Kvismare fågelstation, Sweden - Day 50

1cy male Greenfinch/Grönfink
Wing and tail of 1cy male Greenfinch - Note how yellow on outer web out outer two tail feathers touches shaft of feather, and extensive yellow in the primaries, even at this age.
Incredible wing-deteriorating disease or disorder in a 1cy male Blackap/Svarthätta. Never before have I ever seen this!
Brown Long-eared Bat/Långörad fladdermus found its way into the elevator net. Incredible little mammal!

This morning we were really excited about the possibilities of Ässön as there was rain over night followed by a light 1m/s wind from the north. Strangely, it never really kicked off, presumably due to mild weather, so we 'only' managed to catch 70 new birds and 4 recaps.
There wasn't really any highlight species today except the 2nd Dunnock of the season and a very interesting Blackcap that appeared to have extensive wing-deterioration on almost all of the flight feathers! It made it look incredible short winged when it had its wings closed. Most peculiar!

Reed Warbler - 13 (1)
Sedge Warbler - 4
Willow Warbler - 10 (1)
