I went to Monument Knob (Washington Mon St Pk) for the first time this =
season today (10/16/99). After the fog lifted about 12:30 there was a =
pretty steady stream of hawks, almost all Sharp-shins, with a few =
Harriers and Red-tails. The highlight, of course, was a Golden Eagle =
about 1:30. It was at medium distance and easily identifiable by its =
broad white band at the base of the tail and its golden head. It did not =
have obvious white wing patches. It's the first one I've seen there in =
maybe about ten visits over the years at the appropriate season. The =
main counter there said it was the first of this season. Winds were =
southeasterly 5-10+ mph. Most of the hawks flew by the east side of the =
tower, but the Golden was on the west side.

Earlier today I had an unusually good look at a Blue-headed Vireo. I =
remember that Jim Stasz was asking us to try to identify them by =
sub-species as Blue-headed Vireo (Vireo solitarius solitarius) vs. =
Mountain Vireo (Vireo solitarius alticola). For what it's worth, it was =
clearly the Mountain sub-species. The green on the back was very dark =
and grayish, and the yellow was limited to the lower flanks. It's rare =
to get enough of a look at one of these guys to see the difference. If I =
had a lesser look, I would have had the impression that the whole back =
was just-plain gray. (The wing-bars were yellow, so don't go rushing for =
a Plumbeous Vireo.) This was at Powell's Run Rd in W Baltimore Co just =
north of Marriotsville Rd.

I believe the few that I saw last spring locally appeared to be the =
greener backed regular B-h Vireo.
