Five fuzzy owlets: the brood of 2025

The View. The owls have set up housekeeping in Terry’s Owl Box again this year. This is the sixth year he has been recording their nesting and rearing behavior. He has been kind enough to make this year’s videos and his comments available to us here at the lab. Updates will be posted at the top of the page as they come in.

The Data. Every year, Terry has recorded his observations regarding egglaying, hatching, and fledging. The data, including the first eggs of this year, can be found here.
