Tyrannus tyrannus. Kingbird. — Not uncommon during migration in 

 northwestern Colorado. Steamboat Springs. Craig and Lay (Warren). 

 Near Rifle, near Boggs Crossing, Meeker, and Edwards's Sheep Camp in 

 Routt County (Cary). One was seen in June at Navajo Springs, Monte- 

 zuma County (Oilman). This is apparently the most southwestern record 

 in the United States. 



Tyrannus verticalis. Arkansas Kingbird. — The average date of 

 arrival at Yuma is May 6, and of departure September 16; the extremes 

 are April 30. 1905. and September 23, 1904 (Patten). Breeds in Baca 

 County (Warren) — the most southeastern breeding record in Colorado. 



Myiarchus cinerascens. Ash-throated Flycatcher.— One in 1907 at 

 Douglas Spring near Dotsero (Warren). A great extension eastward of 

 the known range results from the capture of one May 25 1905, at Gaume's 

 Ranch, Baca County (Warren). 



Myiochanes virens. Wood Pewee. — The one taken May 12, 1905, near 

 Springfield, gives the first record for Colorado (Warren). 



Otocoris alpestris leucolsema. Desert Horned Lark. — The statement 

 is made in the original bulletin that "the literature of the Horned Larks in 

 Colorado is more mixed than that of any other bird; alpestris, cornuta, 

 occidentalis and chrysolcema have all been recorded for the State, but 

 according to present ideas only leucolcema and arenicola really occur in 

 Colorado." Changes in nomenclature during the past twelve years have 

 made the matter still more complex. It has been found that arenicola is a 

 synonym of leueohema and must be dropped, while two new names prati- 

 cola and hoyti have to be taken into consideration. 



According to present ideas all the breeding birds and almost all of the 

 winter birds, in spite of the wide variation in color, are referable to leuco- 

 hnim. 



[Otocoris alpestris arenicola. Desert Horned Lark. — This name 

 is dropped from the Colorado list as being a synonym of leueohema.] 



Otocoris alpestris praticola. Prairie Horned Lark. — Accidental, 

 once at Denver (Oberholser). First and only record for Colorado. 



[Otocoris alpestris hoyti. Hoyt's Horned Lark. — Breeds near the 

 Arctic Circle and comes south in winter to the northern United States. It 

 has been taken south to Camp Floyd, Utah, and to Emporia. Kans., and 

 hence undoubtedly occurs in winter on the plains of northeastern Colorado.] 



Cyanocitta cristata. Blue Jay. — It seems strange in view of the 

 commonness of the bird in Wray County, that it should have been so 

 lately added to the Colorado list. The number of 'The Auk' for January, 

 1905, contains records by Smith and Henderson of its occurrence at Wray 

 and at Yuma. The species is now known to occur locally along the whole 

 eastern edge of the state, from Holly to Julesburg; it is a common breeder 

 at Wray and wintered there 1907-8; it ranges west to Yuma, where it was 

 first seen in 1903, and has been noted in summer from May 19 to November 

 1. but is not yet known to remain through the winter. It has also been 

 recorded west to Limon (Felger) and to Springfield (Alexander). A
