TS Saturday 21 April

Ringing updatesPosted by Peter Dunn Mon, April 23, 2012 07:56:18

The rain held off until around 11am, this time an hour later than was forecast and five of us manned the top scrub at Filey. Singing Willow Warblers and Swallows overhead showed that there were birds about. However migration this morning was more reverse than spring arrival with a number of 'grey' Robin, mostly 1st years (5's). These continental birds were held up on the coast and are much easier to age than some of the Brit ones. The ogc's have strikingly white tips and because the general plumage is grey, the diffrence in tone between the old and new feathers is much more obvious.

Other evidence of return migration was an increase in Blackbirds and those caught were carrying large amounts of fat.

The only summer migrant was a Chiffchaff

Totals for the Day 22 birds

Dunnock 4; Wren 1; Robin 5; Blackbird 2; Chiffchaff 1; Blue Tit 1; Tree Sparrow 1: and Linnet 7.
