Wallace, Dean et al.,
The Atlas of the Breeding Birds of Tennessee (Nicholson 1997) provides
the following egg & nestling dates for Great Horned Owls in Tenn.:
egg dates: 2 Jan - 20 Mar.
nestling dates: 9 Feb - 24 May
So, nestlings in mid Jan. would certainly be a notable extension of the
known nesting period & should be verified.
