Lapland Longspur at Avra Valley
This Lapland Longspur was found by Andrew Core at the Avra Valley Waste Water Treatment plant southwest of Tucson Arizona three days ago, and has been seen by several people since then. Mich Coker and I saw it this morning, November 27, along with Bob Beatson, Randy Grohman, and Peggy Wang. Not so visible in these photos (digiscoped with an iPhone through an 85 mm Zeiss Diascope zoomed all the way in to 60X) are the strongly rufous-edged greater wing coverts and tertials. The ear coverts have more of an outline and the bill is smaller than on McCown's Longspur as well. It was hard to pick out of the many Horned Larks it was associating with – look for the smaller, darker appearance with the binoculars, while the streakiness is visible only through a spotting scope at the distance we were at.
