“At night in the fall there are probably these little owls about the size of a soda can that weigh as much as a robin flying over [your] house and we're completely oblivious to it.” Scott Weidensaul in an interview with Terry Gross for Fresh Air, Oct. 20 2015. You can find the whole fascinating interview here.
To see these amazing owls in action, we suggest visiting Goose Pond's Kampen Road on a clear day before sunset - and visit soon! These grassland owls fly lower to the ground, and feed on small mamals - especially voles. Check out this map to see where the owls were spotted recently: http://goo.gl/maps/do6xI
