was observed making its way np the Middle Loup valley. 

 It was probably a belated migrant, since the species does 

 not breed in this locality. 



6i. Archilochus colubris (Linnaeus) — Ruby-throated Hum- 

 mingbird. 



I secured a young male Ruby-throated Hummingbird on 

 September 3, 1912, from the undergrowth along the Middle 

 Loup river. This record extends the limit of distribution 

 of this hummingbird in Nebraska for some distance west- 

 ward. Previously the 98th meridian, lying about one hun- 

 dred and fifteen miles east of Halsey, marked the supposed 

 western boundary for this species. The Broad-tailed 

 Hummer [Selasphorus platyccrcus (Swainson)] common 

 west of here, has been found at Bassett, about thirty-seven 

 miles east of the Reserve, so it might occur here also, al- 

 though no records of its doing so are at hand. 



62. Tyrannus tyrannus (Linnaeus) — Kingbird. 



Kingbirds were quite common at Halsey up to the time 

 of my departure on September 10, 1912, but had been ab- 

 sent on September 20 of the preceding year when I stopped 

 at this locality again on my return from more western parts 

 of the state. The intermediate period of September 10-20 

 probably includes the date of departure of the species. 

 One nest with a set of four eggs was discovered on June 

 10 about eight feet from the ground in a willow overhang- 

 ing the Middle Loup river, and numerous pairs of the birds 

 were found along that stream, all of which were undoubt- 

 edly breeding. A single Kingbird was seen back in the 

 hills on May 19, 1912, in the grove of large hackberries 

 south of the heronry, but this was during migration and I 

 do not suppose that the Kingbird will nest in that situa- 

 tion. 



63. Tyrannus verticalis Say — Arkansas Kingbird. 



The Arkansas Kingbird was not an abundant bird but 

 was seen on several occasions throughout the summer of 

 1911 and 1912 and may have bred sparingly. It was noted 

 in the undergrowth along both the Middle Loup and Dis- 

 mal rivers, in the open valley, and in pockets back in the 

 hills. One was seen several times about the little clump 

 of hackberries that contained the nest of the Swainson 

 Hawk, and I suspected the presence of its nest at that
