Tips for using Browse:

Browsing is a valuable way to learn about birds, however it is a brute force approach and not designed for identification. A more sophisticated approach to finding a bird with specific field marks is to use the Step by Step Search. You can also try the Wizard to find a bird, which uses a question and answer approach, but again it does not give you the flexibility of the Step by Step Search.

Wilson's Warbler
Wilson's Warbler: Small warbler with olive-green upperparts, bright yellow face and underparts, distinct black cap. It has a long, olive-brown tail which it moves up and down, or in a circular fashion, as it searches for food. It is more common in the West than in the East. Legs and feet are pink.
Worm-eating Warbler
Worm-eating Warbler: Medium-sized, ground nesting warbler with olive-gray upperparts and pale yellow underparts. Yellow head has black crown stripes and eye-lines. As its name suggests, it eats a steady diet of moth caterpillars and worms. It usually forages in understory vegetation and dead leaves.
