Nesting Habitat of the Great Hornbill (Buceros bicornis) in the Anaimalai Hills of Southern India

  title={Nesting Habitat of the Great Hornbill (Buceros bicornis) in the Anaimalai Hills of Southern India},
  author={Douglas A. James and Ragupathy Kannan},
Abstract Anecdotal evidence suggests the endangered Great Hornbill (Buceros bicornis) needs mature, large old-growth trees for nesting. We tested this hypothesis by measuring vegetation characteristics at 24 nest sites in southern India and compared these data with that obtained from equal numbers of unused forest sites. Characteristics significantly different from surrounding forest at hornbill nesting sites were several properties related to size of trees. The nesting habitat characteristics… 

Breeding Biology of Great Hornbill Buceros bicornis in Tropical Rainforest and Human-Modified Plantation Landscape in Western Ghats, India

Hornbills in the modified habitat of coffee plantations used non-native tree species for nesting and foraging, indicating their adaptability to modified landscapes.

An important area for the Great Hornbill Buceros bicornis, placed as Near Threatened on the IUCN Red List, is Nameri National Park, India, within the Eastern Himalayan Mega Biodiversity Hotspot. The

Breeding Biology of the Taiwan Barbet (Megalaima nuchalis) in Taipei Botanical Garden

The overall egg-to-fledgling success rate was low at 32.8%, because of infertile eggs and failure of eggs with embryos to hatch, abandonment, anthropogenic disturbances, predation, weather disturbances, and other unknown factors.


Six nest boxes designed for the Great Hornbill (Buceros bicornis) were installed in November- December 2007 in large trees in wet evergreen forests at six study sites in the Anaimalai Hills region of

Use of tree cavities by Indian vertebrates: status of research, knowledge gaps and future conservation perspectives

Tree cavities play a key role in the structure and functioning of forest ecosystems. Though they host rich and specialized assemblages of numerous vertebrate and invertebrate species, they have

The complete mitochondrial genome sequence of Buceros bicornis (Bucerotiformes: Bucerotidae)

The newly obtained Mitogenome sequence seems to be useful for conservation biology and evolutionary studies on hornbill bird species, which would contribute to enrich the Buceros bicornis mitogenome resource and promote its biological research.

Assessment of red list of birds in China

Evaluation of the status of threatened birds in China demonstrated that three species are characterized as Regionally Extinct (RE), 15 species among them are Critically Endan- gered (CR), 51 species are Endangered (EN), 80 species are Vulnerable (VU), 190 species are Near Threatened (NT), 876 species is characterized as of Least Concern (LC), and 157 species are Data De- ficient (DD).



Nest-site characteristics and nesting success of the Malabar Gray Hornbill in the southern Western Ghats, India

The need of mature moist forest habitat for nesting by the Malabar Gray Hornbill is indicated, and relative abundance of potential nest cavities and availability of trees in different DBH classes in belt transects indicates that more cavities were formed in trees of larger diameter.

Nest site characteristics of four sympatric species of hornbills in Khao Yai National Park, Thailand

Almost all hornbills nested in cavities in the trunks of at least 13 different genera of living trees, and all four hornbill species used oval to elongated nest entrances, with the Great Hornbill preferring the most elongated entrances.

Habitat suitability for Williamson's sapsuckers in mixed-conifer forests

Williamson's sapsuckers (Sphyrapicus thyroideus) have narrow habitat and are sensitive indicators of change in intensively managed forest habitats of western North America, and habitat suitability is studied in mixedconifer forests in Arizona during 1991.

Fruiting Phenology and the Conservation of the Great Pied Hornbill (Buceros bicornis) in the Western Ghats of Southern India

To safeguard the fruit resource base for the Great Pied Hornbill, the protection of Ficus and Vitex trees from overexploitation and the conservation of forest integrity to maintain compositions and densities of the lipidrich fruit tree species utilized by the hornbill are recommended.

Conservation of large avian frugivores and the management of Neotropical protected areas

Large frugivorous forest birds are among the most endangered avian groups in the Neotropics. Despite this fact, there has been little field work on members of these groups or on other large

Nest-site selection and nesting success of three hornbill species in Arunachal Pradesh, north-east India: Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthracoceros albirostris

Nest-site availability may naturally limit hornbill populations in the area, and additional loss of nesting habitat to human activities may exacerbate limited availability of breeding sites.

An Ecological Study of Tree Cavities and Ground Burrows in Forest Stands

This paper presents an analysis of techniques used in estimating fish populations in streams, with particular reference to large non-trout streams, in the years 1952-54.

Wild Great Hornbills (Buceros bicornis) Do Not Use Mud to Seal Nest Cavities

Chemical analysis of plaster material showed that it was composed exclusively of fecal material and not mud, indicating that the Great Hornbill uses mud as plaster material to seal their nest cavity entrances.

Habitat Structure, Patchiness, and Avian Communities in North American Steppe Vegetation: A Multivariate Analysis

This work examined the effect of variation in several measures of both horizontal and vertical patchiness in vegetation distribution on bird distribution and abundance, then integrated these measures into a smaller subset of variables using Principal Component Analysis (PCA).
