Map Į4. Collection localities in New Brunswick, Canada of Hylota ochracea .

of H. ochracea occurred in the nest contents which usually consisted of rich decaying organic material with bones, fur, owl pellets, portions of dead prey items (mice, squirrels, small birds), and often the contents had a strong urine smell. This species was also found in the nest contents of the great horned owl. Majka et al. (2006a) reported this species from the nests of the boreal owl, Aegolius funereus richardsoni (Bonaparte) and northern saw-whet owl, Aegolius acadicus (Gmelin) in Nova Scotia. Interestingly, H. ochracea was also common among decaying vegetables inside a plastic compost bin, which in some respects mimics the conditions found within a tree hole occupied by an owl. Only one adult of H. ochracea has been captured in New Brunswick in a habitat other than a tree hole or other enclosed situation; in drift material along a river margin. Adults were collected in May, June, and September. Collection method: sifting.
