Help us track the outbreak of avian influenza with BirdTrack

You can now send us sightings of sick and dead birds through BirdTrack. These records give us a real-time picture of the locations and species affected by the disease, to help us track its impact and spread.

Please remember to report all dead birds to Defra (England, Scotland and Wales) or Daera (Northern Ireland) as well, to assist in efforts to test dead birds for the disease.

BirdTrack is a free and convenient way of storing your bird records online. BirdTrack lets you keep up to date with what others are seeing, view the latest trends, and contribute your data to BTO science.

Created through a partnership between the BTO, the RSPB, BirdWatch Ireland, the Scottish Ornithologists' Club and the Welsh Ornithological Society, BirdTrack is an exciting project that looks at migration movements and distributions of birds throughout Britain and Ireland.

BirdTrack provides facilities for observers to store and manage their own personal records as well as using these to support species conservation at local, regional, national and international scales.

Taking part in BirdTrack is easy and fun. You simply provide some information about yourself, the sites where you go birdwatching, when you go birdwatching and most importantly, the birds you identify! BirdTrack allows you to store all of your bird records in a safe, easily accessible and interactive format.

    To participate in BirdTrack you just need to do the following:

    • Go birdwatching and note all the species that you see.
    • Go to the BirdTrack app and register an account. If you have taken part in any other online survey organised by the BTO then please use your existing username and password.
    • Enter the location of your chosen site(s) or select from a popular site.
    • Enter the date and time of your visit and the site you visited.
    • Record the species you saw or heard on your visit.

    We hope that you will have great fun participating in BirdTrack and that you will return to the website frequently to enter more data and to find out what's happening in your area and around the country.

    • National and regional summaries updated every night throughout the year.
    • View all of your own records and compare them with the regional figures.

    Important note about auto-ID tools:

    We recognise the growing popularity of auto-ID tools that use audio or image inputs to provide species identification, but we currently ask volunteers not to solely rely on these tools when submitting data to us.
