May, 1918 THE SHORT-EARED OWL IN SASKATCHEWAN 103 



Two days later, May 22, I was drilling flax in another part of the same 

 field, where it had not yet been disced. 1 was standing on the seed box and 

 keeping a weather eye open for ducks or other birds to flush, when an owl flew 

 up from beside the horses. A short search revealed the nest, containing seven 

 iresh, pearl-like eggs. This nest varied little from the first one found, the main 

 difference being a less amount of lining. 



May 31 found me discing in another field of wheat stubble about a mile 

 from that in which the first two nests were found. While driving back and 

 forth across the field, which, by the way, was a mile long and a mile wide, I no- 

 ticed a number of white objects scattered within a radius of three feet on 

 ground already disced. Upon examination they proved to be owl eggs and only 

 one of the six eggs found was damaged in the least. The nest, located by some 

 white feathers, did not differ markedly from the others. The eggs were incu- 

 bated one-half. 



On Sunday, June 3, another workman on the farm told me of a nest he had 

 noticed the day before. I immediately saddled a pony and rode out to have a 

 look. On that part of the field to which I was directed we had burned off the 

 stubble a week previous. All through the burnt part were small patches of 

 stubble which had been too damp to burn, and it was in one of these that I saw 

 the owl brooding on her nest and glaring at me with wide-open eyes. I rode 

 within ten feet of the nest before she flew off and disclosed a set of seven eggs. 

 Incubation was well along. 



It was on June 1 that I found a third owl nest, or more precisely, the re- 

 mains of a nest, in this same field. I was dragging the disced ground with a 

 six-horse, spike-toothed harrow when I noticed some eggs disappearing under 

 the machine. I managed to find two whole eggs and several shells scattered 

 about, and one week-old owl nearly covered with soil. A nest was manufactured 

 in short order and the owl installed. On Lhe next trip down the field the old 

 bird was seen brooding on her new nest as if nothing had happened.

NOTES OX THE NESTING HABITS OF THE WHITE-THROATED SWIFT 



IN COLORADO 



By WM. C. BRADBURY 



WITH SIX PHOTOS 



AFTER the excellent article by Mr. Hanna on the White-throated Swift 

 in the January, 1917, number of The Coxdor, it might seem superfluous 

 to chronicle my own observations, but the Editor has suggested these 

 might prove interesting, if only for comparison or corroboration. 



Early in June, 1916, Mr. J. D. Figgins, Director of the Colorado Museum of 

 Natural History, returning from a mountain trip reported a number of White- 

 throated Swifts (Aeronautes melanoleucus) about a promising nesting site 

 near Hot Sulphur Springs, Grand County, in this state. After fully discussing 

 the matter, I provided a quite complete collecting equipment for cliff work, in- 

 cluding block and tackle, sailor swing outfit and accessories good for two hun-
