Visitors:
We had a nice group of over 20 visitors today, including someone all of the
way from Pittsburgh.
Weather:
The weather was pleasant from beginning to end. Even in the morning, when
the red sun arose above the horizon, we were warmer than during the warmest
part of yesterday. There was a light wind all day, which started from the
northwest, shifted to become westerly, and was southerly by the end of the
day. Barometric pressure dropped rapidly from 12 to 3.
Raptor Observations:
We had nice, long streams of Turkey Vultures flying over Gibraltar's
treeline, then to the north of us, between 10 and 11. When the wind shifted
to come from the west and then the south, the migrating TVs began passing
far to the north of us. During the last hour of counting, we spotted a
distant Golden Eagle taking a route similar to which the TVs took in the
morning. Several Bald Eagles were also moving today. The same number of
Northern Harriers (10) flew over today as flew over yesterday.
Non-raptor Observations:
A Red-breasted Nuthatch was singing this morning, as were several
White-throated Sparrows. Several groups of House Finches and American
Robins flew overhead, as did one group of 25 Blue Jays. At least 635
American Crows migrated over the site today, as did a Common Loon, a couple
Sandhill Cranes, and a couple Monarch butterflies. Huge groups of
Red-winged Blackbirds flew over this morning, with a count of at least
5,530 individuals.
Predictions:
Tomorrow is predicted to be cloudy with a northwest wind. This wind
direction is generally favorable for seeing raptors at our site.
