Revtangen BO December 14th

The last month we have been busy at the museum moving old stuffed animals to our storage facilities. At the same time the weather has been mostly poor. Last weekend, however, we discovered that a prominent guest from far away had found our feeder - an Oriental Turtle Dove had joined the local Collared Doves! Today the nets were opened and the bird behaved very well, trapping itself as soon as it arrived for breakfast. 

Nets open 09-11, netmeter hours approx. 600. SE 6-7 m/s, around 3 degrees, sunny. No playback. 

Ringed: ORIENTAL TURTLE DOVE 1, Blue Tit 2, Great Tit 1, House Sparrow 3, Tree Sparrow 4, Chaffinch 10, Mealy Redpoll 3. Total = 24. Also 13 controls. 

Incredibly, the 4th new ringing species for Revtangen BO in 2016, of which 3 have been pigeons or doves!

1 cy Oriental Turtle Dove, ssp. meena. There are approx. 18 records of Oriental Turtle Dove in Norway before. Mongolturteldue, 1K av underarten meena.

Revtangen BO November 10th

Light easterlies 4-6 m/s. Mostly sunny with a few clouds now and then. Temperatures from minus 2 to pluss 2. Nets open 08-17, netmeter hours approx. 3000. Playback on Fieldfare, Yellowhammer and Grey Wagtail.

Total = 94. Also 21 controls, including a Blue Tit not from Revtangen.

Including the bird from yesterday that was also controlled today, 4 Common Snipes were trapped in the garden today. Another(?) escaped the most southern nets mid-day. This occurence is puzzling to say the least, but it probably has something to do with the cold weather that has frozen up the ponds where they usually feed.

Observations: Goshawk 1 1cy made a narrow escape from a mist-net in the morning; Grey Wagtail 2, European Goldfinch 2, "Eastern" Bullfinch 2-3.

Revtangen BO November 8-9th

The prevailing weather this week has been cold and light-moderate easterlies, with sub-zero temperatures at night down to minus 5-6. We managed two short afternoon catches 1-2 hours before dusk on the 8th and 9th, targeting mainly thrushes that feed on apples we've put out. Only the middle nets around the feeder were in use. Playback also on Fieldfare, this species can be attracted by playback all day unlike the other thrushes that mostly respond to playback around dawn.

Ringed 8th-9th, netmeter hours in total around 300:

Common Snipe 1, Winter Wren 1, Common Blackbird 5, Fieldfare 24, Redwing 6, Blackcap 5, Long-tailed Tit 7, Blue Tit 4, House Sparrow 1, Tree Sparrow 5, Brambling 2, Greenfinch 4. Total = 65.

Revtangen BO November 6th

The wind was a bit too strong in the early morning hours, but later decreased to almost nothing and a pleasant afternoon. In late afternoon the temperatures dropped enough for our ponds to freeeze over in a relatively short time, so it appears the autumns is coming to and end.... nets open 07.30-16.30, netmeter hours approx. 2800.

Revtangen BO November 5th

Another cloudy and a b it too windy day, but the wind was in the east so worth a try. Despite playback on Fieldfare, Grey Wagtail, Long-tailed Tit and Bohemian waxwing there was not a lot to catch, as movements of passeries trough the area was very limited. Nets open 07.30-15.30, netmeter hours approx. 2500. 

Ringed: Grey Wagtail 2, Fieldfare 5, Common Blackbird 2, Redwing 6, Blackcap 4, Goldcrest 1, Long-tailed Tit 7, Blue Tit 6, House Sparrow 1, Tree Sparrow 3, Greenfinch 1. Total = 38. Also 14 controls. 

Observations: Lots of seaducks and some auks and loons were on the move over the sea. A 1 hours sample count 10-11 produced 2 Red-throated Loons, 2 Great Northern Loons, 740 Common Scoters, 17 Velvet Scoters, 1 Northern Pintail, 3 Wigeaons, 3 Teal, 11 Greater Scaup, 3 Razorbill and 10 Little Auk moving SW. A male Hen Harrier and a White-tailed Eagle flew by the station, and the british-ringed Pied Wagtail was still at Reve kai.

This Northern Pintail migrated in a flock of Common Scoters, didn't realize it was there before I looked at the pictures.

The Pied Wagtail with a BTO-ring was still at Reve kai today, first seen at the end of February. We have now received news from BTO that it was ringed as a 2cy male at Kessingland, Lowestoft, Suffolk on February 4th 2015. Svartryggerle.
