Green And Yellow

In the garden this week have been Greenfinches and a single Treecreeper, the latter species becoming something of a local rarity in recent years, and then close by this morning 2 Great-spotted Woodpeckers, each drumming out their territories. This fine Sunday morning and the final day of school half-term I decided against going birding when all the world and his many dogs would almost certainly be where I wished to explore; instead I decided to try a spot of netting for more Goldfinches and anything else that came along – not much did.

In contrast to last winter, for months now there’s been an obvious lack of some finches in this part of the North West, with just average numbers of Chaffinch and virtually no Siskins or Bramblings. Last year Will and I caught 150+ Siskin and 22 Bramblings in January/February in his garden and at another site near Lancaster. Before today the ringing group’s score sheet read just 2 Brambling and 0 Siskin; until today that is when the Goldfinches brought a few Siskins “pinging” towards the garden Niger feeders, and so fifty days into the New Year I caught the ringing group’s first Siskin of 2012. The Goldfinch total was topped up by 3 more males and a single female.

The morning was warm and sunny and from the tops of the sycamore came the fluty calls of Starlings, noises reminiscent of the Golden Oriole Oriolus oriolus, one of the Old World oriole family, whose kinfolk include the Starling. The Golden Oriole is a rare bird in the UK but a species I became familiar with during 5 visits to India, where many European Golden Orioles spend the winter. It’s also a species I look forward to meeting each year in Menorca, where a walk along quiet paths will unearth a few pairs. Unlike our everyday Starling, the Golden Orioles I see are usually very secretive, hiding out in the tree canopy where the males stay out of sight and the females use their yellow and green colouring to blend in, all in all making the bird almost impossible to photograph.

All was complete this morning when Starlings came down to feed on last night’s left overs of curry and naan bread, allowing me to catch 5 birds; pity they weren’t the yellow variety of oriole, but our own much maligned Starling is actually a very smart looking creature if a tad bit common for most folk’s liking.

Yellow And Red

Following a couple of enforced bird-free days I got to Out Rawcliffe where I topped up the Niger feeders and took a wander around. With the wind finally relenting I put up a couple of nets for a while in hoping for a catch of Goldfinches. I caught just 10 birds and it wasn’t the yellow and red of Goldfinches in the net, but the red of Robins and the yellow of Yellowhammers, with 3 Robins, 4 Yellowhammers, 1 Reed Bunting, 1 Blackbird and 1 Chaffinch.

Goldfinches were strangely absent this morning with just 4 knocking about the feeders with a number of Chaffinch for company. The Yellowhammers I caught were some of the 15 or so arriving to mop up the wheat falling from the shooter’s game feeders.

The single Blackbird caught, a large first winter male, looked very much like a “continental” type, especially with a wing length of 141mm and a weight of 113 grams.

A good wander round the immediate area revealed not much about: 70 Lapwing, 50 Chaffinch, 2 Kestrel, 2 Great-spotted Woodpecker, 3 Skylark, 2 Corn Bunting, 4 Linnet and 4 Reed Bunting. The mild sort of morning induced a few species into brief song, with new ones for my year of Chaffinch, Skylark and Corn Bunting.

I had a glimpse of a Tawny Owl this morning and found four fresh and still damp pellets from where it took off. An owl pellet is the portion of an owl’s prey that has not been digested. Owls swallow their prey whole (they don’t have teeth to chew) and the feathers, fur, bones and other indigestible parts are regurgitated by the owl some hours after a meal in the form of a compressed pellet of matter.

In my picture (double click to enlarge) it is possible to see the remains of a small bird the owl had eaten - bits of feather and the feather sheaths themselves.

Tuesday Tour

Cockerham is always good for the resident Little Owls and when I turned up there today one of the pair was searching the peaty soil for a meal. When the bird spotted me with the car window wound down it flew back up to the nest box and just glared at me for interrupting the planned meal. Except for a number of Lapwing and 50+ Curlew there wasn’t much else on Moss Edge, there never is nowadays since the change in agricultural practice to silage and spring sowing. In the old days Moss Edge was THE place to see the early year wild geese, sometimes from the hay loft of a birder-friendly farmer’s barn as the geese picked over the remains of the previous year’s potato crop.

Having toured Moss Edge the main road back to Pilling alongside the wet fields was more bird friendly, but being biker mile/death row, a little too dangerous to stop apart from being able to pull into the junction of Gulf Lane. Along here I picked up 1 Merlin, 1 Kestrel, 30 Golden Plover, 900 Curlew, 14 Oystercatcher, 40 Dunlin, 300 Lapwing and 25 Redshank.

At Lane Ends the pools are now thawed with the result that 2 Tufted Duck have reappeared but not much else unless you count the Mallards of dubious origin. At least 20 Chaffinch here, 6+ Blackbirds, 2 Little Egret and 1 Cormorant.

Both Backsands Lane and Fluke Hall Lane proved bird productive, with a second Merlin, 2 more Kestrel, 300+ Lapwing, 18 Golden Plover, 95 Dunlin, 45 Redshank, 2 Snipe, 25 Oystercatcher, 10 Eurasian White-fronted Goose, 3 Skylark, 1 Pied Wagtail and 190 Shelduck. With 50+ additional Curlew it took todays count to over 1000 for the species. The light was poor again today, hence the ISO400 and resulting noise on the Curlew picture.

With more grey skies and breezes promised for tomorrow, I may take a day off, but you never know – stay tuned.

Monday Meander

It was a top up day at Rawcliffe today, filling the Niger feeders which swayed about in the stiff breeze, the level of seed down a little and with just a couple of Goldfinch and a single Redpoll again, probably not worth netting just yet. There's a large flock of approximately 140 Chaffinch and 10/15 Yellowhammers knocking about the farm, some of which visit the shooter’s feed bins and my feeders in an irregular manner when they are disturbed by passing vehicles from the maize stubble.

A walk across the moss showed a good selection of species to be around. The noise from several hundred jackdaws and other corvids made me look over towards Pilling Moss where I spotted the Hen Harrier heading north towards Skitham Lane. This harrier hasn’t ventured far during the 4 or so months it has been around since I first noted it on 26th October 2011, it just seems to carry out circuits of the moss bounded by roads north, south, east and west. After seeing the bird dozens of times throughout the winter I still haven’t got a decent photo, and it’s no coincidence, the bird is just good at avoiding the human race.

Hen Harrier

Over towards the west along a field boundary I could see a 90 strong flock of Corn Buntings, 75 or so Linnets and 145 Lapwings. These Corn Buntings plus many others seem to have arrived recently in the mild Fylde as a result of snow and ice elsewhere, but it would be wrong to assume they are all local birds, so scarce are Corn Buntings at most times, with one or two pairs only breeding on this particular farm. Within a week or two we should hear the "jangling keys" of the Corn Bunting. Click the "xeno-canto" button to hear the song.

I spent some time looking across the fields waiting for the harrier to reappear, but it didn’t and in its place I saw 2 Kestrel, 1 Sparrowhawk, 4 Grey Partridge, 3 Buzzard, 8 Stock Dove and 2 Skylark.

Kestrel

I stopped again further south to count birds on the winter feed track and beyond: 140 Tree Sparrow, 9 Reed Bunting, 3 Yellowhammer, 10 Skylark, 15 Chaffinch and 1 Great-spotted Woodpecker on the peanut feeder.

Mixed Bag update

This is a little update from yesterday and today, a mixed bag of birding with a spot of ringing thrown in.

Today we had to travel up to Lancaster City so first called in at Knott End followed by a quick look at the geese at Lane Ends, Pilling before heading north up Death Row/Biker’s Mile towards Lancaster.

The tide was pretty much in at Knott End, all the better then for a quick count of stuff beyond the Bourne Arms, on the jetty itself or along the water’s edge, passerines and shore birds: 23 Turnstone, 9 Sanderling, 18 Redshank, 45 Shelduck, 2 Pied Wagtail, 9 Twite, 1 Black Redstart, 45 Shelduck

Twite

Eider

At Lane Ends 7 Eurasian White-fronted Geese were the nearest of a pack of about 300 geese at Backsands Lane. It’s difficult to get a shot of more than 3 or 4 of the white-fronts together because not only are they strung out across several yards, but like all crowds of geese some feed heads down while others stay heads up on the lookout for predators, until after a few minutes it’s time to reverse roles when “feeders” become “sentinels” and vice versa.

Eurasian White-fronted Goose

Back home I’ve caught more Goldfinch and a couple more new female Blackbirds; in the continuing cold, both thrushes carried fat scores of 3 and weighed in at 111 and 110 grams respectively.

As might be expected male Goldfinches continue to outnumber females; the sex ratios in Britain and in Spain suggest that that a greater number of females migrate than do males, and also that females tend to winter further south (Newton 1972, Asensio 1986, Migration Atlas 2002). There does seem to be a steady changeover of Goldfinches through the garden at the moment, perhaps just locally wintering birds so it will be interesting to note when the proportion of females increases. No sign of Siskins yet.

A young female I caught today still had traces of buff, juvenile crown feathers - compare with the fully coloured male, the extent of red behind the eye and the depth of red below the bill.

Review: Petrels, Albatrosses & Storm-Petrels of North America

The weather outside is pretty foul, grey skies and freezing rain, a promise of snow and not much prospect of sensible birding or ringing for a day or two.

Fortunately Princeton University Press sent Another Bird Blog a copy of the newly published and much awaited Petrels, Albatrosses & Storm-Petrels of North America, A Photographic Guide by Steve N. G. Howell. So I spent the day sat next to a toasting radiator in front of the PC but all at sea with a brilliant book. Read on.

Steve N.G. Howell is a celebrated field ornithologist and writer, an international bird tour leader with WINGS and a research associate at Point Reyes Bird Observatory (PRBO) Conservation Science in California. His books include the Peterson Reference Guide to Moult in North American Birds and Hummingbirds of North America. These are impeccable credentials with which to pen this much needed book about the beautiful but often little known of all the world's birds which live their lives at sea, far from the sight of most people.

When Princeton University Press said they were sending me an early copy the main title didn’t give too much away apart from the fact that the volume might contain information and help towards identifying North American tubenoses. With the additional sub-title of “A Photographic Guide” l perhaps expected a handy, slim, field guide, something in a waterproof cover to take on a lengthy and inevitably wet and probably turbulent, pelagic birding trip.

Petrels, Albatrosses & Storm-Petrels of North America

In real life the book doesn’t resemble my expectation in any way, with the weighty tome having circa 500 hard covered pages with the contents more akin to a comprehensive and scholarly excavation into the mysteries of approximately 70 species of shearwaters, petrels and albatrosses occurring in North America. In the context of the book, North America is defined as waters within 370 km of land from Alaska and Canada, south to the Caribbean and Panama. The “approximately 70 species” hints at the ever changing taxonomic status and challenges to several groups of the tubenoses, taxonomic changes that where applicable are documented, explored and discussed in first-rate detail in the relevant species accounts.

The species accounts comprise headings and text in the form of Identification Summary, Taxonomy, Names, Status and Distribution, Moult, Field Identification, Habitat and Behaviour & Description, generally running into a handful of pages for each. This includes coloured maps which identify the species sea range, migration routes, moulting area and main patterns of occurrence, together with breeding sites for localised species. In the case of some difficult species e.g “Fea’s” Petrel the critical discussion on taxonomy and identification can stretch the highly readable and illuminating content to seven or more pages. Each species has a number of photographs to accompany the text, some of them quite superb, some inevitably less so.

As someone who indulges in a little land-based bird photography I am in admiration of many of the plates in this book, more so when I consider the challenges of taking pictures of a fast flying seabird from a moving boat in weather conditions conjured up by the word “pelagic”. I struggled to pick out just one or two examples to illustrate this feature of the book but settled on the plates below of Fea’s and Zino’s Petrels and then of European Storm Petrel. Note how the discussion of moult and identification is usefully continued into the photographic elements of the pages: the few plates shown here are far from unique in this respect.

Petrels, Albatrosses & Storm-Petrels of North America – European Storm Petrel

A feature I particularly like in each species accounts is the section headed “Names”, a paragraph or two which explains the historic, and oft-changed taxonomic origins of a species name, allowing the reader to reflect upon the enquiring spirit of those in history with an interest in these fascinating seabirds. Looking for an example to quote here I chanced upon the following, which includes reference to a British birder I once had the pleasure of meeting on the Isles of Scilly.

Grant’s (Band-rumped) Storm Petrel – Oceanodroma castro undescribed - means “ocean runner”, “castro” refers to “Roque de Castro” on Madeira, from which Edward Harcourt (1825-1891) described the first known taxon of Band-rumped Storm Petrel. The English name of the cryptic and as yet formally undescribed winter-breeding taxon commemorates British birder Peter Grant (1943-1990) who led the way in challenging identification forums.

To sum up, this is a fine book which covers a good number of the oceans’ wanderers, a volume which all birders and those interested in conservation should aspire to own, and in whichever continent they happen to live. Of the 70 or so species covered by Petrels, Albatrosses & Storm-Petrels of North America approximately one third qualify as vulnerable or endangered by human activity, an overall sad fact given emphasis by the author in devoting two pages to the subject, perhaps not enough, my only minor nit-picking of the whole book.

In the preface the author makes the point that there is still much to learn about Petrels, Albatrosses & Storm-Petrels – “If we know so little about birds as grand and iconic as albatrosses, imagine what else remains to be learned”. I’ll second that Steve, and any minute now I’m about to delve into your book again to do just that.

My advice to any birder out there is to order this book right now. At $45 or £30.95 it is a bargain from Princeton University Press. Even better at £24.04 from Amazon UK.

Killing Time?

When about midday the warming sun cleared the car windscreen and the roads of the overnight frost and ice, I took a trip Out Rawcliffe way. Last week I put a couple of Niger feeders out in readiness for any spring passage of finches so wanted to see how the feeders were performing. I say “any” spring passage because this winter has been totally different from the previous one. In the early part of 2011 and into March we were busy catching lots of Chaffinch, Brambling, Siskin and Lesser Redpoll, but in 2012 there are a lot less of those species, especially the latter three, so for instance I haven’t seen a Brambling since November.

There seemed to be birds around our spring and summer plantation today, mainly Chaffinch and Goldfinch, and although the Niger levels had hardly dropped I topped the feeders, set a couple of nets just in case and then took a wander through the still bare trees. After the frost a Woodcock was a certainty, and as I aimed for the clumps of winter bramble the question was not whether I would flush a Woodcock, but when it flew would it head towards the nets? It crashed off north, in the opposite direction to the desired one, but I got a good look as it twisted up and away.

I waited for the nets with in the background a Great-spotted Woodpecker drumming out his spring mating call, above the wood 2 Buzzards soaring, and in the distance 5 Roe Deer running across the stubble to the safety of a quiet copse. Click on the "xeno canto" arrow to hear the woodpecker.

Watching the plantation combined with a meander about clocked up 2 Kestrel, 18 Skylark, 8 Linnet, 15 Chaffinch, 12 Goldfinch, 3 Blackbird, 1 Lesser Redpoll and 12 Yellowhammer, but very few of them were interested in making a guest appearance on the field sheet; I caught just 5 birds, 2 Chaffinch, 1 Goldfinch, 1 Blackbird and 1 Great Tit. The shy Yellowhammers were coming in for the remains of the shooters wheat stock, providing me with an excuse to perhaps come back soon in the hope of connecting with one or two of the yellow buntings.

Well it may not have been the busiest of birding or ringing days, but it sure was enjoyable out in the sun and fresh, cold air.
