Raptorial Birds in the Cliff Areas of Lava Beds National Monument, California
Dixon JS and Bond RM. 1937. Raptorial Birds in the Cliff Areas of Lava Beds National Monument, California. The Condor. 39(3):97-102
The Petroglyph Cliff area is located northeast of the Lava Beds National Monument (part of this area is under the jurisdiction of the National Park Service). This area has an unusually high concentration of raptorial birds, largely due to the abundance of rodent prey and suitable nesting sites. Ranges of some of the birds extend over about 100 square miles. The author reports that on some occasions, birds were found dead in the area, obviously by the hand of man. It is recommended that some cliff areas that lie outside the monument be annexed to the monument, in order to insure protection of both the petroglyphs in the area and the birds.
