The huge numbers of purple martins at Nimisila Reservoir abandoned their
pre-migration roost last week. Larry Hunter of the Portage Lakes Purple
Martin Association boat rides let me know that an owl discovered the
roost. The numbers went from 20,000 to 10,000 and then 250 in succeeding
nights. The owl was spotted over the roost each of these nights and was
identified by shape, size, habitat and behavior as a short-eared owl.
