House Finch Hatchlings & Owl Info

The House Finch eggs on the back of the Liberton model home have hatched. These are the first spring baby birds at Avimor that I have seen.

I've been expecting to see owl hatchlings by now. I see that Momma-Owl is sitting higher in her nest and it just may be that she is sitting on small chicks. I found this cool info on

Normally, two to four eggs are laid and incubated by the female only for 26-35 days. Young start roaming from the nest onto nearby branches at 6 to 7 weeks, when they are called "branchers", but cannot fly well until 9 to 10 weeks old. They are fed for another few weeks as they are slowly weaned. Families remain loosely associated during summer before young disperse in the autumn. Adults tend to remain near their breeding areas year-round while juveniles disperse widely, over 250 km (150 miles) in the autumn. Territories are maintained by the same pair for as many as 8 consecutive years, however, these Owls are solitary in nature, only staying with their mate during the nesting season.

I first saw Momma-Owl on the nest on March 18th so we are now coming up on the week where the owls should hatch.
