Subject: [AZNMbirds] AZ: Cassin's Sparrows

Several people have commented on the appearance of CASSIN'S SPARROWS in more northerly locations in the state. Adding to this information, I detected 57 this morning along a 5.3-mile stretch of Willow Springs Road, compared to only 12 there on 11 July. Many males were skylarking. This road goes through upland desert grassland located between Oracle Junction and Oracle n. of AZ 77 in Pinal Co. This is the highest number I've detected there since 2006 when I first discovered that they likely nested there following the onset of monsoon rains. (Not all summers have they been found there in the past 12 years.) The considerable amount of rain last month likely spurred the appearance of more Cassin's than usual.
