A pelican in New Zealand

Notornis, 13 (4), 204-217

R.J. Scarlett (1966)

Article Type: Paper

The discovery of sub-fossil pelicans in New Zealand is reviewed, and the conclusion reached that, owing to their larger size, the New Zealand birds were a distinct sub-species, which is here named Pelecanus conspicillatus novaezealandiae.


















Food habits of pukeko (Porphyrio melanotus Temminck)

Notornis, 13 (3), 133-141

A.L.K. Carroll (1966)

Article Type: Paper

An examination was made of the contents of 298 pukeko gizzards collected between February 1963 and August 1964. Specimens were from Rotorua, Canterbury and Nelson-West Coast. Food consisted almost exclusively of plant material, most important in all three districts being grasses and sedges. Predominant grasses were Poa spp., Glyceria spp. and Anthoxanthum odoratum; sedges, Scirpus spp., Eleocharis spp. and Carex spp. All parts of these plants were eaten. Leaves of clover (Trifolium spp.), seeds of dock and sorrel (Rumex spp.), seeds of willow-weed (Polygonum spp.) and seed-heads of rush (Juncus spp.) were also frequently taken. Animal material was sparse. Spiders (Arachnida), beetles (Coleoptera), flies (Diptera) and other insects predominated. Earthworms (Annelida), peripatus (Peripatus novaezealandiae), wood-lice (Isopoda) and fragments of lizard and bird bones were occasionally found. Although grit occurred at all times, a greater weight was taken in winter and early spring.
