YELLOW-BELLIED FLYCATCHER 



the small differences in color that exist are 

 obscured. 



37. Empidonax flaviventris (Baird) 

 Yellow-bellied Flycatcher 



Sexes alike. Length, 120 mm. (4.75 in.) ; tail, 

 51 mm. (2.00 in.). Dull olive green above; a 

 ring of yellowish white around eye ; two wing bars 

 of pale yellow; below pale yellowish tinged with 

 olive on chin and throat, the chest and sides of 

 breast more olive, shading to pale but clearer 

 yellow on rest of underparts. 



A migrant from the eastern United States. 

 Recorded from Lion Hill and Panama City. 

 Those I have seen in the north were shy and 

 silent, frequenting the lower branches of deep 

 coniferous woods. Distinguishable from others 

 of the genus by the uniform clear (not buffy) 

 yellow of the under parts and its small size, and 

 from species of Rhynchocydus by its much 

 smaller, straighter bill and smaller head. 



38. Empidonax virescens (Vieillot) 



Acadian Flycatcher 



Sexes alike. Length, 131 mm. (5.15 in.); tail, 

 58 mm. (2.30 in.). Above dark olive green with 

 a rim of yellowish white around the eye and two 

 wing bars of the same; below white tinged with 

 yellowish olive on chest and with yellow on sides 

 and abdomen.
