Central Park New York City Birds

A variable small warbler notable for a yellow patch on the rump and often on the sides; plumage varies seasonally with streaked winter and brighter breeding forms. This species is one of the most reliable migrant warblers in Central Park during spring and fall, often found in mixed flocks in shrubs and the Ramble.

Key mark is the yellow rump visible in flight or when perched; also look for streaked flanks, thin bill and active foraging in branch tips. Note field variations—check rump and side patches when other warblers are present in mixed flocks.

Common Confusions

• Pine Warbler Setophaga pinus Pine warbler shows more olive upperparts and a less distinct yellow rump in some plumages and tends to forage more in pine needles rather than shrub tangles.
• Palm Warbler Setophaga palmarum Palm warbler has a rusty cap and habit of tail-bobbing and more rufous tones on the breast; yellow-rumped has a clearer rump patch and differing streak pattern.
• Yellow-throated Warbler Setophaga dominica Yellow-throated has a strong black-and-white face pattern and bright yellow throat; yellow-rumped warbler lacks that face pattern and throat coloration.
• Common Yellowthroat Geothlypis trichas Common yellowthroat is smaller with a plain olive back and male's black mask; yellow-rumped is more heavily streaked with a distinct yellow rump patch.
• Warbler hybrid Some hybrids show mixed traits; look for consistent rump patch and overall streaking pattern to confirm yellow-rumped.
