Social and ecological factors influencing vigilance by northwestern crows, Corvus caurinus
Article Abstract:
Research designed to established whether groups of beach-foraging northwestern crows look out for predators and changes to steal from conspecifics is presented. It was found that scanning or vigilance behaviours were affected by more than group size and the danger of predation. There were significant effects of factors including time of day, breeding status and foraging ability.

Effects of ecology and prey characteristics on the use of alternative social foraging tactics in crows, Corvus caurinus
Article Abstract:
A study was conducted to examine the factors influencing the use of food-producing and food-stealing behaviors in northwestern crows, Corvus caurinus. The result reveals that no ecological factors, like group size, temperature, time of day and season, or individual characteristics influenced the probability of retaining the prey.

Lateralized tool use in wild New Caledonian crows
Article Abstract:
A study conducted to observe the lateralized tool use in non-primate, New Caledonian crows, Corvus moneduloides, is presented. All the crows exhibited a significant preference of side in holding the lateralized tool, a characteristic pronounced previously only in humans and chimpanzees.
