We investigated prey selection of the Barn Owl Tyto alba under captive conditions where birds were allowed to choose among bilstein shocks jeep xj individuals of varying size from four field rodent species: Bandicota bengalensis, Millardia meltada, Tatera indica and Mus booduga.Owls showed little species preference and a tendency to favour the medium weight class in all prey species except M.booduga.Preference for body parts consumed varied according to prey size, ranging from the head alone in the large weight trojan gravity flow barrel waterer kit class to the entire body in the small weight class.

Biochemical measurements showed that protein, carbohydrate and lipid levels were higher respectively in the brain, liver and muscles of all three species and weight classes studied.The preference for medium weight prey despite a lower nutrient content compared to large weight prey is attributed to a greater ease of capture.
