BIRDS OF KANSAS, 



BY I'KOF. FRANK H. SNOW, OF THE STATE UNIVERSITY. 



Since the publication of my catalogue of the birds of Kansas in the transactions of the 

 Kansas Academy of Science for 1872, the following additional species have been ob- 

 served, viz: 



1. CJolaptes Mexicanus — Red-Shafted Flicker. A large flock of this species remained 

 for about two weeks in the timber along the Kansas river within a mile of Lawrence, in 

 December, 1872. A specimen was obtained for the University cabinet by Nelson J. Ste- 

 phens. A single specimen was also seen and identified by tlie writer in the same locality, 

 March 26, 1874. The occurrence of this species here is worthy of notice, from the fact 

 that the Hybrid Woodpecker (C hybridus) had previou.sly been taken in several instancse 

 in this vicinity, the latter form being generally supposed to be a cross between the com- 

 mon Yellow-Shafted Flicker (C auratus) and this newly discovered Red-Shafted Flicker. 

 An interesting fact in this connection was the capture (April 12, 1871, by Eugene Ken- 

 nedy, a Universitiy student) of a pair of Woodpeckers, with a nest of eggs containing 

 young birds, the male parent being an albino specimen of C. hybridus and the female a 

 specimen in ordinary plumage, of C. auratus.
