Jocko,
Hope you get some replies on this, I think there may be some people around who could comment. (You could also try the ID forum...)
Sandflats
Had a great afternoon out on Sunday in Beidaihe - perfect weather, and a fairly good tide level.
At the entrance to the reservoir I was amused to see as many kingfisher photographers as kingfishers! There seemed to be a good number of Common Kingfishers about - I guess it was a successful nesting for them, otherwise I'm not sure if the 4-5 which seemed to be about would tolerate one another's presence in a relatively small section of stream. There was also distant views (for me) of a Black-capped Kingfisher, which I don't see too often. There were 5 tiny camouflage tent/hides with long lenses visible, as well and lots of natural and placed locations for kingfishers to perch. I love watching these birds and can't blame those so interested in capturing them on film. Two times they landed quite close to me for excellent views.
I also saw more clearly, what I'd seen on my last trip - a myna. It wasn't in "fine feather", but the lack of yellow around the eyes make me think it was Javan Myna - but I'm not sure which species is a common cage bird here.
A good number of Chinese Pond Herons in evidence on both sides of the highway (not to mention ubiquitous Great Egrets and Little Egrets). I guess the pond herons are just more visible now that nesting is through. Just saw one Little Grebe and two unidentified distant ducks on the reservoir itself. Thought that I saw a Bull-headed Shrike, which if correctly identified is a first for me.
On the sandflats' side I believe we had both Purple and Grey Herons (in addition to the other herons/egrets), though they were at such a distance that I can't be certain of telling the two types apart. Stonechats had arrived in numbers (none seen on a trip 5 days earlier) and were calling a good bit. There was a flock of perhaps 40+ Black-winged Stilts which did some nice formation flying. A few individual waders were distant and hard to identify (sandpiper? tringa?).
I was surprised to see what looked like a distant group of cormorants sitting on a shore with some gulls. I couldn't figure what else they might be, and when they decided to fly off around 6 pm, I felt more sure that they were Great Cormorants, including some light chested juveniles - total group was 15.
I then got better views of single Whimbrel, and Far Eastern Curlew (though I didn't see it flying). Two kinds of peeps were doing what we expect: peeping. With the help of Dongbei's recent pictures (and their large numbers which point to a common bird) I guess they were mostly Little-Ringed Plovers, and Red-necked Stints - definitely not in breeding colors, but the two species about the same size. I was happy to finally see a couple of White Wagtails which I've largely missed this summer; they were leucopsis, so I guess they were local not migratory.
I know there was more on the sandflats which I just didn't have the optics to see and work out, but it was a very pleasant day and lots of birds (and bird photographers on both sides of the road).
Working on my own here to figure out what's what, so feel free to comment if any of my deductions seem questionable.
