Anna's can be just plain nasty. When I lived in Newcastle (King Co) and had feeders up I saw one male kill at least two other hummers by knocking them to the ground and literally pummeling them to death with bill blows to the head. I later found 4 complete hummer skeletons within 20 feet of the feeders when I was weeding - serial killer of the bird world.

Tweets ? our first frosty morning (all the cars reported 32 degrees at
7:30, and there was a touch of frost here and there), but with the sun out,
things warmed up. It was at least 60 by the time we were done.
Rather quiet today ? we seem to be in a bit of a crease between summer birds and
winter birds ? we had only 2 species of duck, for example. But still some
interesting stuff.

Highlights: (FOF=First of Fall)

Cackling
Goose A couple
of small flocks early ? FOF
Red-necked Grebe Looked like 2 well out
on the lake ? FOF
Sharp-shinned Hawk At least 2
Cooper?s
Hawk At
least 2
Red-tailed Hawk At
least 3 pairs
Merlin
One over mansion ? landed a little after 7:30
Common Raven
One heard from start of boardwalk
Varied
Thrush
One near S end of Dog Meadow ? FOF
American
Pipit
At least 1 calling over Compost Piles early
Wh.-throated Sparrow At least 3!
Pine
Siskin
Our first largish flock ~25

After I got home, Houston Flores texted me to say there was a NORTHERN
HARRIER over the East Meadow.

Weirdest sight? near the park office, one male ANNA?S HUMMINGBIRD had
another Anna?s male pinned on his back on the ground. They stayed that way
for quite a while, watching us as we approached. I think we interrupted a
fight.

For the day, 54 species.
