NATURE’S SECRETS

World’s Weirdest Events, 8pm, BBC2

FOLLOWING the success of Nature’s Weirdest Events, Chris Packham (pictured) presents a new series exploring the bizarre, the freakish and the mind-boggling . . . Packham begins, in his own inimitable style, by looking at how the sun’s rays can kill birds in midflight, and how a monkey learnt to give first aid. It’s fascinating stuff.
