Abstract
Studies on foraging rhythms of house crow (Corvus splendens) for 30 and 60-minute durations were studied in the Khurrianwala from December, 2004 through April, 2005 on citrus, (Citrus reticulata), sunflower (Helianthus annuus), unripe ziziphus (Ziziphus jujuba), guava (Psidium guajava) and jaman (Syzygium cumini). For all observations, citrus and sunflower were the most intensively depredated food crops in both the morning and evening sessions, depicting the predilection of crows and thus, largely responsible for economic losses. Highly significant correlations were obtained for the morning and evening foraging activities 0.686** for 30-minute duration, and 0.836** for 60-minute duration, depicting the severe depredations for a higher time interval, particularly in the late evening hours.
