The Ashy-throated Warbler has a distinctive ashy-gray throat, while the Yellow-bellied Warbler features a bright yellow belly. Both species have a prominent supercilium, but their overall coloration and habitat preferences can aid in identification.

Identification tips

• Throat color: Look for the ashy-gray throat of the Ashy-throated Warbler versus the bright yellow belly of the Yellow-bellied Warbler.
