Radiation causes smaller brained bids

An interesting study around Chernobyl (the site of a big nuclear accident) of 550 birds of 48 different species found that the birds in the area have 5% smaller brains.

Brain size was significantly smaller in yearlings compared with older birds. Smaller brain sizes are thought to be linked to reduced cognitive ability.

Interesting to note that insect diversity has also fallen.
