190 Sitst Annual Report 
Falco sparverius deserticola Mearns. Desert Sparrow Hawk. 
Abundant through the hills and canyons. Usually seen hunting 
in pairs. A pair of this species appeared to have a nest in a crevice 
on a rocky cliff, judging from the sound which frequently came from 
that point. Infested by Nirmus fuscus. 
Strix pratincola Bonap. Barn Owl. 
In the eucalyptus grove mentioned above as a buzzard roost, one 
3arn Owl was taken. 
Geococcyx californianus (Less.) Baird. Road Runner. 
Quite common, all through the hills. One was seen on the beach, 
feeding at the water’s edge. When frightened, they usually do not 
fly, but make for the nearest cactus patch or chapparal, at top speed, 
and their speed on foot is altogether remarkable. In a stomach 
examined were the remains of several cicadas, grasshoppers, and 
smaller insects. Infested by Nirmus splendidus. 
Dryobates nuttallii (Gamb.) Ridgw. Nuttall Woodpecker. 
Owing to the general absence of trees, very few woodpeckers 
were seen. One was taken in Aliso Canyon and proved to be this 
species. 
Colaptes cafer collaris (Vigors). Red-shafted Flicker. 
Uncommon here, and shy, only one or two being seen, and several 
heard. 
Calypte anna (Less.) Gould. Anna Hummingbird. 
Very common wherever flowering plants oceurred. Undoubtedly 
C. costae oceurs with this species. 
Tyrannus verticalis Say. Arkansas Kingbird. 
Common everywhere. They were especially frequent about euca- 
lyptus groves. In the town they kept up a continual noise, and seemed 
to be very quarrelsome. Two of them easily drove away a sparrow 
hawk that seemed to be trespassing on their domain. Infested by 
Nirmus foedus. 
Tyrannus vociferans Swains. Cassin Kingbird. 
More retiring than 7. verticalis. Far up Aliso Canyon one speci- 
men was taken. Far inland, others also were seen. I did not notice 
them in company with 7, verticalis. 
Myriarchus cinerascens (Lawr.) Sel. and Saly. Ash-throated Flycatcher. 
Often in the company of the noisy kingbirds. Many times single 
specimens were noted sitting quietly on some stump or wire waiting 
for ameal. They occasionally give a plaintive call that is very char- 
acteristic.
