TYRANT FLYCATCHERS. 



444. Tyrannus tyrannus (Linn.). 

 Kingbird. 

 Summer resident and common up to 8,000 feet in east- 

 ern Wyoming. In the western half of the state this species 

 ■is rather scarce; but I have seen quite a number of these birds 

 on the western side of the Big Horn basin and Drexel took a 

 specimen at Fort Bridger in 1858. Cooper reports taking a 

 specimen at Fort Laramie, in 1857 ; Coues makes a few refer- 

 ences to Wyoming records; Bond finds them common at 

 Cheyenne; Jesurun reports them common at Douglas; Cary, 

 "fairly common along Beaver creek, seven miles from New- 

 castle." I have also noted this species from the following 

 places : Sundance, Buffalo, Casper, Chugwater, and Alcova. 

 :There are two skiiis in the University collection. 



447. Tyrannus verticalis Say. 

 Arkansas Kingbird. 



Summer resident and common up to 6,000 and occasion- 

 ally breeding up to 7,000 feet. This bird prefers the plains 

 and breeds along wooded streams in great numbers. Wood 

 took four specimens on Pole creek July 28 and 29, 1856 ; Drex- 

 el reports specimens taken at Fort Bridger in 1858; McCar- 

 thy took specimens at Fort Laramie, Aug. 27, 1857; Grinnell 

 reports this species from Yellowstone park, 1875, and also the 

 following note from Lake Como, 1879 : "Seen several times 

 on Rock creek, where no doubt it bred, as it certainly did on 

 Foot creek, 25 miles further southwest. On the latter stream 

 •young birds just from the nest were taken. Bond finds them 

 common at Cheyenne ; Jesurun reports thein plentiful at Doug- 

 las. I have observed or taken this bird from the following 'lo- 

 calities : Sundance, Newcastle, Casper, Fort Steele, Evanston, 

 Alcova, and Bates' Hole.
