Waders in Deep Bay

Grey-tailed tattler

I got up around 6AM this morning to get ready and head out to my usual spot on the shore of Deep Bay (Hong Kong side), knowing full well that I’d have to wait a bit for the tide to go out no matter how early I got there. I find that I have the best luck during the outgoing tide at this spot, but only for a few hours. There’s a crucial point shortly after high tide where the waders will come in fairly close to shore as the shore expands. After about 2 hours or so, however, the shoreline, along with the waders, is too far out to really expect good shots, so it’s important to be timely.

Unfortunately I arrived far too early and had to wait about 2 hours for the tide to get low enough for any waders to even attempt to start bopping around on the sandbar. Normally this would be fine, and I would have just come later, but the other major factor was heat, which was why I was keen on meeting the tide exactly. By midday we had temperatures of 34C, which, aside from being unpleasant to the point of dangerous in the wrong place, forces a photographer to reckon with image distortion caused by heatwaves.

In my experience, heatwaves are strongest close to the ground, which, unfortunately, is where you want to be for waders. However, while some of my shots were noticeably affected, others happened to turn out okay. Perhaps because the beach was so freshly uncovered by the tide, the ground was still cool enough to not throw off very much heat. Either way I’m happy that not all of my shots were ruined by heatwaves.

As for the birds, I saw the usual greater sand plovers, though not in very great numbers; I only counted 5. With them was a lone lesser sand plover, hugging the shoreline, as well as 3 kentish plovers. The smaller plovers stayed very near the shoreline and well away from me, while the greater sands were more characteristically fearless.

One of the greater sand plovers was very diligently grooming itself in the same spot for quite some time, fluffing itself up even. (I think this one is a juvenile due to the more varied patterning on the wings.)

Most entertaining, however, were the 22 grey-tailed tattlers scurrying about the mudflat, along with 4 very grumpy Eurasian whimbrels. I’ve seen whimbrels at this spot before, but they didn’t behave like the ones I saw today. These ones were clearly interested in feeding at this spot, and had even waited on the beach with me for the tide to go out for some time until one of the locals walked by.

When out on the mudflats, the whimbrels were very territorial and would routinely chase each other off, shouting alarm calls at each other, flying over to the next beach and returning, chasing one-another on foot–it seemed like they just couldn’t stand each other’s company, totally unlike the 8 whimbrels I saw weeks ago who all stayed very close to one another while resting and foraging. If I were to guess, I might think that the group of 8 were too tired from a long journey to bother one another, while the visitors here are more well-established and have their preferences.

Equally entertaining were the tattlers scurrying around trying to stay out of the way of the bickering whimbrels. In one photo I managed to catch 11 of them (count and double-check) keeping cool under the mangroves while the whimbrels foraged first.

One cheeky bird even took a bath! If you ever wondered how tattlers take baths, well, this is it.

This is probably the closest I’ve gotten to a tattler before, and maybe ever will. The last time I was almost this close, the shot was ruined by heat waves. This time though the water in between us definitely kept things cool enough to not throw off any heat, so that was some very good luck indeed.

Otherwise there I didn’t notice anything else in terms of waders aside from 2 shy common sanppipers. There were no little ringed plovers to be found, nor did I see the common greenshank from last time. Hopefully the next time the tide swings back around to coincide with earlier hours, some other migrants will arrive.
