38. Snowy Owl. Nyctea nyctea. The winter of 1917-1918 
witnessed a very remarkable flight of Snowy Owls in this area, 
which was reported in detail in a previous volume of these Pro- 
ceedings.^ During the winter of 1918-1919 there was still evi- 
dence of a southward movement of these birds. But during the 
winter of 1919-1920 none were reported or brought in. These 
facts seem to cast a shadow of doubt upon the weather conditions 
being the primary cause of the movement. If the owl invasion 
of 1917-1918 was due to the failure of their food supply in the 
north (rabbits and hares) the partial movement of 1918-1919 
would suggest a slow and proportionate recovery of the normal 
rabbit population in the north. The following records are to be 
reported for the season of 1918-1919 in the area being consid- 
ered : 
November 7, 1918, a male from Parkston, South Dakota. No. 3290. 
November 21, 1918, a female from Westfield, Iowa. No. 3295. 
November 26, 1918, a male from Cole’s Addition, Sioux City. No. 3298. 
December 4, 1918, a female from Renville, Minnesota. No. 3307. 
December 5, 1918, a female from Bridgewater, South Dakota. No. 33(B. 
December 5, 1918, a female from Alta, Iowa. No. 3309. 
December 8, 1918, one at McCook Lake, South Dakota, Field Record. 
December 27, 1918, a female from Artas, South Dakota. No. 3317. 
January 20, 1919, one from Anthon, Iowa. 
February 3, 1919, a male from Hudson, South Dakota. No. 3340. 
February 3, 1919, a male from Hudson, South Dakota. No. 3341. 
February 3, 1919, a female from Hudson, South Dakota. No. 3342. 
Specimen No. 3298 was shot while in the act of killing a quail. 
The record of December 8, 1918, was made by A. F. Allen. 
The specimen from Anthon, Iowa, was sent in alive to the Stone 
Park collection. 
39. Kingfisher. Ceryle alcyon. The kingfisher has never been 
recorded here as a winter bird, so far as the writer is aware. 
The following note of Mr. Weir R. Mills will, therefore, be of 
interest: ‘T saw a Belted Kingfisher on January 1, 1920, near 
Pierson (Iowa). Although the day was cold and there was con- 
siderable snow on the ground, there were a few spots where the 
stream was not frozen over, and this was where I saw the bird. 
I had a fine opportunity for observation, and I am absolutely 
sure of the identification — never was more sure of anything.’" 
40. Pileated Woodpecker. Phloeotomus pileatus. Mr. An- 
derson received a specimen of this bird on November 22, 1918, 
from Hill City, Minnesota. It would probably be abieticola.
