One brave visitor came today. Johannes braved I-94 and the weather but
unfortunately his thermal armour was found wanting in relatively short

As Super Chicken used to remind Fred the Friendly Lion, "You knew the job
was dangerous when you took it." Winter payed us an visit yesterday and the
cold temperatures (20's F) and snow stuck around today. NW winds cleared
the sky early in the day and probed for any chinks in our thermal armour.
The clear bright blue sky began to fill with cumulus clouds in the
afternoon changing the look of the birds as they were more frequently in
shaded areas under clouds. Barometer stayed at 30.3" for most of the day.

Raptor Observations:
The northerly winds suited the raptors today and they responded by moving.
100 turkey vultures came in small groups but their numbers were surpassed
by the red-tailed hawks totaling 129. Red-shoulders numbered 31. Perhaps we
might have had more of the buteos but the wind was a little too fresh and
persistent. 9 harriers flew by today along with 8 sharp-shins. 1 bald eagle
was seen high overhead heading to warmer climes.

Non-raptor Observations:
The brisk arctic air seemed to encourage the ducks and swans to take to the
skies in small units today. Another type of avian flack that we don't
normally encounter. Some horned larks were seen moving by in small flocks.
One sandhill crane was observed. Our "gull-friend", the injured herring
gull that has adopted us was seen flying to the middle of the slip today.
It's primary flight feathers seem to be growing back to some degree.

Another cold day in the trenches tomorrow. Not as promising as today was as
the winds will switch back to SW and increase during the day. The good
thing is that the watchers are generally sheltered from this wind but the
bad thing is the wind is not favorable to our site. It shouldn't be too
strong though so perhaps the buteo flight will continue to some degree.
Barometer will peak midday and then fall but not drastically.
