of immature ♂ was most noticeable and quite unaccounted for. Only 2 being shot. Observer believes it very likely there is a ♀ preponderance in the young to increase the species and more rapidly populate the area, but a series of nest- lings would be necessary to prove this. The bulk of the birds probably breed in November-December and it is more than likely that numbers of birds rear 2 broods a year from what natives say. Natives themselves report increasing num- bers over the years and a wider spreading of the species, very gradual and small, almost imperceptible from year to year, but noticeable over a number of years. GERYGONE FLAVOLATERALIS ROUXI (SARASIN):- Observer very much doubts Sarasins differences, though the Uvea bird may be different (doubtful) when close comparisons are made, but I dont think the differences stated are correct. This species was confusing on Mare Island, but later I managed to sort it up. Juveniles keep the yellow washed unders in many cases till the end of the first year (skull ossifies at 6 months) but in some case loses the yellow wash very early in the first year. The eyebrow streak is an almost invari- able rule as regards age, if this is yellow the bird is in its first year, if white or grey it is in second or later years. On Mare the preponderance of these yellow washed unders in the lower ti-tree scrubs on the plains and their rareness in forest areas was doubtless due to the crow (Corvus) destroying young in forest areas. Had conditions been normal, doubtless yellow washed unders would have been just as plentiful in forest areas also and would not have
