marked birds but are difficult to see as they feed among the 
dense foliage of the highest tree tops. 
They breed in the Missouri and Blue Valleys and may be 
commonly found in Swope Park during summer. 
One form of the song of this species is similar to that of the 
Cerulean Warbler but may be distinguished by a difference in 
the opening notes, which are more drawled in the song of the 
arula.

record for the lower Brush Creek region not far to the west. 
It is not seen in this county after the first week or ten days 
in September.
