Phil has already mentioned the roost, more later.
Arrived at 7am (1st light), Rob G was already at the gate. The gull roost and the rest of the roosting birds were still settled, possibly kept down by the strong SSW wind. but by 7.45AM most of the roost had left. I then attempted a 'VIS MIG' session, but the wind was too strong and in the wrong direction.
But somehow a few meadow pipits, skylarks and redwing got through the adverse conditions heading south. The male stonechat performed well at the back of the 1st Flash. But generally things were quiet, other than the usuall finches feeding on the saltmarsh and ducks dabbling in the shallows. I opened the new sluice to gauge how much water we can drop off in a set period. By the end of the day, the periphery had a broad belt of mud. I would like to think any passing waders would be dropping in tomorrow. With the roost building up, I decided to stay and complete the whole dawn till dusk shift.
Pied wags were gathering in good numbers in front of the hide on the newly exposed mud , as were the snipe in the southern end. A small flock of starling circled and later roosted in the 3rd Flash reeds, where surprisingly the pied wags followed. But my attention swiftly turned to the massed ranks of gulls. The BHG's were streaming in, well it was more of a torrent really. A 1st winter common gull was the highlight, but then from nowhere, large gulls were falling out of the sky. The Flashes were soon overwhelmed, the 1st and 2nd Flash were full of gulls and the central area too was cheek to cheek. After receiving a text from Brian Stretch, that a 'baltic; type gull had just left Grimley with BHG's heading ENE, the emphasis on the BHG's shifted to the big boys. The range of ages of LBBG and herring gulls mixed with different forms of each can be a daunting task, if you are at Bartley. But at upton with only 1500 birds, its a bit easier. Anyway after finding an adult yellow legged, a good in itself, I couldn't believe my eyes:eek!: when a small, white headed, 'black' (upper parts ) gull walked out of the crowd the - BALTIC GULL. What a beauty, most noticeable was the long, completely black primary projection. Other features included:- yellow bill with an orange red spot on lower mandible tip, white unmarked head accentuated by the black upperparts, small eye, bright yellow legs, the white tipped tertials contrasted markedly with the rest of the black wings and upperparts. The white 'mirror' of P10 (10th primary) was seen on the underwing. In flight the underwing appeared mostly dark. All in all a cracking bird.
