipit and 1 Goldcrest. The latter was our first of the spring and now some two weeks later than normal.

Meadow Pipit 

Goldcrest 

Siskin

The tiny and quite stunning Siskin is a species that ringers like to catch. 

It is also one of the bird success stories of recent years. Since the 1950s the maturation of new conifer plantations has aided the spread of breeding Siskins throughout the UK from their previous stronghold in the Scottish Highlands. 

The Siskins' habit of using garden feeders, especially in late winter, has developed since the 1960s and despite many winter birds in gardens migrating to the Baltic region to breed, may also have helped boost the UK breeding population. 

 The 1988-91 Breeding Atlas identified a major expansion of the breeding range into southern Britain and subsequently there have been further considerable range gains, especially in the south and west. The 1970s and 1980s saw more Common Bird Census plots occupied but samples were insufficient for annual monitoring until Breeding Bird Survey began in 1994. 

Results since then show parallel fluctuations of populations both in England and Scotland. To some extent this probably reflects the occasional large continental influxes affecting spring numbers on a broad UK scale. 

As might be expected from the figures above, this morning’s visible migration was nil. But all was not lost. On the way home and at 11 am I spotted a day hunting Barn Owl across distant fields. I spent twenty minutes or more watching as the owl ranged far and wide, high and low in search of a meal before it seemed to head back home.

It wasn’t the most successful morning but nice to finish on a Barn Owl high. More soon – stay tuned.

Mars And Venus

Saturday morning and at 5am the alarm buzzed in my ear. Fifteen minutes later I was washed, dressed and had made a flask of coffee for the 40 minute journey to meet Andy at Oakenclough. 

By six there was zero wind and a few spots of rain. The rain was nothing to worry about as it quickly petered out and left perfect conditions for ringing. Once gain the ringing was very subdued with nothing in the way of migrants as the weather south of here continues to block migration. 

We ringed just 14 birds of 4 species - 8 Goldfinch, 3 Chaffinch, 2 Coal Tit, 1 Robin. For this time of year it is quite unusual that we caught zero Lesser Redpoll or Siskin today. Even the two Siskins we saw were probably fairly local wintering birds. 

The male symbol ♂ is the astrological symbol for Mars and the female symbol ♀ is the astrological symbol for Venus. Of the three small finches it’s the Goldfinch that is the harder to sex. While male and female Redpolls and male and female Siskins are quite different in their respective looks, the distinction between boy and girl Goldfinches is less obvious. 

To decide ♂ or ♀ Goldfinch we use the amount and shape of the patch of red feathering above and behind the eye combined with the colour of the nasal hairs. Wing length is an additional aid to sexing with a boy wing mostly longer than the girl equivalent, despite some mid-range overlap. The often slightly larger overall dimensions of a male can carry over to the bill whereby the bill of a larger male can be strikingly long. 

None of the above methods are of much use in the field and certainly not in the autumn with moulting adults or brown juveniles that lack any head colouration.

A local person we saw this morning today told of two regular Siskins on his own garden feeders. He knows of a nearby bird enthusiast and a garden well stocked with feeders that holds many more Siskins, Chaffinches and even a handful of Bramblings. The latter species has been very scarce during this Lancashire winter.

Apart from the ubiquitous Goldfinch The best I can do in my own garden at the moment is a couple of wary Tree Sparrows that come to snatch a few grains of millet and an equally shy Stock Dove.

“Otherwise Birding” today consisted of watching a pair of Sparrowhawks in display, 2 Pied Wagtail, 2 Mistle Thrush 1 Raven and 1 Great-spotted Woodpecker.

Truncated Morning

Tuesday and the wind had changed direction from the recent Siberian blast to an almost balmy north-easterly of 8 mph. Even the temperature picked up to 0.5° at 0630 but the wind chill made it feel more like minus 15°. 

I’d met up with Andy at Oakenclough for a ringing session. Andy still sported a tan from his week in Abu Dhabi but there was no tee shirt or shorts to be seen. 

On our last visit here on 7th March, Another Bird Blog, we caught the first handful of Siskins and Lesser Redpolls of 2018, so we hoped to improve on this. However it was not to be as the wind soon picked up to 15 mph to truncate the already quiet session. 

We ringed just 11 birds – 3 Lesser Redpoll, 2 Siskin, 2 Blue Tit, 1 Chaffinch, 1 Blackbird, 1 Great Tit, 1 Goldfinch.

Chaffinch 

Other than the finches, there was little evidence of migration with “other” birds seen limited to local inhabitants; 6 Oystercatcher, 2 Buzzard, 3 Pied Wagtail, 3 Mistle Thrush, 1 Grey Wagtail, 1 Raven, 1 Great-spotted Woodpecker. 

The early finish allowed a leisurely drive back over the moss roads where I came across 6 circling Buzzard and 1 Kestrel. Skitham Lane saw 16+ Ruff on a still flooded field some 500 yards from the road but in an isolated and unapproachable field. 

I stopped at Gulf Lane, Cockerham to see how many of our wintering Linnets are still around to find just thirty plus, a figure that suggests there may be no more ringing opportunities. Hopefully the 237 Linnets ringed this winter will provide information on their whereabouts at later dates. 

Thanks to one of my readers I discovered that today March 20th 2018 is World Sparrow Day celebrating the relationship between humans and sparrows. There are over 40 species of sparrow in the world.

Something For The Weekend

Spring has yet to arrive. In fact the weather at the moment here in Lancashire is still like winter with low temperatures, biting easterly winds and even snow predicted for the weekend. 

Something For the Weekend 

With little prospect of birding or ringing I dipped into the archive for the sunny days of Egypt in 2011. 

The post from February 2011 seems especially relevant now as we in the UK await Chiffchaffs fresh from the wintering grounds, one of the first spring migrants. 

Chiffchaff 

Ringers know that early Chiffchaffs often carry pollen residues on their bills. This pollen was deposited by the feeding strategy known as nectarivory, birds indulging in sipping nectar from flowering plants during which flowering pollen is left on the bird itself, mainly around the base of the bill, the part of the bird most closely in contact with the flower. Nectarivory is also known to occur in some species of bats. 

Chiffchaff 

During the 2011 holiday to Egypt I saw countless Chiffchaffs and also saw nectarivory in action. The number of Chiffchaffs was not entirely surprising as unlike the closely related Willow Warbler which winters mainly in West Africa south of the Sahara, Chiffchaffs also cross the Sahara and concentrate in Senegal, while others remain in the Mediterranean North Africa of Egypt. 

At least 3 often inseparable races breed in the Middle East, collybita (includes brevirostris), menzbieri and probably abietinus and at least two others visit. So at any time, and especially during winter, spring and autumn the origins of Chiffchaffs and race of each individual in Egypt is hard to determine. The latest scientific and perhaps unremarkable opinion is that races of Chiffchaff interbreed freely, thus  making racial definition and identification in the field difficult if not impossible.  

There is no doubt that in Egypt I heard and saw our familiar UK collybita, with both the typical “hweet” call and occasional snatches of “chiff-chaff, chiff-chaff”. I also heard the “squeaky chicken” call frequently and on a couple of occasions, snatches of the fast, melodious song of Siberian Chiffchaff tristis, totally unlike the Chiffchaff song I know but more like a demented Dunnock. 

In Hurghada I witnessed many Chiffchaffs taking nectar, at times the liquid being visibly sipped as birds stuck their heads deep into the flowers, and upon the bird withdrawing from the flower, drops of the nectar spilling from their bill. A particular favourite plant of the Chiffchaffs was a flowering Mexican Saguara cactus shown in the photographs below. In a few of the pictures, by zooming up it is possible to see the nectar drops around the bill.

In the two week trip I had one sighting only of Nile Valley Sunbird, another bird that takes nectar. In view of the tremendous number of flowering plants in Makadi Bay my single sighting was a little disappointing. 

The biggest numbers of Nile Valley Sunbirds occur much further south than Hurghada, but in the last 100 years, helped by the building of tourist resorts, the species has spread from the southernmost parts of the Red Sea and up to the Cairo area where it breeds. I didn’t get to Cairo to look for more sunbirds so settled for my one brief encounter and a couple of distant shots.

Back To The Linties

Linnets have hung around all winter at Gulf Lane but Friday morning and with a gentle breeze from the south east came the first opportunity for a month or more to catch a few. 

Earlier this week when I’d topped up the seed feed there’d been about 120 Linnets in the field, 8 or more Skylarks and 3 Stonechat dotted along the fence. 

I met Andy at 0700 and within ten minutes we had the usual configuration of nets ready for action. The Linnets appeared ravenous as they dived into the area of the food from the off. Well into March, the hungry month for birds, there’s not much of their natural food left so our seed mix is doing the job. 

We had a good catch of 23 Linnets but failed to catch a Skylark; despite two Skylarks being in the net, they both escaped before we laid a hand upon them. The Skylark is the Harrier Jump Jet of the bird world in being able to rise vertically from a standing start, even when partially enveloped by a mist net. 

Skylark

Our catch of 23 Linnets comprised 8 first winter females, 2 adult females, 8 first winter males and 5 adult males. This brought our running total of new Linnets ringed during the Winter of 2017/18 to 237 individuals.

For only the second time at this site and with almost 450 Linnets behind us in two winters, we had only our second recapture – S800285 was ringed here on 2/11/2017 and recaptured today, but not in the intervening period. 

A glance at the coffee stained field sheet from today shows a few large males with wing lengths of 83mm. This was  surpassed by the very last adult male caught at 0930 with a whopping measurement and double checked via Andy as 87mm. Almost certainly this male will be from the Scottish and slightly larger sub species of Linnet, Linaria cannabina autochthona. By the way, and for those who collect such trivia, the old Scottish name for a Linnet is “lintie”. 

Today's Field Sheet

"Lintie"

And now to work for the next hour or so in transferring the data for those 23 birds into the new BTO online database DemOn. 

DemOn - BTO

I knew that 87mm was a big one. DemOn gave me a validation warning.

"Wing-length queried as outside normal range of species – max 86mm"

"Validation warnings occurred when submitting the record. Please check the warnings, and click continue to save the record anyway. Please enter a comment for any warnings that require one before continuing. To go back and edit the record, click 'Cancel' ". 

A ringer’s work is never done but back soon with more news, views and photos.

First Poll

This morning’s ringing session seemed  a long time coming. We more or less abandoned Oakenclough last year after the storms of autumn followed by a winter to forget. But Andy’s done a sterling job with the feeders in the last couple of weeks by enticing birds back on site.

Wednesday dawned with a hint of better to come, a drop in wind speed and our first chance to catch up with small finches on the move at this time of year. Wind began at 6-8 mph from the south east, later 10-12 mph from the west with full cloud cover changing to sunny from the west. 

We met at 0700 and were joined today by Bryan. The session was pretty slow but we caught our first Lesser Redpoll and Siskins of the year together with a slight surprise in the shape of not one but two Mistle Thrushes. 

Fifteen birds caught: 3 Blue Tit, 3 Coal Tit, 2 Mistle Thrush, 2 Siskin, 2 Goldfinch, 1 Great Tit, 1 Chaffinch, 1 Lesser Redpoll.

We’d heard two or more Mistle Thrushes in their usual loud song from treetops and watched as three of them crashed through the site in a territorial dispute. The Mistle Thrush as a very loud far-carrying song.  Click the start button below to hear the distinctive song of Mistle Thrush.

We aged and sexed the two Siskins as one adult female and one first-winter male. They were released together and we watched as they flew off in close proximity. It’s a rule that ringers follow; if males and females are caught close to each other, as they often are, they are released at the same time. The same goes for possible family parties caught in late summer or autun. 

Siskin

Goldfinches look rather splendid now as they move into their summer best. Look at the dark-tipped silvery bill of the male below. 

Goldfinch

The redpoll was in fine condition so early in March. As suspected on first sight and confirmed upon closer examination, it proved to be an adult male. 

Lesser Redpoll

In recent years the Lesser Redpoll has been added to the list of garden finches like Goldfinch, Chaffinch, Greenfinch and Bullfinch. The BTO Garden BirdWatch survey shows a 15-fold increase in the use of gardens by Lesser Redpolls during early spring over the past five years. Having said that, they seem not to occur very much in gardens in coastal Lancashire where I live. I hope they become more common soon. 

Other birds noted this morning: 4 Buzzard, 1 Sparrowhawk, 2 Pied Wagtail, 20+ Oystercatcher, 1 Great-spotted Woodpecker, 8 Lapwing.
