Night bird

Note to self
There is a bird here on Portugal's Atlantic coast I only hear sing as midnight approaches. I love the song. I picked the song for a phone notification before I ever heard it in the wild. Hearing it at night like this is one thing I will really miss when we leave here, one thing among many, but also one of my favorites of all times. I must find out the name of this magical creature, and what she looks like so the memory of her and her wonderful call remains with me when we go.
