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.

Drastic Drop in Baby Brown Pelicans: Blame El Niño?

By Becky Oskin, Senior Writer | June 04, 2014 03:12pm ET

An endangered species success story is suffering this year, perhaps because of El Niño.

California brown pelicans almost completely failed to breed at their nesting sites in Mexico this year, surveys have found. Scientists are reluctant to blame any one cause for the drastic decline in fuzzy-headed baby pelicans, but a similar drop in breeding numbers struck during previous El Niño events

"Over the years, we've seen that during an El Niño, their breeding effort goes way down," said Daniel Anderson, a University of California, Davis wildlife biologist who has monitored California brown pelicans for 46 years. Overfishing of sardines and habitat loss could also be hurting the pelican population, Anderson said.
