The critically endangered Sichuan Hill-partridge Arborophila rufipectus occupies a restricted range in south-central China. Field surveys within this range were undertaken using line transects in 1996 and 1997. Calling males were recorded from nine subtropical forest tracts within an area totalling 1,793 km2 and consisting of primary, natural secondary and replanted broadleaf forest between 1,100 and 2,235 m elevation. The only sightings obtained were in primary forest. The mean density of calling males estimated from data collected during transect surveys was 0.48 ± 0.06 and 0.24 ± 0.16 calling birds km−2 in 1996 and 1997 respectively. There was no difference in density estimates for calling males between primary forest and secondary/replanted broadleaf forest. The principal threat to the continued survival of the species is clear-felling of primary forest, but clear-felled areas are often replanted with native broadleaf trees and records of Sichuan Hill-partridge calls in such plantations offers hope for its future survival. Forest management should be modified to make forestry practices more sympathetic to the conservation of the Sichuan Hill-partridge.

Vulturine Parrots Psittrichas fulgidus are endemic to the island of New Guinea. A review of the literature and specimen holdings indicate the species mostly occurs 500 to 1800 m a.s.l. Observations suggest the species occurs in low densities. The species is a highly specialized frugivore feeding on just a few species of figs (Ficus, Moraceae). These parrots are heavily exploited (often by destroying scarce nesting cavities) in Papua New Guinea for their feathers, used in traditional adornment. This practice might not be sustainable and four possible conservation measures are suggested: (1) increase field studies; (2) restrict transport of live birds on domestic flights; (3) replace use of Psittrichas feathers with dyed chicken feathers; (4) instruct tourists not to purchase handicrafts containing Psittrichas or other animal parts.

The evolution of 40 wintering areas of Grus grus in the south-west of the Iberian Peninsula has been studied, including the traditional wintering places of this species on its western route. Eight of these areas harboured 50% of the whole population using this route, and none of the 40 areas showed a decline in the number of birds during the study period. At present the number of cranes in each area is much greater than in the 1979–1980 winter. No geographical trends have been observed regarding the magnitude of the increase, which is closely related to that observed for the whole Spanish and Palearctic populations. Despite the emergence of some new wintering areas, the magnitude of the increase is greater in more southerly parts of the range. This may be a consequence of greater diversity and availability of food in these latitudes. The influence of enhanced international protection and agricultural food sources on the appearance of new wintering areas is discussed.

Call counts of Satyr Tragopan Tragopan satyra were conducted in the Singhalila National Park, Darjeeling, India, for three years (1995–1997). Twenty-eight groups of calling birds were recorded in 1995, 19 in 1996 and 24 in 1997 with mean density estimates (groups/km2) of 6.19/km2, 4.52/km2 and 5.46/km2 respectively. During the three years, the number of calling groups varied only on one trail. Birds called early (04h45–05h00) and the calling frequency varied from 33% to 88%. Calling peaked in April and there were significant differences in the number of groups calling in April and May in 1995 and 1996. Adverse weather conditions and wind affected calling and the audibility of calls. During spring, the Satyr Tragopan was found to be associated with both open and closed habitats. The main possible threats to this species were grazing and tree lopping. Despite some shortcomings this survey method appears to be most suitable for monitoring Satyr Tragopan.

Since i960 107 translocations of wild-caught Weka (genus Gallirallus) have occurred in New Zealand. Only four of these Weka liberations resulted in a population that persisted for more than 10 years and only one was successful on the North Island (the resultant population is now believed extinct). The reason for these failures was not known. In 1991 members of the Royal Forest and Bird Protection Society commenced breeding North Island Weka Gallirallus australis greyi in captivity for another liberation. Between 1992 and 1996 101 weka were released. We used radio telemetry to follow the fates of the first 17 Weka released in the Karangahake Gorge, near Paeroa, North Island, New Zealand to determine possible outcomes of the liberation. Only one of the 17 birds released survived until 242 days post release. Most newly released Weka were killed by predators, mainly dogs. Future Weka and flightless rail introductions should occur only in areas where predators are being removed to allow survival of released birds and production of young to exceed mortality.

We examined and compared territoriality and habitat use of two congeneric babbler species in Kirinyaga district, central Kenya, with the aim of explaining their differences in global conservation status. Hinde's Babbler Turdoides hindei is a scarce, globally Endangered species whereas Northern Pied Babbler T. hypoleucus is much more abundant and widespread, and occurs throughout the range of Hinde's Babbler. Our findings suggested a lack of flexibility in the choice of habitat by Hinde's Babbler, whose territories were centred on a scarce habitat type: Lantana thickets in river valleys or near swamps. The two species showed similar daily foraging ranges but Hinde's Babbler occupied smaller group territories, whose size was not related to group size. Aggressive encounters between the two species occurred over shared feeding grounds, all of which were initiated and won by Hinde's Babbler. Its dependence on Lantana thickets makes Hinde's Babbler highly susceptible to further habitat loss within its range.

We review the conservation history and describe the current status of the Kakapo Strigops habroptilus, a large New Zealand parrot which has been reduced to only 54 individuals through predation by introduced mammals, and is now threatened with extinction. Unique amongst parrots, Kakapo are both flightless and nocturnal. They have an unusual mating system in which females nest and raise their young unaided by males, after mating at traditional “courts” at which males display visually and vocally. Mating occurs naturally only in seasons of heavy fruiting of podocarp trees. A decline in range and abundance of Kakapo followed the introduction of alien mammals last century, and culminated in their reduction to a single breeding population on Stewart Island. Following a severe episode of predation by feral cats Felis catus, all known birds from this last population were translocated to a series of cat-free offshore islands. Adult survival on these island sanctuaries has been high (c. 98% per annum), but productivity has been low, with only six young (including a single female) raised to independence since 1982. Reasons for this low productivity are the naturally intermittent breeding of Kakapo, the low numbers of nesting females, high rates of egg infertility (~ 40%), and the early death of most nestlings through starvation or suspected predation by Polynesian rats Rattus exulans. These rats are present on both of the island sanctuaries where nesting has occurred. The Kakapo sex ratio is biased in favour of males (34:20) and only 8 of the 19 adult females are known to have laid fertile eggs in the past 10 years. Management of all remaining birds is now highly intensive, involving radio-tagging of all individuals, the provision of supplementary food, attempts to manipulate matings, nest surveillance, and protection against rat predation.

Many studies have examined differences in bird communities between shade and sun coffee plantations but less is known about how different management practices within shade coffee plantations affect bird populations. This study compares diversity and abundance of resident and migrant birds in two shade coffee plantations located in Palajunoj, Quetzaltenango, Guatemala, that differ in their farming practices (e.g. pruning schedules and fertilizer regimes) and, consequently, in vegetation structure. One plantation represents a traditional, polyculture shade system whereas the second represents a more modernized, monoculture shade system. Both plantations supported many resident and migrant birds. Bird abundance and diversity were significantly greater during both wet and dry seasons on the traditional farm, due largely to the vegetation structure resulting from the different management practices. All plantations typically classified as ‘shade coffee’ are not equivalent, much of their conservation value coming from the more diverse and structurally complex traditional polycultures rather than from the newer, monocultural systems. Coffee production techniques that affect the structural and floristic diversity of the vegetation (e.g. pruning, application of chemicals) have important consequences for birds.

Monoculture plantations of exotic Caribbean pine Pinus caribaea have been planted extensively in many tropical countries, but little is known about the bird communities inhabiting them. From October 1995 to September 1996, we compared bird populations in a 37-ha stand of mature Caribbean pine forest (planted in 1972) with an adjacent, similar-sized stand of native broad-leaved forest at Mount Saint Benedict, Trinidad, West Indies. Ten censuses, each including 10 fixed-radius point counts (25 m radius, 10 minutes duration), were conducted simultaneously during different months of the year in each habitat. Both species richness and species diversity were significantly lower in the pine forest, but the overall abundance of individual birds did not differ between the two forests. Seasonal variation in bird populations was more pronounced in the pine forest, where fewer birds (and presumably food resources) were present during the dry season. The pine forest bird community was dominated by forest edge specialists and the native forest by forest interior specialists at both the individual and species levels. At the individual level, nectarivores, aerial foragers and understorey foragers were proportionately more common in the pine forest; insectivores and canopy foragers were more common in the native forest. At the species level, more aerial foragers occurred in the pine forest and more understorey foragers in the native forest. The diversity of bird communities in pine plantations may be promoted by increasing habitat heterogeneity.

We distributed questionnaires and conducted interviews between July and November 1996 to develop a better understanding of the status and distribution of Bornean Peacock-pheasant Polyplectron schleiermacheri in Central Kalimantan, Indonesia. We found that many people were familiar with the species, that it is apparently widely distributed but rare in lowland forest, and that populations may be declining. We received reports of recent sightings of the pheasant at 23 locations in 9 survey areas. The primary threats to Bornean Peacock-pheasants are habitat loss within logging concessions and hunting. Recommendations for future conservation action include increasing the representation of lowland rainforest in Kalimantan's protected area system, specifically the proposed extension of Bukit Raya National Park, and control of hunting within logging concessions.

Domestic chickens were derived from the wild Red Junglefowl Gallus gallus. A survey of 745 museum specimens of Red Junglefowl suggests that most wild populations have been contaminated genetically by introgression of genes from domestic or feral chickens. A male eclipse plumage, which appears to be an indicator of pure wild genotypes, was found in populations in the western and central portions of the species's range, but not in the easternmost populations. Eclipse plumages probably disappeared from extreme south-eastern Asia and the Philippines prior to the advent of intensive scientific collecting (about 1860) and have not been observed in Malaysia and neighbouring countries since the 1920S. Populations exhibiting eclipse plumages were found in north-eastern India as late as the 1960s, but the dense human populations there make their continuing genetic integrity uncertain. These data suggest that surveys of wild and captive populations should be undertaken to assess the genetic integrity of this species. A re-evaluation of the conservation status of Red Junglefowl might then follow.

The extensive spatial organization of many large-bird populations is difficult to assess. We used a geographic information system to correlate vegetation structure with random sightings for four large bird species that occur throughout the 20,000 km2 Kruger National Park (KNP), South Africa. Vegetation structure was assessed visually during 1991-1992 for the 1093 2-5′-quadrats that cover the KNP. Sightings were made during 1991-1994 of Kori Bustard Ardeotis kori, Martial Eagle Polemaetus bellicosus, Lappet-faced Vulture Torgos tracheliotus and Southern Ground Hornbill Bucorvus leadbeateri, and their nest sites. As control, comparative data on ground hornbills were also available from annual aerial censuses during 1982-1994, and from records of nest sites during 1966-1996. Each species had its highest positive correlation with a different set of vegetation categories, ranging in value from the hornbill (1.13) and vulture (1.15) up to the eagle (1.32) and bustard (1.49). Nest sites had higher correlations (hornbill 1.65, vulture 2.85) than records of free-living birds. The same vegetation categories that had the highest correlations with random sightings of ground hornbills and their nests also had the highest correlations with the more extensive and systematic data from aerial census and long-term nest records. Our method of correlating vegetation structure with random data is predictive, testable and has application to the conservation management of other sparsely distributed species.

An historical study shows that the present day ex situ population of Edwards's Pheasant Lophura edwardsi, now numbering over 1,000 living specimens, originated in the 1920s from at least six different sources and c. 30 potential founders, including more males than females. Partial sequences, 820 nucleotides long, of the mitochondrial DNA (mtDNA) control-region were obtained in representatives of about half of 21 captive-reared bloodlines, identified from data in the revised International Studbook. All captive-reared birds had identical sequences. Sequences of mtDNA obtained from museum skins and samples of birds collected in the wild were slightly different from that representing the captivereared birds. The lack of mtDNA variability in the captive stock is probably due to the small number of founding females and genetic drift during c. 30 generations of captive breeding. Estimation of true extent of mtDNA sequence variability in historical and living wild Edwards's Pheasants awaits the procurement and analysis of more specimens. At least one bloodline of captive Edwards's Pheasant is polluted with exogenous genes resulting from past hybridization with Swinhoe's Pheasant L. sivinhoii. Edwards's Pheasant is more closely related to Vietnamese Pheasant L. hatinhensis and Imperial Pheasant L. imperialis than to several other taxa regarded as full species in the genus Lophura. However it is not yet possible to determine the extent of their evolutionary divergence and of their proper taxonomic rank. The initial results of this genetic research suggest that there should be efforts to (1) expand field sampling and genetic analyses of wild populations of Lophura species, (2) purge the captive stock of Edwards' Pheasant of all hybrids, (3) apply microsatellite analyses to estimate the level of genetic diversity in nuclear DNA.
