Observations on Raptorial Birds in the Lava Beds: Tule Lake Region of Northern California
Bond RM. 1939. Observations on Raptorial Birds in the Lava Beds: Tule Lake Region of Northern California. The Condor. 41(2):54-61
This paper records observations made by the author during a total of 36 days in 1937 and 1938. Months of observation are spread out throughout the year. A comparison chart shows numbers of specimens cited in a 1936 study and numbers cited during 1937. There were significantly less birds cited in 1937, which is believed to be due to a reduction in the number of mice present to feed on. Included in this paper is "Food Habits of Hawks," and "Food Habits of Owls," with a species list.
