are 5 kinds of bat in Bugbrooke, the Common Pipistrelle, the Soprano
Pipistrelle, the Brown Long-Eared bat, Daubenton’s bat and the
are unlikely to be able to distinguish between the 2 Pipistrelle
Pipistrelle is very small (around 5g before hibernation) and flies
above head height. It is the most common bat.
Brown Long-Eared bat flies a couple of feet above vegetation &
bat flies close to water (like a small hovercraft), taking insects off
the surface. They are mostly seen on the canal, but they have roosts
in the trees in the churchyard. It is a medium-sized bat.
Noctule is a large bat (Starling size) and less usual to see, but is
the first to emerge in the evening. It takes a straight flight path,
high & fast.
tend to roost in newer houses under wood facings, soffits etc.
Also in trees, in abandoned Woodpecker holes and cracks where
rot has set in.
long-eared bats roost in roof spaces of older houses.
bats roost under arches/bridges/tunnels and in tree holes.
often the occupants of the house are quite unaware of the presence of
droppings are like mouse droppings, but when squashed in a tissue they
go down to dust.
tend to be used like hotels. The bats gradually move from one place to
another for no apparent reason. They often stay only for a week or
two. Quite often a roost may just have one bat in it. Where there are
many bats it may be a roost used by females and their young. These
quite often “chitter”.
are a few fallacies about where bats choose to roost. Ivy on trees is
no indicator that it is a good home, as it tends to be cold beneath
it, and bats like warmth. Equally, barns are generally too cold.
all have quite a large range. Pipistrelles around 3km when foraging, and Daubenton’s have been tracked 6km before being
lost, but presumably they make the return journey during the same
you do the sunset survey with a view to doing the sunrise survey, you
may not have a clear idea of the direction the bats are coming from.
If you would like to find a roost to watch for the sunrise survey,
watch in a field or another open area rather than in your garden.

attract bats, use a “batterpult”, a simple catapult, to ping maggots
or mealworms into the air. You can feed the bats while watching them
hunt!” Nick Baker’s British
