It’s not a bird. It’s a gecko.

You ask.  We answer.

We got an e-mail from a reader who forgot to sign his name.

“On all my trips to Hawaii I heard one sound that I love and have never heard anywhere else. I assume it’s a bird. I have looked up all kinds of birds and listened to their sounds and have not heard this particular bird anywhere in my research. 
It makes two sounds, kind of high pitched. Nobody seems to know what it is! Any ideas?”

Yes, we thought about it a minute—and realized it’s probably a gecko, the sticky-footed lizard that’s everywhere in Hawaii. 

The gecko sound is usually described as a clicking noise, but it often sounds like a chirping bird.
