Spring migration at San Tin

San Tin is a maze of fishponds, rather like an anarchic version of the nearby Mai Po Nature Reserve. In spring the ponds attract marsh terns, and today a flock of Whiskered Terns was busy fishing.
The fish farmers have apparently been persuaded to leave at least one pond half-drained of water to serve as a feeding site for passing shorebirds. In particular all four species of stint pass through in spring. Today saw a flock of Red-necked Stints, the most numerous of these species on the East Asian-Australasian Flyway; a few Long-toed Stints, which indeed have unusually long toes when one gets close enough to see them; and one or two Little Stints. The diminutive stints do not form a genus of their own, and one of their larger relatives, the Sharp-tailed Sandpiper, is extremely similar in plumage to the Long-toed Stint. A reliable way to distinguish the two is to compare the size to "control" birds such as the resident Wood Sandpipers, which are about the size of the Sharp-tailed and much larger than the Long-toed Stint. As for the Little and Red-necked Stints, they can be difficult to distinguish unless the latter is in red-necked breeding plumage. By catching the two side by side one can spot subtle differences such as the longer legs (black in both species) and longer, more finely pointed bill of the Little Stint.
Other passage migrants present recently have included Curlew Sandpipers, Kentish and Pacific Golden Plovers, Oriental Pratincoles and Eastern Yellow Wagtails.

Hi, Stephen, may I know that is it possible to drive to the fish ponds in San Tin?

Hi, yes one can drive in, and this avoids having to walk past dogs which are not always friendly. The fishpond owners/operators don't seem to mind, but the roads are rough and the route is quite complicated. Ton Yeh showed me the way. If you take the San Tin Highway from Mai Po (Tam Kon Chau Road) the entrance is the first substantial one on your left. There is a large sign saying 'Yokohama' at the entrance, which looks like the way into an industrial site. It is, but before the entrance to the industrial site you can turn left on either of two very rough roads leading to the fishponds. The second of these, the very last possible left turn before the industrial gateway, leads to a fork where you can turn right over a concrete bridge to reach the most interesting ponds. You can then drive around until you find the drained pond (mostly covered with caked mud, with a large barn on the northwest side) and park at the side of the road. Hope this helps!

Thank you for your sharing. Hope I could find the way to the fish ponds someday.
