Not a Bird

But it does fly -

Bonus Catch

This is why it is important to watch where you are going -

This guy was most likely running-swimming-flying away from a tuna/wahoo/sailfish and 'we' in a boat just happened to be passing in front of it's escape route. It launched from the water and straight onto the cockpit superstructure.

After a 'thud', I checked the weather deck and this guy fell through to the back of the boat.

Cool fish - from the wingspan and lower fins, gliding along looks like it is an easy affair for this guy.

Pretty colors on it - after some quick pics, I let this one go back to the water.
