Chernobyl birds are small brained
Birds living around the site of the Chernobyl nuclear accident have 5% smaller brains, an effect directly linked to lingering background radiation. Smaller brain sizes are thought to be linked to reduced cognitive ability. The effect was most pronounced in younger birds, particularly those less than a year old. That suggests that many bird embryos did not survive at all, due to the negative effects on their developing brain.
