  • Title
    Nesting of Lesser Whistling-Duck Dendrocygna javanica (Horsfield, 1821) (Aves: Anseriformes: Anatidae) and broken-wing distraction display at Kamrup District, Assam, India
    Type
    Journal Article
    Description
    We observed 13 nesting attempts of the Lesser Whistling-Duck during 2011–2014 at Rani, Kamrup District in Assam, India. Failure in egg laying by the ducks and nest raiding by Grey Mongoose were recorded, while the breeding success was 38.5%. For the first time we witnessed broken wing distraction display exhibited by this species as an anti-predator strategy, which we have recorded here.

    On the breeding of the Slaty-legged Crake (Aves: Rallidae: Rallina eurizonoides) in Nilambur, Kerala, southern India
    Type
    Journal Article
    Description
    The first sighting and breeding of the rare Slaty-legged Crake Rallina eurizonoides (Aves: Rallidae) from Nilambur, Kerala, southern India is provided. The clutch size was seven eggs and three chicks fledged out of it. The total incubation period was 20 days, a first report for this species.

  • Title
    Some aspects of the ecology of the Indian Giant Squirrel Ratufa indica (Erxleben, 1777) in the tropical forests of Mudumalai Wildlife Sanctuary, southern India and their conservation implications
    Type
    Journal Article
    Description
    The Indian Giant Squirrel Ratufa indica, an endemic species to India, is widely distributed from the evergreen to moist and dry deciduous forests of Western and Eastern Ghats and the central Indian hills. We studied its population distribution, activity, feeding, ranging and nesting behaviour across three major habitats in the tropical forests of Mudumalai Wildlife Sanctuary, southern India, during 1998-2000 to manage the species effectively. Extensive survey of the three major habitats—tropical moist, dry deciduous and dry thorn—in the sanctuary shows that its distribution is continuous in moist and dry deciduous forests with good canopy contiguity and patchy along riverine areas in dry thorn and dry deciduous forests with sparse trees and broken canopy. Density estimates using 55 direct sightings from 199 km line transects show a mean of 2.9 (plus or minus 0.313) squirrels/km2. Daylight activity and feeding patterns assessed through 24,098 minutes of focal sampling reveal that animals feed and rest equal amounts of time. The diet constitutes seeds, bark, petioles, leaves and fruits from 25 plants, with Tectona grandis as the principal food source (41%). Its home range size varied from 0.8-1.7 ha with a mean of 1.3ha. Nesting characteristics assessed through 83 nests surveyed along 54km transects showed that the squirrel uses 15 of the 33 tree species found, with higher preference to Schleichera oleosa and Mangifera indica. Nest trees are significantly larger in height, gbh and canopy contiguity than nearest non-nest trees, which are attributed to better protection and escape from predators. Maintenance of diverse natural habitats and reduction in anthropogenic pressure are measures suggested for the conservation of giant squirrel populations in the study area.

    Note on breeding and parental care behaviours of albino Hoary-bellied Squirrel Callosciurus pygerythrus (Rodentia: Sciuridae) in Sibsagar District of Assam, India
    Type
    Journal Article
    Description
    A few individuals of albino Horay-bellied Squirrels along with normal gray individuals of Callosciurus pygerythrus have been observed in Sibsagar district of Assam, India. One albino female was studied in captivity. This paper presents our observations on the breeding behaviour and the parental care exhibited by the albino squirrel in captivity. The squirrel bred twice in captivity with a normal male of the same species. In both the periods, a single male baby with normal coat colour developed. Oral dose of vitamin E has been found helpful in the breeding of the studied squirrel species. The mother squirrel exhibited parental care by carrying her baby using her mouth, to a safer place during danger. However, the observed phenomenon is unlike that of the cat species. Some of the habitat ecology and feeding habits of the albino squirrels have also been studied, both in natural and in captive conditions.
