Spotted 4x cuckoos in a field together today (a cuckold) in the Country park. Unusual to see one, even more so to have them perch on a tree metres away from me. One was definitely a female from markings. Were chasing each other, on silent wing, diving to field for food, were not being mobbed. Also Redstart, Tree Pipit, Whinchat, Green WP, Snipe, Red Kite, Buzz, Kestrel, Stonechat, Wood Warbler etc etc
