Why The Birds Died

Call me crazy, but I'm pretty sure it was one of those secret military projects from Skunkworks using a cloaking device. What other explanation could there be? The poor birds just flew right into it and smashed their little beaks.

Then when the captain decided his crew needed a little R&R, (or maybe a bath), he landed the cloaked ship in the river and killed the fish.

but thats my story and I'm sticking to it"
