Hope, the female peregrine falcon at the Cathedral of Learning, laid her third egg of the season early this morning March 12 at 2:10am. Thanks to Nicole Brant for posting a comment with the date and time.
Hope will probably lay a fourth egg but the timing may be longer than the last two. Her last two eggs were laid 62 to 64 hours apart, but her fourth egg last year was more than 90 hours after the third. Will she follow that pattern this year?
Watch the Pitt peregrines here on the National Aviary's Cathedral of Learning streaming falconcam. Expect a fourth egg some time between Wednesday evening and Friday morning.
