Well I think this is a Louisiana Waterthrush due to the pinkish legs, but it could be a Northern Waterthrush, which is very similar. These migratory birds spend the winter in Central America or West Indies, so we were lucky to catch this one on on his way through Houston at the Edith L. Moore sanctuary (Houston Audubon). Also lucky that this rather elusive bird was pointed out by a regular birder.

Although its breast looks very much like that of a thrush, this is not actually a thrush, but a warbler.

This was taken at a fair distance from the opposite side of the creek, so the result is not bad at maximum stretch on my travel zoom Panasonix TZ200.
