Northern Waterthrush (Parkesia noveboracensis)

The Northern Waterthrush is one of springtime's warbler delights here in New York City. You can find him bobbing his tail by your local babbling brook. Of course, he's migratory and will only be seen in these parts for a few weeks each year en route between the tropics and his summer home in Northern Canada.

I saw this individual by Triplets Bridge. I could (reasonably confidently) distinguish this Northern Waterthrush from the very-similar Louisiana Waterthrush with two field marks: 1) the chest striping that continues up to the throat, and 2) the slight yellow tint to the supercilium (that's the plumage line between the beak and the back of the head).
