    The quarterly update of the Barred Owl Observations Database is available in the BIOS Viewer for CNDDB subscribers. The barred owl database includes barred owl (Strix varia), Strix hybrid, and unknown Strix detections.

    Many of the records represent incidental detections made during spotted owl surveys; therefore, this dataset may not accurately represent the current distribution of barred owls in California. Furthermore, this dataset is only available to CNDDB subscribers because it contains references to sensitive spotted owl locations. A public version will be available in the future.

    For a copy of the geodatabase or for site-specific inquiries, contact the database manager at owlobs@wildlife.ca.gov.

    Fall is officially here! The California heat is dying down and the fall transition is starting, which means many native species are preparing for the winter months to come. This transition period can create photo and observation opportunities that aren’t available year-round. Here are our favorite photos from September!

    Euphilotes enoptes smithi – Smith’s blue butterfly

    Submitted by Patrick Scott – California Department of Transportation

    This male Smith’s blue butterfly was spotted posing on some seaside buckwheat on the coast of Monterey County. Smith’s blue butterflies start to emerge in the late summer and early fall to mate specifically on two buckwheat species, seaside buckwheat and seacliff buckwheat. They carry out their entire lives within a couple hundred yards of these buckwheat species! This butterfly has been listed as endangered under the Endangered Species Act since 1976. A large reason for their decline is habitat loss due to development, invasive plants, and livestock grazing. We always enjoy seeing endangered species such as the Smith’s blue butterfly fighting against all odds and reproducing in their native habitats. Thank you, Patrick, for this beautiful photo!

    Arctomecon merriamii – white bear poppy

    Submited by Kristin Forgrave

    This delightful perennial was found along the Tetracoccus Ridge in Death Valley National Park. It is listed as a 2B.2 (rare or endangered in California, common elsewhere) in the California Rare Plant Ranking system. Arctomecon merriamii can also be found in Nevada where it is considered vulnerable. In California, it is commonly found in rocky areas of chenopod scrub, or Mojavean desert scrub. Having missed the April to May flowering period, it is no surprise we see the fruiting bodies on this individual. Thank you, Kristin, for the hard work you do and the amazing photos you provide!
