Waterford Cove Apartments heron rookery, Sacramento, California, US
May 9, 2019 5:51 AM - 9:10 AM
Comments: Clear skies, breezy, 54 degrees, warming to 59 degrees and calmer. No luck seeing yesterday's reported Yellow-crowned Night-Heron despite prolonged effort. The Black-crowned Night-Herons were very active for the first 20 minutes I was there and slowed down markedly by 9AM, with a few individuals still flying in with nesting material after then. Conversely, the Snowy Egrets became more active. The night-herons were mostly buried in the redwoods and not visible by the time I left.
Canada Goose (Branta canadensis) 17
Mallard (Anas platyrhynchos) 6 All were males, presumably with the females away on nests.
Rock Pigeon (Feral Pigeon) (Columba livia (Feral Pigeon)) 11
Mourning Dove (Zenaida macroura) 1
White-throated Swift (Aeronautes saxatalis) 2
Anna's Hummingbird (Calypte anna) 1
Double-crested Cormorant (Phalacrocorax auritus) 3
Great Egret (Ardea alba) 6 These came in early, landed on the redwoods, and later disappeared. They did not seem to be participating in the nest colony.
Snowy Egret (Egretta thula) 45 A minimum number. Most if not all had breeding plumes and pink lores.
Green Heron (Butorides virescens) 3 All three were flying over the adjacent canal.
Black-crowned Night-Heron (Nycticorax nycticorax) 120 One-hundred twenty is the estimate. Probably more than this, as they outnumbered the Snowy Egrets about 3 to 1 early on. Most were adults, some on nests, many more carrying nesting material. Several were subadults showing no sign of nesting participation. Two were just-fledged juveniles warily inching out on a limb toward their parent.
Turkey Vulture (Cathartes aura) 3
Nuttall's Woodpecker (Dryobates nuttallii) 2
Black Phoebe (Sayornis nigricans) 2
California Scrub-Jay (Aphelocoma californica) 2
American Crow (Corvus brachyrhynchos) 7 Harassing herons and vultures and looking for food.
Northern Rough-winged Swallow (Stelgidopteryx serripennis) 2
Barn Swallow (Hirundo rustica) 6
Cliff Swallow (Petrochelidon pyrrhonota) 13
Bushtit (Psaltriparus minimus) 3
