A recapture Saw-whet last night!

With last nights banding with caught 3 Saw-whet Owls. 2 of them were new and 1 of them was a recapture!! The recapture rates on these owls are high because a lot of people band them in fall in the nortern states of the U.S and in Canada. It was pretty cool that we already had a Saw-whet recapture this fast, as we have only banded 6 Saw-whets so far! The three birds were a hatching-year, a second-year and an after-second-year.
Saw-whet Owl, hatching year; no moult pattern present
Saw-Whet Owl, second year; the typical moult pattern of a SY. The outer primaries and inner secondaries are new.
The recaptured bird. Eventhough it is really subtle it seems that you can distinguish three generations of feathers which makes this a ASY. The colours red and blue show the new feathers (generations).

The banding today was pretty slow, with 78 birds being caught. The internet was out this afternoon at the banding lab so I don't have the numbers yet. We didn't capture anything exciting although this orange-crowned Ruby-crowned Kinglet was interesting:


Winter Wren 1 -
White-breasted Nuthatch 1 -
Gray Catbird 1 -
Cedar Waxwing 8 -
Chipping Sparrow 1 -
Fox Sparrow 1 -
Song Sparrow 1 -
White-throated Sparrow 5 -
Dark-eyed Junco 12 -
Northern Cardinal 1 -
American Goldfinch 23 -

Total 55, 11 species

Tomorrow I'll be banding for a few hours in the morning before I take off to the airport, for a second try! I have now booked one flight earlier to Philadelhpia to make sure I won't miss my connection in Philly. So tomorrow will be my last day for real!!
