  1. White-lined Sphinx Moth (Hyles lineata)

    White-lined Sphinx Moth (Hyles lineata)

    This moth is identified by the long pale stripe on its forewing combined with its stout furry body and pink band on its hind-wing. Also notice the six white bands on its abdomen. They are sometimes called "Hummingbird Moths" because of their hummingbird-like behavior and size. Members of the...
  2. Common Loon

    Common Loon

    This is an adult in breeding (definitive alternate) plumage showing the dizzying black-and-white checkerboard pattern to its back. This iconic species is primarily a migrant and winter visitor to California from breeding grounds in boreal lakes of Alaska and Canada. They feed by diving, often...
  3. Hooded Merganser

    Hooded Merganser

    Following up on a tip, I checked out this urban park hoping to get better pictures of Hooded Mergansers. I was not disappointed. This adult male has its crest fully raised giving it a rather outrageous foppish profile. Fully raised crest is often part of a highly ritualized courtship display.
  4. Eared Grebe

    Eared Grebe

    This species is common in the western United States, but rare in the East. Most of the grebes are still in winter (basic) plumage, but this Eared Grebe has almost completed its molt into breeding (alternate) plumage showing golden fan-shaped head plumes. The peaked crown, mostly black neck and...

    If looks could kill...

    This male Hooded Oriole does not look happy about the camera. Many of these orioles are staying near the nectar and jelly feeders. I may see six or eight males and a few females at a time. And they sure can fuss with one another. https://www.allaboutbirds.org/guide/Hooded_Oriole/overview
  6. Harlequin Duck

    Harlequin Duck

    I've been hoping to get closer photos of this long-staying Harlequin Duck and this afternoon I finally succeeded. Notice the loose feathery tips to the white scapulars. Formerly more common, this species is now a rare visitor to California but this individual has been resident here since 27...
  7. A lovely couple

    A lovely couple

    Yellow-rumped Warbler — https://www.allaboutbirds.org/guide/Yellow-rumped_Warbler/overview There are several sub-groups of the Yellow-rumped Warbler and I’m uncertain which I’m seeing between one bird and another. This male is of the more brilliant colors while others are more gray with subdued...
  8. Allen's Hummingbird

    Allen's Hummingbird

    This is an adult male of the nominate race, S. s. sasin which breeds along the immediate coast of California and winters in Mexico. The narrow, pointed tail-feathers help distinguish it from the more widespread Rufous Hummingbird (S. rufus). The two hybridize in a coastal area of northwestern...

    Sitting in the evening sun on the edge of the bath. I usually see this bird near low bushes foraging for seeds. This is a very west coast bird.

    This short video clip shows the main courtship ritual culminating in a spectacular "race" across the water.
  12. Western Grebes

    Western Grebes

    This photo is a screen grab of a video I took this afternoon. Famous for their elaborate courtship rituals, this photo shows the "race" where two grebes run across the surface of the water upright on their feet, their necks bent forward and head angled up. I have seen plenty of video footage of...

Sometimes called Southern Pacific Pond Turtle (A. m. pallida). Often placed in the genus "Clemmys," these are California's only native...
  14. Bewick's Wren

    Bewick's Wren

    More often heard than seen, these active little wrens with bold white eyebrows move furtively in dense brush. This individual shows gray flanks and a very long thin bill representative of the race "T. b. spilurus" which ranges along the central California coast from San Francisco to Monterey...
  15. Black-headed Grosbeak

    Black-headed Grosbeak

    This is March 26 and today this handsome boy returned from his winter migration to Mexico. There is a pretty lady with him and I’ll post a picture of her soon.

    Acorn Woodpecker

    Emerging from a cavity in a telephone pole, this is an adult male showing more extensive red on the crown and a pale eye. These clownish-looking woodpeckers are famous for their communal breeding strategy in which multiple females and multiple co-breeding males care for the young. The females...
  19. Black-legged Kittiwake

    Black-legged Kittiwake

    This is a rare visitor to our coast but exceptional numbers have been seen on local seawatches in recent weeks. They breed in the Arctic but usually disperse out to sea in the winter. This is an adult in winter plumage showing the "dipped in ink" wing-tips and black feet. Note the dark...
  20. Rufous Hummingbird

    Rufous Hummingbird

    I try to post pictures in a more natural setting but this closeup has nice color and feather detail, so I go ahead and do it. A handful of Rufous and Anna’s hummingbirds stayed through the mild winter.

    Western Sandpiper

    Clustered tightly together at a high tide roost, these Western Sandpipers are starting to show first signs of breeding plumage. These small unassuming shorebirds are still mostly in winter (basic) garb, rather nondescript gray above and white below. But if you look carefully you may see a few...

    Thanks to Pat Boor for locating this bird on 28 January. This adult female was first noted here four years ago 25 January 2018 and it has returned every winter since. She can be difficult to pick out when her head is tucked and sleeping. Notice the faint purple gloss to her head which is...
