Butte Valley, California hosts robust numbers of raptors, including at least a dozen species that breed on the valley floor. However, habitat conversion resulting from large scale agriculture has reduced availability of native habitat, including nest sites. The most common tree species used by nesting raptors in this area is western juniper (Juniperus occidentalis), followed by ponderosa pine (Pinus ponderosa), as well as occasional deciduous trees (e.g., Fremont’s cottonwood [Populus fremontii]). Some raptors have also been observed nesting on artificial structures such as platforms on electrical poles and irrigation pivots. We collected microhabitat data at nest trees to determine if Swainson's (Buteo swainsoni) and Red-tailed Hawks (Buteo jamaicensis) showed a preference for certain tree characteristics. These data were collected from occupied nest trees and the nearest neighbors, alongside long-term population monitoring efforts. Microhabitat data included tree height, nest height, number of primary trunks, diameter at breast height, density of canopy, the presence or absence of lichen, lichen type (macro- versus micro lichens), and local tree density. We used logistic regression to test the expectation that Swainson's and Red-tailed Hawks select older and larger trees relative to local availability. The implications of these results could inform which trees are selected for western juniper removal, which is an anticipated treatment conducted by the U.S. Forest Service in Butte Valley.
