Weather: Fair. This is a captive adult male. Calls, no song. Quality: 2. Level: +3. 203 tape. LN.
In one place (perhaps in others that I haven't detected) this bird evidently replies to a call by a wild bird; this wild bird's call is similar to that given by my subsequently captive females during nocturnal migratory restlessness.
The captive male of Cut 1) was taken to the field by Helio Martinez (its owner) and me to try to catch wild birds of this form. No adult males were seen but two birds of the year were taken, both subsequently proving to be females.
