Missing The Grey

At last a slightly better morning with a hint of sunshine. There was no rain but too breezy to plan a ringing session, so it was birding for me. 

With these 0800 late starts there’s always traffic about. Near Hambleton I spotted a Barn Owl sat on the roadside fence. But on a single track road where “white van man” was closing fast in the rear view mirror there was no option but to sail past the owl. I stopped at a pull off point 50 yards away just in time to see the owl fly over the tall hedge and off towards its daytime roost in a broken down old building. I consoled myself with the thought that the owl was so close to the road that had I stopped it would have flown off anyway. It’s the same location where I saw Barn Owls a number of times in the summer and autumn.

I stopped at Pilling to check on the Linnets where if the wind speed will drop we hope for a ringing session before weekend. There are still plenty of Linnets to go at with 200/240 flying around the plot this morning. Nearby a Buzzard sat atop a pole while taking a close interest in goings on below. 

Buzzard

Near the farm at the head of the lane there was a Kestrel, one of four I saw this morning at Stalmine, Pilling (2), and then Cockerham. I’m hoping that these possible incomers can replace the Kestrels we appeared to lose this year. Kestrels are partially migratory and dispersive whereby young ones move from their birth areas and in their second and subsequent years may breed many miles from their initial home. 

Kestrel

I stopped in the gateway of Braides Farm and scanned the distant flood and the many birds thereon. It’s worth spending an hour more here as there is a constant movement of wildfowl and waders arriving, leaving or simply flying around after being spooked for a not always obvious reason. This morning : 500+ Lapwing, 190 Curlew, 80 Black-tailed Godwit, 60 Redshank, 75 Teal, 24 Wigeon and 22 Shoveler. 

I spoke to a wildfowler coming off the marsh about the comings and goings of the geese and wildfowl. Like many wildfowlers he was very knowledgeable and he told me of his sighting of a Grey Phalarope as recently as 8th December. I had no reason to doubt his claim, especially when he described how he watched the bird from 10ft away. 

The Grey Phalarope is a truly pelagic species and it spends up to 11 months of the year at sea, only coming to land to nest. The migration route of Canadian and Greenland birds takes them past Britain and Ireland, but normally well out to sea. Here in North West England it is a rare passage migrant, usually after Atlantic depressions that bring strong westerly or north-westerly winds towards the western side of Britain. There are approximately 500 records of this species in the UK each year and when they turn up, they are invariably highly approachable.

I made my way to Conder Green where my beginner’s mistake of not keeping an eye on recent tide levels meant that the creeks were full of water from the rising tide of the River Lune. 

Conder Green at high tide

So a somewhat different and reduced species count for here of 230 Teal, 45 Wigeon, 16 Snipe, 22 Redshank, 1 Spotted Redshank, 4 Little Grebe, 2 Shelduck. Fifteen Whooper Swans flew to the outer marsh and 5 Fieldfare were feeding in the near hedgerow. 

Around the lanes of Jeremy and Moss I noted a hundred or more Fieldfares feeding in the wet fields and also noted that many hawthorns are quickly losing their berry crop. 

Fieldfare

 

It’s about this time of year that Fieldfares turn from feeding on hedgerow berries to searching fields for earthworms. Or they may even appear in urban or suburban gardens, as one did this week in my own garden where it found the laden crab apple tree planted some 10 years ago and which until now has been mostly neglected by garden birds. 

Look in again soon. There might be pictures of that Fieldfare and if Andy I get to Pilling, a Linnet or two.

Harrier News

There’s recent news (November 2016) of the ongoing debate around the similarities and differences between the European Hen Harrier and the North American Harrier. Scientists have confirmed that the Eurasian Hen Harrier and the American Northern Harrier are in fact two distinct species. 

The study, published as the cover article in BioMed Central's Avian Research, led by the Earlham Institute and the Museum of Vertebrate Zoology at the University of California, explores the phylogenetic relationship between two forms of Harriers (Circus cyaneus); the Eurasian Hen Harrier (C. c. cyaneus) and the American Northern Harrier (C. c. hudsonius) to distinguish their ancestry and evolution. Already accepted as different species by the British Ornithologists' Union, the American Ornithologists' Union and other avian taxonomic committees are yet to classify the bird of prey as separate species.

Hen Harrier - Richard Crossley (The Crossley ID Guide Britain and Ireland)

As the most intensely persecuted bird of prey in the UK, Hen Harriers are under particular threat from being caught up in the crossfire of grouse hunts in upland moors where they feed on Red Grouse. After the number of breeding birds increased after the Second World War, the bird of prey is in trouble again. Ongoing illegal hunting and habitat disruption is forcing the species to edge of extinction in England. To understand the Hen Harrier species' genetic make-up is of extreme importance to its future and will help aid the national conservation efforts such as the RSPB's Hen Harrier LIFE project. 

Lead-author and conservation genomics expert Dr Graham Etherington in the Di Palma Group at EI, said: "Molecular phylogenetics was applied to the Hen Harriers and the Northern Harriers to see if genetics could shed some light on whether the accepted morphological nuances between the species indeed represent a genuine distinction. From a conservation point, the work shows the European Hen Harrier is not the same as the American Northern Harrier and should receive appropriate recognition and protection. 

“Before the advent of sequencing technology, species were categorised by shared and divergent morphological features. However, new technology allows us to quantify the amount of genetic change between populations and identify divergent lineages." 

In his research, Dr Etherington collected tissue samples from museums around the world. Using both DNA sequencing and morphology, along with differences in plumage, breeding biology, vocalisation, habitat, distribution, dispersal and migration it was possible to show the differences between the two species. 

"These genetic indicators distinguish the Hen Harrier and its close relative the Northern Harrier, genetically as well as morphologically, suggesting geographical isolation is enough to form two distinct lineages," added Dr Etherington. 

Further evidence from another study which provided additional data for Dr Etherington's paper also found that Northern Harrier was, in fact, more closely related to the Cinereous Harrier of South America than the Hen Harrier of Eurasia providing further evidence that the forms represent two distinct species.

Apologies for the lack of local news and views on Another Bird Blog this week. The weather has been most unkind with lots of rain, endless grey days and a lack of sunshine.  Things can only get better.

Thrush And Goose

Lots of Fieldfares were on the move today. And later there was a bonus bird in the shape of a Greenland White-fronted Goose. 

I’d started off as usual with a drive north towards Pilling and Cockerham. The flood at Braides Farm was partly frozen where my distance-impaired counts still realised approximately 250 Lapwing, 140 Golden Plover, 180 Curlew, 40 Black-tailed Godwit, 20 Redshank and 40 Teal. There was a very tightly packed flock of about 400 gulls, mainly Black-headed, but also some Common. A black mass of birds was immediately recognisable as a post-roost huge flock of Starlings, and as they slowly dispersed left, right and centre in smaller feeding parties I counted 600+ and still some left on the ground. 

Starling, Golden Plover, Lapwing

There was very little doing at Conder Green where the recurrent high water level made for a poor show on the pool. Best I could manage here were 40+ Wigeon feeding across the bund at the back of the pool, a few dozen Teal, a couple of Little Grebe, several Curlew and the obligatory Little Egret. But, 200+Teal in the creeks and the wintering Spotted Redshank.

There had been a few Fieldfares flying over Conder Green but a drive along the lanes of Jeremy and Moss suggested something of a new influx, precipitated perhaps by the overnight drop in temperatures and the overnight frost. 

For readers who do not know our northern Fieldfare Turdus pilaris, it is a highly gregarious but intensely shy member of the thrush family of the Northern Hemisphere. It is very different from, but immediately separatedfrom our native UK thrushes by way of its mobile tendencies, loud ‘chacking’ call and flocking behaviour both when feeding and during its autumn migration from Scandinavia. 

Fieldfares

It was hard to count the Fieldfares as flocks of them moved continually inland by following the hedgerows of Moss Lane and then across the A588 towards Thurnham Hall and beyond. There seemed to be few Redwings amongst the approximately 300 Fieldfare and of course the two species do not always coincide in the timing their migration. 

Fieldfare

At Cockersands I located more than 20 Tree Sparrows, 30+ Goldfinch, 12 Collared Dove and a Pied Wagtail before I hit the road again and back towards Pilling in search of more. 

I checked out a potential new ringing site offered by a local farmer where I found 40+ Linnets in attendance but using a very narrow and extremely long strip of land which might rule it out as a workable project. Not to worry, it is a useful place to keep an eye on and I did see more Fieldfares in roadside hawthorns, plus a watchful Buzzard which scattered the Fieldfares as well as feeding Woodpigeons. The farmer tells me that Buzzards wiped out all his leverets this year, which if true doesn't help the raptor's already dented reputation in the tight-knit farming and shooting community. 

Buzzard

The many thousands of Pink-footed Geese have been incredibly difficult to pin down this autumn, due mostly to disturbance from autumnal farming activities, shooting pressures and disturbance from busy roads in sometimes semi-rural locations. Despite this continuous daily disruption the geese seem to find and use new and different fields in which to both feed and hide, bringing a truism to the old saying about the wisdom of undertaking a “wild goose chase”. 

At last near Lane Ends today I got sight and sound of the pinkies and with them was a single adult White-fronted Goose of the Greenland race – Anser alibfrons flavirostris, in the company of c500 Pink-footed Geese. The appearance of European or Russian White-fronted Goose of the race albifrons and Greenland White-fronted Goose of the race flavirostris differ in a number of ways. 

White-fronted Goose - Greenland race

The Greenland White-fronted Goose always appears darker than the European White-fronted Goose at rest and in flight. The belly-barring on adult birds is on average more extensive on flavirostris than on albifrons. The bill of adult Greenland White-fronts are orange-yellow at the base, but can be more pinkish-yellow on the outer-half, thus close in colour to European white-fronts on some individuals. 

I spent a while with the geese before brightly clad and slow moving cyclists caused the predictable flight to pastures new, all of the geese and yours truly back home for a warming coffee.

Friday on Saturday

I’m a little late with yesterday’s blog post. That’s because Friday evening was the annual Fylde Ringing Group Christmas dinner, a chance for members to get together and discuss birds for a change! A good time was enjoyed by all at The Farmer’s Arms, Great Eccleston. 

Farmer's Arms

Meanwhile the Linnets don’t get any easier to catch even though there are up to 300 birds present at any one time. Another session at the set-aside on Friday saw us add another eight birds to the project total. 

Linnet

Male Linnet

We recorded our first recapture - a first year male originally caught on the very first visit of 3rd October 2016, now re-trapped 2 months later, despite eight other visits in the intervening period. This is the first real indication we have that some of the Linnets probably visit the field on a regular basis. Our overall total of new birds ringed is now approaching 150 individuals out of a seemingly unchanging flock of circa 300. Almost certainly the daily flock is comprised of a mix of regular visitors, periodic callers but also a steady stream of new arrivals to replace those which moved on to other locations. The total number of Linnets involved in the two month period must number in the high hundreds rather than any daily count.

In the field is one plant in particular that the Linnets appear to favour; it looks to be a member of the Cruciferae family of plants and is known as Fodder Radish which at this time of the year displays brown/straw coloured pods containing rows of tiny brown seeds. Many of the now dried up pods have split open or are partly broken so that the seeds are still visible or have popped out onto the ground below.

Fodder Radish

A local farmer stopped to talk and invited us to take a look at his own set-aside plot half-a-mile away and for us to judge if this plot might be suitable for additional or complementary ringing. We found the spot, a strip of land located next to a drainage ditch of phragmites reed and other vegetation plus a substantial but cropped hedgerow along one side. It does look suitable for a spot of ringing so I will in the next week or two make regular visits to assess the species and number of birds present and take it from there. 

Afterwards I looked at the fields near Backsands, Sand Villa and Braides Farm where the wet fields have attracted a good selection of waders and wildfowl. In particular were good numbers of Black-tailed Godwit, a species which has the knack of finding partly flooded fields in which to feed.

True Grit

Luckily, and after studying the weather forecast I’d prepared well with a good breakfast, double socks and outdoor clothes warming over the kitchen radiator. Minus four (-4°) flashed the temperature gauge as I set off towards Pilling to meet Andy for 0800 at Gulf Lane where we hoped to catch more Linnets. 

We set the usual 3x single panel nets in the frosty, low vegetation and retired to the car for a coffee or two until the birds arrived. Initially the Linnets seemed not to visit the seed heads in the field of set-aside but to instead spend time perching along the roadside barbed wire fence that faced into the slowly rising sun. 

A good number of them also spent time in the roadway taking grit from the surface until approaching cars forced them to fly off. Grit is eaten a lot by seed eating birds. The grit accumulates in the gizzard and helps to break down any tough seeds by abrasive action to make the seed more easily digested. Remember, birds have no teeth with which to munch their morning muesli. 

Linnet

The Linnets were well up to recent numbers by way of an estimate of 250+ individuals sticking to two or three distinct flocks that split and then re-joined after being disturbed by passing vehicles, or often, an unknown cause. There was a Kestrel sat atop a distant tree that kept watch on proceedings and in the course of a few hours made two unsuccessful passes to grab a Linnet, a distraction that probably helped the flock to become increasingly jumpy and nervous of feeding. Or perhaps the Linnets were waiting for the overnight frost to clear a little before they began their breakfasting? 

Kestrel

Frosted Linnet field

We didn’t catch well with just eight new Linnets, although that increased our project catch to over 130 so far this autumn/winter. As the winter deepens it could be that the Linnets all depart, and even though there is plenty of natural food left for them to go at, the plants are now at virtual ground level which makes it more difficult to intercept them in flight. 

Do we carry on with minimal but perhaps catches of less than ten birds each time? It’s up for discussion but on balance we probably should continue as lowland wintertime Linnets are not caught in any great numbers in the UK, and certainly not in this part of northwest England.

Any data we collect will add to that already in existence and hopefully give a little more insight into the origins, movements and composition of both individual Linnets and Linnet flocks. Other birds seen at the set-aside, but more correctly in the attached drainage ditch today – 1 Little Egret, 6 Snipe and 1 Teal. 

Little Egret

Back soon with more birds on Another Bird Blog.

Berry Time

The morning started with a double first of the winter – a squirt of de-icer on the windscreen followed by switching on the heated screen and bum warmer. I’m all for gadgets that do away with scrapers and icy fingers, not to mention enjoying the luxury of a cosy backside while birding. 

The heater was on full blast as I drove slowly east over Stalmine Moss and towards Cockerham. On the outskirts of Pilling village I watched a Barn Owl hunt over the whitened fields. “Rather it than me” I thought as I watched it glide along the icy gullies and then slowly vanish into the distance of the next farm. 

Barn Owl

I stopped at Gulf Lane to check on the Linnet flock and found 200+ comprised of three or more highly mobile groups still finding food in the single field of set-aside. A bird ringer in Scotland contacted me to ask about the composition of the seed mix as he too is interested in a Linnet catching project. Richard the farmer tells me it is a standard wild bird composite from Oliver Seeds but with added wildflower mix. Whatever it is, it certainly works by keeping the Linnets coming back for more and where good numbers of them have found food for the last three months. 

Linnet

At Sand Villa and Braides Farm my combined counts gave approximates of 350 Lapwing, 250 Golden Plover and 120 Curlew, but also 8 Whooper Swan, 4 Teal and 1 fence hopping Buzzard. 

At Conder Green counts from the pool and the creeks approximated wildfowl to 240 Teal, 130 Mallard, 22 Wigeon and 8 Little Grebe. Otherwise, 3 Little Egret, 18 Redshank, 6 Curlew, 1 Spotted Redshank. 

I hoped for a few Goldeneye at Glasson where a frost or two often makes the diving ducks vacate the estuary for the increased temperatures of the yacht basin. But not today, although the numbers of Tufted Duck look to be on the increase with 34, plus a single Great Crested Grebe. 

A drive around Moss Lane and Jeremy Lane proved useful when I located a flock of about 250 mainly Fieldfares with but a handful of Redwings. It was exactly a week ago when a drive around the same fields produced much the same result except that I don’t think these were the same birds today, just new arrivals finding the same food source of hawthorn berries. 

The Fieldfares proved difficult to pin down to any particular stretch of berries when at one point more than hundred flew en-masse towards the main road and in the direction of Thurnham Hall. That still left a hundred and more in the original spot but where cars speed past to constantly stop the birds’ attempts to feed. 

Our winter thrushes are intensely shy, little wonder when on their winter journeys they are subjected to intense hunting should they reach France and Spain. Once again I sat motionless in the car hoping to picture them in the hawthorns. A little success. A few pictures of both birds and berries.

More Repeats

The weather is much like the TV channels at the moment with no originality, lots of repeats and nothing much to enthuse over. Day after day of wind and rain here in northwest England has seen me sitting in front of the PC most days while wondering where the next blog post will come from. 

More of the same beckoned until late on Tuesday night, but then on Wednesday morning the rain finally stopped, the wind dropped and the sun almost shone. 

Pilling to Cockerham road

I met up with Andy and Dave at Pilling for another crack at the Linnets. Despite the recent rains I’d kept an eye on the Linnet flock with a couple of visits showing that contrary to my fears of a week ago, the Linnets had not entirely deserted this particular food source. Visits between 12th and 21st November gave counts varying from as low as 40 birds or as high as 230, so there was everything to play for this morning. 

Linnets

We donned wellies to enter the field of set-aside and splashed along the previously dry path to where the crop had now lost most of its autumn height. Linnets were around in some numbers and confirmed recent counts of 200+ but we managed to catch just eight as they proved very adept at feeding around our nets without going in.

Being a bird ringer quickly teaches you that birds are cleverer than we humans think. I’d swear those Linnets were trying their very best to avoid us this morning.
