Nests and Breeding Behaviour

Nests and Breeding Behaviour

Positive relation between numbers of Purple Herons breeding in southern France and Sahel rainfall index for Sept-Oct.

2 ordinary and 1 melanistic chicks in nest of Micronisus gabar in 1976.

More eastern captive breeding sites start later in Bugeranus carunculatus.

Notes from 10 hours observing at nest of Halcyon senegaloides in Dec 1999.

Notes on breeding and food in captivity.

Early breeders in more sheltered areas than later and it is an active choice by these despite not actually making a nest but carrying eggs and young on feet. Study at Crozet Island.

Data from 41 nests of Vanellus coronatus over 18 months.

5 nests and 20 singing males near Luxor, Egypt in May 2000.

A review of the status of all colonies of Red-footed Booby Sula sula of 2 colour morphs and Masked Booby S. dactylatra.

Activity at new colony of 900 nests at Lake Naivasha, Kenya. Breeding primarily Apr-June.

1974-2001 study. Northern bred 6 weeks earlier and were more successful. Species and sexual differences related to morphological and dietary differences.

Most Bank Cormorants breed at 3 with a few at 2. Most Cape Cormorants breed at 2.

Forest edge and gap species enhanced by logging. Trapping and foot surveys used. More egg-laying at seasons of higher rainfall.

Many basic data on nesting habits of Calicalicus rufocarpalis.

Not polygamous as is the related Seychelles Warbler A. sechellensis. 12% of territories had unmated helpers. There was some capability of dispersal between patches of suitable habitat.

28 days and various notes on chick behaviour and plumages given.

Comprehensive notes on breeding of this species where ca 600 birds found at Lake Ol Bolossat in central Kenya Jan 1997- Dec 1998.

Pair of Golden Eagles seen Jan 2000 and nest with 2 young found.

Notes on 13 tree species used in nest linings by Aquila verreauxii. Most have known medicinal uses or a strong smell.

38 occupied territories of Aquila verreauxii monitored and 17 more in surrounding area.

Descriptions and many notes on voice and breeding in captivity.

Detailed notes on Cisticola galactotes at Kazungula. 2 isolated populations appear to occur in Zimbabwe.

Notes, including illustrations, of nests of Ploceus xanthopterus

62 nests of Lagonosticta nitidula checked and 9 were parasitised by a Vidua species. Currently uncertain which Vidua is involved.

Nesting data for Ardeola rufiventris and Ixobrychus minutus.

Francolinus levaillanti breeds Aug – Mar and production averaged 2.6 chicks per brood. Hunting season should be 15 Apr to 15 July only.

First captive breeding in Britain known of this species but probably of mixed races. Brief description of young included.

Females have long absence (av. 19 days) just before laying. Males less (av. 8 days) before first incubation stint. Function and energy and lipid relations discussed.

Notes especially on breeding (8 nests found) of Adamawa Turtle Dove with records over 19 years.

Pterocles namaquus is an opportunistic granivore feeding on ephemeral plant seeds. Starts breeding 3-5 months after seed is set and continues into next rainy season when food abundance is low. Other factors, such as predation pressure must play a part in timing of season.

278 nests over 4 seasons in northern Cape Province. Suggestions that juvenile recruitment may be too low to maintain population locally.

A single bull seal eating Morus capensis fledglings at Mulges Island attacked from underneath swimming birds.

Notes on a nest of Tachybaptus ruficollis in Boland, Western Cape.

Detailed data on breeding of Francolinus sephaena studied over 5 years in 1980s.

3 finches were more successful in raising own young than those of parasite. Parasite faired best in usual host but was raised by the others.

On Aride no seasonal variation in clutch size (1.04 eggs) in bad year but increased in good year. In both, breeding success declined through season. Birds seem to sacrifice egg and clutch size for earliness of laying and old birds lay as early as possible.

2 pairs in centre of Windhoek in Nov 1997.

Notes on breeding Trachyphonus erythrocephalus.

First captive breeding of Coracias cyanogaster in Britain. Notes on breeding given.

Notes on behaviour.

Notes on dynamics of 5 birds of Urolestes melanoleucus in captivity while nesting.

Notes on a nest site (DS and MH) and a record roost of 250 birds (GT) of Telacanthura ussheri in baobabs in Zimbabwe.

Nest with 3 young found in Dec 2000. Description of chicks included.

Compares data with other sugarbird and sunbird species from study in Mpumalanga Province.

Four nests found 1997-1999. Various basic data included.

A small population seems established on Dyer Island.

Notes on breeding ecology of Carp’s Tit Parus carpi and Ashy Tit P. cinerascens. Both lay smaller clutches and feed young less frequently than north temperate congeners.

Few natural nests found suggesting they are limiting. Other data mainly from captive birds.

8 nests found, all in holes in grey mangrove trees.
