You name the habitat and I've seen BT Pigeons in it west of the Rockies,
deciduous and conifer. I started with two in my garden in Richmond that
used a spruce for a roost and fed at my feeder. Last bird count had 22 of
them in the same tree which suggests its the source of food that counts, not
the habitat.
