摘要: Even when animals are actively monitoring their environment, they lose access to visual information whenever blink. They can strategically time blinks minimize loss and improve functioning but we have little understanding of how this process operates in birds. This study therefore examined blinking freely-moving peacocks (Pavo cristatus) determine the relationship between blinks, gaze shifts context. Peacocks wearing a telemetric eye-tracker were exposed taxidermy predator (Vulpes vulpes) recorded. blinked during majority shifts, especially large, thereby timing coincide with periods is already suppressed. inhibited most exhibited high rates thus highly alert. Alternative hypotheses explaining link discussed.
