Temperature and Growth Studies on the Barn Swallow

FoR TnE past several years the writer has conducted a series of observations and banding studies on the Bank Swallow (Riparia r. riparia) in the Lake Okoboji region, northwestern Iowa and in the Albany and Oneida Lake regions, New York State. Although these investigations have not been terminated, they have reached a stage where similar inquiries may be profitably undertaken with some closely related species. In so doing interesting comparisons can be made and deductions based on newly discovered items of coincidence or antithesis can be drawn.
