dc.description.abstract A 3 year (1971, 1972, 1978) study of spring and autumn inter-island movements of blackbirds across the Lake Erie archipelago showed that not all nights were unidirectional. Daily nights between roosting and feeding areas occurred in many directions and only the net movements were north in the spring and south in the fall. Each year the spring movements started between March 1 to 17 and ended between May 5 to 23 with an average period of G5 days. Fall migration usually occurred in October and November. Patterns of flight roosting and feeding appeared to change wThen small flocks united with larger flocks. Canada may provide late-summer and early-fall feeding places for blackbirds nesting in northern Ohio. en_US
