Homes for Bats and Birds

Jim, who works for The Conservation Volunteers, has been updating us on the latest work being done on London's oldest Nature Trail.

This January, the conservation volunteers put up the new Woodcrete Bird and Bat boxes purchased by the Gardens team.

These boxes are used by most conservation organisations as they are tough, durable and easy to clean. They are made of a mix of wood pulp and concrete, so are impervious to attacks from woodpeckers, crows, jays and magpies who will attempt to raid the nests for eggs and fledglings.

We have put up four bat boxes down around the Nature Trail meadow. This is a good area for bats (probably pipistrelle bats) as the pond is nearby, and this along with the meadow is a good source of insects - the bats main food.  The bats can roost in the boxes and come out to feed from dusk onwards.

Bats live in colonies, so the boxes are all put close together, unlike boxes for birds, which have separate territories.  

Four blue tit boxes have also been put up along the trail to join the other six great tit boxes that are already there. The difference between the two boxes is that the blue tit box has a smaller hole, thus excluding the larger great tits, who will oust the smaller blue tits given the chance.

All of these boxes will provide very useful nesting and roosting sites for birds and bats, and they will help to increase the overall biodiversity and educational value of the Nature Trail.
