Grafham Water - 12 April 2013

A change in the weather system with combination of a westerly airstream which encouraged summer migrants to move northwards and showers which dropped them in to feed and rest.

Spent four hours from 06.40 covering most of the site except the far west end.

The first-winter male Velvet Scoter was still off the Dam as was a single female Red-breasted Merganser and 14 Wigeon. Good numbers of Goldeneye still with 141 counted including a very flighty flock of 96 off the dam which may well have been migrants stopping off. A pair of Goosander flew high east. 8 Avocets were on the lagoons and 10 Redshank were along the Dam. 3 Yellow-legged Gulls (1 4th calendar year bird, 2 adults); 22 intermedius Lesser Black Backs were off the Dam early morning then headed off high north-east as did a tight migratory flock of c450 Black-headed Gulls. 6 Common Terns flew through north with two lingering off Mander. 


Male Avocet - 8 were on the Lagoons today 

An arrival of Hirundines was evident - c. 30 Swallows off Mander with 8 through north-east, 16 Sand Martins also off Mander with 7 through south-east and 14 House Martins through east. 



Sand Martin resting 

Singing Chiffchaffs were in evidence, 32 were counted and there were 3 singing Willow Warblers. Still c. 35 Redwings were at the north end of the Dam with c. 200 in Diddington Wood though none were seen elsewhere. A single male Yellow Wagtail was below the Dam then flew off south, a White Wagtail was at the Lagoons, 16 Meadow Pipits at the Dam and a single Rock Pipit flew north. 6 Siskins were at the Lagoons. 


Redshank - were unusually confiding on the Dam this morning...
