What are bats up to August and September?

A lot can be happening in August.  Bats born in June that have survived will be fully weaned and catching their own aerial insect food.  Those born late may still be suckling.  Some maternity colonies have dispersed whilst other will remain together throughout the month. Much depends on the species and the influence of weather.  The initially wet summer will have meant that a number of colonies are later than in warmer, drier years.

Bat colonies remain extremely sensitive to disturbance at this time.  Young bats occasionally become disorientated and it’s at this time of year when they are most likely to be found inside houses or grounded.

At six weeks old, the young bats begin to catch insects for themselves and no longer need their mothers’ milk.  The summer maternity colonies begin to disperse and bats may move to mating roosts.

The summer’s maternity colonises are now dispersing as the mating season gets under way. Bats are also now able to concentrate on feeding and building-up fat reserves for hibernation. This year’s young bats are now largely independent of their Mothers and feeding themselves. Nevertheless they still occasionally get in to trouble.

If you find a grounded bat or are concerned about a bat’s welfare, then please refer to the Bat Rescue tab above.
