Hawk Creek Wildlife Center’s breeding project. Time elapsed barn owl egg hatching.
From the Cornell Lab of Ornithology in the USA:
The Barn Owls that took up residence in a new nest box on a Texas ranch are showing promising signs for the upcoming breeding season. The male has been bringing prey animals to the nest in displays of courtship, and both birds have been cozily tucked in their nest box almost every day for the last few weeks.
We’ve seen them mate a few times, and we hope to see them lay their first eggs sometime before the middle of April. Watch cam.
