BirdTrack is an exciting project that looks at migration movements and distributions of birds throughout Britain and Ireland.

Time, skill and support
There is no minimum time commitment. Spend as much time as you like recording the birds you identify.
You need to be confident in the identification of the birds you record.
Videos and training courses are available to help you develop your bird ID skills.
About BirdTrack

BirdTrack allows volunteers to store and manage their own personal bird records, and uses these to support species conservation at local, regional, national and international scales.
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.
The project is a free and convenient way of storing your bird records online, and lets you keep up to date with what others are seeing, view the latest trends, and contribute your data to BTO science.
Record on the go with BirdTrack Apps
Log your bird sightings anywhere in the world - Learn more about our mobile apps.
- 'Smart' species list for adding sightings, containing the birds most likely to be seen in that area.
- Sync all your existing BirdTrack places and upload everything into your BirdTrack account.
Go beyond just data entry and use the app to:
- View a map of recent sightings.
- View target species that you haven't seen this year / ever.
- View your year and life lists.
Delve into your records
Use the 'Explore my records' function in BirdTrack to view your data in a range of exciting ways.
- View your life and year lists at global, regional or local levels.
- View maps of all your birding locations.
- Extract the data as tables and graphs.
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.
- Please read our full statement on the use of auto-id tools for more detail and clarity.
Code of Conduct
Volunteers must follow BTO’s Code of Conduct. This code applies to our staff, our members, and volunteers, including surveyors and participants in the Ringing and Nest Record Schemes, (hereafter referred to collectively as ‘staff and supporters’). It applies to all BTO activities, whether online (including meetings and events, telephone, letter, and email) or offline (any face-to-face interaction). We've also written some guidance for volunteer fieldworkers, which will help beginners in particular.
Migration blog
Your BirdTrack data allows us to follow the arrival and departure of migrants through the seasons.
What's been seen this week? How will the weather affect migration next week? And which species will be arriving near you?

Project timeline
- 2002 Migration watch started, with the initial aim of mapping migration
- 2004 Re-named BirdTrack and expanded to cover all seasons
- 2013 BirdTrack apps released on iOS and android
- 2014 BirdTrack global portal released, allowing data to be entered from anywhere in the world
- 2019 BirdTrack moved to a single site handling both British/Irish records and those from elsewhere in the world
- 2021 Additional taxa added to BirdTrack: Amphibians, Butterflies, Dragonflies, Mammals, Orchids, and Reptiles can all be recorded
- 2022 Link to iRecord set-up to facilitate a daily flow of non-avian records from BirdTrack to iRecord

Contributions and findings
- Long-term changes in the migration phenology of UK breeding birds detected by large-scale citizen science recording schemes
- Robustness of simple avian population trend models for semi-structured citizen science data is species-dependent
- Estimating species distributions from spatially biased citizen science data
