members also heard. In succeeding days, the bird spent increasing amounts of time away from the yard. Sept 15. Another toucan nearby, but never came close, never saw or heard any interaction. [Specimen proved to be a male! My first thought was that calling and weak singing was that of a 120-year male, but it is clear this behavior can be shown by a F. Unfortunately do not know if she was 1st yr or adult.] Sept 16-23. Toucan present, chipping continues, but enters longer, as chipping of lower frequency. No song, pair-reinforcement note, or other vocal contact between mates. Neighboring toucan shows up, chips irregularly, but there are no close approaches. No pairing acts observed heard. I suspect neighbor is a F. When one flies, the other can move off in same direction, providing my individual (A) moves to NW. This may be low-key territorial interaction.
