«Feather Atlas» — a practical guide to identifying the birds around you by looks, calls, habitats and seasonal movements. <a href="https://birdpedia.co.uk/">birdpedia.co.uk</a>.
The site gathers species portraits, voices, migrations, field notes and a photo gallery. Clear tips help you notice a bird in the garden, a call in the trees or something overhead — and know where and when to look again. Recently added species and field notes are updated regularly.
If you need a specific bird rather than a general overview, start with the full bird list or the recently added species.
