Something small, something dusky!

The last week here at Ottenby has been quite calm, with not too many birds caught each morning. Some mornings barely any birds at all! But last Tuesday we caught another little rarity, a Dusky Warbler. A new lifer for me!
We could hear it calling already in the Heligoland trap and the excitement kicked in! 
The bird was carefully looked over before It was shown to the birders flocking by the fence, here by Mikaela and Barbara, and below by the station's chief Magnus.
Dusky Warbler (Phylloscopus fuscatus). Quite dull, but still a nice bird!
 Yesterday we caught about 50 Redpolls, one of my favourites. With this amount of birds you have a good opportunity to look at the variation in and between the age groups and sexes (and subspecies, though this can prove quite difficult sometimes). Like below where I'm holding an adult (second calanderyear or older), to the left, together with a juvenile (first calanderyear). One character you can look at (though not exclusively) is the tail, where the juveniles have pointier and more worn feathers.
Common Redpoll (Carduelis flammea). You can tell that this is a male from the red feathers on the breast, females only have some red on the top of the head.
To continue on this educative theme, Gabriel Norevik held a little presentation/lecture about different ageing techniques and moulting patterns in Passerines. Interesting least to say! Here he's pointing out the moult limit in a young Siberian Rubythroat (Luscinia calliope).
Now I have less than a week left here at Ottenby and I'm afraid it will pass too quickly. After that it's about time that I start looking for a job for the winter!
