tical with elsewhere, apart from this peculiarity and keeping more to cover. It is seldom seen on Uvea to perch high on a dry bare twig or tree and call as elsewhere, generally selecting a tree, teak or otherwise, with leaves and good cover and perching close in under or in the leaf canopy calls from there. It is difficult to pick out at such times and generally speaking, more is heard than seen of the species, though it is often seen in flight when departing after being alarmed or disturbed by presence of observer. On Uvea this species parasites Pachycephala I believe. At certain times when ♀ Pachycephala gives a call which seems to excite and attract ♂ Pachycephala in numbers Cacomantis almost invariably appear silently and remaining still and silent and watching the goings on of Pachycephala. These are probably ♀ Cacomantis looking for prospective foster parents. If humans mimic this call they can almost always attract Cacomantis if any are anywhere about, though a very sharp lookout has to be kept to see the approaching bird as it comes very carefully and silently and low down and is apparently watchful and wide awake and appears to be peering here and there all the time. Observer may be wrong but gathered an impression that the Uvea bird showed some plumage differences to Mare Is. MAYR QUESTION:- Parisitizes which species? A. On Uvea Lalage much and though I did not actually see any fostering young I believe Pachycephala much. Myiagra is also parasited to a limited degree. Zosterops lateralis may be parasited but observer believes only to a limited extent. Lalage for certain and Pachycephala I believe are the 2 main
