Revtangen BO November 17th

As incredible as it sounds - there was very nice, calm weather this weekend! Put up most of the nets from around 08-12, netmeter hours approx. 1200. Playback on Yellowhammer and Redpoll.

Ringed: Winter Wren 3, Common Blackbird 5, Redwing 3 (including one coburni), Blue Tit 3, Willow Tit 1, House Sparrow 1, Greenfinch 1, Mealy Redpoll 44, COUES'S ARCTIC REDPOLL 6, Lesser Redpoll 1, Yellowhammer 7. Total = 75.


With a winglength of 127 mm and a weight of 82 grams this Redwing was actually quite a bit larger than the smallest Common Blackbird trapped today. The size combined with a quite dark plumage with a lot of olive tone to it revealed our first Redwing of the western subspecies T.i.coburni this season.

Compare the undertail coverts on the "normal" Redwing with the undertail coverts of the coburni Redwing.

An interesting Coues's Arctic Redpoll trapped today. A few of the exilipes ssp. can show a deep orange face similar to what is commonly found in the nominate ssp. from Greenland and arctic Canada.

Norwegian summary of ringing results:

Ringed: Gjerdesmett 3, svarttrost 5, rødvingetrost 3 (inkl. 1 coburni), blåmeis 3, granmeis 1, gråspurv 1, grønnfink 1, gråsisik 44, POLARSISIK 6, brunsisik 1, gulspurv 7. Total = 75.
