I need some information on black-back and three-toed woodpeckers.
Specifically, do these species return to the same site or area annually
for nesting? How sensitive are they to disturbance when nesting? Do
fledglings occupy the same territory for any length of time or do they
disperse quickly?
Thanks in advance for information pertaining to the above
questions or any other important info about these species.
