Start of egg-laying in relation to latitude and elevation among Swedish Starlings Sturnus vulgaris in 1988-2003
The Starlings Sturnus vulgaris breeding in sixteen nest-box groups, three in northern and thirteen in southern Sweden, were monitored in 1988-2003. Date of the first egg was found to correlate with both latitude and elevation when all sites were included (13 degrees of latitude; 5-430 m elevation)....
