Description:

Yellow-bellied Kingbird (Couch's/Tropical type); pale gray head with dark auricular patch going through eye. Greenish-gray mantle; bright yellow underparts from undertail coverts to upper breast; pale grayish-white throat and a darker, diffuse band between yellow breast and pale throat. Brown, deeply notched tail without white outer rectrices. Very long, black bill. 

Voice:

Called twice while interacting with a Scissor-tailed Flycatcher. The call was a soft trill or twitter.

Similar species:

The extent of the yellow in the breast and brown, notched tail without white outer recttrices eliminate Western Kingbird. The long bill points to Tropical as opposed to Couch\'s. The call distingushes the bird from Couch\'s and makes it a Tropical.

Stills from the video accompany this report. Video with the call will be submitted to the LBRC.

Previous experience with this species: 

Iíve seen several Couch's and Couch's/Tropicals in LA, but this is the first definitive Tropical Iíve had in LA.
