Media notes
This represents an unbroken cut with calls by two Gray Vireos recorded at 8:12 am and then song recording at 8:14 am by Curtis A. Marantz on 3 July 2020 along Smarts Ranch Road (Forest Road 3N03) ca. 4¾ miles by road southeast of State Highway 18 in the San Bernardino National Forest, San Bernardino County, California (34.27800º N, 116.74915º W). Two birds, apparently an adult and a juvenile in a family group, were seen foraging and quietly calling about two to eight meters up and 10-25 meters away amid open Pinyon Pine-woodland with a canopy of about ten-meters-tall and an understory of desert shrubs on a small, rocky hill within Lone Valley. The second part of the recording represents song by one of these birds, presumably an adult male. I did see these birds while I was recording and better both prior to and following this period. It was clear with an intermittent from the southeast that was particularly bad during this period, and temperatures that were probably in the low to middle 60s (after a low of 45º F on our arrival at the site). Attenuators turned off but low-cut filters used on both microphone and recorder.
Observation details
(singing and calling; I heard three different birds singing, but the bird we saw was accompanied by at least one additional bird and possibly two, these seen in the same area where we photographed what were presumably the same birds a week earlier)
