The Great Indian Hornbill is now an endangered species although in Protected Areas it is fairly common. Systematic studies have not been conducted through stray notes are available. A status survey was conducted in Periyar Tiger Reserve. It has shown its wide distribution in evergreen and semi-evergreen forests where it is found singly or in groups. It prefers old growth forest patches. Nesting take place from February to May which is related to fruiting season are figs. Nesting is done on tall old trees. Young ones are fed on figs and occasionally Lizards and even Snakes. Entrances are vertical to circular, the height of nests being 8 to 25 m from the ground. Photography is posing a management problem and in some cases the birds did not return to the nest which they generally did when they were not disturbed.

Sambar in Periyar enjoys a wide distribution in the Reserve. It is the major prey species of Tiger and Wild Dogs here. Sambar was seen singly and in groups of up to about 60 individuals. They eat a variety of grasses, herbs, shrubs and leaves and fruits of various trees. The Sambar in Periyar prefers grasslands, but usually avoids evergreen forests. They spend considerable time foraging in moist deciduous forests and 'savannah' type vegetation. Density of population of the species in the reserve (excluding evergreen tract) is estimated to be 2.1/km They spent a lot of time for feeding, mostly in the mornings and evenings. Active feeding as well as 'fluid grouping' are mostly seen in open areas. This may be an anti.predator device. Male-female ratio among adult individuals was 1 : 3.86. Males are seen with females/herbs mostly during the reproductive season - December-January. Mating was observed only once occasion. In cases, which are clearly know, young ones are born in June/July months. Males with velvet are mostly found in December-February months, though it is also found throughout the year. Sambar in Periyar is threatened by several factors' disease, poaching, tourism and grazing by domestic livestock.- Note on a Collection of Spiders from Periyar Tiger Reserve, Kerala, S. India

This study has identified new prey species of the major mammalian predators in Periyar Tiger Reserve; Nilgiri Langur, Elephant and Varanus for Tiger and Flying Squirrel for Leopard. The proportion of different prey species taken by these predators is also interesting.- Micro-histological Studies on the Food Habits of Sambar, Gaur and Cattle in Periyar Tiger Reserve in Winter

Periyar Tiger Reserve has a grassland area of about 54 km2, It supports rich herbivorous animal populations. The grasslands of this Reserve are divided into Tropical Montane grasslands and South Indian Subtropical Hill Savannah. Besides their forage value, the grasslands are potential for maintaining micro-climates for many endangered plants and animals. Forest fire is one of the major ecological factors in grasslands. Planting of Eucalyptus and other exotic plants destabilize the ecology of grasslands. Which are ideal habitats for endangered species fauna like Nilgiri Tahr, Nilgiri Pipit etc.- Birds of Periyar Tiger Reserve, Kerala, South India

A checklist of birds of Periyar Tiger Reserve was prepared. Two hundred and fortynine species of birds are recorded in the reserve. Sixty species are new records for Periyar while 3 are new records for Kerala. The lesser number of wetland birds may be due the absence of marshes and shallow water areas in the Lake. Rarity of larger birds of prey may be due to their low population in nature or the agricultural practices in the surrounding areas. This study shows that Periyar has great potential for detailed orinithological research.- Black Baza Aviceda leuphotes (Dumont) Foraging with Mixed Hunting Parties, during Noon-Not Totally Crepuscular.?

The Black Baza Aviceda leuphotes has a disjunct distribution in India, occurring in the southern Western Ghats and Eastern Himalayas where the species occurs in broad leaved evergreen forests, being mostly crepuscular and feeding on insects and lizards (Ali, 1999; Grimmet et al.,1998; Rasmussen and Anderton, 2000). Whistler and Kinnear (1936) reports specimens of the species collected from Trichinapoly in the Tamil Nadu, where the habitat is drier. The Black Baza is more active when overcast and at dawn and dusk, gathers to spend night for communal roosts in winter (Joseph et al., 2007).References
