Juvenile with scaly upperside and weaker breast color than seen on adults. The overall impression is always of a cold brownish colored bird quite distinct compared to other stints. The uniformly colored head, breast and throat is typical for the species whereas the other green-yellowish legged stints, Least Sandpiper and Long-toed Stints show more contrast often with a paler throat.
The black comma on the underwing coverts is a good field mark for the species as well.
Without having scrutinized the other peeps for variation, I would expect that the anchor shaped patterns on the wing coverts is a specific character of this species.
One bird present only. Probably my last for the year, mid September where most of the Africa bound shorebirds have gone through.
