Roost sites, reproduction & life cycle

summer roost sites

The maternity roost at Seething Wells is occupied from late spring and sometimes until October. It is one of only four maternity colonies recorded within the London Region over the last four years.

Young bats are suckled for several weeks and are fully weaned and able to forage for themselves at 6 to 8 weeks.

cracks and crevices

Sometimes bats roost in the pipes along the wall or in other areas on the site; join non-breeding females during the summer at a communal roosts, or  join maternity colonies.

 Autumn is when mating takes place; active males continue to seek out and mate with females throughout the winter.

There used to be around 30 bats with an extended extended family at the sites along the river. Twenty years ago they were 200 strong but that's another story.
