EMPIDONAX ACADICUS, ACADIAN FLYCATCHER. 249 



the latter. The usual eastern type was not met with west of Eastern 

 Kansas, the western form being the only one seen in Colonido. The 

 latter was especially ireqnent near Fairplay, in South Park, where it 

 was breeding, but all the nests obtained contained half-grown yonng." 

 The eggs are very similar to those of C. virem. 



The following has been obligingly coinmnnicated by Mr. Tiippe: 

 "This bird arrives in Bergen's Park, Colorado, in the latter part of 

 May, and soon becomes abundant, extending its range up to over 

 10,600 feet, and perhaps as high as timber-line. It breeds from about 

 7,000 feet upward. The nest is planted in the fork of a tree and 

 resembles that of Emiridonax mimimis, being quite different from that 

 of the Eastern Wood Pewee; the eggs, however, are entirely similar. 

 The young are hatched late in June, and only one brood is raised. It 

 is one of the first birds to leave in autumn, departing about the middle 

 of August. In notes and habits it is very different from C. virens. In- 

 stead of haunting the thickest woods, it roams over the open country, 

 shunning the deep shade of the forests, and acting in all respects like 

 Sayornis fuscus ; while its notes are far harsher and quicker than the 

 slow, melancholy plaint of the Eastern Wood Pewee, and only faintly 

 resemble it. Tlie two varieties, in fact, are as well marked as any that 

 are supposed to belong to the same species of this family."

The present is the most distinct and easily recognized of the four 

 species of the genus inhabiting the Eastern States. Nevertheless, it 

 has been frecjuently conlouniled with others, notably by New lOiigland 

 writers, many or most of whose citations really refer to minimus or
