Birds living around the site of the Chernobyl nuclear accident have 5% smaller brains, an effect directly linked to lingering background radiation.

The finding comes from a study of 550 birds belonging to 48 different species living in the region, published in the journal PLoS One.

Brain size was significantly smaller in yearlings compared to older birds.
