Bernard Forsythe maintains and monitors 15 or 20 Barred Owl nest
boxes. No Barred Owls have initiated nesting yet this year with the
exception of one pair in his backyard that receives supplemental food
every night. And that female laid a single egg and would appear to be
finished laying ! His current expectation is that nesting will be
minimal this year and quite likely a new low for his boxes. This is
entirely due to the deep and very late snow. If the Barred Owl adults
have barely been able to keep themselves alive, they will have no
physiological / hormonal signals to start nesting. Also, the females
assess the foraging ability of the males every spring. If he isn't
bringing her food now, she won't be producing eggs.

New boxes are often not used for a few years. The owls have to find
them and also select them as a good site. Nesting this year will be
minimal. On the other hand, if any occurs it will be late. If there
actually was a pair in condition to nest, but without a proper nest
site, who knows ? They might want your box. In that somewhat unlikely
scenario, you are not too late. Like a lot of projects, anytime is a
good time.
