I spent the day in the Moapa Valley where, shortly after 1pm, I observed an
adult ZONE-TAILED HAWK flying north over Overton WMA. I first saw it near
the grove of large cottonwoods near the residence at the north end. It
circled quickly north and then northeast where it joined a turkey vulture
before I lost it. I raced north into town and to the spot where the river
crosses Cooper Road. I staked this out for about 40 minutes watching as
vultures worked north in small groups and singletons. I never did catch
back up with the zone-tailed.
Other birds of note at the WMA included a Snowy Egret, a couple of Bell's
Vireos (my NV FOS), a Violet-green Swallow, and a Lucy's Warbler. The only
shorebird present was an American Avocet. Further north along the river
near Moapa, Lucy's Warblers had arrived in numbers, as they did throughout
southern NV this week.
Highlights at Bowman Reservoir included a Common Loon and an Osprey.
Nothing of note was at sites along the Overton arm of Lake Mead.
