Familia Oceanitidae

Son aves pelárgicas, cuya longitud varía entre los 16 y 25 cm. Vuelan rápida y erráticamente a poca distancia del agua. Se alimentan de pequeños organismos planctónicos que capturan de una manera característica, poniendo las patas en contacto con el agua, dando la impresión de caminar sobre ella.

Ponen un solo huevo blanco, relativamente grande para el tamaño del ave.

- Golondrina de mar, Oceanites oceanicus.
- Golondrina de mar chica, Oceanites gracilis

I have been browsing on-line more than three hours as of late, but I by no
means discovered any fascinating article like yours.

It is lovely price sufficient for me. Personally, if
all site owners and bloggers made excellent content material as
you probably did, the web shall be much more helpful than ever before.

Woah! I'm really digging the template/theme of this site. It's simple,
yet effective. A lot of times it's very hard to get that "perfect balance" between usability and visual appeal. I must say you've done a
very good job with this. In addition, the blog loads super quick for me on
Opera. Exceptional Blog!
