The effects of predation risk on the use social foraging tactics
Article Abstract:
The effects of predation risk on the use of social foraging tactics by tree sparrows, Passer montanus, is studied experimentally. The result suggests that in tree sparrows, the increased predation risk is due to several mechanisms like stochasticity in food supply and risky sites used by individuals possessing low reserves.

Passerine migrants respond to variation in predation risk during stopover
Article Abstract:
A study is conducted on small passerine birds during migratory stopover to determine whether their behaviour was related to variation in risk of capture by migrating birds of prey. The results suggest that predator avoidance behaviour might limit foraging opportunities during stopover by restricting habitat use.
