SHORT COMMUNICATION SIGN LEFT BY BRUSHTAIL POSSUMS AFTER FEEDING ON BIRD EGGS AND CHICKS
and day-old domestic chickens (Gallus gallus) during a captive feeding trial. Differences in feeding sign left by possums of differing sex, age class, and hunger were slight or absent. Possum feeding trial remains were also compared with remains of North Island robin (Petroica australis longipes) an...
