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.

Peacock Love Songs Lure Eavesdropping Females from Afar


Dec. 20, 2012 — Deep in the scrublands of Keoladeo National Park in northwest India, one thing was hard for biologist Jessica Yorzinski to ignore: It wasn't the heat. It wasn't the jackals. It was the squawks of peacocks in the throes of passion.

From behind the trees in the distance, she could hear a loud two-part whoop, the distinctive call that male peacocks make right before mating.

During the peacock courtship dance, a male announces that he's ready to make his move by dashing towards the object of his affection and emitting a singular squawk before mounting his mate.

"Peacocks have a number of different courtship calls, but this is the only one specifically associated with the moment before copulation, a time when the female is finally right in front of the male. It's called the hoot-dash display," said Duke University researcher Jessica Yorzinski.

The amorous peacock's signature hoot poses a puzzle for scientists.

For one, he's already got the girl.

"By that point she's already right there, checking him out. You'd think that he might not need another signal at such a late stage in the courtship process," Yorzinski said.
