Seasonal and annual variation in brood attendance, prey type delivered to chicks, and foraging patterns of male Common Terns ( Sterna hirundo )
The study took place over 2 years (1990 and 1991) on a concrete breakwater located 1 km offshore on Lake Erie near Port Colborne, Ontario. Ten male Common Terns (Sterna hirundo) in 1990 and 12 in 1991 were radio-tracked by boat or car during the chick-rearing stage. Concurrent behavioural observatio...
