A juv glaucous gull was starting to moult from its juv plumage. This bird shows some new scapulars, wing coverts and one new tertial. Iceland and glaucous gulls retain thier first set of feathers (juvenile plumage) until the spring so these are the first new feathers this bird has grown since leaving the nest.
At Prescot reservoirs this morning my first house martin of the year was with 6 swallows and 45 sand martins. Blackcap, willow warbler and chiffchaff singing. BH reports common tern from Carr mill dam this morning.
I had a quick look around Howards lane to see if the cattle egret had returned but no sign.
