Definition of yellow-rumped warbler
- Immature yellow-rumped warblers are gray with many streaks. However, they are missing the classic yellow rump found on adults.

- An early spring migrant, yellowrumps are on the move in large flocks in early April, making the species the first warbler to move in numbers.
