W[illegible] Davis 1935. 474 Berkeley, Alameda Co., Calif. Dec. 9, Ward Russell brought into the museum today two adult Horned Owls that were collected. On these I found several large parasitic flies which I collected and took over to the Entomology department and gave to Professor Verms, [illegible] tentatively identified them as Family Hippoboscidae, Genus Offertia, species americana. They were well gorged; wings longer than abdomen; had parasitic ticks or mites attached to the abdomen; flattish in build and very peculiar in action. They moved sideways quite as readily as they did forward. These are to be experimented with to see if they can transmit malaria to quail. Dec. 20. I picked up a Ruby-Crowned Kinglet yesterday morning at the corner of Fulton and [illegible]. It was dead, but in good condition as regards plumage. See field no 1584. The stomach was about half full of insect and vegetable remains. No cause of death was found, i.e. no apparent injuries.
