Abstract

Seasonal survey of the large eared pika (Ochotona macrotis) was conducted from April 2011 to July 2012. Six field works were carried out in fifteen months for 102 full days covering
spring/summer, rainy, autumn and winter seasons in Langtang National Park (LNP), Nepal. Pikas are diurnal, herbivorous and non-hibernating small mammals that inhabit talus in alpine areas. Large ear pikas were observed in Tharepati, Phedi, Ithang, Gosainkunda, Surya kunda, Laurebina, Langtang valley, near river of Mundu village and near Langtang glacier (above Kyanging) in Langtang National Park. Pikas were occupying higher elevations only in Langtang village when observed sympatric with Ochotona roylei. Behaviour and pelage colouration varied with season. Population density was found decreased by one individual per hectare in fifteen months. Pika feeds on different plant species and also  transfers plants for hay piles. Parental care was observed in summer season
