摘要: Feeding blue tits (Parus caeruleus) increase their scanning rates as predation risk increases. However scan durations remain constant. As increases the frequency distribution of inter-scan intervals shifts from a regular (rectangular) to random (exponential) with 0.5 s constraint on minimum interval.
