This attractive common species ranges across western North America. The widespread naturalization of introduced Sweet Fennel (Foeniculum vulgare) may account for its being so widespread. This is the typical yellow form. A black form also occurs with reduced yellow striping. Formerly "P. gothica."
A fairly common low growing member of the Evening Primrose family native to coastal California from Humboldt to San Luis Obispo Counties. Sometimes called "Golden Eggs." Formerly placed in the genus "Oenothera" or "Camissonia." Its leaves are edible but reportedly act as a mild laxative.
Restricted to California and Nevada, this one has no English name so I made one up. Sometimes called Stink-beetles or Desert Stink-beetles they are famous for squirting a foul smelling toxic acid from their rear which can burn the skin of potential predators.
In full breeding plumage for only a short time before they migrate back north to breed. A common wintering sparrow in most of California, they usually remain through the end of April. They sing throughout the year, a melancholy "Oh dear me" or "Three blind mice." However hard-luck gold miners in...
An adult in breeding plumage, the striking bright red mouth lining and tongue are not visible unless they are calling. California birds are the race "C. c. eureka" which are smaller with shorter wings, but with a longer bill than populations breeding further north. These distinctive alcids nest...
Note the dark vein outlines on the underside of the wing. Formerly lumped with Green-veined White (P. napi) of Europe and Mustard White (Pieris oleracea) of northeastern North America, it is now recognized as a separate species inhabiting western North America. This is the spring form which has...
Supposedly named for its orange hood, but seems like a misnomer. A proper "hood" should be dark. Historically, these orioles' northern limit was Southern California, but the planting of California Fan Palms (Washingtonia filifera) into Northern California allowed this Palm specialist to expand...
Abundant and widespread across the northern hemisphere, this is a female with a newly hatched brood. Waterfowl chicks are precocial, covered with down feathers, eyes open and feeding themselves immediately after hatching. Most birds have altricial young, hatched blind, naked, totally helpless...
Thanks to a tip from our neighbor Peggy O'Brien, this nice adult male Sora came out in the open briefly. Females are similar but have reduced black on the chest. The name Sora reportedly comes from a Native American name for this shy marsh bird, more often heard than seen. A small chicken-like...
This impressive falcon is perched high on the cliffs overlooking Devil's Slide. The broad facial stripe suggests it is an adult "F. p. anatum," which is the breeding population in temperate North America. It is sometimes called the American Peregrine Falcon and formerly called the "Duck Hawk."...
Looking like a bit of detached bark spiraling up the tree trunk using its stiff tail for support, this cryptic species searches for spiders and other insects using its curved bill like tweezers. Formerly lumped with the similar Eurasian Treecreeper, genetic and vocal studies have shown that it...
Sometimes called "Franciscan Wallflower," this member of the Mustard family is a vulnerable range restricted species endemic to rocky cliffs of the Northern California coast from Sonoma to Santa Cruz counties. It may be confused with the similar Western Wallflower (Erysimum capitatum) but their...
