Revtangen BO March 30th

Finally a break in the bad weather. The whole easter holidays disappeared in wind and rain, apart from a catch of 25 birds (mostly Common Blackbirds) one evening on the 24th. Today there was a faint breeze from the east in the morning, turning NW mid-day and increasing a little. Mostly sunny. Nets open 06-14, netmeter hours 2850.

A small catch of Common Blackbirds and European Robins around dawn made up the bulk of todays catch. The first Eurasian Woodcock of the year was also caught. 

Eurasian Woodcock, adult (3cy+). Rugde, 3K+.

Eurasian Woodcock 1, European Robin 8, Common Blackbird 6, Goldcrest 2, House Sparrow 1, Tree Sparrow 1, Hooded Crow 1, Common Chaffinch 1, European Greenfinch 1, Yellowhammer 2. Total = 24. Also 2 controls.

The bird of the day was undoubtedly this adult male Pied Wagtail. It was wearing a BTO-ring, and after a long photo session the complete ring number was secured.

Slow start to the trapping season

The 2016 trapping season has started, but so far only a couple of days with some notable arrivals of mainly Common Blackbirds. Before alle the nets were put in place we invested five days with garden work, including treetop cutting and opening the "pond-area" a bit more by removing a few trees and bushes. We also spent a full day with some "heavy" machinery, removing black-list species such as Rosa rugosa and Japanese Knotweed Reynoutria japonica. We also dug 3 new ponds, and we hope to fill these with water during April.

Another slightly smaller pond is created next the the one we made in 2015, with a narrow "channel" between them.

Removal of Japanese Knotweed (to be replaced with a pond mainly covered in aquatic plants).

Most nets were put up on March 11th, and by March 17th the bird observatory was fully operational. So far 101 birds have been ringed in 2016, around 40 of these have been migrants, incuding 39 Common Blackbirds and 2 European Robins. In addition, we have controlled 66 birds, including a very surprising adult male Common Blackbird with an Icelandic ring!
