You'll often hear us describe a bird species as 'red listed', but do you know what this means? The UK's birds can be split in to three categories of conservation importance - red, amber and green. ❤️Red is the highest conservation priority, with species needing urgent action. 🧡Amber is the next most critical group. 💚Species on the green list are the least critical group. #EndangeredSpeciesDay #cuckoo
