these in Mr. Brewster’s museum he identifies as typical gyrfalco. Gyr- 
faleons arrive in November, usually about the 8th. The latest date I 
have seen one was March 7. They prey entirely on ducks and the smaller 
geese. It was seldom that there was more than one on the prairie at a 
time, and the smaller falcons worried them continually. I once saw a 
Prairie Faleon badger a Gyrfalcon for about two hours following it from 
tree to tree and striking at it continually. 
104. Falco mexicanus. Prarrir Fatcon.— At one time a regular 
fall and winter visitant, though always scarce. Of late years very rare. 
Last one taken July 27, 1896, a young bird. 
105. Falco peregrinus anatum. PEREGRINE FALcon.— Scarce 
migrant. I have seen, but not taken, two or three very dark birds that may 
have been pealei. Young birds of those taken though dark had the light 
edging to the feathers of the upper surface typical of anatum. 
106. Falco columbarius columbarius. Pigeon Hawx.— 
107. Falco columbarius suckleyi. Biack Mrriuin.— 
108. Falco columbarius richardsoni. RuicHarpson’s MErR.iIn.— 
Of the three Merlins suckleyi was the commonest, then colwmbarius, with 
richardsoni rare, only two of the latter taken and one of these not quite 
typical. Out of about thirty birds taken I saw no intergrades between 
columbarius and suckleyi. Since then I have taken two intergrades east 
of the Cascades. The Black Merlin is the only subspecies seen in the 
summer before August, but I never found it breeding. 
109. Falco sparverius phalena. Desert Sparrow Hawxk.— Per- 
manent resident. Common. 
110. Pandion haliaétus carolinensis. Osprey.— Common, leaving 
for the south early in the fall just when the streams are commencing to 
swarm with salmon. 
111. Asio wilsonianus. LonG-EARED Owx.— Permanent resident. 
Scarce. 
112. Asio flammeus. SHortT-EARED Owi.— Common resident, oc- 
casionally a few pairs remain to breed. A full grown young bird taken in 
July was very dark and rufous. 
113. Strix occidentalis caurina. NortTHerN Spotrep OwL.— Very 
rare. I purchased a very poor mounted specimen from Mr. Wm. Hall 
who got it at Mount Lehman, some fifteen miles down the Fraser River 
from Sumas, where a pair had reared a brood of young. During the eleven 
years I resided at Chilliwack and Sumas I worked very hard for this bird, 
visiting all likely localities and offering rewards for any owls brought me 
with dark brown eyes, but could get no trace of it. Returning for a brief 
visit in the winter of 1909, I was delighted to secure a fine specimen close 
to my old home. I had gone out on January 28 to try a little 22 pocket 
pistol on the jays and squirrels which were a pest, and after shooting a 
number of these I got first a Goshawk, and a little later this beautiful owl. 
114. Scotiaptex nebulosa nebulosa. Great Gray Ow1.— Very 
rare. The last record I have was of onekilled in January, 1890, at Sumas. 
Prior to that it was of fairly regular occurrence in the winter.
