March 12, 2019 RongXing Reservoir
Seven hours made for a full day birding yesterday. The group talking about using my efforts in their environmental education efforts apparently are serious about it. Clear blue skies appeared in the morning instead of the clouds predicted so my wife made a phone call and by 9:00 a car and driver showed up. I decided to check out RongXing Reservoir as I had found nesting Black-Winged Stilt there last summer but had not been able to check on migration there. The villages around the lake have now been fully abandoned and there is now a boardwalk extending well out into the surrounding marsh. Should be good for Black-Winged Stilt, Herons and Egrets in the summer. There was very little human activity, with only three or four other vehicles circling the lake.
The lake was dotted with large and small mixed flocks of ducks, primarily Common Pochard. Mixed were Tufted Duck, Common Coot & a few Ferruginous Duck. One odd duck accidentally captured in a photo led to some discussion on the ID forum and it seems to be most likely a hybrid of Bayer's Pochard. Too bad it had to be an unknown hybrid as that would have made for a nice lifer.
One lifer that I did collect was a small number of Common Goldeneye that were hanging around with some Tufted Duck.
Along the shoreline were the earliest Great Crested Grebe that I have recorded so far. A small group of Gadwall was noted in the binoculars and Smew were scattered about. A few Herring Gulls were scattered about. A couple of flights of Swan Goose circled the lake but then went back to the surrounding agricultural land. The same for one small flight of Bean Goose just a bit too far out to differentiate Tundra/Taiga. A flight of Great Cormorant made a low pass over the lake, skimming the wave tops, but also decided not to land.
Several birds down in the wetlands surrounding the lake were several small brown bird types but the lake action kept me from investigating those closer. Vinous-Throated Parrotbill were a likely candidate, but I couldn't say for sure. Chinese Penduline Tit were also a possibility as we did find a couple of old Penduline Tit nests. The mystery bird that I have been hearing but not seeing for several weeks, made its appearance. They are always in reed marsh and with a tremulous, downward pitched call. I would guess at a wader of some sort, but that is only guessing.
After completing a 10km circuit of the lake the rest of the party, being Chinese, couldn't conceive of missing lunch, so we moved over to the fishing port of Erjiegou for seafood. I pointed out that we were burning daylight and losing the light as clouds were moving in on the horizon, but to no avail.
After lunch, I did check out the tidal mudflats at Erjiegou as there was almost a 12 meter tide swing. The mudflats were fully exposed but it is still a bit too early for the usual crowd there. Literally the only thing we found were two Herring Gull.
