Abstract

Hornbills provide a seed dispersal service for rainforest trees, but the persistence of hornbill populations depends on the availability of old trees that provide cavities for their nests. The Helmeted Hornbill Rhinoplax vigil is Critically Endangered, due to both forest destruction and an inhumane illegal trade in their bill casques, yet little is known about its nests and breeding biology. Here we describe the nest tree and external nest characteristics of a pair of Helmeted Hornbills in Bukit Barisan Selatan National Park, Lampung, Sumatra, and compare them with observations of two nests of the Wreathed Hornbill Rhyticeros undulatus less than 1 km away. As in a previous study, the Helmeted Hornbill (HH) nest was in a large dipterocarp, and possessed a stump next to the entrance that the male used as a perch when feeding the female or chick. The nest entrance dimensions and bole diameter of the nest tree were much larger than those of the two Wreathed Hornbill (W1 and W2) nests. Egg laying in HH took place in February, while in W1 and W2, eggs were laid much later, between late May and July. The maximum nesting cycle of the Helmeted Hornbill was an astonishing 137 days (4.5 months), close to the minimum period (range, 138-151) for a nest of the species in Peninsular Malaysia. This may be longer than the nesting cycle of the Wreathed Hornbill, but additional data are needed.

Abstract

The use of social media in Indonesia is changing traditional trading methods in the country, and this extends to the sale of protected wildlife such as raptors. Between January and December 2015 the authors monitored 38 Facebook groups and recorded 2,471 individuals from 21 diurnal raptor species being offered for sale. Most were juveniles, and the Black-winged Kite Elanus caeruleus was the most frequently offered species. The peak of raptor trading was in July and August, coincident with the breeding season of most raptors as many birds are taken as nestlings. Regular scrutiny of social media sites and increased punitive action by law enforcement agencies, and public awareness campaigns by governments and NGOs, are desperately needed to eliminate this audacious market for illegal trade.

Abstract

Urban landscapes have depauperate avifaunas, but there have been few studies of urban bird communities in Southeast Asia. Domestic cats can attain very high densities in urban environments, and are known to have detrimental effects on local avian assemblages. The aim of this study was to describe the urban bird assemblage of Kuching, an equatorial city in Borneo, and to investigate its potential relationship with the abundance of cats. The density of birds and domestic cats was examined in ten discrete urban areas from November 2014 to April 2015 using line transects. A total of 1,844 bird observations were made, involving 27 species. Bird species richness and diversity were negatively related to cat density (R2 = 0.41 and 0.43, respectively), but cat density did not significantly affect bird density (R2 = 0.032). Bird species richness was strongly correlated with the size of urban areas (R2 = 0.76, P = 0.001) suggesting that larger areas offer additional habitat or niches (e.g. street trees, parks, waterways), which in turn support more species. Reduction of habitat heterogeneity and type of surrounding matrix, as well as the presence of abundant introduced predators may play important roles in structuring the composition and population dynamics of this urban bird community. Urban areas do have some biodiversity conservation value, but the challenge is to enhance this value through better planning.

Abstract

Repeated aerial diving, and aerial ingestion of small schooling fish, probably Bilih Mystacoleucus padangensis, by Brahminy Kite Muhammad N. Janra

Abstract

Many papers have been published on the food and feeding behaviour of the Brahminy Kite Halistur indus. At Singkarak Lake, West Sumatra, a Brahminy Kite was observed repeatedly diving from 10-15 m in the air to snatch small fish from the surface of the water, and eating them in the air. The prey was probably Bilih Mystacoleucos padangensis, a fish species endemic to the lake. Only one fish was taken on each dive, so it was undoubtedly more energy-efficient to eat the prey on the wing than to take it to a perch after each capture, though potential kleptoparasitism by other raptors may have also selected for this feeding behaviour.

Abstract

Counts of the invasive Common Myna Acridotheres tristis and Javan Myna A. javanicus were carried out in Kuching, the capital city of Sarawak, Borneo, and in surrounding suburbs, over a period of 30 months from July 2013 to December 2015. Ten areas were sampled each month using 3 km-long line transects. Combining all 30 months, a total of 3,913 mynas were counted, of which 75% were Common Mynas, and 25% Javan Mynas. Population densities were estimated at 0.78 and 0.72 individuals ha-1 for Common and Javan Mynas, respectively. The Common Myna was widely distributed in Kuching and suburbs of Kota Samarahan division, whereas the Javan Myna was confined to metropolitan Kuching. The distribution of these two species was thought to be influenced mostly by food and nest site availability.

Abstract

Indonesia ranks second to Brazil in the number of globally threatened bird species. The Sumatran Laughingthrush Garrulax bicolor was formerly abundant but has suffered population declines due to trapping for the pet trade, and now considered endangered. Despite knowledge gained from in-situ and ex-situ captive rearing programs, little is known about the biology and ecology of the species. Our study sought to redress this by undertaking a field study of its home range size and behaviour. One group of five individuals was located in North Sumatra province and observed from strategically positioned hides over three weeks to estimate the size of its home range using Minimum Convex Polygons (MCP). In total, we collected 70 GPS points representing either sight or call records. The inhabited area covered 1.07 km2 with the most remote edge points being 1.9 km apart. The group occasionally joined mixed species feeding flocks which included Chestnut-capped Laughingthrush Rhinocichla mitrata and Black Laughingthrush Melanocichla lugubris.

Abstract

The White Cockatoo Cacatua alba is endemic to the North Molucca islands and is considered Endangered mostly due to unsustainable levels of trapping for the pet trade. Little is known about its breeding biology in the wild, except that it nests in tall trees during the early part of the year. We made brief observations of two active nests of White Cockatoos on Halmahera and another on Ternate in February and March 2014, and estimate the egg laying dates of two of these nests as mid-October and mid-November. Combined with other data, the breeding season appears to extend from October to May or June. All three nests were visited by Blyth’s Hornbills Rhyticeros plicatus, a species which occurs throughout North Maluku, as well as New Guinea. One nest was subsequently abandoned. In September and November 2014, we observed two active nest cavities of hornbills, one of which was inspected by a cockatoo, and the other, approached closely by cockatoos. Both hornbill nests were reported to have been used previously by White Cockatoos, suggesting that the two species may either share or compete for the same nest cavities. Sharing of cavities may be facilitated by partly non-overlapping breeding seasons, as Blyth’s Hornbill reportedly lays eggs from August to October in the region. However, as the nest cycle of both species is c.4 months, it is possible that early nesting pairs of one species may attempt to usurp nest cavities occupied by the other species. The potential for nest competition may be exacerbated on small islands where deforestation has reduced the number of nest cavities available for hole-nesting species.
