Flight Identification of European Passerines - A Review

A package arrived from Princeton Press, a book for review via Another Bird Blog - a newly released component of the highly successful WILDGuides series. The book? - Flight Identification of European Passerines and Select Landbirds, an Illustrated and Photographic Guide authored by Tomasz Cofta. 

Just the job for a locked down and now frozen in birder with time on their hands. 

Flight Identification of European Passerines and Select Landbirds - Princeton Press 
 
While the name Tomasz Cofta may be unfamiliar to many UK birders he is in fact one of the most experienced field ornithologists in Europe, having published more than a hundred papers on bird identification, featuring close to two thousand of his own artworks. In the past he has prepared thousands of meticulously detailed illustrations of birds and other wildlife, as featured in over sixty books, including The World's Rarest Birds, a book reviewed HERE on 11 April 2013. 

By any standards this new WILDGuide is a hefty book containing an initially daunting 850 colour illustrations and more than 2400 photographs. It didn't take long to realise, and as the title hints, this is a book aimed at a precise audience of birding purists, students of migration, professional ornithologists and vis-miggers rather than casual and/or weekend birders. 

To get the best from this book it is essential that readers study the Introductory pages from 7 through to 28 that itemise and explain the terminology used in the main body of the book. Pages 7 to 9 discuss size comparisons, while pages 10 to 13 tackle structure and shape, the latter including the sometimes overlooked profiles of birds in flight. 

Flight Identification of European Passerines and Select Landbirds - Princeton Press 

It would be a mistake if readers skipped these introductory pages, especially so for pages 10-13 which contain useful tips and reminders about body, wing, tail and changes in the shape of birds in flight. In the heat and drama of a rapid fly over or fly through with just one chance of an ID, how many times has a birder wished they had remembered to clock the X, Y or Z? I've been there too. 

For anyone just learning to vis-mig pages 16 to 26 become indispensable by explaining the variability of species' flight types and flight patterns that change according to a species' behaviour or circumstances. E.g. the long distance migration flight of most thrush species is completely different to their typical short distance flight. 

Flight Identification of European Passerines and Select Landbirds - Princeton Press 

The well thought out pages relating to calls at 27 to 28 also explain how the species' accounts link via the supplied QR code to a recording of the species being discussed. Better still is the author's promise that links will be updated as additional recordings become available. 

Each species account contains transliterations of flight calls, supported by sonograms of common and also less common species but where quite understandably, rarer species may be unavailable. For UK birders those rarer species might be seldom encountered during their birding lifetime so makes for some useful and day dreaming studies of species like White's Thrush or uncommon members of the Crossbill family. 

The meat of the book, the 237+ species accounts between pages 42 to 484 display a consistent format using the same terminology throughout. The layout of each page is mostly very similar in the number of illustrations used, illustrations that are digitally enhanced, via photographs, drawings and probably hand so as to retain the desired conformity of images. 

As the author explains, the remarkable number of species covered include a number of near passerines, “select landbirds” of the Title. The ecology of these species is similar to that of the passerines and they are often seen on migration at similar times of the day and/or year e.g. pigeons, doves and woodpeckers. 

Flight Identification of European Passerines and Select Landbirds - Princeton Press 

While the quality of both the coloured and the black & white illustrations is of good and sometimes exceptional quality, there are photographs of uncommon species that are far from perfect. As someone who uses a camera with varying degrees of success I understand that birds, and more so small birds in flight, can be almost impossible to capture, so even a less than perfect BIF is OK by me if it portrays the essential jizz. 

Flight Identification of European Passerines and Select Landbirds - Princeton Press 

After a day and or more with Flight Identification of European Passerines I cannot disagree with the publisher's statement that this guide is the “first of its kind.” Whereas in the past bird field guides have included limited information, sketches/photos and guidance to identify a species through flight, this book takes the subject matter to a new and state-of-the-art level. This book will help observers to nail their ID within the single most difficult part of birding. 

I struggle to think of a birder I know or know of who will not wish to buy this book. There is so much to enjoy within its pages, so much to learn and an awful lot to revisit for those who thrill at the sights and sounds of visible migration. Equally those bird watchers who seek to widen their knowledge and expertise will find more than enough to inspire them to head outdoors in these difficult times. As spring approaches the thought of a Pallid Swift overhead can excite any birder.  

Flight Identification of European Passerines and Select Landbirds - Princeton Press 

I thoroughly recommend to serious birders that they should buy this book. Tell Princeton you heard about it first on Another Bird Blog.

More Of the Same

After the latest visit to Gulf Lane Pilling/Cockerham today I carried out a quick audit of results to date. 

The DemOn program produced a table in seconds detailing the species and numbers caught at this single wintering plot since January 2016. The program itemised the number of “new”, N birds and the number of subsequent, “S” birds. N is self explanatory as “New”, the very first capture of an individual which is then fitted with a numbered ring. “S” refers to a bird that is caught on a subsequent occasion, one previously ringed by ourselves and later recaptured, or a bird ring elsewhere by another ringer and recaptured by ourselves. 

Linnets and others -2016 to 2021- via BTO DemOn

The 786 Linnet captures broken down into years equate to: 
2016 - 153 
2017 - 276 
2018 - 79 
2019 -113 
2020 - 138 
2021 - 27 to date 

The 11 subsequent captures relate to just 6 Linnets ringed at Gulf Lane and then recaptured at a later date. The remaining five individuals relate to exchanges between Gulf Lane and Northern Scotland and one between Gulf Lane and Walney Island. One of the birds was captured twice on North Ronaldsay, Orkney in the same spring. 



Linnet connections to Scotland
 
While it is interesting to attain “subsequent” records, our own birds, or better still a bird ringed elsewhere, the fact that we have so few as 11 “subsequent” Linnet records may surprise readers who follow our exploits. They will know that our winter ringing here is as regular and committed as the weather will allow and perhaps think that we catch the same birds many times over - we don't. 

Even during the weeks where more than one day is doable, we rarely capture the same bird twice. Catching “one of our own” is quite a cause for celebration. These results tell us that our winter Linnets are highly mobile, probably on an hourly, daily and possibly weekly basis and that the numbers we count are mere snapshots in time.

Our latest effort this morning of 5 January proved unproductive with just 2 new Linnets, an adult male and an adult female. The male proved to be the biggest of the winter so far with a wing length of 86mm, a figure close to the expected maximum for a male, a measurement that points to Scottish origin.

Gulf Lane - Pilling/Cockerham 

This morning's flock maxed out at 30, most of which were reluctant to feed in the target zone: we thought that some must be recent captures that have learnt the ropes of when to visit and occasions to avoid the largesse.  Roaming Linnet flocks are social units containing a diverse, variable membership of individuals and numbers at any given time, units that are able to remember regular feeding spots and to use them according to their own requirements.     

Other visitors today - 2 Reed Bunting, 1 Stonechat, 1 Song Thrush, 1 Robin, 1 Chaffinch, 1 Kestrel, 1 Sparrowhawk, 1 Barn Owl, 1 Little Egret. 

Today was a slightly disappointing result on a visit that may prove to be the last for some weeks if the nation is to be placed under lockdown again. 

We remain optimistic that during this latest lockdown small-scale bird ringing will continue to be seen as a necessary and essential activity. Bird ringing makes a vital contribution to society and to conservation while promoting mental and physical well-being to those taking part.

First Of 2021

We pencilled in Saturday for Project Linnet and the first ringing session of 2021. 

This proved a good decision because Friday arrived with black ice on roads where early morning rush hour drives are best avoided. The A588 via Pilling, Gulf Lane and Cockerham is one of the most dangerous roads in the UK. If the virus doesn't get you, the A588 Poulton le Fylde to Lancaster road probably will. 

The A588

After a good number of mild winters with just one or two days of frost there's a whole generation of people driving cars whose motoring skills are very poor in even normal conditions. The first days of ice and snow finds them driving fairground dodgems at often breakneck speeds without the slightest concern for their own safety or that of others. 

By Friday afternoon and after a little sunshine, the ice had gone. A check of the Gulf Lane Linnets together with a supplementary seed drop had seen 40 Linnets, 3 Stock Dove, 1 Robin, 1 Song Thrush, 1 Kestrel and 1 Reed Bunting. The rapidly thawing fields alongside Murder Mile held hundreds each of Lapwings, Golden Plover, Curlew, Redshank, Black-headed Gull and Common Gull. 

Lapwing

Golden Plover

Curlew
 
Andy and I arrived this morning to another thick frost but safe and sound at 0815.  At minus 4° degrees there's no point hanging around so we set the whoosh net to “ready” and then retreated to the car for a cup of warming coffee and the first Linnets. 

Linnets
 
Linnets came quite quickly and we had a small catch within 15 minutes. We continued in this vein until midday by which time we had caught 25 Linnets, our best of the winter so far. 

It was very noticeable today that we had zero recaptures from the last two weeks. That rather spoilt the idea that the Linnets we saw today were the self same ones of recent days and weeks. In fact what we are seeing is groups and flocks of Linnets on a round robin of local feeding spots that may be a mile or two apart.  It's the old story of the neighbour who tells a birder of the same Robin that comes to their garden every day, every year.

Also obvious today was an influx of adult Linnets including some rather large males. Linnets caught - 11 adult males, 3 adult females, 7 first winter males and 4 first winter females. With snow and frost around here we can be certain that there is a lot of cold weather in the High Pennines and in Scotland with temperatures low enough  to set Linnets on flight paths to relative warmth and guaranteed food.

Other birds seen but not caught - 2 Reed Bunting, 1 Robin, 1 Snipe, 1 Blackbird, 2 Barn Owl. 

Back soon. Happy New Year and Happy Birding everyone.  Let us hope that 2021 will be a major improvement on 2020.

Nailed On?

On Wednesday morning I met up with Andy at 0815 to a cold, frosty start of minus 1.5° degrees – not the best conditions for messing about with metal poles, pegs and cords. We had coffee, five layers, the will to succeed, and as usual, lots of theories. Ringers will know exactly what I mean.

A Frosty Start 
 
Setting Up

The catch seemed as they say, pretty much “nailed on.” I’d been topping up the Linnets’ supplementary winter diet for days without an opportune day for catching purposes. Topping up trips of 27 December and 29 December had given counts of 50+ and 70+ Linnets respectively. Even better, recent cold mornings had witnessed the Linnets hunger by their wasting no time to drop onto the niger, millet and rape seed mix. Gangs of 20 to 40 birds in the immediate catching area had been regular, if as flighty as ever. Timing pulls of the whoosh net would be crucial if we wanted a good sized catch today. 

However, the schemes of mice and men rarely if ever turn out exactly as planned. The Linnets were less in numbers, a max count of 35 all morning and they seemed reluctant to stop in the catching zone. 

Eventually we caught a couple of times and finished up with just 8 new ones - 3 first winter males, 2 first winter females, 2 adult males and 1 adult female. 

Linnet

Although the catch was poor a series of such numbers and a winter total in excess of 100 Linnets will help our ideas about the proportion of Scottish Linnets in this winter’s birds. Although for now we have rejected the concept of their being a proven Scottish sub-species, Linaria cannabina autochthona (in litt) previous winters have shown that a proportion of the Linnets we catch are definitely darker, bigger, and longer-winged than their archetypal English cousins. We are sure that such variation is clinal rather than species driven. 

In between our ringing we noted other birds as 1 Wren, 1 Barn Owl, 1 Kestrel, 1 Robin, 1 Reed Bunting, 2 Stonechat and 2 Little Egret. 

Barn Owl
 
Meanwhile back at home Sue had been busy going through the Christmas cards in readiness for recycling. I had plans for one card in particular. 

A Blogger pal, Rain Frances who lives in New Brunswick, Canadian Maritimes, had posted us a card of one of her original and signed pen and graphite sketches. This now sits framed on my office window sill. 

Lucille Ball by Rain Frances

For those of a certain age, the portrait is immediately recognisable as Lucille Ball in the 1952 B&W episode of Lucy & The Chocolate Factory. 

Rain is a talented amateur artist with plans to sell her work soon through an Internet market place like Etsy.  You can visit Rain's blog and admire her creativity at  Rain Frances.

Here's wishing Rain and all my blogging pals a Happy and Prosperous New Year.

See you soon.

Last Minute Win

Wednesday evening. There looked to be a window of weather for the morning of Christmas Eve. All the forecasts promised a biting northerly wind with a frost but this would probably be our last ringing session for 2020 so one not to miss. 

There was a film of ice on the windscreen that soon cleared and by 0830 I was at Gulf Lane to meet Andy where we hoped to catch a Linnet or two. Recent numbers of Linnets had been poor but as they say “Hope springs eternal” and we needed few Linnets to bump up the year’s total for Project Linnet 2020/2021. 

We set the whoosh net, put out fresh seed and waited with a hot coffee to warm our by now icy fingers.  

Ready To Go

The Linnet flock numbered 40/50 at maximum so we were quite pleased with our catch of 10 – 5 first winter females, 4 first winter males and 1 adult male.

Other birds seen during our stay- 2,000+ Pink-footed Geese, 2 Stonechat, 1 Robin, 1 Chaffinch, 1 Wren, 1 Reed Bunting.

Now you must excuse me. There’s a pile of spuds, carrots and parsnips to fettle and a glass of ouzo waiting for the kitchen volunteer.

See you soon fellow blogger and birders. Have a great Christmas. See you soon.

No Go Blow

It’s Saturday morning and there’s something required for the weekend – blog posting. It’s been one of those weeks again with everlasting cycles of wind, rain and blow after blow that makes for difficult, unproductive birding and impossible ringing. 

We tried to get to the 450 Linnets at Glasson Dock near Conder Green but the niggling southerly winds with blowy nets meant the safety first of another no-go.

After yet another early doors I returned home and surfing online. I came across a story on Bird Guides news about a gull that demanded my attention. There at the head of the news item was one of my own images taken in Menorca in 2016 – an Audouin’s Gull Ichthyaetus audouinii. 

Audouin's Gull - https://www.birdguides.com/

The Audouin’s is a large gull restricted to the Mediterranean Sea and the Iberian Peninsula. The genus name is from Ancient Greek ikhthus, "fish", and aetos, "eagle", and the specific audouinii and the English name are after the French naturalist Jean Victoire Audouin.

For those who struggle with French pronunciation, the “Oddwin’s”, is one of the rarest gulls on the planet but pretty common in Menorca. Here some individuals have adopted the habit of taking food from the island’s visitors. The givers are mostly Brits banned now from feeding gulls at home for fear of being fined heavily by jobsworths and the Thought Police. 

I included more of my own archived photos of this most delightful of gulls, pictures taken in Menorca where the gull breeds on tiny offshore islands. Getting a clear image of that highly distinctive red, black and orange coloured bill depends upon good light and the pose a bird adopts. 

Audouin's Gull
 

“A territorial pair of Audouin's Gulls was observed on the Atlantic coast of France during summer 2020, and although breeding could not be confirmed, hopes are high that the birds will return in 2021. 

On 4 May 2020, Matthias Grandpierre was conducting a survey in the dunes at Banc d'Arguin Nature Reserve in Gironde department, south-west France, when his attention was drawn to an unusual gull call. It quickly became apparent that the vocalisations were coming from an Audouin's Gull, which was behaving much in the same manner as the other breeding gull species in the vicinity. 

At the beginning of June, during a boat count, Matthias noticed an Audouin's Gull on the beach, close to the colony. It was wearing a coloured ring engraved with an alpahnumeric code. It transpired that this bird had been ringed as a chick at the nest in Castellón de la Plana, north of Valencia, Spain, on 11 June 2018. "

Audouin's Gull

Audouin's Gull

"Throughout the first half of June, while conducting further surveys of the gull colony, an Audouin's Gull was always seen defending its territory in flight. Over the same period, observations from a boat repeatedly noted the ringed Audouin's perched in the same spot on the beach, although whether one or two birds were involved remained a mystery. 

Then, on 16 June, two Audouin's Gulls were observed side by side – one ringed and the other unringed. The birds were engaging in nuptial behaviour and vocalising regularly. Due to the colony always taking flight on approach, and with many gulls swirling overhead, finding a possible nest was a difficult challenge and ultimately failed. 

Although the presence of young was not confirmed, this is the first case of potential breeding of this species on the Atlantic coast of France, and the most northerly on record. "

Audouin's Gull

"The closest Atlantic-coast colony to Banc d'Arguin is in southern Portugal, where 2,663 pairs bred in 2019. This increased appears to correspond closely to the decline and abandonment of some Spanish colonies, which suffered a 31% decline between 2013 and 2017. 

In France, Audouin's Gull breeds only on Corsica, where 40-60 pairs have nested in the Ajaccio and Aspretto area since 2012.” 

With the holiday week coming up days out birding will be limited but for now Tuesday next is pencilled in for a spot of ringing.

Fingers crossed  - again.

Sittin’ On The Dock

Between rain showers I’ve regularly checked out the Linnets at Gulf Lane in the hope of a ringing session. The visits gave a series of unpredictable and disappointing counts between zero and 50. These are numbers that inspire little confidence in a catch of Linnets, a species that is in any case nervous, jittery, flighty and difficult to catch. 

At least one Stonechat, the male, has hung around at Gulf Lane; visible most days at the top of the bramble that lines the ditch, but I now see the female less frequently. A couple of days ago the male caught an enormous caterpillar as below. Into the afternoon light I could not get the photo I wanted but the green caterpillar was quite interesting in being so long and meaty. 

Perhaps a Winter Moth Operophtera brumata? Are there any lepidopterists out there? 

Stonechat

On Thursday and because of the lack of birds at Cockerham Andy and I decided to have a go at the Linnet flock that’s been building close to the River Lune marshes at Glasson Dock, about 7 miles from Gulf Lane. In recent days the flock at Glasson has numbered around 200 birds so I squared it with Stewart the land owner for a visit and met Andy on site at 0800. 

River Lune marshes, Lancashire

The wind was a little fresh and from the “wrong” direction but we caught 8 first winter Linnets, 5 males and 3 females. Following our couple of hours on site rather than the more usual spot counts we now estimated the number of Linnets at 400+. 


 
So now we await a morning of wind from the north and sheltered nets or that real rarity, a frosty morning of zero wind. 

Stay tuned for more news soon from Glasson Dock of Morecambe Bay.

A Touch Of Frost

Most unusual - there was hint of the white stuff this morning when Andy and I met up at Gulf Lane at 0830. The temperature gauge read 1° but it felt warmer in the already rising sun. 

Three days earlier we’d cut a square from the now defunct seed crop in preparation for a first catch of Project Linnet 2020/2021. We left a mix of rape seed and millet on the bare earth and crossed our fingers. The autumn had seen very few Linnets so far when a typical late November flock here should number 200/300 individuals. When we returned to our cars ready to leave only then did we note a flock of 40 Linnets in the tree tops of the nearby farm. That gave us hope for the days and weeks ahead, more especially for this Tuesday and the promise of a sunny morning. 

Prepping The Square
 
And then on Sunday I checked if the seed had been found. Indeed it had, not by Linnets but by the predictable Wren and a party of 8 Stock Doves. There was the unexpected bonus of a pair of Stonechats but yet another dismal grey morning when a tiny Stonechat half way across a field presented a difficult target for a camera. 

Stonechat

Stonechat

We had a similar count of Linnets this morning with 40 or more doing their usual flypasts without committing to landing in the target area. We caught the female Stonechat, but not the more wary male. We aged the female in the hand as a first autumn/winter. We had nothing else but felt that our effort of a few days earlier paid dividends in preparing the ground for better luck next time when Linnet numbers increase. 

Stonechat- first winter female
 
Very little is known about the Stonechats which appear in this part of Lancashire during late autumn and early winter. Sometimes they stay to winter, other times not, depending upon the severity of January to March. It is likely that they are representatives of the partially migratory cohort of Scottish and Northern English Stonechats that breed in the upland fells but move to warmer climes at signs of cold weather. 

It is almost certain that they are different individuals from the small number of Stonechats that breeds at our coastal localities in the summer months. 

Stonechat
 
Other birds seen during three hours of watching Linnets fly around but not in - a single Goldfinch, 2 Buzzard, 2 Reed Bunting, 2 Wren,2 Chaffinch, and the pair of Stonechats. 

Many thousands of geese flew off the marsh and headed inland this morning. A local shooter with a regular handle on these things opined that the first calm and frosty night for weeks had seen an influx of ‘pinks’ from the Scottish Solway, perhaps as many as 15/18,000. 

Pink-footed Geese

Reed Bunting

Chaffinch

And now those Linnets need checking on a regular basis, as does the seed that we left behind. 

Let me know how many Linnets you count and also whether the Stonechats stick around.
