Barred Owl Eggs Could Pip Today
Keep your eyes peeled for a pipping egg on the WBU Barred Owl Cam; the pair’s first of three eggs, which has been incubating since March 5th, is scheduled to begin hatching today! At any moment the soon-to-be hatchling could start to make the first pip, or initial break, in its eggshell. Watch cam.
After pipping, owl chicks can take as much as 12 hours to make their way out of the egg. If things go as planned and all three eggs hatch, we’ll be spending the next 4–5 weeks watching three closed-eyed, hungry Barred Owl chicks grow into fledglings and prepare for their emergence into the wilds of Indiana.
In the meantime, enjoy the sights and sounds of this rural forest by listening to the Barred Owls’ distinctive hooting calls and checking out what’s new on the menu for these generalist foragers—we’ve already seen an earthworm and a vole in the nesting box this year.
