TANAGRID^. 



Pyranga estiva, (L.) v. — Summer Redbird. 



Observed along Wolf Creek and the Canadian, always in pairs; too 

 sby to permit me to secure specimens. 



HIKUNDmiD^. 



HiRUNDO HORREORUM, Barton. — Barn Sivalloic. 



Frequenting settlements in Indian Territory; not as common as P. 

 lunlfrons. 



Petrochelidon lunifrons, (Say) Cab. — Cliff or Eave Swallow. 



A species very abundant in the caiion region of Red Eiver and its trib- 

 utaries. In descending a sidecaSon leading down to the river, where the 

 water only poured down in the rainy season, dashing over cliffs a hun- 

 dred and at times three hundred feet high, I found occasionally the 

 under side of the overhanging rocks covered with the mud nests of this 

 species, curiously wrought and bottle-shaped as they often are. Some 

 nests even then (the middle of May) contained young, whilst most of 

 the other birds met with had scarcely as yet completed building. Also 

 found building at ranches on the prairie near the streams. 



CoTYLE RiPARTA, (L.) Boic. — Ba7ik Swallow or Sand Martin. 



Not uncommon along parts of Eed River, where occasionally banks, 

 of the most glaring red clay rise up perpendicularly for a hundred feet 

 from the dry alkali bed below. 



VIREONID^. 



ViREO GiLVUS, (V.) Bp.r- WarUing Yireo. 



This exquisite little songster was frequently met with in the groves 

 and thickets, except along alkali waters, where none were heard or 

 observed. Very many specimens might have been obtained if desired, 

 as they appeared to court familiarity, when no harm was suspected, in 

 order to have their songs heard by all they could reach. 



ViREO SOLITARIUS, (Wils.) Y. — Blue-lwaded or Solitary Vireo. 

 Occasionally observed, but not as frequent as V. gilvus.
