NOTES: Neotropical Institute Cut # 22. Bulk reel: 239
a) 11:30 AM to 12:00 PM. Weather: Clear, fair, windy. Male had been singing periodically all AM. AT ~ 11:30 I heard a (male-female) duet and came to area with equipment. Before turning on recorder I whistled the female song and male responded immediately with the usual multi-figure phrase. The last such trial was recorded, being the first on the present cut, but after this the male did not respond to my female imitation for some trials, only a few of which are here saved; instead he went on singing the two-figure phrase.
However, after a while he again responded, frequently but not always, to my female imitation. And then the female herself began to sing the prolonged phrase and male responded invariably to that and eventually flew over to her. Part of this recording was made with approximate focus on the female.
The male's failure to respond always to my female imitation is almost surely due to some deficiency in my imitation, for he responded without fail to the real female. Quality: 1 & 2. Level: 0. 139 tape. Std. Copied SN to N-IV in field.
b) 3:55 PM. Clear, windy. Male two-figure song, natural. (The bird has been singing periodically all day and one one occasion I heard the female with it, too.)
I subsequently tried whistled imitation of all kinds (female two-figure long and short and male two-figure and multi-figure) but the bird paid no attention, continued to sing the same two-figure phrase. Quality: 1. Level: 0. 175 tape. 3 3/4 ips. Std. Copied SN to N-IV in the field.
c) 17/VI/73. 9:20 PM. Clear. Male two-figure song at night; bird had already been singing for > 30 minutes without interruption before this was recorded. Quality: 1. Level: 0. 175 tape. 3 3/4 ips. Std. Copied SN to N-IV in the field.
