They're back!
Yes, that's right, cuckoos are definitely back in the UK - I heard at least three over the weekend. Did you hear any? Why not let me know by leaving a comment below...
So to celebrate the arrival of cuckoos, spring and a whole host of other migrant birds this weekend, here's a cracking shot of a male cuckoo for you. Enjoy!
David Kjaer snapped this image and it's one of thousands of images from RSPB Images - take a look and find your perfect spring time shot.
