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.

SCIENTISTS IN THE AMAZON “SENTINEL” BIRDS WARN NEIGHBORS OF THE DANGER

Experts have found that tropical forests some species of birds help others to avoid falling into the clutches of predators at settlement in less safe areas.

Usually birds of the same species flock together, but on Amazon reign other orders, and there can be dozens of varieties of birds of different colors and sizes. While such groups are quite stable. Scientists have long been trying to determine the reasons for this phenomenon, and biologists at the University of California in San Francisco succeeded.

Experts have determined that the unusual flocks of tropical forests have a special “sentinel”. Usually in the role of “guard” are the grey, shrubby esperito. They warn others of danger, for example, the appearance of hawks or falcons. Scientists have found that “sentinel” played an important role in the pack. After catching biologists more of their neighbors began to move in densely populated and safer areas.
