Natural song of an apparent Yellow-breasted Chat × Icterus sp. hybrid recorded by Curtis A. Marantz on 27 April 2020 along San Timoteo Creek at the San Timoteo Nature Sanctuary, Redlands, San Bernardino County, California. This bird was initially found by Matt Grube on 10 September 2019 and relocated by him on 25 April 2020 after returning following an absence over the winter (though apparently photographed the previous day and misidentified as a chat). When recorded at 7:02 am, the bird was in the same, isolated Blue Elderberry tree on the north side of the trail that parallels a riparian corridor dominated by willows and with a scrubby field to the north approximately 1.4 kilometers by trail northwest of the entrance gate along Alessandro Road. The bird was about 12 meters away and six to ten meters up in the same tree where it was in the previous recording. Bird was seen well and photographed both before and after this recording was made. Recording was made using the low-cut filters on both the MKH-20 and the recorder, but without the attenuators on either the microphone or recorder. Weather was clear, almost calm, yet with a trace (5 knot) breeze from the northeast, and probably in the mid-50s, given that it was 53º on my arrival at the site.
