Media notes
Calls by two Pinyon Jays recorded at 7:54 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 (34.27706º N, 116.74918º W). I had been watching the bird on-axis for some time before a second bird took flight and then the bird in front of me did so as well. The calls were probably all given in flight when the birds flew off, with the initial call and two additional calls given by the more distant bird but only one call given by the bird on which I concentrated. The bird I was watching, and of which I took several photos, was perched quietly about 15-18 meters up and 20 meters away in the top of a pinyon pine amid open Pinyon Pine-woodland in the floor of Lone Valley. I had done some “spishing” and “squeaking” prior to making this recording, but the bird did not appear to react to this. It was clear with an intermittent, mild (5 knots) from the southeast, and temperatures that were probably in the low 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
(calling; although I never saw more than two birds at one time, we repeatedly heard what sounded like small groups of Pinyon Jays scattered about the valley, for an estimated total of six or eight birds)
