The Howie and Holly Nestbox Cam

Welcome to the 2020 nesting season! Keep track of the owls on the live cam below.

Howie and Holly are Western Screech-owls in northwest Tucson, Arizona. Screech-owls are sexually dimorphic in size so the bigger owl you see is the female, Holly and the smaller one is the male, Howie. When it’s cold they both puff up and it’s hard to tell by size but you can see a bit of a white arch on the back of Holly’s head.

Owls will use nestboxes year-round for roosting and during breeding season for nesting. Check out the timeline on the right side of the page to see if you missed anything.

This live-feed camera is part of Tucson Audubon’s Desert Nestbox Initiative and is made possible by donations.

5.1.2020 We can all use a funny clip right about now. Check out this lizard sitting on Howie’s head!

April 29, 2020. Three eggs have been removed from the nestbox by the parents. We weren’t able to actually capture how they do it but shells were found under the nestbox. We have 2 eggs remaining in the nestbox to which Holly is still tending to normally.

April 25, 2020. Normal incubation is 26-34 days for Western Screech-Owls. It has been 40 days for Howie and Holly and, unfortunately, it looks like a failed clutch. It is unusual for all of the eggs to fail without any extreme events so it must have been an internal issue. Western Screech-Owls are known to nest again if the first clutch fails and this often happens in a new location. We will leave this live cam up while we observe their behavior in response to the failure.
