Weather:
no precipitation; 100% clouds; 13 C; R.H. 72-76%; 30.15 mm Hg avg.; wind
ENE to E to ESE to E to ENE @ 4-7 mph.
Observations:
Movement was slow. Birds not looking crisp with gray sky. Contrast poor.
Red-tails and vultures generally moved north along the eastern woods and
followed northern tree line. At times vultures were 'thick' at limit of 20
power scope north of site. They were even north of the highway 20 at
Malden Centre. A small kettle of 8 RT crossed over the tower as did a late
Rough-legged Hawk. Some birds were at the limit of vision overhead.
One Dark Morph Red-tail was counted. It passed north and near the tower.
Many of the distant Rough-legged Hawks would stop in forward flight and
turn to face eastward and hover for 30 seconds and then wheel to the west
and continue for 50-100 feet and again turn eastward, hover, and wheel
westward again. This behavior might consist of 3-4 hovering events by a
single bird.
Observers were greeted by the remains of a Pied-billed Grebe at the top of
the tower floor and railing. Perhaps the leftovers of a late dinning
Peregrine Falcon of yesterday. Wing feathers still attached to their bones
and one foot were the only clues to the identity of this meal.
One large flock of 40 Rusty Blackbirds seen for 10-15 minutes perched in
several small trees south and eye-level to the tower. Some were calling
their 'rusty hinge' song.
