Foraging Patterns of Sympatric Hornbills during the Nonbreeding Season in Arunachal Pradesh, Northeast India

  title={Foraging Patterns of Sympatric Hornbills during the Nonbreeding Season in Arunachal Pradesh, Northeast India},
  author={Aparajita Datta and G. S. Rawat},
The diet and food resource partitioning of three sympatric hornbills (Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus, and Oriental Pied Hornbill Anthracoceros albirostris) during the nonbreeding season were studied relative to fruit availability in a foothill semievergreen forest of Arunachal Pradesh, northeast India. Hornbills fed on fruits of 49 plant species that comprised over 95 percent of their diet. Hornbill species partitioned food resources by varying the relative… 

Food items and foraging sites of the oriental pied-hornbill (Anthracoceros albirostris) during breeding season in Sungai Panjang, Sabak Bernam, Malaysia

The findings confirm the species high adaptability to disturbed habitat and the species has taken advantage of Sungai Panjang's agricultural background particularly during its breeding season.

Results are consistent with the idea that disturbance disrupts mutualisms between hornbills and some large-seeded food plants, with the caveat that role redundancy within even small and specialized disperser assemblages renders other tree species less vulnerable to loss of regular dispersal agents.

Protecting a hornbill haven: a community-based conservation initiative in Arunachal Pradesh, northeast India

Pakke Tiger Reserve (PTR) in Arunachal Pradesh harbours four species of hornbills (Great Hornbill Buceros bicornis , Wreathed Hornbill Rhyticeros undulatus , Rufous-necked Hornbill Aceros nipalensis

Phenology, Seed Dispersal and Regeneration Patterns of Horsfieldia Kingii, a Rare Wild Nutmeg

Results show a significant positive relationship between the percentage of hornbill nests that are active in a given year and the contribution of the species to hornbill diet, but the overall contribution to the breeding season diet of hornbills is very low because of poor fruit availability in most years, resulting in limited seed dispersal at nests.

Aggregated seed dispersal by wreathed hornbills at a roost site in a moist evergreen forest of Thailand

The quality of hornbill dispersal to this roosting site may be poor due to the highly concentrated seedfall, which results in high seed and seedling mortality and probably serve as agents of seed dispersal in the moist evergreen forest of Khao Yai.


This study provides a preliminary inventory of fruit-hornbill interactions in lowland dipterocarp forests of southern Thailand, allowing for comparisons across different forest types where different hornbill species perform similar roles.

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.

Food Preference of Rehabilitated Asiatic Black Bear cubs in Lowland Tropical Forests of Northeast India

Observations were made on the feeding habits of Asiatic black bear (Ursus thibetanus thibatanus) cubs during their rehabilitation program in the lowland tropical semi-evergreen forests in Pakke Tiger

Exploring Distributional Evidences and Threats to Initiate Conservation of Great Hornbill (Buceros bicornis) In Nepal

Great hornbill (Buceros bicornis) which belongs to Bucerotidae family is a big bird found in the Indian subcontinent and Southeast Asia. It is recorded as Endangered in Red data book of Nepal,



Foraging characteristics of an assemblage of four Sumatran hornbill species

It is suggested that the four hornbill species in the study partition food resources by food type and/or feeding location, as well as maximum crop sizes of diet species significantly influenced the number of feeding hornbills.

Fruiting Phenology and the Conservation of the Great Pied Hornbill (Buceros bicornis) in the Western Ghats of Southern India 1

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.

Hornbill abundance in unlogged forest, selectively logged forest and a forest plantation in Arunachal Pradesh, India

The responses of hornbills to selective logging were determined by comparing their diversity and abundance in five habitats classified according to logging history, and great hornbill was the most common species overall and its abundance varied across habitats, being highest in unlogged forest.

Population Fluctuation in Sulawesi Red-Knobbed Hornbills: Tracking Figs in Space and Time

It is hypothesized that Sulawesi Red-knobbed Hornbills may play an important role as agents of rainforest because they appear to track fig produc- tion over potentially large distances, and include a mix of other rainforest tree species in their diet.

Foraging Patterns and Resource Utilization in Seven Species of Bats in a Seasonal Tropical Forest

Competition for fruits was more important than competition for nectar and pollen in determining species diversity in this bat community, and a combination of the timing of plant—reproductive behavior and bat foraging characteristics promotes long—distance outcrossing and seed dispersal.

Seasonal Variation in the Quality of Fruits and Diffuse Coevolution Between Plants and Avian Dispersers

The significance of highly rewarding winter fruits for the evolution of some physiological and behavioral traits among overwintering dispersers points to the existence of a closely coevolved system involving the latter and the assemblage of winter-ripening mediterranean evergreens.

Ecological and behavioral consequences of digestion in frugivorous animals

The postingestional effect of seed size and mass and nutrient composition on fruit profitability are reviewed. It is emphasized that profitability results from the interaction between fruit

Abstract: Slash‐and‐burn shifting cultivation, or jhum, the predominant form of agriculture in the hill tracts of northeast India, is believed to have caused considerable loss of forest cover in the

Characteristics of vertebrate-dispersed fruits in Hong Kong

ABSTRACT Hong Kong has a native angiosperm flora of approximately 1800 species, of which 27% (482 spp.) bear fleshy, presumably vertebrate-dispersed fruits, including 76% of the 337 tree and shrub
