March 9, 2022
Based on local birders reporting that the migration suddenly took hold with large numbers of waterfowl being seen, I managed a quick trip to Gedalou Reservoir and it payed off big.
One of my wife's friends, who lives near Gedalou, had called early that morning to tip me off to the lake being "black with ducks", but we weren't able to get out until afternoon. When we arrived at the west midpoint of the lake we turned south and by then it was not that impressive, but we quickly found large flocks of various waterfowl on the lake. Immediately upon arrival two flocks of
Common Coot of about 500 each were floating on the open water, mostly just resting.
Black-Headed Gull &
Mongolian Gull circled low overhead. Other than a few
Great Crested Grebe and
Goosander, nothing else was to be seen though and I was immediately disappointed thinking that our late arrival had caused us to miss the majority. Conditions were poor though, with a heavy haze which drastically reduced visibility, so I hopefully decided to circle the lake.
Heading back towards the north it didn't look good for the next three kilometers or so, but then, near the north end of the lake, binocular scans started to pick out several very large flocks obscured by the haze. As we got closer they were still only a brown mass, just obscured enough to be tantalizing, but even in the binoculars and with the 600mm lens, still not identifiable. I started rolling off shots on the camera, doing the best I could and hoping to be able to tease out some IDs later at home.
The haze improved a bit and I managed to get a little closer and between the two, I was finally able to start picking out some ID's.
A few
Gray Heron, closer into the shore, standing on the ice, were the first to clearly stand out, soon followed by some
Mallard that were a little closer to the main flocks.
Bean-Goose started to arrive, slowly circling down and had the good fortune effect of spooking the main flock into flight, which then just barely became identifiable as primarily at least 1000
Baikal Teal and another adjacent flock of maybe 1000
Falcated Duck.
Mixed in with both flocks were maybe 200
Eastern Spot-Billed Duck and smaller numbers of
Gadwall, Common Pochard, Northern Pintail, Tufted Duck, Scaly-sided Merganser and even a small group of
Cotton Pygmy-Goose. Confusing me at the time, as I rarely see any were another small group of
Eurasian Green-Winged Teal.
Common Merganser seemed to be restless as they flew back and forth across the scene. A scattering of
Great Crested Grebe even had made an early arrival.
A few
Great Cormorants also made an appearance.
It was only after circling the lake and actually having announced that we could leave that I spotted what was to me the jewel of the day. 20
Oriental Stork, loosely scattered about on the ice shelf!
Full list for the day below, though I now see that I somehow managed to split the Common Merganser into two groups. I'll get that corrected.
