Wyoming Birds. 57 



494. Dolichonyx oryzivorus: Bobolink. 



Fairly common summer resident in suitable portions of the 

 state. Jewett found it to be common at Afton. 



495. Molothrus ater ater: Cowbird. 



Exceedingly common summer resident over the entire state 

 at the lower altitudes. 



497. Xanthocephalus xanthocephalus: Yellow-headed Blackbird. 



Abundant summer resident about the marshes of the lower 

 altitudes throughout the entire state. 



498. Agelaius phoeniceus phoeniceus: Red-winged Blackbird. 



Knight reported only the Red-wing, and many of the recent 

 observers record it, from the eastern portion of the state. 

 Blackwelder reports it from the Teton region. It is prob- 

 able that some of the records should belong to some of the 

 succeeding forms. 



498d. Agelaius fhoeniceus fortis: Thick-billed Redwing. 



At the lower and middle altitudes of the entire state Red- 

 wings are found, and it is probable that most of the records 

 should be for this species. It has been reported by Richard, 

 Peabody, Buck, Clearwaters, and Walker. Specimens taken 

 near Laramie are very evidently of this species. 



501 — 1. fturnella neglecta: Western Meadowlark. 



Almost all the records for Meadowlarks are for neglecta, 

 but Percival reports both this and neglecta. He has skins 

 of bijth. (See his local list.) 



501. Sturnella neglecta: Western Meadowlark. 



Very abundant summer resident throughout Wyoming at 

 the lower and middle altitudes. 



507. Icterus galbula: Baltimore Oriole. 



Percival reports that it is a fairly common summer resident 

 in the region of Hat Creek. The third edition of the A. O. 

 U. list reports it from Wyoming, but we know nothing of 

 their authority for the statement. 



508. Icterus bullocki: Bullock's Oriole. 



Fairly common over most of the state ; occurs in less num- 

 bers in the northern portion than in the central portion and 

 southward.
