Testing Times

Andy and I arranged to meet up at Gulf Lane this morning to test our latest theory about Linnets - we catch better on frosty mornings? 

There was a ground frost and a temperature of -1° at 0800. We had been here on Saturday 4th January and despite a spot count of 400 Linnets we caught a big fat zero, not a single one; the Linnets just weren't interested, this in contrast to 2nd January when we had a catch of twenty-seven. The difference between the two days was - on January 2nd there’s been an overnight frost followed by an icy morning of -2.5°. In total contrast the morning of Saturday 4th January was much warmer at 7°C. My post, Another Bird Blog of 2nd January - “Twenty seven was our best catch of the winter, probably helped by the frosty start and the Linnets’ keenness to eat”. 

These are wintering Linnets only, ones which and dependent upon the coming weather, may be back on their way North as early as March. That leaves us just eight or ten weeks to reach our target of 200 new Linnets for the winter period. Another 100 to go. 

We set the nets followed by another bucket of millet and rape seed then waited for the Linnet’s arrival. Although the Linnets arrived in good numbers – up to 300, we caught just four. All four were females today. So although it’s back to the drawing board for our next theory, we do not give up so easily and remain convinced that catches will improve.

“Ringing has been an important research tool for the conservation biologist over the last 100 years. Effective conservation of wild bird populations requires understanding of bird ecology, the factors driving population change, and evidence that proposed conservation measures can be effective. Bird-ringing studies can provide a wide range of data types to aid and inform this process, and in many cases these data are not available without the capture and marking of individual birds.” 

The above is a summary of a paper from Ringing and Migration “The value of ringing for bird conservation”, written in 2009 by Guy Q.A. Anderson and Rhys E. Green. 

The full paper, too lengthy to post here, includes sections on:

A Birding Glossary

Here I am on a miserable Sunday afternoon, mizzly, dank and grey with nothing on the telly, just the usual BBC propaganda, Sly News or tired old films. 

I got to thinking about the birding terminology, names and acronyms used in the world of birds here in the UK. Birding and birdwatching is a pastime that has evolved its own lifestyle, culture and even language. It is a way of life often mocked and misunderstood by those yet to experience the joys of ticking a mega bird or to suffer the anguish of a dick’s pip dip. 

So anyone looking to enter the world of birds may find the information below a useful Aide Memoir. Hopefully by studying and memorising some of the terminology it will allow them to slip seamlessly into the world of birds at a level appropriate to their experience – or not, as the case may be! Using the right jargon can be a passport to acceptance by the birding community, but getting it even slightly wrong can lead to being “sussed”, side-lined, and in extreme cases, quickly ostracised. 

For now we’ll skip the major terms of Birder, Bird Watcher, Lister, Bird Chaser, Twitcher, Ornithologist, Robin Stroker, and Rasberry. These are labels which need a whole post and more in which to explore the perils and pitfalls of acquiring such a tag for oneself or to apply to others.

I tried to put the list in some sort of logical order but gave up and opted for random. Where appropriate there are warnings as to when, where and why it may not be wise to use a particular expression or shorthand. Some are thought to be derogatory if said to another birder’s face, the bird itself, or made in reference to a hallowed bird organisation. The list is not exhaustive and I am sure readers can add their own examples.  
Let’s start with some simple almost self-explanatory ones for LBJs - Little Brown Jobs. 

Acros- Acrocephalus warblers e.g. Reed and Sedge Warbler etc. Also, reedy, sedgie. 
Hippos- Hippolais warblers. e.g. Icterine Warbler and Booted Warbler etc. 
Phylloscs - Phylloscopus warblers. e.g. Chiffchaff and Willow Warbler etc. 
Gropper or PG Tips - Locustella warblers - Grasshopper Warbler and Pallas’s Gropper respectively.
Mipit - Meadow Pipit
Tripit - Tree Pipit
Trepi – Tree Pipit - reserved for bird ringers only. Bird Ringers have exclusive codes which set them apart from mere birders. 
Wipit - Water Pipit 
Rokit - Rock Pipit 
OBP- Olive-backed Pipit 
Dick’s Pip or Dick’s - Richard’s Pipit 
RBF - Red-breasted Flycatcher 
Spotfly or Spofl - Spotted Flycatcher
Sibe - a vagrant of Siberian origin 
Yank - a vagrant (bird) of usually North American origin 
Pink Stink – An adult Rose-coloured Starling. A tip – Birders are wholly uncomplimentary about the starling family, unless it’s a Golden O – Golden Oriole.
Fawn Yawn – a juvenile or first winter Pink Stink. Think about it, or see “Collins” below. 
Junk Bird - Slightly controversial. A bird so common as to be worthless on a list other than a life list. For example - House Sparrow, Wren, Dunnock or Blue Tit. Or formerly, a Greenfinch.
Gringo - a Greenfinch. 

Beware of assigning an LBJ to the wrong family tree - an embarrassing mistake that breaks a birding social convention of “knowing ones Collins”. Collins Field Guide THE Most Complete Field Guide To The Birds Of Britain And Europe.

"Gropper"

"Spofl"

Now for a few members of the wading family: 

Barwit - Bar-tailed Godwit 
Blackwit - Black-tailed Godwit 
Hudwit - Hudsonian Godwit 
Curly Wurly - Curlew 
Peeps - reserved for North Americans on a UK birding trip - small Calidris waders that real birders call stints- e.g. Little Stint or Curlew Sandpiper 
Oyk - Oystercatcher. As distinct from an Oik who blocks the view during a twitch. 

"Curly-Wurly"

And Seabirds: 

Manxie - Not a tailless cat but a Manx Shearwater 
Bonxie – Great Skua 
Commic Tern - Common/ Arctic Terns that are too distant to differentiate safely enough between the two. Beware of using this label and thus admitting to incompetence whilst in the company of a birder higher up the echelons of the birding world. 
As above - Corvid for use when unsure whether the bird is a Rook, Carrion Crow or Raven. N.B. Can be more acceptable than Commic Tern. 

Manxie

Others:

Plastic - a bird which is likely to have escaped from captivity. Use with care as a “plastic” may by higher authority later become a “tick”, in which case can be retrospectively claimed as an “armchair tick”. 
Yuck Duck – similar to Plastic. A hybrid but often wild duck, mostly the result of a union between a Mallard and a farmyard duck. Take care not to spend time trying to ID such birds as they will never qualify as a tick. Furthermore, the observers' credentials as as serious birder will be seriously damaged.

In Part Two of Birding Glossary we explore other terms, some of which often induce controversy and even conflict into the genteel world of bird watching. Words like suppression, stringer, dude, lumper and splitter. 

Be there or be a dipper. But best not to be gripped off.

All Fired Up…....

…... and somewhere to go. After the news on New Year’s Eve that Linnet AYD5167 had been ringed on North Ronaldsay Orkney it didn’t need much persuasion to get out ringing again. Even better, the forecast promised near zero wind and a bright morning that would get hungry Linnets moving around. 

I met Andy at Gulf Lane to -2.5°C and where we hoped that lightning might strike twice by way of another ringed bird from the Highlands or the Islands. 

Gulf Lane - Pilling/Cockerham  - 2nd January 2019

Gulf Lane - Pilling/Cockerham 2nd January 2019

We set up the ringing station in Andy’s hatchback and made a mental note that now into 2019 all birds become a calendar year older and ageing codes change overnight; first year 3s become 5s and adult 4s magic into 6s.

Just think, if we could do that with friends and relatives we could post every birthday card on the First of January and never again worry about being in the doghouse by missing that vital one.

Oops, the first Linnet went onto the field sheet as a “3”, but we soon got into the swing of it and kicked off the ringing year with 27 new Linnets and zero recaptures. Twenty seven was our best catch of the winter, probably helped by the frosty start and the Linnets’ keenness to eat, not least on the bucket of fresh, dry millet and rape seed we deposited on the frozen ground.

Our best spot count this morning was of a maximum 300 Linnets, the only other small birds in the immediate area being Wren and Dunnock.


Linnet - first winter male Age "5".

The catch this morning comprised 12 first winter male, 8 adult male, 6 first winter female and 1 adult female; once again, a preponderance of males.

Great Result

Wow. We had had a great result from the Linnet mentioned on here a day or two ago. 

As suspected, ring number AYD5167 that Andy and I caught at Gulf Lane on 24th December had been ringed in Scotland. Better still, the Linnet location on 8th September 2018 was the Scottish island of North Ronaldsay, Orkney some 605 km due north of Gulf Lane. 

Wiki - “The main purpose of the island's bird observatory, established in 1987, is to conduct long-term monitoring of bird populations and migration. North Ronaldsay is well known as one of the best birdwatching sites in the country during the spring and autumn migration periods.”

Given the location of North Ronaldsay there is a good chance that AYD5167 was passing through and that its original location and birth place in the summer months was Shetland, or even Norway. We cannot know for certain where it began the long journey south, however this latest information is now the third link between the wintering Linnets of Gulf Lane and the far North of Scotland. 

The Orkney Islands UK

My one visit to North Ronaldsay was more years ago than I care to remember, but I do recall, quote - “the quantity and variety of birds that can be seen at these times is often spectacular.” It was too and I recall catching Long-eared Owls, Yellow-browed Warblers, Waxwings, hundreds of Scandinavian Blackbirds, and a real rarity, a single Pine Bunting.

There was even a Linnet or two.

Stay tuned. Wednesday is looking good for more birding and ringing.

Linnet Recap

Andy and I met up again on Thursday morning for another crack at the Linnets. 

The Linnets didn't want to play ball and it could be that many or most of the 300 present were the same as on 24th December and would not be captured twice. So we caught just 4 Linnets but once again all four were quite big males at wing length 84, 83, 83 and 82 mm.

One in particular was very dark on the cap, the head in general and noticeably on the nape. We thought it more than likely this was a good example of the Scottish race of Linnet Linaria cannabina autochthona, and that coupled with a catch of similar examples on 24th December, recent days have seen an influx of Linnets from the far north of England and from Scotland.

This is probably the last ringing session here in 2018 but we will return as soon as possible in 2019 to continue with our work. 

For the benefit of readers yet to learn of this project.

Andy Dixon and I began Project Linnet in the autumn of 2016 to investigate wintering Linnets using a site at Gulf Lane, Lancashire; here the two parishes of Pilling and Cockerham meet alongside the A588 at Wrampool Bridge. Just 100 yards across sheep pasture to the north is a 10 mile sea bund that links the town of Knott End in the West to the parish of Cockerham in the East. The bund/wall protects farmland and villages from the infamous tidal surges of the area, the southernmost extremity of Morecambe Bay Site of Special Scientific Importance (SSSI). 

Gulf Lane - Pilling/Cockerham 

The background to our mission is as follows. In the Fylde, Lancashire the Linnet’s demise over a number of years is part and parcel of the species’ national decline that has resulted in its current UK status as a fast disappearing farmland bird. This part of coastal Lancashire has not been immune to these environmental changes and as a highly agricultural area reflects the typical downward trend for the UK Linnet population. 

The Linnet is resident throughout the year in this part of Fylde, Lancashire. As a partial migrant it is here in spring, summer and autumn but numbers usually increase during October/November/December and into March/April according to the severity of winter. 

My own observations and experience from the last 40 years, more so since the Linnets gradual decline that began some 20 odd years ago, suggested that the regular winter influx of Linnets has helped to mask a substantial loss in the species’ breeding population in the wider area of the Fylde.  

A look at local sources of both digital and printed information painted a very sketchy picture of the Linnet’s status, with nothing to suggest that our winter Linnets were other than local birds choosing to spend their winter close to where they breed.  Other than random and piecemeal counts from the  area, there was little or no work, past, present or proposed to establish the species’ overall breeding and migratory status, even though the partial migratory habits of the Linnet is well documented elsewhere. 

So when a chance to investigate a wintering population of Linnets presented itself the two of us decided to use the opportunity to catch and ring this previously neglected but now priority species. Our project at least gives us a fighting chance to find out where winter Linnets originate from, and where they go to the following spring. In the process we might prove the conservation value of argri-environment schemes that provide winter feed to a number of bird species including the Red-listed Linnet. 

Our ringing site is a triangular plot of farmland, planted each year with a mix of cover crop that yields bird seed during the autumn and winter. There is no cover or hedgerow to protect the site from this often windswept part of Lancashire with the nearest habitation two small farms some 100 yards away; hence we are very dependent upon fine weather in using mist nets. Our project is a labour of love that requires both dedication and persistence in the face of the often poor weather and the uncertain nature of Linnets and their feeding habits; e.g. Thursday 27th December. 

Including Thursday we have 508 captures - 363 juvenile or first summer/autumn, (212 male, 148 female and 3 not aged), 63 second years (36 male and 27 female) and 80 adults (52 male and 28 female). 

Same site recaptures have been few and far between, a fact that tells us the daily, weekly and monthly turnover of Linnets on site is huge. From the 508 captures there are just two individuals caught on two occasions each. These two at least display a degree of loyalty to the same winter site: 

S348543 caught on 03/10/2016 and 03/12/16 
S800285 caught on 02/11/2017 and 09/03/2018. 

In contrast to the two individuals above, other records show the species’ migratory status. 

There are 2 Linnets ringed at Gulf Lane and recaptured elsewhere (Lochinver, Scotland and Barrow, Cumbria), There are 2 Linnet ringed elsewhere and recaptured at Gulf Lane - Shetlands, plus one outstanding - AYD5167.

Mainly Men

With so much wind and rain in recent weeks there’s been little chance of getting to Gulf Lane. This is highly frustrating, even embarrassing, when a recent count realised 280+ Linnets on site compared to our miserly catch of just 30 birds for the whole of this autumn/winter. 

Monday promised better things so I met up with Andy at 0815 to a clear if cold and frosty start of Minus 2°C. We were joined today by Bryan. 

Linnets appeared soon after dawn and continued to arrive in small parties until at the peak of activity at about 10 am when we estimated 300 birds. 

Our catch was much better today with 20 Linnets. The catch included a first winter male already bearing a ring (AYD5167) but not one of our own. We hope that when details of its original ringing emerge it will prove to be another bird from Scotland, especially since its biometrics came in at 83 mm wing length and a weight of 20.3 gms. Three of the other males today had wing lengths of 86, 84, and 84 mms respectively. 

The 20 Linnets caught comprised 11 first winter males, 5 adult males, 3 first winter females and 1 adult female - so this was something of male morning. Pure chance or perhaps other factors; who’s to know? Ideas on a postcard to …… 

Below is AYD5167, a first winter male. We named him Jimmy and sent him on his way. 

Linnet AYD5167 

Today's Linnets 

The flock today appeared to be wholly Linnets apart from one or two Tree Sparrows. Otherwise we noted several thousand Pink-footed Geese leaving the nearby marsh. We saw 3 Buzzards in the vicinity of our plot but all in flight. 

I believe there’s something planned for tomorrow; someone just mentioned peeling spuds, carrots and parsnips. So that's me signing off for a few days. Hopefully back on Thursday.

A Tale Of Two Fieldfares

We don’t ring too many Fieldfares but on Friday came news of a Fieldfare that Andy and I ringed up at Oakenclough, Lancashire on the morning of 1st November 2017.

“The morning followed the same pattern as the last two occasions here. There was a dawn arrival of thrushes from the south east and quickly leaving in a westerly direction that lasted in all about 40 minutes. This was followed once again by a slow morning of odds and ends of thrushes, a lack of finches and just 26 birds ringed. Totals captured: 9 Redwing, 3 Fieldfare, 4 Goldcrest, 3 Goldfinch, 3 Blue Tit, 2 Coal Tit, 1 Blackbird, 1 Chaffinch. In all we counted approximately 80 Redwings, 40 Fieldfares and 5/6 Blackbirds.” 

The first winter male Fieldfare was given ring number LC94559. We released it so it could continue its onward migration south and over the English Channel, and thence to the Southern Europe. 

Fieldfare 

Then on Friday came details of the same bird’s death 406 days later. It was found “Freshly dead - unidentified thrush within about a week of 12 December 2018 – Hunted” at Val d'Ornain, Meuse, France some 766 km from Oakenclough. 

Fieldfare - Oakenclough to Meuse, France 

So our Fieldfare probably spent its first winter in the same region of France, returned to breed in Scandinavia during the summer of 2018, and was then killed during early winter of 2018. 

“Fieldfares are hunted and trapped in large numbers over much of their continental autumn and winter range. 58% of all deaths of known cause were deliberately taken by man. The principal countries involved have been France and Italy.” BTO Migration Atlas. 

It’s a sad end for a very beautiful bird. 

Now here’s news of a different Fieldfare that flew in the wrong direction and ended up in British Columbia. 

From the The Vancouver Sun 19th December 2018. 

SALMON ARM - A wayward bird seems to have taken a fancy to Salmon Arm. 

A Fieldfare, spotted only once before in B.C., was still foraging in the company of American Robins on Tuesday, three days after being sighted in the town’s annual Christmas bird count. 

“He’s still around, which is quite remarkable,” said Roger Beardmore, who first photographed the Fieldfare. 

Fieldfare - Roger Beardmore 

“It’s good that he’s staying put, because it’s given a lot more people the chance to see him,” Beardmore said. 

The bird was viewed by dozens of people on Tuesday near the corner of Krick Road and Kernaghan Road. 

So, how rare is a Fieldfare? Between 1991 and 2015, only one Fieldfare was reported in the United States, according to eBird. 

The bird breeds in the eastern part of Russia, but migrates toward Western Europe. Speculation among birders is the Salmon Arm Fieldfare got blown off course by a big storm and found his way down the Alaska-B.C. coast. A Fieldfare was spotted in B.C. only once before, in December 2003, near Pitt Meadows. 

Beardmore and his wife Ann were participating in the Christmas bird count when they spotted a bird they didn't recognize feeding on mountain ash berries. An amateur photographer, Beardmore used a high-quality long lens to get excellent pictures of the bird, which was later confirmed to be a Fieldfare.

“Although he’s a long way from home, he seems to be in excellent health,” Beardmore said.
