Oxwich Marsh 20 July 2014

Ideal ringing conditions at the marsh this morning: a warm day with very little wind and overcast conditions.  We put 180 feet of net in the reedbed and a further 160 feet of net in willow and bramble scrub.  The results were excellent, with 125 birds of 16 species trapped.  The catch was as follows:

Species New Re-trapped Total
Great Spotted Woodpecker 1 1 2
Wren 3 1 4
Dunnock 1 5 6
Robin 2 4 6
Blackbird 0 1 1
Sedge Warbler 5 1 6
Reed Warbler 15 2 17
Whitethroat 5 0 5
Blackcap 14 2 16
Chiffchaff 1 0 1
Willow Warbler 1 0 1
Blue Tit 10 10 20
Great Tit 6 9 15
Chaffinch 4 1 5
Greenfinch 17 1 18
Goldfinch 2 0 2
Total: 87 38 125

The highlights of the catch were: the first fledged sedge warblers of the year, confirming that while the species appears to be present in very low numbers in the marsh, successful breeding has occurred; a control reed warbler and a good number of fledged juveniles of that species; a good catch of greenfinches, which takes us over the 200 new bird mark; a few fledgling whitethroats; and, consistently far higher catches of blackcap than in 2013.

One of the great tits trapped showed abnormal colouration of the claws.  A photo is below.  Any comments with regard to similar observations / how often it is observed would be interesting.



Thanks to Keith Vaughton and Charlie Sargent for company and assistance this morning.
