The Barn Owl is nocturnal, hunting for mice, voles and rats, taking its prey back to the nesting site. Roosts are chosen in well-hidden corners of old buildings or tree holes and cliff edges as the bird's white plumage makes camouflage difficult. It returns to the same breeding site each year to lay 5 - 11 white eggs on a bare surface, with incubation carried out by the female for 5 weeks while the male feeds her. Although their habitat is widespread, the Barn Owl population is declining and this bird has been placed on Ontario's species at risk list.
The Snowy Owl is whiter with a smaller head and yellow eyes.
