"Sumer is icumen in" at 23:59 this evening, to be precise. Still, I rather doubt that any of the 8 North American members of the Cuckoo family will be heard singing outside my window on the Solstice, lhude or otherwise. However, if I were in the desert southwest - and a bit gullible - I might hope to hear one of them go "Beep Beep!" Yes, the family Cuculidae includes cuckoos, roadrunners and anis.
We have plenty of "Wile E" Coyotes hereabouts, though. Lhude howl awoo?
