Sunset / Sunrise Survey
This survey is ideal for you if you don't have previous bat surveying experience. It is also a perfect opportunity to get together with family/friends and discover bats and other wildlife in your local area.You can take part any time up to September but the next month or so is the best time for locating maternity roosts using this survey method. 

You can download a form by clicking on the image below which will also take you to more information about the survey (including videos of sights to look out for) and the online data entry form.

Brush up on your species ID skills with our bat detecting quiz
Test your ability to identify bat species from their calls heard on a tuneable (heterodyne) bat detector.

Tips are provided on separating the species, so if you don't get it right first time then this should help you correctly identify the species if you try the quiz again, or next time you're out in the field with your bat detector.

Click here to try the quiz.

Take part in the Field Survey or Waterway Survey
These two surveys require you to have some experience of identifying bats using a heterodyne bat detector.

The Waterway Survey (August) is simpler so is a good one to start with if you are relatively new to bat detecting. It involves walking along a 1km stretch of waterway and counting passes of Daubenton's bats as they skim low over the water. Click here for more information.

The Field Survey (July) involves counting passes of common pipistrelle, soprano pipistrelle, noctule and serotine (the latter species tends to occur in the southern half of GB only) using a heterodyne bat detector while walking a transect in a 1km square, so this survey requires a bit more experience.

Repeat sites up for grabs!
On the Waterway Survey and Field Survey pages you will find lists of previously surveyed sites that need taking on by a new volunteer - see the "Survey sites up for grabs!" section in the above links or click on the following links to go straight to the list of available sites: Waterway Survey sites / Field Survey sites. Why not take a look and see if there a site near you that needs taking on? Please contact us at nbmp@bats.org.uk if you would like to take on one of these sites, or feel free to contact me directly using the details at the end of this email.

"Baton-passing scheme" - help available from previous volunteers at a number of sites
Some of the repeat sites are in our "baton-passing" scheme, which means the previous surveyor has offered to accompany a new volunteer for their first survey at the site in order to show them the route and provide tips on the survey and species ID methods. Information on these sites is available in the above links or you can access the information directly here: Waterway Survey "baton-passing" scheme sites / Field Survey "baton-passing" scheme sites.
