NOTES: Part A: (Cut#: 55A; Time: 1400-1440; Background Sounds: Zosterops borbonica mauritianus) HPF 200. Entirely one male who responded acutely to playback with many calls - and also many of the soft [contact calls]. Male and female together with some of the aggressive "buzz and kek" calls. He came many times and searched for the source of the calls. At one point he pulled a caterpillar from the underside of a Sideroxylon puberulum [sp] tree's bark [brown with darker markings] [from under the bark]. He took some considerable time "breaking it up" by banging it against a branch. The flight is undulating but less so than C. newtoni. The wings come in close to the body but not so tightly as in C. newtoni. Field annotation included.
Part B: (Cut#: 55B; Time: 1445-1500:1515; Background Sounds: Acridotheres trista, Pycnonotus jocosus) HPF 200. Per S. Temple - there often were unpaired males remaining in an area - in territories of paired birds. This was just such a male - as for the entire recording and extensive playback we never saw a second individual nor a female. At the extreme end there was a female heard calling [and a second male calling distantly]. Had this male been mated the female would have come and I would have heard the rip or zip call. Also he would not have kept returning to playback. "Mated" males become habituated more readily and cease responding. Note: at the extreme end a female came into sight but the male likely was her mate and different from the one I was recording. Note on the undulating flight being similar to C. newtoni - at the extreme end there is a female heard and seen and it is likely the male calling with her is her mate and different from [ie the pair from the territory] the lone male I recorded for so long - the calls are different.
