Weather: With a high barometer reading of 30.3â the sky for the beginning of the watch was clear of any obstructions, at least in the form of clouds, to the viewing of raptors. The avian flak was there in the form of numerous swallows that were concentrated into a small area and always seemed to be where the migrating birds were in the early hours. The wind took its time; building up gradually and eventually shifting to a more southerly direction that in the end affected the flight. The later hours saw the birds pushed more to the north in the haze that results when the wind blows off the lake. The barometer dropped about a tenth later in the day and the sky began to fill with cloud. At times temporary wandering planes of thin solid cloud backed by blue but growing into a solid mass with a dark gray bottom daubed with streaks of steel blue that looked vaguely ominous. Raptor Observations: >From a slow beginning the day got to the next level and the next level after that. At times the flight lines were many and varied. It required a lot of concentration to track all the birds soaring and drifting on the wind that was increasing in strength. Fortunately, I am surrounded by experts who carry the heavy load. Thirty five hundred and twelve turkey vultures kettled and streamed by, starting strong early and tapering off till the last hour when they rushed for the exits again. Four bald eagles were counted on a day in which eagles, with all the local contingent present and accounted for, seemed to fill the sky and also the âeagle tree with four young birds sitting there at once for a good while. Twenty two harriers rocked their way through. Sharp-shins built to a peak and then tapered off again with seventy of one hundred fifty one total for the day coming in one hour. Cooperâs hawks were on the move with six registered. The falcons were a small part of the flight today with only two kestrels (they seem to be avoiding our site this year), five merlins, and two peregrines noted. This was a day for buteos to move, finding a corridor of energy to their liking, they came early and often after the winds picked up. Two hundred forty nine red-tailed hawks (including one dark morph) soared through riding the turbulence of the winds kicked up by the trees and houses below them. They were joined by sixty one red-shoulders and one, our first of the season, light morph rough-legged hawk. We caught two golden eagles trying to sneak by in a long glide but their white tails gave them away. Today they came around midday so the four oâclock golden eagle rule is apparently not written in stone. Non-raptor Observations: The talk of the day at the watch was a gathering of great egrets (30-40) in one of the marshes that all visitors must drive by. The white statuettes were hard to ignore. The SW winds had blown the water levels down and egrets love to have their targets concentrated in shallow water. This is ideal shorebird habitat and there were a few greater yellowlegs in attendance there too. We saw two of my favorite camera subjects, the Bonaparteâs gull and the Forsterâs terns come in to fish nearby for a change. The American white pelicans were seen flying in formation over the lake. One common loon was seen flying by to a destination further upriver. The swallows were plentiful this morning as they filled the sky at times with hundreds of them present. Predictions: Your expectations for rain tomorrow depends which computer model you believe. No one knows for sure. The winds will stay strong from the S but the barometer will be heading down so that does not bode well although it should stay around thirty inches. Skies should stay very cloudy; temps will stay in the fifties. There will be a varying threat of rain through the day although it should be light if it does occur. Good sharpie weather. ======================================================================== Report submitted by Kevin Georg ([email protected]) Detroit River Hawk Watch information may be found at: http://www.detroitriverhawkwatch.org More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=285 -- Ontbirds and Birdnews are moderated email Listservs provided by the Ontario Field Ornithologists (OFO) as a service to all birders in Ontario.
