Using Demography Online (DemOn)

DemOn is an online application for inputting and managing nest record and ringing data.

Once you’ve signed up to NRS and started monitoring nests, how do you send your observations to the BTO? The answer is DemOn, an online app for inputting nest records as well as doing reports and summaries, such as a tally of the nests you’ve monitored by species. DemOn is also used to input bird ringing data.

Go to Demography Online

Logging in to DemOn

Simply visit the DemOn homepage (it’s a good idea to bookmark it), input your My BTO username and password and press the green ‘Login’ button. If you can’t remember your My BTO details, here’s what to do:

  1. go to the password reset page, input your username or email address, then input the 'Captcha' code that appears before pressing the orange button 'E-mail new password';
  2. look in your inbox for an email that begins 'Password request for account…' and open it;
  3. the email will tell you your username, so make a note if you’ve forgotten it;
  4. if you’ve also forgotten your password, select the link in the email to reset it, press the ‘Log In’ button on the page that appears, then input a password of your choice twice and press the 'Save' button;
  5. go to the DemOn homepage and try to log in again. If you still can’t then it’s probably because you haven’t yet signed up to the Nest Record Scheme.

Help getting started

Before you start using DemOn please have a read of the quickstart guide. If you need further help, open the ‘Help’ menu at the right of the green menu bar and select one of the options. You can also get help from other DemOn users by joining the DemOn Facebook Group and you can always apps.demon [at] (contact us).

Nest recording in a group?

DemOn is based on 'accounts', like bank accounts except for storing data. When you sign up to NRS you are given a personal DemOn account but you can also have one for a group, which is a great option if you do nest recording with others and you all want to see and manage the same data. For example you might have a group account called ‘Nunnery Nature Reserve volunteers’.

If you want to set up a group account, please apps.demon [at] (contact us). Or if you want access to an account you think already exists, contact the person who has set it up as they can grant access. 

When you have access to more than one DemOn account you should still log in with your own My BTO username and password. Once logged in, you can switch between accounts by pressing the blue ‘Change’ button in the top-right-hand corner of the screen.
