NOTES ON THE BIRDS OF SOUTH-EASTERN NIGERIA.

A systematic account (with field-notes) of the birds of south-eastern Nigeria is given, based on a collection of about 350 skins made between 1946 and 1949, mainly in the neighbourhood of Owerri. The range of several species is extended by new Nigerian records and the distribution of the races of other species more clearly defined.     

NOTES ON THE BIRDS OF SOUTH-WESTERN NIGERIA.

Notes are based on a collection of 700 skins. Extensions of range include Trachylaemus p. togoensis, Prodotiscus i. flavodorscdis, Campethera n. nivosa, Bleda canicapilla, Phyllastreplms i. icterinus, Pedilorhynchus c. aximensis, Sylvia bnrin, Apalis c. caniceps, Macrosphenus concolor , and Spermophaga h. togoensis recorded from Nigeria and Apus c. strenbelii from West Africa for the first time.
Taxonomic points include reasons for regarding Centropus epomidis as a colour phase of Centropus senegalensis and Sylvietta flavixentris nigeriae as a synonym of Sylvietta flainventris.
Dates of breeding are given for many species, and nests and eggs arc described. Indicator indicator was found in the nest of Hirundo setnirufa.
The chick of Porphyrio alleni is described.     

HABITATS AND FEEDING STATIONS OF ST LUCIA FOREST BIRDS

The habitats and feeding stations of birds in six types of forest, two mountain and four lowland, are described. Just over half the species occur in both lowland and mountain forest, about half the remainder being restricted to mountain and half to lowland forest. Endemic species, of which St Lucia has more than any other island in the Lesser Antilles, occur in a wide range of habitats, and their significance is discussed in relation to current theories of island biogeography.     

NOTES ON THE BIRDS OF THE MOLLENDO DISTRICT, SOUTHWEST PERU

An account is given of the geography and ecology of the Mollendo district, Southwest Peru, followed by a systematic list of the species recorded there over a period of 16 years' residence.
The following species are recorded, apparently for the first time, from the south coast of Peru: Pachyptila belcheri, P. desolata, Florida caerulea, Butorides striatus, Bubulcus ibis, Plegadis chihi, Himantopus himantopus, Micropalama himantopus, Chaetura pelagica, Petrochelidon pyrrhonota, Riparia riparia and Pheucticus chrysopeplus .

SEASONAL CHANGES IN NECTAR-FEEDING BY BIRDS AT ZARIA, NIGERIA

Nectar-feeding of birds was recorded during a phenological study of the woody vegetation at Zaria in the Northern Guinea Savanna of Nigeria. Throughout the dry season when it is in a non-breeding state, the Scarlet-breasted Sunbird Nectarinia senegalensis concentrates on the ornithophilous plants which flower in an overlapping sequence, and exploits the smaller-flowered species less frequently. As the flowering of the ornithophilous species decreases at the end of the dry season, the range of other plants exploited increases but, in the early rains as the flowering of the indigenous plants tails off, the sunbird switches to ornamental exotics and the indigenous, shrubby parasite, Tapinanthus globiferus. The bird is more conspicuously insectivorous during the wet season when it breeds. The Pygmy Sunbird Anthreptes platura is a breeding, dry-season visitor which exploits a somewhat different range of small-flowered, mainly entomophilous species and some exotics but also takes nectar from those ornithophilous species it can exploit, as well as the chiropterophilous Parkia clappertoniana. The bulk of the breeding population leaves the district before the flowering of the indigenous plant tails off. The five other species of sunbird recorded in the district are either very rare residents or more numerous wet-season visitors and passage migrants for which records of nectar-feeding are too few to draw conclusions about seasonal changes but the wet-season visitors appear to rely on the garden exotics in the comparative absence of flowering indigenous plants. Nectar-feeding on Bombax costatum and Parkia clappertoniana, where nectar is readily accessible and present in relatively large quantities, was noted for IS species of non-nectariniid birds, some of which were regular visitors. Some examples of flower consumption probably related to nectar-feeding are also mentioned.
