Revtangen BO January 11th

Cloudy, light easterlies. Nets open 11-17, netmeter hours approx. 1500. Playback on Fieldfare the last 3 hours. No birds used the trapping area for night roosting, therefore the catch was limited. 

Ringed: Fieldfare 10, Redwing 3, Tree Sparrow 3, Chaffinch 1, Mealy Redpoll 5. Total = 22. Also 8 controls, including a female Yellowhammer ringed as a 1cy in September 2014.

Revtangen BO January 8th

Another calm day, 3-4 degrees and cloudy. Very little wind. Nets open 08.30-18, netmeter hours 2500. Playback on Fieldfare all day and (in the morning only) Redwing. 

Ringed: LONG-EARED OWL 1, Winter Wren 1, European Robin 1, Common Blackbird 1, Redwing 8, Fieldfare 22, Common Starling 1, Tree Sparrow 7, House Sparrow 1 and Greenfinch 1. Total = 44. Also 8 controls. 

A 2cy Long-eared Owl was the surprise catch of the day. We've noticed that the thrushes settle quite late when it's almost dark, and this is a good time to catch them. An owl is always a possible bonus after dark but this species is less than annual at Revtangen BO.

Revtangen BO January 5th

Nice weather with mostly sunny/part cloudy and very little wind. Nets open 08.30-17.30, netmeter hours approx 2300. Playback on Fieldfare in the afternoon. Still unusually many thrushes around, and the 2018 season got off to an excellent start.

Ringed: Collared Dove 1, Winter Wren 2, Common Blackbird 3, Redwing 10, Fieldfare 49, Tree Sparrow 4, House Sparrow 2, Chaffinch 5, Brambling 1. Total = 77. Also 9 controls. 

Redwing 2cy. Good numbers of Redwings and Fieldfares are wintering in Norway this season, in part because thare are lots of rowanberries in central Norway, in particular in Nordland county.
