The gull numbers have really dropped down with weather becoming a little warmer of late. Probably a couple of hundred herring gulls on this grey rainy day. A huge argentatus herring gull was interesting . The mantle colour was obviously darker than the nearby argenteus and had a complete sub terminal band on p5 which possibly makes this an argentatus from northern baltic/southern finland area. According to 'Gulls' Olsen and Larsson state this population has more black on p5 covering both webs in 30% of population. This bird has pale eyes although they do look dark in the photos.
Sub terminal band on both webs of p5
A huge bird compared to nearby herrings. Look at the size of the head.
Prescot reservoirs, A 1stw and an adult yellow legged gull today. 35 Great black backed gulls was an excellent count for the res. A huge flock of pinkfeet lifted off the distant mooslands and filled the horizon and several skeins flew over the res . A dunlin was on no4 reservoir and 3 skylark over..
Prescot Reservoirs, The run of rare gulls continued with this 1st winter caspian gull at the reservoirs today . It showed briefly around midday and after some checking of the photos at home I was able to confirm it as a 1st w caspian gull. Several yellow legged gulls also today with 2 adults , a 2nd winter and a 1st winter was a good total among the couple of thousand herrings throughout the morning. A female goosander, 3 goldeneye, 3 pochard, 5 teal and 10 tufted duck on the still partially frozen reservoir.
A real rarity at the reservoirs is Glaucous gull and a juvenile today was the first for over 13 years. Glaucous gulls have been pretty scarce in the NW this winter and this bird was my first this winter. A nice addition to the ring billed and caspian gulls this winter at the res.
An adult med also today and BH reports a crossbill over this morning.
Ringing update, I have just received a reply about the ringed common gull at prescot reservoirs seen on 5th Jan 2010. It was rung on 10th july 2006 on the island of Amrum just off the north sea coast of Germany. It was then recorded each summer in 2007, 2008 and 2009 at Amrum and then finally by me at Prescot reservoirs in Jan 2010

Prescot reservoirs, 8 inches of snow and the reservoir 80% frozen A couple of common gulls of interest today. A red darvic ring with white letter and numbers A325 was on an adult common gull.

A leucistic 1st winter common gull looked very wintery in the blizzard conditions . Also adult med gull, 2 adult yellow legged gull, 3 goldeneye, 20 tufted duck,2 pochard , 10 little grebe and 2 snipe . BH reports 7 golden plover earlier.
