Sunset - Sunrise SurveyDo your bit for bats this summer

You may have sat in your garden on a warm summer evening and watched bats flitting around, but have you ever noticed that there are far fewer bats than there used to be?

The Bat Conservation Trust has been counting the UK’s bats since 1997, with the help of thousands of volunteers. We need to understand what is happening to our bat populations so that we can work effectively to conserve them - this ongoing monitoring should provide an early-warning system. Bat monitoring takes place in a wide variety of locations all over the UK, with volunteers counting bats as they emerge from their roosts, fly along waterways, or even while they’re hibernating in caves and tunnels!

The Sunset-Sunrise Survey is aset-Sunrise Survey is aset-Sunrise Survey two-part survey that helps us to find more bat roosts to monitor. You can take part in either survey or both, but the more help you can give us, the more chance you have of finding bats...

The Sunset Survey couldn’t be easier! Simply spend the evening in your garden or local open space and watch out for any bats that fly past. Sunset Survey couldn’t be easier! Simply spend the evening in your garden or local open space and watch out for any bats that fly past. Sunset SurveyRecord how many bats you see, which species they are (if you think you know) and, most importantly, which direction they are flying from.

The Sunrise Survey involves going out just before dawn to look for bats swarming before they return to their roost (bat swarming is when Sunrise Survey involves going out just before dawn to look for bats swarming before they return to their roost (bat swarming is when Sunrise Surveyseveral bats circle around a structure or tree). You can either stand outside a structure if you think that bats might roost there, or walk a short route that takes you past structures that bats might use. If you have already done the Sunset Survey and saw bats flying past, you should walk in the direction from which most of them seemed to be coming.

Try to carry out one or both of the surveys anytime in June, July, or August. This period is when bats form the largest colonies and is also the best time to see them swarming as they return to the roost. The best thing about this survey is that you don’t need any equipment or experi-ence, and you may not even need to leave your back garden.

Preparing for the surveysEquipment needed: Survey form or notebook Pencil/pen Torch Alarm clock!

If you are planning to do both surveys, try to do them within a week of each other - bats can move roost frequently in the summertime, although they are creatures of habit and return to the same roosts year after year.

Walking a routeYou can start at your own doorstep or you may prefer to travel to a nearby location if you think it will increase your chances of finding a roost. Plan a route (up to 1km long) that is safe to walk and takes you past houses, buildings, bridges, barns or old trees that bats might use. Make sure that the route sticks to public rights of way and does not pass through private property or dangerous areas, and walk the route at least once during daylight hours to familiarise yourself with it. Please ensure you read our full H&S guidelines at www.bats.org.uk/pages/sunset_sunrise_survey.html or included with this form if you received it by post.

Surveying a structureIdentify the structure that you would like to investigate. This could be any of the following: Your house (or a neighbour’s) Another building, such as a barn, outhouse or garage, on your property A public building, such as a church, town hall, community centre or school A structure on public land, such as a bridge, stone wall or tunnel A tree on land with public access

Make sure that you have permission to be there if you need it; don’t survey a private house or business premises unless it is your own. If it is a public building or a tree in a public place, let the person who manages the site know what you are planning to do - they may even want to take part in the survey too!

Which bat is it?There are eighteen species of bat in the UK, but you are most likely to see one of six different species. Here we provide a basic guide to identifying these bats, although it’s entirely possible that you may see something a little more unusual!

Species (pictures not to scale) Wingspan Wing shape Typical flight pattern Summer roosts

Pipistrelle19cm

- 25cmNarrow wings

Flies about twice the height of aver-age person, makes lots of downward swoops. Irregular flight & makes lots

of turns.

Buildings, esp modern houses & larger buildings. Also in tree

holes, behind ivy & in bat boxes.

Daubenton’s24cm

- 27cmBroad wings

Often just above water or flying along hedgerows in wide arcs or cir-cles. Steady height & flight pattern.

Bridges, tunnels & culverts close to water, also old trees overhang-

ing waterways. Occasionally in old stone structures.

Brown long-eared23cm

- 28cm

Wide wings with broad ends, can usu-ally see the distinc-

tive ears

From ground level to treetops. Fairly slow, fluttering flight & often hovers.

Oftein in older buildings with large roof spaces, esp churches & barns. Also tree holes & bat

boxes.

Leisler’s26cm

- 32cmNarrow & pointed, similar to noctule

At treetop level, fairly straight with shallow dives & gradual rises.

Tree holes & bat boxes but also old or modern houses & indus-

trial buildings.

Serotine32cm

- 38cmBroad, rounded tips, wings look very dark

Lower than treetops, along edge of trees & hedges, can hover & pick

insects from leaves.

Buildings, esp houses built around 1900 with high gables,

also churches.

Noctule32cm

- 40cmLong & quite narrow

with rounded tips

Very high above treetops, fast straight flight with deep wing strokes

& steep dives.

Mainly in tree holes but some-times in buildings. Also roost in

tall chimneys & bridges.

If you see bats returning to their roosts they may be using the flight patterns described above, but when bats are swarming they will not usually be flying in this way.

Completing the formPlease fill in your details in the first section - if several of you took part then nominate one person to complete it on behalf of the group. Also do please tell us how many volunteers took part and record their ages, if you know them.

You can use any of these landmarks to help you describe where you looked for bats, the start and end locations of your route or where you saw bats swarming: Street name and town/village Church Ancient feature (castle, fort) Public land (park, common) Public building (school, swimming pool, village hall)
