A Sunny Summer Day at Slimbridge


We are well into the time of year that some birders call the summer doldrums, meaning that birding tends to be rather slow in the summer post breeding season. So I had a very pleasant and laid back day at Slimbridge this week.

 

I made use of the 08:15 early entry for members and made my way down to the summer walkway in an attempt to see the returning White Spotted  Bluethroat.  I narrowly missed seeing the post breeding family of elusive Bearded Tits which had been seen by the volunteers at the Shepard’s Hut before I arrived. It is assumed that they bred in the reed beds next to the river Severn. After an hour or so the Bluethroat put in a brief somewhat distant appearance on one of its favourite twigs.  In all honestly, it was looking a little tatty in moult. Remarkably, this is the 5th year that it has returned to exactly the same spot and I’ve managed to see it every year. Bluethroats breed in central and eastern Europe  through to Asia so quite why it is persistently coming back to Slimbridge in a hopeless quest for a mate is anyone’s guess. It has now spent some 20 plus months singing and displaying at Slimbridge. I would guess that its coming to the end of its natural life span so I think its safe to assume that it won’t be contributing to the wider Bluethroat gene pool.

    

Wader numbers are slowly increasing as birds return from their northern breeding grounds. These are likely to be a mixture of failed breeders and, in the case of some species, females who abandon the males to all post laying parental activities. 

 

Green Sandpipers fall into the latter category with the first returning birds arriving at Slimbridge in June. There were four birds somewhat distant on the shoreline from the Stephen Kirk hide. I hoped they might move around to the Rushy where they would have been much closer and easier to photograph but they stayed put all day.


Returning Godwits were spread around the reserve in some numbers, many still in their attractive rusty brown breeding plumage.



A spotted Redshank on the South Discovery lake was moulting from its jet black summer plumage into its much duller winter plumage. Somewhat strangely, it is only in this stage of moult when its plumage truly matches its spotted label.


     


 

Avocets were well represented on the Rushy and South Discovery lakes, some still on eggs many with small youngsters in attendance. Avocet chicks are precocial. This means they hatch with a good degree of independence, covered in downy feathers, with their eyes open, and are capable of walking and feeding themselves shortly after hatching. They are also able to swim and dive soon after birth. One of the volunteers told me that all of the first brood chicks had been predated by crows. I guess they had young of their own to feed. So far the second batch have not succumbed to the fate of the earlier chicks so fingers crossed.

 

On the way out a Painted Lady butterfly, the first I have seen this year, was feeding on a buddleia bush.

Albert the Albatross

  What is more improbable -   a)     England’ football team    beating Germany in the knockout stages of a major competition   b)     Seeing an Albatross in England   Actually the answer is a) because it has not happened since 1966 rather than b) as Albert the Albatross, as he is affectionally known, has made a number of passing visits to the UK since 1967!   On Monday evening reports started to emerge of Albert associating with the Gannet colony at RSPB Bempton Cliffs in Yorkshire, almost one year after his    last brief visit to the same site. During the intervening period there have been a number of sightings of Albert across Europe, particularly from the Baltic Sea where he appears to have spent much of the last 12 months. In fact there were reports that he had been attacked and killed in the area by two eagles.    Reports of his death were clearly greatly exaggerated!   The Black-browed Albatross is ci...

The Hawfinches of the Forest of Dean

   Hawfinch - Forest of Dean, winter 2017 A highlight of my winter birding is my annual trip to the Forest of Dean to see Hawfinches. I was unable to go last year due to the post-Christmas lockdown so this year’s visit was even more richly anticipated than normal.   Parkend in the Forest of Dean is my usual chosen location for watching Hawfinches. Here the proven technique of using your car as a hide normally works well. I must also say that,  after a number of quite strenuous twitches recently, I was also looking forward to a much more leisurely birding session!   The story of Hawfinches in the UK is, to my mind at least, a fascinating one. It is what is known as an eruptive species meaning that it occasionally erupts from its traditional breeding grounds to invade on mass countries much further away. This is thought to be driven by a combination of breeding success and local crop failure resulting in not enough food to go around.    Records indi...

A visit to see a controversial Canvasback and thoughts on its provenance

   Canvasback ( its the one with the long black beak) curtsey of Nick Truby   Ornamental ducks are perhaps the most difficult and controversial birds that are on the current  British bird list. They are widely kept in collections and as such differentiating a genuine wild vagrant from an escapee is extremely challenging and sometimes impossible. I’ve discussed the issue of proving a birds provenance before, see here , but in summary a ring or isotopic analysis of a sample are required to prove beyond all doubt that the bird is a genuine vagrant. In the absence of this objective evidence of origin much more subjective factors are used to prove that the bird is “probably” a genuine wild bird. You could, however,  strongly argue that in the absence of the definitive evidence above, none of these ornamental ducks should be on the UK list of accepted wild birds   The Canvasback is the North American cousin of our common Pochard and is kept in some UK o...
