Re: ident. of calls on Cut 27, the birds were on the Isla Cigarron, while I was on the mainland and so could not see them. (The recordings were obtained mainly in attempts to record the song of T. tao at dusk.) By comparison with Cut 23 I think there's little doubt the present recordings are of this species, but as the region is new to me and there are Dendrocolaptids vocally unknown to me, it seems best to indicate that identification is not certain.
29/V/73 - parking area below km 21, R.G., 10:30 AM.
Bird called in by playback of normal song recorded near Cumboto. The bird had not been singing (although one had been heard to sing here in past days) but came in as soon as playback started; it did not sing in reaction, only flew back and forth and it occasionally gave a series call. (Although I tried I did not succeed in recording any of this.)
After some silence I played the single calls of Cut 25. Bird responded with similar calls but didn't come close, as it had with playback of normal song. Therefore apparently this call is a contact or other call without territorial significance. I then tried playing normal song of Cut 26 and bird reacted to that the same way it reacts to normal song from the R.G. region.
