A semi-lifer: ‘British’ Western Yellow Wagtail

I simply could not resist not to go out today for another spring bird walk so packed up with the whole family and took a taxi to Caldecotte Lake in a beautiful weather. My wife stayed with our daughter at the play-ground and I decided to walk all around the lake. The number of waterbird species was very low but there were some songbirds which were new for this year. I found a couple of Eurasian Coots and Mute Swans incubating as well as some possibly guarding drake Tufted Ducks on the south lake.

At the south end of the south lake I saw the first Common Swifts of the year flying together with a dozen of Common House Martins over the Amway HQ. Sedge Warbler was also a new bird for the year. Some birds were singing on the western bank of the south lake. Just next to the sailing club I saw two British subspecies of Western Yellow Wagtails (M. f. flavissima) (alternate name is Yellow-crowned Wagtail). I was happy with this find as I have never seen them before. I probably have a better view of them in the coming days.

At the north lake a Carrion Crow hunted on a Grey Squirrel and almost collided with a tree after a sharp turn made by the scurried squirrel. At the northern point I saw a female Eurasian Sparrowhawk diving with legs outstretched like an Osprey when hunting. Just after the the sparrowhawk disappeared behind the woods I found a Western Osprey gliding over the lakes towards Willen. This time the sunglass helped a lot to pick up the bird in the sky.

I will revisit the area soon to survey breeding birds around the lakes.
