Just birds on rocks. But what birds?

They're Black turnstones. I put off posting this because I didn't have much hope of identifying them; just dark birdd-shaped specks in the distance, but then that one caught in flight was a dead giveaway.

It didn't look like there was much to be found on those bare rocks, but the turnstones were busy. Their eyes are better than mine.

Pájaros y piedras. ¿Pero qué son esos pájaros?
No tenía muchas esperanzas de identificarlos a esa distancia; solamente eran pájaros oscuros, y tan lejos. Pero el diseño de las alas y la espalda cuando vuelan era la clave.
Son Arenaria melanocephala, conocidos como vuelvepiedras. En Latín, pájaros de arena con cabeza negra.
Desalojan moluscos y otros organismos marinos de las piedras, usando sus picos cortos y en forma de cincel. (De AllAboutBirds)
No parecía que hubiera mucho para encontrar en esas piedras, pero los vuelvepiedras estaban muy ocupados; tienen mejores ojos que nosotros.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.
Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
