24 (Zonotrichia leucophrys). Other avian species observed include American crow and turkey vulture (Cathartes aura). A feral cat was also observed roaming though the Property. It is likely that common raptor species such as red-tailed hawk (Buteo jamaicenesis), Coopers hawk (Accipiter cooperii), and American kestrel (Falco sparverius) could utilize the annual grassland habitat for foraging. Extensive burrow colonies created by small mammals including, but not limited to, Botta’s pocket gopher (Thomomys bottae), California ground squirrel (Otospermophilus beecheyi), and various vole species (Microtus spp.) were also observed. Common reptile species such as western fence lizards (Sceloporus occidentalis), Pacific gopher snake (Pituophis catenifer catenifer) and California king snake (Lampropeltis californiae) may also occur. While not observed during the various surveys, there are numerous special-status species that may utilize this habitat. This includes the Crotch and Western bumble bees, both of which may forage or nest within the Property. Both species are known to occur in urban areas with modified landscapes. However, neither species has been observed in the area since 1952 or earlier. Other special-status species that may occur include burrowing owl (Athene cunicularia) which may utilize mammal burrows that occur in the friable soils of the Property. Signs of burrowing owls were not observed during the surveys, but species-specific surveys were not conducted. The northern harrier (Circus cyaneus) may forage or nest within the annual grassland habitat, but the abundance of walnut trees and snags within the area would likely inhibit the species. However, the Property provides suitable foraging habitat for the white-tailed kite (Elanus leucurus). There is also the potential for pallid bat (Antrozous pallidus) to forage and roost throughout the habitat area. Oak Woodland Although limited in extent, the oak woodland habitat within the Property may provide suitable nesting habitat for a number of passerine and raptor avian species, as well as provide suitable roosting habitat for bats including potentially sensitive species such as the pallid bat (Antrozous pallidus). 6.4.2 Special-status Wildlife A protocol level survey was conducted for CRLF in 2022, and it was determined that no CRLF occur within the Property. However, specific surveys were not conducted for other special-status species with a potential to occur within the Property; these species are discussed below.
