Sitting in the garden with cat at dusk, watching bats circle overhead. Goddamn I missed this in winter. Saw a cuckoo today from about 10m distance, not really a colorful pird but it is rare to see one because of that. Normally you just hear them somewhere in the distance. It made really loud cuckoo sounds, was probably looking for a mate. It's crazy how those brood parasites lay eggs which look almost exactly like those of the host birds but different females lay completely differently colored eggs matching their prefered host species. But the host birds also evolved the ability to detect and discard cuckoo egs which imperfectly mimicked their own which drove a host-parasite arms race leading to more and more perfect egg mimicry. Co-evolution at its finest. https://en.wikipedia.org/wiki/Common_cuckoo#Egg_mimicry
