Abstract: Vegetative parameters of 14 autumn blackbird roosts in central Ohio were measured. Common characteristics of roosts included young trees (x = 11.30 years, SD = 2.86), high densities (x = 7746 trees/ha, SD = 5328), and thick canopies. Plant communities were adapted to moist sites and included American elm {Ulmus amencana), silver maple (Acer saccharinum), green ash (Fraxinus pennsy/vanica), red maple {Acer rubrum), sugar maple (Acer saccbarum) and black cherry (Prunus serotina). Tree density, twig height, and twig index were significantly related to numbers of birds per ha.
