Want an easy way to record the birds you see, and keep track of what you have seen? The BirdTrack app makes recording your sightings easy and your birdwatching more rewarding; plus your sightings support research and conservation at the local, national and global scale. Whether you want to record single sightings of those special birds or make a list of all the birds you see whilst birdwatching on a local patch you can do both from the palm of your hand. This free app links directly to your BirdTrack account on the web and acts as your digital notebook, enabling you to quickly and easily record the information you want for the birds (and some other wildlife groups) you see. With our app, you can: • Select the species you saw from an illustrated checklist of the most likely species based on BirdTrack data for your location and the time of year. • Offline mapping and observation recording, enabling use in places with no data connection. • Keep records of birds seen anywhere in the world. • See suggestions of local birdwatching places; add records for these popular places to help monitor their bird populations. • Add sightings for some other taxa groups, including amphibians, butterflies, dragonflies, mammals, orchids, and reptiles. (UK only). • View and edit previous sightings directly on your device. • View a map of recent sightings made by the BirdTrack community. • Keep track of your year and life lists, plus see lists of ‘target’ species seen by other BirdTrack users. • Option to share your sightings via social media. • Add optional information to your sightings, including breeding evidence, plumage details, and sensitive record settings to control the visibility of your records. • Sightings are seamlessly synchronised with your BirdTrack account, so you can see all your observations whether you are viewing via your device or via the website. Developed by the British Trust for Ornithology, on behalf of the BirdTrack partnership.
