32 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 95 
nighthawk was recorded in Liberia on October 22 and was seen daily 
over the Plaza and the pastures adjacent to town until my departure. 
The ruby-throated hummingbird was common in certain areas. 
Among the flycatchers it was interesting to find the northern and 
southern races of the crested flycatcher in the same region and to 
obtain the yellow-bellied flycatcher. The wood pewees were still 
more intriguing, and at Liberia I shot specimens of the eastern, 
western, and Mexican forms, ranging together and not to be distin- 
guished except: in the hand. The scissor-tailed flycatcher appeared 
on October 24 and was found at times in flocks. In evening many 
came from the open country to sleep in the shade trees of Liberia. 
The barn swallow was another common species in the open areas, 
often in flocks. Bullock’s and Baltimore orioles were found together. 
In the woods and groves I collected yellow-throated and Philadelphia 
vireos and a fair variety of northern wood warblers, as well as the 
eastern summer tanager, the rose-breasted grosbeak, and the indigo 
and western painted buntings.
