An eagle owl called Kaln lived for 23 years at a sanctuary in Gloucester, England. For that entire length of time, its handlers believed it was a male. Then, according to Vincent Jones, creator and trustee of the sanctuary, it laid an egg

The egg wasn’t fertilized, Jones informed Live Science, so Kaln will not get to mom a chick. However still, it was a huge surprise to all of Kaln’s handlers.

” I believe he was simply as surprised as we were,” Jones stated. [Photos: Salmon-Eating Owls Revealed in Stunning Images]

Sexing owls is challenging, due to the fact that males and women outwardly have basically similar bodies, according to a research study released Jan. 24, 2008, in the Journal of Genetics Unlike mammals and other animals, there’s no apparent distinction even in between their genital areas.

Plus, Jones stated, his sanctuary has no interest in the biological sexes of the birds it takes in. The majority of them are saved from lives as animals or captive working birds, he stated. And the sanctuary has no interest in reproducing captive owls, just restoring them.

” We have 46 birds,” Jones stated. “If they have the habits of a male, we state they’re male. If they have the habits of a woman, we state they’re female.”

Normally, according to the National Aviary, Eurasian eagle owl women lay up to 6 eggs throughout a month-long duration in late winter season. [Whooo Knew? 10 Superb Facts About Owls]

Kaln never ever did that though in his 23 years at the sanctuary, Jones stated.

” He’s constantly revealed indications of being a male,” Jones included.

Much of the male birds in the sanctuary “imprint” on their human handlers and treat them as mates, he stated. And throughout reproducing season, “Kaln constantly wishes to bonk whatever,” he stated.

Even hereditary tests do not constantly reveal a clear difference in between male-sexed owls from female-sexed owls in lots of types, according to that 2008 paper. Female-sex birds have Z and W chromosomes, while male-sex birds have 2 Z chromosomes. However those chromosomes can be comparable enough that they’re challenging to differentiate. The authors of that paper particularly attempted to differentiate the genes of male and female Eurasian eagle owls and stopped working.

The egg hasn’t altered how the sanctuary views Kaln, Jones stated.

” It’s no various than individuals. There’s no distinction in between male and female. We’re all people,” he stated. “Kaln is a person. He’s a really unique person. Now we state he’s a gamine.”

The bigger issue is that around the very same time the bird laid its egg, it started acting “depressed” and showing some health concerns that ended up being unassociated.

Today (June 27), nevertheless, Jones stated that Kaln has actually appeared more active and positive.

” Which’s what actually matters isn’t it? The health of the owl,” Jones stated.
