COUNTING BY HUNDREDS

I was co-leader on a birding trip at the Chico Goose Fest today…we hit Llano Seco, then Delevan and finally the main unit of the Sacramento National Wildlife Refuge.  Here in winter you count waterfowl by the hundreds: Tundra Swan,  Snow and Ross’s Geese in rows that resemble snow drifts, White-fronted Geese, pintails, shoveler, wigeon, coots…and their fellow marsh birds, White-faced Ibis.  Equally abundant are Brewer’s and Red-winged Blackbirds.  We even invadad one pondside roosting site at Delevan and spooked over a hundred Black-crowned Night-Herons.

We found Great Horned Owl and a pair of Red-tailed Hawks already on nests–both are early nesting species along with Bald Eagle.  This morning I also saw Gadwalls copulating.  They are one of the ducks likely to breed here in the Sacramento River Valley.  Most of the hundreds of thousands of ducks are here only for fall and winter.

Did I mention the nonchalant Pintails at Llano Seco who act more like barnyard chickens?PINT SOUJNDPINTAIL CTRPart of the Delevan night-heron roostery:bcnh crowdGE BY ROADGEESE OVRHEDAlmost any glance skyward today caught movement of geese, ducks, swans, cranes, ibis, gulls, raptors…the air ways were crowded at times…sky viewLet sleeping wigeons float…WIG MAILDelevan Rock Wren on his dominant perch, a piece of earth-moving equipment:R-WREN2
