Only related due to the subject matter, not a part my trail. 3-4 week ago
Mass Audubon did a blog post about a screech owl staying in a box in Falmouth MA. Looks like its a Box on a cedar poll with flashing to keep squirrels and predators at bay.
on an anecdotal side note, although red-phased owls have always been the minority in the NE, I know of 4-5 individual red-phased and only 1-2 gray-phased, in and around the sites. (these do not included this falmouth owl or a gray phased that has been well documented in Rye NH.)
