Migration is slowing down and could be finished in Arizona.

There was not much movement, if any, last night throughout Arizona and in southern California. Migration appears to have completed its track this year, but I will continue to check the radar and analyze through the end of May.

Decent migration through the LCRV and much of Arizona, go birding!

I don’t have the loops from this morning, but here are links for the Yuma Radar. Migration looked awesome last night throughout much of Arizona and southern California. Birds appeared to be on the move, everywhere.

Birds moving West, but we’ll see if anything came up the LCRV last night

Regional Overview at ~0400 on 5-19-2012

ARIZONA

Last night, there appeared to be a decent movement of birds near Yuma, but they seemed to be heading in a westerly direction. David Vander Pluym and I are heading out to do some lake watching and to check for migrants at some local hot spots. Central and Southeast Arizona showed little movement last night. I will report back later with any migrants that we find!

Migrants were moving through the LCRV last night!

Greater Roadrunner eating breakfast at the Bill Williams NWR on 5-18-2012

Last night, the radar showed moderate migration throughout the lower Colorado River Valley. Members of the crew observed decent numbers of many species of migrants from Blythe, CA to Needles, CA in the valley. Among the migrants, a few vagrants were also found including a Northern Parula, a rare migrant, near Blythe and a Virginia’s Warbler and Scott’s Oriole, both casual migrants through the valley, in the Bill Williams NWR. Here is a list of migrants observed by the GBBO Crew this morning:

Western Tanager, Willow Flycatcher, Pacific-Slope Flycatcher, Hammond’s Flycatcher, Bullock’s Oriole, Townsend’s Warbler, Hermit Warbler, Swainson’s Thrush, Yellow Warbler, Western Wood-Pewee, Chipping Sparrow, Audubon’s Warbler, Lazuli Bunting, Black-headed Grosbeak, Orange-crowned Warbler, Wilson’s Warbler, and Warbling Vireo.

Note: Greater Roadrunners are not migrants and are residents in the LCRV. It was the only bird picture I took today!

ARIZONA

There was a slight southwest wind last night, possibly pushing a moderate amount of birds up the Arizona side of the lower Colorado River. The birds appeared to be moving in a north northeast direction from Yuma up through the valley. Migrant traps and restoration areas should be checked this morning. There was a light movement of birds across the rest of the state last night.

Lower Colorado River Valley Migration Update–5/17/2012

Western Wood-Pewee at Windsor Beach SP on 5-5-2012

Ah, migration. Spring migration is a truly fascinating phenomena each year and changes from day-to-day. Last night, migration looked awesome in the LCRV with birds moving North out of Yuma up through the valley. Our bird crew went to surveyed multiple locations within forty miles of Lake Havasu City, AZ, which was awesome for ground-truthing my migration analysis from last night. Throughout the area, each crew member observed quite a few migrants including two vagrants, Northern Parula at the Bill Williams NWR and an American Redstart near Ehrenberg, AZ. Good numbers of Wilson’s Warblers and Lazuli Buntings were also observed along with Swainson’s Thrushes, Black-headed Grosbeaks, Western Tanagers, and Orange-crowned Warblers. Other migrants noted recently were Townsend’s Warblers, Pacific-slope Flycatchers, Western Wood-Pewees, and a few Olive-sided Flycatchers.
