As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Motherless Male Zebra Finches Prefer Same-Sex Mates

By Joseph Castro, Live Science Contributor | June 17, 2014 09:32am ET

Male zebra finches prefer to form lifelong pair bonds with other males if they're raised by their dad alone, new research shows.

This mate choice is likely the result of males "imprinting" on their fathers, researchers say.

Zebra finches are socially monogamous, meaning that each bird pairs up with a single mating partner for the rest of its life. These tiny birds are also known to form lifelong same-sex pair bonds, though scientists aren't sure what factors influence the sex of the birds' partner choice.
