It was decided that a couple more cuckoo surveys were in order to discover if any were attempting second broods, so Jennie and I were back in Pesqueira Canyon near Nogales. We did detect one YELLOW-BILLED CUCKOO calling, but didn’t get to see it and weren’t able to witness any potential breeding behavior.
We did find an impressive 48 species in this unremarkable canyon, with migration in full swing. Highlights included GRAY HAWK, at least 20 GRAY FLYCATCHERS, DUSKY-CAPPED and ASH-THROATED FLYCATCHERS, a migrant THICK-BILLED KINGBIRD, BLACK-TAILED GNATCATCHER, at least seven CRISSAL THRASHERS, a latish LUCY’S WARBLER, BOTTERI’S and LINCOLN’S SPARROWS, six GREEN-TAILED TOWHEES, SUMMER and WESTERN TANAGERS, BLACK-HEADED and BLUE GROSBEAKS, a couple of VARIED BUNTINGS, and an impressive 16 migrant BULLOCK’S ORIOLES.
On the way out of the canyon, we stopped at Pesqueira Canyon Pond, which has really filled up. We found eight CINNAMON TEAL, three BLACK-NECKED STILTS, and three SPOTTED SANDPIPERS, as well as a few nice dragonflies.
