The present and past naturalized distribution of the red-vented bulbul, Pycnonotus cafer, in the Pacific is described. The species was first recorded in Fiji at the turn of the century and probably arrived with indentured Indian labour. Its restricted distribution in the Fiji lslands coincides with that of several weed species which constitute its main food supply and probably limit its spread.

Incubation temperatures of the North Island brown kiwi (Apteryx australis mantelli) were studied by telemetry methods. Using the equipment described, the temperature was found to be 37.0°C on the upper surface of the egg in contact with the male’s brood patch and 35.0°C at an approximate embryo depth within the egg. Using the temperatures obtained and to test the observation that the eggs are not turned, artificial incubation of a kiwi egg was successfully carried out.

The Manukau Harbour and Firth of Thames are considered to be among the richest wading bird (sub-order Charadrii) habitats in New Zealand. Annually large numbers of four species of New Zealand’s endemic waders migrate to these, and other, northern harbours for the winter. Thousands of arctic breeding waders winter here during our summer. Small numbers of non-breeders of both these groups of waders remain here during their respective breeding seasons. There are also small numbers of two non-migratory species present. The results of twice yearly censuses of these birds during the period 1960-1975 are summarised, combined with other data where appropriate, and trends in the wader population shown. Although there has been an increase in the total number present, this has been caused by only some species, others remain stable. One species – the wrybill (Anarhynchus frontalis) – has, on the Manukau Harbour only, fluctuated significantly due to changes to its chosen winter habitat. The general habitats are described and major modifications noted. Lists of waders recorded at times other than censuses are also given. There is a paucity of long-term data on most aspects of the ecology of these species.

This paper presents the results of 1975-76 reef heron enquiry in the form of a general account of the reef heron (Egretta sacra) in New Zealand, summarised locality reports with two maps and a discussion of the present status of the species.
