Our personal one here in The Hothouse at the moment is the emerging summer sounds of nightingales, who also sing throughout the daylight hours, the next door's cockerel - clearly not on the correct timer - who calls throughout the late morning, their goat, various parrots, the donkey-birds (see a post last year), swallows and various chorusing frogs.
This small green one, hidden in the pampas grass was making an electronic beeping noise. It emerged onto the terrace much to the cat's interest, and I picked it up to have a closer look.
Isn't nature a totally incredible thing? That colour, the eyes, the toes. It just sat there calmly while we stared at it, amazed that such a tropical-looking creature had appeared in our European garden.
