An Isabelline Shrike in Devon 14th October 2018


Having seen my wife off on the train to Glasgow on Friday I had the weekend to myself and was looking forward to getting out and about to do some birding.This idea was soon scotched by the onset of rain and wind later that day and my optimism was replaced by a pervading sense of gloom as I contemplated the prospect of a weekend confined to remaining on the couch at home. Never something I can countenance with equanimity for very long.

A rare Isabelline Shrike had been reported daily from a seaside village called Thurlestone on the coast of South Devon for the last few days and this had sparked my interest. It was still there on Saturday. By Sunday I was feeling distinctly fractious as another day of rain and wind presented itself to me as I looked out of a rain spattered bedroom window onto a soggy wet lawn below. It was all too obvious how heavily it had rained in the night. I checked the forecast and a ray of hope presented itself with a prediction the rain would gradually move eastwards and maybe by lunchtime Cornwall and Devon would be free of the rain.

It was a long shot but I just had to get out of the house so I decided to go for the shrike which had already been reported from Thurlestone early this morning, despite the rain. I left home in a continuous downpour at just after nine and headed west through the North Cotswolds, the trees lining the rural roads looking distinctly autumnal now in shades of gold and yellow, while the endless rain stripped leaves from the branches, sending them falling in whirling parabolas across the partially flooded roads.

I joined the Motorway and entered a living hell of opaque spray and fast moving vehicles. I took it easy in the inside lane as there was no real hurry and I certainly did not want to arrive at Thurlestone  in the rain. Two hours later, Marge (the satnav) directed me off the Motorway onto still wet and partially flooded secondary roads and we wound our way through the increasingly narrow lanes leading towards Thurlestone. The road, sunk between high banks, eventually became just a single carriageway lane for the last two miles with passing places but this did not seem to deter the locals from driving at breakneck speed and it was with relief that I finally entered the small, cramped village of Thurlestone, situated on a hillside above the South Devon cliffs.

By now the weather was improving, it had stopped raining and there were even patches of watery blue showing through the mainly grey and white clouds. A sliver of optimism permeated my being.

The first impression I got of Thurlestone was hardly one of benign welcome, as, like many scenic west country coastal villages, traffic has come to dominate and govern the life of a village which once must have been a tranquil and delightful place to live.The narrow road that winds through and around Thurlestone is embellished with continuous double yellow lines, and parking a car anywhere, if you are not a resident, is virtually impossible. The village's situation is such that it cannot possibly cope with many cars and what it must be like in summer does not bear thinking about. It must be a nightmare, both for the residents and visitors alike. 

I also got the impression that Thurlestone is quite an upmarket place, with, at one end of the village, a private lane down which I had to walk, bordered on both sides by absolutely huge, tasteless, modern houses commanding prices in excess of a million pounds, leading to a golf course that lay between the end of the lane and the coastal cliffs above the sea. 

The Millionaire's Lane leading to the golf course and cliffs
My first priority was obviously to find somewhere to park but there was nowhere and in the end I drove out of the main part of the village and found a quiet cul de sac further up the hill and where I am sure I should not have parked but no one came out to object. It was a wet Sunday after all and outside of the tourist season.

I got my gear together and walked downhill and back into the village, past the church and village stores and down 'Millionaire's Lane' its entrance guarded by stern notices saying access for cars was by permit only.

'Millionaire's Lane' leading to the golf course and cliffs
Passing down the lane I came to the golf course with yet more hostile signs saying no right of way except on the public footpath that crossed  diagonally towards the coastal footpath running along the edge of the cliffs.


The view from the coastal footpath, looking down and southwards out to sea
The instructions on RBA (Rare Bird Alert) told me to head for a green tin hut and then turn left onto the coastal footpath and the shrike would be found in an area of rough grass and brambles situated between the edge of the seaward side of the golf course and the coastal footpath.

I headed off across the golf course and duly turned onto the coastal footpath by the green hut to join a half dozen birders, standing and regarding the rough area of brambles and scrub.

Birders on the coastal footpath and the Green Hut beyond
Enquiring about the shrike I was told it was here but was currently out of sight as it spent a lot of time perching low in the brambles to keep out of the strong northerly wind. Just at that moment the shrike flew up to perch prominently on a spike of bramble.



It then flew closer and I took a few photos of it perched in the brambles before it flew further up the sloping area of rough ground and was, once again, temporarily lost from sight.





After a while it became obvious the shrike had certain perches it preferred to hunt from and contrary to what I had previously thought it was quite happy to perch relatively high up and prominently, braving the strong wind without any apparent discomfort, swaying and balancing in the gusting wind whilst looking about for prey.








Being a Sunday and with the weather now set fair, the coastal footpath was becoming well used and almost crowded with serious walkers and people just out for a stroll. Invariably they would stop to ask us what we were looking at but after a while this got a little tiresome as there is only so many times you can repeat oneself. So I walked into the rough grass away from the footpath, not so far as to disturb the shrike, but far enough to not have to answer anymore enquiries.



The shrike carried on hunting insects from its various favoured perches and it appeared to have little problem in locating and capturing prey. I saw it catch various unidentified insects including a bee and a hoverfly. On a couple of occasions it flew high up into the air above us to seize a high flying insect and then descended in a bounding, bouncing flight back to the brambles.

The overall colour of the shrike was pale sand brown on the upperparts and creamy white on the underparts which also showed some scaling on the flanks. There was not a major contrast between the upper and underparts, thus creating an overall image of a pale looking bird. The indistinct darker brown face mask on this bird extended only from the eye backwards across the top of the ear coverts. The unmarked rufous rump and tail being the only parts of the bird that were strongly coloured. Judging by its plumage, which was fresh and almost pristine, this was a first year bird making its maiden journey south and managing, in this case, to get it spectacularly wrong.


The first part of the bird's name, Isabelline, comes from the Latin word isabellinus, used to describe a colour that is greyish yellow and thought to be based on the unsavoury historical fact that Isabella the First of Castile (1451-1504) is said to have promised not to change her undergarments until Spain was freed from The Moors! The paleness of its plumage certainly served it well when it was perched low down in the similarly coloured pale stems and dead withered grasses, as it became almost invisible until it moved.



The taxonomy of the Isabelline Shrike is complicated and still open to some conjecture and mild controversy. Isabelline Shrikes were at first thought to be conspecific with the more familiar Red backed Shrike and it was only much later that it gained full species status in its own right, but as from 2018 the Isabelline Shrike has itself now been superceded and split into two species, Daurian Shrike and Turkestan Shrike, although Isabelline Shrike is still used when it is impossible, for us mere mortals at least, to differentiate between what are two almost identical species.


The separation of Daurian from Turkestan Shrike is based on subtle plumage tones which themselves are notoriously variable due to differing light conditions, hence the uncertainty concerning the Thurlestone individual's true identity, which has yet to be convincingly established.  It is likely to be Daurian, as that species, based on past records, is the more prone of the two to wander to Britain and western Europe.

Daurian Shrikes breed from Mongolia and south and eastern Russian Transbaikalia south to north and northwest China and winter in Arabia and northeast Africa.

Turkestan Shrikes breed in western and north eastern China and partially overlap with the breeding grounds of Daurian Shrikes, which further complicates matters concerning interbreeding and the resulting progeny. Turkestan Shrikes do, however, winter in a separate area from Daurian Shrikes, being found in Pakistan and northern India.

Now that the Isabelline Shrike has been split into two species, at least for now, birders who keep a list are keen to establish that they have seen both Daurian and Turkestan Shrikes, although the latter is the less likely to occur in Britain and western Europe.

The Waders of Farmoor 10th October 2018


My local Farmoor Reservoir in Oxfordshire can host some very nice waders, usually either heading north in spring, when they are in a hurry to get to their breeding grounds and do not remain for more than a day or two or heading south in late summer and autumn when they are more relaxed and often linger for a number of days. 

Below is a by no means comprehensive selection of images of various commoner waders I have encountered and photographed over the years at Farmoor. I hope you enjoy them as much as I do. Behind every one lies a story, not just a picture, and that for me is the charm of it all. One glimpse and I am transported back as if it was only yesterday


Sanderling



Richly coloured individuals virtually in the full splendour of their hugely
attractive breeding plumage as they pause on their way northwards to the 
Arctic Circle.They were in the company of the less well marked individuals 
shown in the first three images below



The above three images show not so well coloured Sanderlings on their spring 
migration to the Arctic Circle. Note the variations in plumage colour and intensity 
but overall whiter appearance.Their moult could either not be so well advanced as the 
brighter individuals shown or they just will not get any brighter than this. Such 
breeding plumage variation is a well known characteristic of Sanderlings
This was an aberrant individual on its Spring migration in normal summer 
plumage apart from abnormal white feathering on its head and neck





The above five images show Sanderlings on their southward autumn migration 
when the plumage is worn and abraded and much of the breeding colour is lost
or faded due to wear. They will soon moult out of this plumage into a white and 
grey winter plumage


Knot





A Juvenile Knot.Juveniles have grey upperparts attractively 
scaled white or buff and peach coloured 
blush to their lower breast


Officially this bird's correct name is Red Knot. It's obvious why!

The above three images show an adult Knot on its spring migration.This 
individual is in full breeding plumageand showing the rich rufous face and 
underparts and chequered upperparts that it has already moulted into 
from its grey winter plumage
The same full summer plumaged Knot as above with another individual that was
accompanying it and possibly in its second year of life when they do not acquire
the richly coloured breeding plumage of a full adult.Often such birds do not
migrate north but this bird is obviously doing just that or at least has got to 
Farmoor but still has a long way to go to its breeding area in the Arctic Circle!

The probable second calendar year Knot. Note the virtually complete lack of
rufous pigmentation to the plumage


Ringed Plover







Adult Ringed Plovers on their southward autumn migration and still in full
breeding plumage when they are a very smart bird indeed 





Juvenile Ringed Plovers. Note the neat fresh feathers delicately
fringed with buff, the lack of bright orange on the bill and legs, 
lack of any band on the forehead and brown not black facial and
breast bands

Little Ringed Plover


An adult Little Ringed Plover in Spring.This could be a migrant going
further north to breed in Britain or a bird breeding on one of the many gravel
 pits around Farmoor. This is an adult male, told by its prominent yellow 
eye ring and well marked black bands on its head and upper breast.Note also
the thinner and entirely black bill compared to a Ringed Plover

Dunlin



Above three images
Dunlins on their Spring migration in full breeding plumage which they rapidly 

moult into from their grey winter plumage,Dunlins are by far the commonest
wader visitor to Farmoor especially in late summer/autumn



Above three images
Adult Dunlins on their return autumn migration when their plumage is worn,
and consequently much darker looking and less colourful

A Dunlin in complete juvenile plumage and yet to show any sign of  moult into
its grey feathers of winter



Above three images
These show juvenile Dunlins with a varying commencement of moult into
the grey feathers of their winter plumage


Juvenile Dunlins which can show a bewildering variation in plumage but usually
show the beginnings of their moult from streaked brown juvenile plumage to
winter plumage, as evidenced by the presence of a few grey feathers on the
upperparts.The above two images show individuals in complete juvenile
plumage


Black tailed Godwit





A Juvenile Black tailed Godwit of the race islandica which breeds in Iceland.
Its age can be told by the neat fresh feathers and scaly appearance to the 
upperpartsand dull brownish orange wash to the neck and breast

Little Stint















All images are of various juveniles in fresh plumage in autumn as they migrate
south.They will rapidly moult into an overall duller grey winter plumage
I have never seen an adult  Little Stint at Farmoor

                                                                 
Curlew Sandpiper







Juvenile Curlew Sandpipers.They are probably the most irregular of the
commoner wader species to show up at Farmoor and are by no means annual.
I have never seen an adult here, only juveniles in some autumns

Juvenile Dunlin left and juvenile Curlew Sandpiper right showing the slightly
larger size of the Curlew Sandpiper. Note also the latter's neat scaly plumage
pattern on the upperpart, longer legs and slightly downcurved bill giving it an

elegance denied to the dumpier Dunlin

                                                               
Common Redshank


An annual migrant in both Spring and Autumn, sometimes in small groups.
This was a juvenile in late summer at Farmoor

                                                                         
Ruff





The above three images show a juvenile male Ruff
Ruff (male) behind and Reeve (female) in front. Note the different coloured
legs of the male (yellowish green) and female (grey)
The juvenile male Ruff on the left and a juvenile female Reeve on the right.
Note the obvious disparity in size
Juvenile Ruff on autumn migration.The smaller bird is the female called a Reeve
the larger a male. Both have brown scaled upperparts when in juvenile plumage

                                                                       
Turnstone




The above images show Turnstones still in full summer plumage in late 
summer and still to moult into their drab winter plumage although the 
feathers on the wing are worn.it is always a delight to see these colourful
chunky waders

A Turnstone in late summer in transition to winter plumage with most of the
chestnut feathering moulted and black and white on the head being replaced with
brown winter plumage

This is probably a female Turnstone in late summer showing a less well 
marked head pattern and less colourful upperpart plumage
Probable female (left) and male (right) Turnstones




Turnstones are mainly seen at Farmoor on their autumn migration when they 
are often returning adults still in their colourful breeding plumage.


Grey Phalarope







Now virtually an annual autumn visitor to Farmoor.They are usually juveniles
in varying stages of transition from the brown of juvenile plumage to
the grey and white of first winter.Occasionally more than one will arrive at the
same time and exceptionally an adult will visit the reservoir

                            
Red necked Phalarope





A rare visitor to Oxfordshire let alone Farmoor. This juvenile graced Farmoor
for a few days in autumn 2017 much to everyone's delight as it allowed
very close views as it fed on the water. They are more delicate than a 
Grey Phalarope but equally hardy
