V ° L 1920 XVI1 ] Lincoln, Birds of the Clear Creek District, Colo. 69 



of this variety was secured on June 4, 1911, the second record for the State, 

 and another on August 6, 1911. (Auk, Vol. XXX, p. 112). At the time 

 Empidonaces were common and it is not improbable that persistent col- 

 lecting of the genus would have revealed still other examples. 



Empidonax minimus. Least Flycatcher. — Rare. Only noted on 

 migration. I secured a pair August 8, 1911, and Mr. Rett's collection 

 contains one taken August 30, 1914. 



Empidonax wrighti. Wright's Flycatcher. — Rare or accidental. 

 Mr. Rett's collection includes a specimen of this species taken May 19, 

 1918 (Coll. E. R. No. 291). This probably marks the eastern limits of the 

 species. 



Otocoris a. leucolsema. Desert Horned Lark.— Winter resident, 

 abundant. 



Otocoris a. enthymia. Saskatchewan Horned Lark. — About 

 thirty per cent of the specimens secured in the winter are referable to this 

 variety. Although not recognized by the A. O. U. Committee, my speci- 

 mens seem to uphold its characters as their differences from leucolcema are 

 quite pronounced and agree with the characters of no other race. 



Pica p. hudsonia. Magpie. — Plentiful resident. A feature of the 

 landscape that would be missed were they exterminated as has been advo- 

 cated. One cannot but admire them despite their rascality. Complete 

 sets of eggs found March 31. 



Cya,nocitta s. diademata. Long-crested Jay. — Common winter 

 resident in the valley. Resident in the foothills. 



Aphelocoma woodhousei. Woodhouse's Jay. — Winter resident; 

 common some years, and entirely absent at others. Generally, they are 

 more readily approached than C. s. diademata. 



Corvus b. brachyrhynchos. Crow. — Not common. One noted 

 November 19, 1910. Dr. W. H. Bergtold has recently shown (Auk, 

 XXXVI, pp. 198-204) that the Crows of the eastern portion of Colorado 

 are principally of this subspecies. The occasional examples seen in the 

 Clear Creek District are therefore, so referred. No specimens have been 

 taken. 



Cyanocephalus cyanocephalus. Pinon Jay. — I am indebted to 

 Mr. Rett for the opportunity to include this bird. He tells me that on 

 October 24, 1915, a flock of about 50 individuals was seen, two being se- 

 cured. They were subsequently noted weekly until November 25, when he 

 again secured specimens. They had not been observed in the valley 

 previously, nor since, to my knowledge. 



Dolichonyx oryzivorus. Bobolink. — Rare. The only record is a 

 specimen in the moult, taken August 5, 1911 (Coll. F. C. L. No. 248). 



Molothrus a. ater. Cowbird. — Summer resident, common. Red 

 wings, Yellow-heads and Yellow-throats seem to be the species most 

 generally imposed upon in this region. 



Xanthocephalus xanthocephalus. Yellow-headed Blackbird. —
