Seasonal Variation in Foraging Territory of Red-cockaded Woodpeckers
P. Skorupa and R. W. McFarlane
The habitat requirements of the endangered
Red-cockaded Woodpecker (Dendrocopos borealis) must be known in
order to implement effective forest management practices for the preservation of
this species. The few published
estimates of territory size for this woodpecker are of 2 types.
Estimates derived by dividing the size of a discrete area by the number
of clans occupying that area can provide information on their minimum
requirements if it is assumed that (a) all of the habitat is suitable, and (b)
the birds are present at maximum density. This
technique has produced estimates of 26.7 and 67.7 ha per clan in 2 Texas forests
(Lay and Russell, Auk 87:781-786, 1970) and 86.2 ha per clan in South Carolina
(Beckett, EBBA News 37:3-7, 1974).
