November?

As we get into November, hopes for large numbers of birds are minimal, but the possibility of catching something like a Great Horned Owl has gone up, which is why I've found myself at the hawk trapping blind as the sun is setting with hopes of luring in one of these massive birds before opening up the nets for the night.  Though there have been no signs of GHOWs yet, I did catch a late Goshawk last night, just as it was getting dark.  Though the hawk trappers have caught a number of adults already, I'm usually asleep for them, so this was my first adult of the year!

This is a second year female

The brown feathers are retained juvenile feathers from last year

As with other Accipiters, their eye color changes from yellow to orange to red as they get older.  The low lighting did not help any of these pictures, but the blur seen here is due to some excessive screaming by this bird.

Gos release

Ok night of owl banding, with 32 Saw-whets, 5 LEOW and 1 Barred.  Probably the coldest night so far, possible getting down into the high teens.

Diurnal for a day

The last couple of days have brought much colder weather and high winds, giving me two nights off and a chance to interact with the living. Or at least the diurnal birds. I got to see two HY male Goshawks caught withing two minutes of each other yesterday at Frank's blind. IMG_1200_2

Boredom Trapping

I did see another hawk!

I also did some more chickadee catching. I've caught six of them with different bands. At some point I'll look them up and see where they're from (probably here).

This one had a couple of white feathers growing on its head. Freak.

ADGOS

Despite missing the first adult goshawk we caught this year, I had my chance today. This is an after second year female. As you can see the plumage difference between the immature and the adult birds is much more dramatic than in most of the other species we catch.

So Far

So far today we have two gos, an RT, and a little male shin. In total we have around 1750 birds.

This short video is a good example of how quick accipiters are. An RT would not be able to take off like this.

Lil guy

Last night was our first night of zero hours since we started running them... Today however I caught two goshawks, one of which had the smallest wing cord measurement Fud has ever seen (though it did not weight the least).

The little guy:

Snow?

The first snow of the year landed us about two inches at the station. Last night there were record low pressures for the area, and if it had been colder for the past two days we would surely have been snowed in big time.

I shoveled out the bownets and got the ice off of the mist nets by 9:30 (after the rain had stopped). Not much seen today, but we did get one goshawk, which was on the starling before we even saw it.

Comparison

I don't have much new to show, but I thought I'd put up a comparison post. A lot of these pictures are repeats but I separated them by genus and labeled them by age and sex if I knew it. We still haven't caught some varieties (like an adult male harrier) and I'm missing pictures of a few (like a female kestrel), but I thought this would give a good look at the hawks we have been catching, with side-by-side comparisons to show some differences.
