摘要: We quantified vigilance during feeding in the Zenaida Dove aurita, a tropical species with stable pair-bonds and year-round territoriality. Both males females decreased proportion of time spent vigilant by 30% when their partner compared alone. This reduction was achieved through increasing length inter-scan duration, while scan duration remained constant. No evidence found for coordination between pair members. The equal investment male female Doves might be related to mutual benefits long-term pair-bonding.
