Green Heron (Grace Murayama 2-11-17)

As often happens these days, what rain there would be had already fallen, and the morning was cool and pleasant. Yellow-chevroned Parakeets perched in their favorite tree by the archery range fence, and seemed satisfied to stay there. The first surprise was 500+ Canada Geese on the northern cricket field. We searched through them but could find no Cackling Geese. The resident pair of Egyptian Geese attracted a lot of attention from those who had never before seen these golf course-loving waterfowl.

The nesting Great Horned Owls weren’t nesting, or had changed locations, so we wandered over to the ponds. Most of the ducks were American Wigeon, with a scattering of Mallards and Pied-billed Grebes. One Belted Kingfisher flew across the pond, rattle-cackling. All the herons and egrets were present: Great Blue and Green Herons, Great and Snowy Egrets; five Black-crowned Night-Herons hiding in the reeds fringing the pond. Black Phoebes caught insects over the water, then returned to their perches in the brush and reeds. Red-winged Blackbirds also hid among the reeds. The island trees were full of Double-crested Cormorants, Turkey Vultures and one Osprey. White Pelicans, who do not like the ocean or Malibu Lagoon, floated across the pond. One caught a fish.

A bit of an argument arose when a particularly large duck was see among the Mallards. What was it? A goose? It, of course, looked nothing like any bird in the field book. Another exotic like the Egyptian Geese? Had anyone reported it on the L.A. County Bird Hotline?

Mallards (Grace Murayama 2-11-17)

Our white domestic ducks are all mallards, modified by human selective breeding for size and white plumage. They and the regular wild Mallards do not recognize these differences as significant, and they freely interbreed. You can get many variations as the genes for white plumage mix with the genes for typical Mallard plumage. In the bird above, bill and leg color and the partial white neck ring is about all that’s left of the ancestral plumage displayed by the wild male Mallard behind it. Even the little tail curl which all male Mallards have is almost absent.

Brush birds were easily found along the main path: Mourning Doves, Anna’s and Allen’s Hummingbirds, Nuttall’s and Downy Woodpeckers, Scrub-Jays, Bushtits, Bewick’s Wrens, Ruby-crowned Kinglets, Mockingbirds, Orange-crowned and Yellow-rumped Warblers, Spotted and California Towhees, Song and White-crowned Sparrows, House Finches and Lesser Goldfinches. A pair of Red-tailed Hawks rested in nearby trees. Sepulveda Basin can be quite birdy.

We made it to the Los Angeles River which was quite scoured by recent rains. In fact, we saw signs that the water level had recently been at least six feet higher. At the river were more Wigeons and Mallards, plus Coots, Black-necked Stilts in the shade of the Balboa Blvd. bridge and a single Greater Yellowlegs. The day was warming: Red-tailed and Cooper’s Hawks soared as Turkey Vultures floated away on thermals into the misty sky.
