Millions of baby blue tits will be taking to the air for the first time this month. It's a bit of a damp start for many with all the rain showers hitting the UK at the moment.
Incredibly only about one in ten will see their first birthday. They're an easy target for predators like sparrowhawks and many fall prey within the first few days of leaving the nest. Blue tits have broods with up to ten chicks, so these high losses rarely have any impact on the tit population from year to year.
