Granivory among birds is specially prevalent in pioneer or early stages of the ecological succession (Wiens & Johnston 1977), where plants are selected for high and rapid reproductive rates thus producing large seed crops (Leck et al. 1989). True granivorous birds show an array of behavioural, morphological and life-history adaptations to exploit open and unpredictable habitats, together with morphological and physiological adaptations for eating seeds (Wiens & Johnston1977). These adaptations… Expand
Differences in the bird community between a regenerating area and a native forest in Southeastern Brazil
ABSTRACT Restoration of degraded areas might be assessed via faunal communities of a particular region, and birds are one of the taxa most suitable in such assessments. This study evaluated theExpand
Assessing the bird guild patterns in heterogeneous land use types around Jammu, Jammu and Kashmir, India
Land-use sprawl in the Himalayas has caused the conversion of natural habitat into human-modified habitats, thus degrading ecosystem health. Adaptation of birds to changing physical environment canExpand
The Relationship Between Bird Communities and Habitat
Abstract To assess the impact of habitat disturbance on birds in the Yuksom–Dzongri trekking corridor in western Sikkim, India, the relationships between bird community attributes—including migratoryExpand
Cross-taxon congruence in a trekking corridor of Sikkim Himalayas: surrogate analysis for conservation planning.
Summary The use of surrogate taxon in conservation planning has become an important tool in the recent years. Woody tree, bird and butterfly diversity indices were used to investigate their potentialExpand
Different responses of avian feeding guilds to spatial and environmental factors across an elevation gradient in the central Himalaya
TLDR
The results showed that richness for all birds and most guilds displayed hump‐shaped elevational trends, which peaked at an elevation of 3,300–3,600 m, although richness of ground‐feeding birds peaked at a higher elevation band (4,200–4,500 m). Expand
Dietary guild composition and disaggregation of avian assemblages under climate change.
TLDR
How climate change projected by 2100 may transform the world's avian assemblages is explored by modeling environmental niche-based changes to their dietary guild structure under 0, 500, and 2000 km-dispersal distances. Expand

GRANIVORY IN NORTH AND SOUTH AMERICAN DESERTS: RODENTS, BIRDS, AND ANTS'
TLDR
The extinction of a marsupial family, Argyrolagidae, which appears to have been the ecological equivalent of the rodent granivores, Heteromyidae, may have caused the differences in granivory. Expand

TLDR
The need of stable underground refuges and predation risk in the winter period seemed to be the mam factors constraining rodent foraging activity in the man-made ecosystem studied. Expand

TLDR
Patterns of variation in insectivore diversity for shrub and forest habitats in tropical and temperate areas are consistent with the hypothesis that species diversity increases with seasonal stability of microhabitats selected for foraging and is correlated with the stability of resources in those microhab itats.

Treefalls and the Distribution of Understory Birds in a Tropical Forest
TLDR
It is suggested that treefall gaps contribute to the structural heterogeneity of the forest and influence the composition and richness of the bird community. Expand
Tropical wet forest treefall gaps and distributions of understory birds and plants
TLDR
The patch dynamics of understory birds and fruiting plants in treefall gaps and intact forest sites are examined to determine the importance of gaps in structuring a Costa Rican tropical wet forest community and suggest that gaps may be important sources of fruit during periods of fruit scarcity.
