238 UNIVERSITY OF COLORADO STUDIES 



588a. Pipilo maculatus montanus — Mountain Towhee. 



Abundant summer resident from base of foothills to about 9,000 feet. 

 591. Pipilo fuscus mesoleucus — Canyon Towhee. 



One taken at Boulder by Howard S. Reed (H. G. Smithy, March 17, 1895. 

 ■592.1. Oreospiza chlorura — Green-tailed Towhee. 



Common summer resident from plains to timberline. Gale took two nests at 10,000 

 feet on May 19, 1888, and June 30, 1890, respectively. 



595. Zamelodia ludoviciana — Rose-breasted Grosbeak. 

 But one record, nesting at Longmont in 1894 (Cooke). 



596. Zamelodia melanocephala — Black-headed Grosbeak. 



Not uncommon summer resident of plains and lower mountains. Gale took seven 

 nests in May and June and recorded it up to 8,000 feet. 



597a Guiraca caerulea lazula — Western Blue Grosbeak. 



Felger took one specimen in 1903, and Dille took two and reported others at base of 

 foothills near Altona in June, 1902. I believe these are the most northerly records in 

 Colorado. 



599. Passerina amoena — Lazuli Bunting. 



Common summer resident of plains and foothills. 



604. Spiza americana — Dickcissel. 



Rare. One in University collection taken at Boulder in 1903 by Bragg. 



605. Calamospiza melanocorys — Lark Bunting. 



Abundant summer resident of plains. Gale says also of the mountains. 



607. Piranga ludoviciana — Louisiana Tanager. 



Not uncommon summer resident of mountains, common on plains during migration. 



612. Petrochelidon lunifrons — Cliff Swallow. 

 Abundant summer resident of mountains and plains. 



613. Hirundo erythrogastra — Barn Swallow. 



Abundant summer resident of plains, less abundant in mountains. I have seen them 

 up to 9,000 feet or more. 



614. Iridoprocne bicolor — Tree Swallow. 



Gale found it nesting on Jim Creek, June 12, 1887, and June 13, 1888, and at 10,000 

 feet near Ward on May 31, 1887. 



615. Tachycineta thalassina lepida — Violet-green Swallow. 



Common summer resident at Boulder and on near-by foothills, less common at other 

 points to the northward. Gale found it nesting in the mountains but gives no data. 



[616. Riparia riparia — Bank Swallow. 



Gale mentions this species in his notes, but careful consideration of what he says 

 leaves it doubtful as to whether this is what he saw.] 



618. Bombycilla garrula — Bohemian Waxwing. 



Irregular winter visitor of mountains and plains, erratic in its movements. A few at 

 Boulder nearly every winter. On February 13, 1905, I saw 150 in one flock.
