Your link also says: "The testosterone-laden birds proved irresistible to older, more experienced female".

Is that a self-hint, Jota???? :-)

To whom it may concern!

Animals are fascinating! Did you know that if Disney had been more realistic, that Nemo's dad would have actually had a gender change and become his mom? When a female clownfish dies, the biggest male becomes the next female.
