16th April 2009

A dark and misty morning that looked promising but failed to produce the warblers of yesterday, though still came up with two new spring arrivals for this year. A fine second calender year male Redstart (left) was trapped and ringed and a Whimbrel called around the island to announce its arrival and showed well during its first sighting this spring for the obs members.
Just a single Willow Warbler in contrast to Red Rocks that had many more warblers, exactly the reverse of yesterday, strange is the mysteries of migration.
Swallows were counted at 121 after a good passage in the afternoon, with 2 House Martins, and 20 Goldfinches and a Siskin being the only finches apart from 40 Linnets, some of which may be the residents breeders.
Other migrants were 100 Meadow Pipits, 5 Wheatears and 3 White Wagtails (a lot fewer than yesterday). A Wood Pigeon and 2 Canada Geese were logged later in the day.
Twenty Gannets and 10 Sandwich Terns was a reasonable return for a low tide with an easterly wind.
A member walking off the island recognised a 'ringtail' harrier, probably Hen Harrier as it flew over the shore, across the marsh and then inland to the golf course.

Ringed today:-
1 Common Redstart (right)
1 Goldfinch
1 Willow Warbler (left)

The Redstart was aged by a moult limit in the greater coverts and the wear in the tail.
The Willow Warbler shows the long primary projection that can distinguish it from Chiffchaff in the field.
