Plegadis guarana. White-faced Glossy Ibis. 



Rare; two killed by Charles Eldredge at his ranch in 

 Chico Basin southeast of Colorado Springs, October 10, 1890. 



Mycteria americana. Wood Ibis. 



Rare; Aiken has three specimens in his private collec- 

 tion, all immature birds shot near Colorado Springs in August 

 about 25 years ago. 



Botaurus lentiginosus. Bittern. 



Rather uncommon from lack of suitable conditions. Ar- 

 rives in April, leaves in September and October. 



Ixobrychus exilis. Least Bittern. 



Rare, but two specimens being recorded from the County. 

 One of these was taken near Colorado Springs somewhere 

 about 1886; this was the first specimen of the species to be 

 recorded from Colorado. The other was taken at Colorado 

 Springs, June 18, 1907. This bird was found in a yard, 

 alive, but injured, probably from having flown against a tele- 

 graph or telephone wire. Both specimens are mounted and 

 in the Aiken Collection. 



Ardea herodias herodias. Great Blue Heron. 



Migrant, rather common, arriving early in April; the 

 earliest date is April 2, 1889. No breeding colonic? have ever 

 been known in the County. November 27, 1897, a young bird 

 was sent Aiken from Divide Station, on the Colorado Mid- 

 landn Railway, 9,200 feet altitude. An unusually late record 

 for the species. This locality is in Teller County. The latest 

 El Paso County date is November 2. 



Herodias egretta. Egret. 



The first instance known of the occurrence of this species
