: <K, NE8T8 AND BOGS OF 



Ohio, exhibit the following sizes: .79x.50, .80x.50, .80x.52, .77x.50, .79x.53. The eggs 

 in a large series range from .74 to .86 in length and from .47 to .55 in breadth. 



424. VAUXS SWIFT, rh.itum nni.rii (Towns.) Geog. Dist. Pacific coast 

 of the United States northward to British Columbia; south in winter to Lower Cali- 



This is a lighter colored and smaller species than the Chimney Swift. The 

 habits of thr t\vo birds, however, are similar, except that Vaux's Swift is said only 

 to nest in hollou D various regions of Oregon and in Washington this species 



is a common summer resident, where it breeds in May and June, fastening to the in- 

 side walls of hoi: "inks and stubs the half-saucer-shaped nest of twigs, which 

 is glued together with the bird's saliva. Three to five/ narrow-elliptical white eggs 

 are deposited, which have an average size of about .72x.50. Very few of this bird's 

 eggs have found their way into collections. 



425. WHITE-THROATED SWIFT, tfriinniitnt melnnolntcus (Baird.) Geog. 

 Dist. Western United States, from the Black Hills, Northern Wyoming and 

 Southern Montana to the Pacific; south in winter to Guatemala. 



The late Major Bendire states that the range of the "Rock" Swift, as it is com- 

 monly called, does not appear to extend nearly as far north in the mountains of the 

 Pacific coast districts as it does in the Rocky Mountain region, where it is generally 

 distributed throughout suitable localities, from Southern Arizona and New Mexico 

 ward, through Colorado and Wyoming to Montana. The latter, as far as known, 

 marks the northern limits of its range. Here it was found breeding by Mr. R. S. 

 Williams in small numbers in holes in a limestone cliff on Belt River, about the 

 middle of July. 1881. It was found by Mr. Robert Ridgway to be abundant in the 

 same situations in the Ruby Mountains and in the East Humboldt range, but less 

 abundant in the Wasatch Mountains in Utah. The eggs of this species still remain 

 among the special desiderata in oological collections and, according to Bendire 

 (1895). there are none in the U. S. National Museum collection. Mr. Walter E. 

 nt gives us the best description of the eggs I have seen. It is in the September 

 number of the Nidologist for 1894, and is as follows: "More than a dozen years ago 

 an imperfect set of five fresh unblown eggs of the White-throated Swift were pre- 

 sented to me by a young man in Contra Costa county (California). They were taken 

 a nest in a crevice in the back of a tunnel-shaped cave in the side of a cliff 

 about twenty feet above the base. In color the eggs are pure white, narrowly ellip- 

 tical In form, but rather smaller at one end. They measured: .87x.53; .88x.53, 

 .88x.52. .86x.50; the fifth was too much damaged to measure accurately. The eggs 

 were collected on June 6. 1878." 



428. KIVOLI HUMMINGBIRD, /;//</' mx /,//,/< * (Swaim.) Geog. Dist 

 Southern Arizona and tablelands of Mexico to Nicarauga. 



One of the largest and one of the most handsome Hummingbirds found within the 



limits of the United States, and it is generally known as the "Refulgent Humming- 



" Within our limits it is not an altogether common summer resident. It has 



been obtained in the mountains near the Mexican border, in Arizona, and in the 



me southwestern portion of New Mexico. It was first added to our avifauna by 



haw. who took a specimen near Fort Grant, Arizona, in September, 1873. The 



Major Bendire describes two nests that were taken in the Hna< hu< a Mountains, 



Arizona. One of these, the best preserved one, resembles the nest of the Ruby- 



throntfd HnmmineMrfl vorv rlosoly. but like the bird, is considerably larger. It 



wan found by Mr. L. Miller on June 22, 1894, at an elevation of 7000 fret, saddled on 



t walnut branch about ten feet from the ground and contained one young bird nearly
