Studies on food deficit drives of the Indian musk shrew,Suncus murinus viridescens, have been made. The time taken by shrews experimentally subjected to definite periods of food deprivation to reach the food steadily decreased upto 4 hr of deficit, and thereafter a zig-zag pattern was discernible. The duration of eating bouts increased after shrews were motivated for food for a period of upto 36 hr. The amount of food intake by shrews steadily increased when subjected to differential food deficit drives upto 12 hr and subsequently declined. No significant sexual dimorphism was observed in the differential food deficit drives inSuncus murinus viridescens.
