Hi, all.
-- Just a quick note here to let folks know that Greenlee "Reservoir" and adjacent Waneka "Lake" are seriously infested right now with seriously photogenic Snowy Egrets and Great Blue Herons and a few Black-crowned Night-Herons. You might reasonably infer that they're attracted by hackberry psyllids, but, no, it seems that bullfrogs are the draw. With both bodies of water being drawn down (perhaps for diversion to Mars?), the bullfrogs are easy pickings.
Despite great-seeming conditions, there aren't many shorebirds. But ducks--Green-winged, Blue-winged, and a few Cinnamon teal, and Wood Ducks--are plentiful. Eurasian Collared-Doves galore, and a few African Collared-Doves hanging on. The Bushtits are catch-'em-if-you-can. Will the Barn Swallows ever leave? Well, I think the Swainson's Hawks are finally gone. The Great Horned Owls are marvelously vocal, dawn and dusk.
Oh, and I saw and heard a Rock Wren there the other day! My first at the preserve since my pre-eBird days, so my 232nd species for the site. A migrant, of course, and he went straight for the rock pile on the northeast corner of Waneka Lake. Figures. Exact same place that I saw one in May 2006, pre-eBird.
