I liked the last line:

"I don't know of other birds who do this in the wild," he said.

errrrrm, can't say I know of many people who try different disguises in order to catch different types of birds. I wonder if that could have something to do with it!

What an odd, if interesting, article! Sounds more like something that Homer Simpson would get up to, he he he!
