A frankly excellent website for identifying bird species, particularly useful if you're like me and trying to do so years after having seen them 😁 It's a really neat interface that makes narrowing down species pretty simple, though their filtering sometimes goes a bit haywire and it would be great to be able to have a few more photos for some species (there is a bias towards more colourful/dynamic poses, rather than simple identification patterns, juveniles, or instances where one gender has a dull colouration).
