A sorta hidden joke
When Bostic shows up at High Island in Texas, he pushed through the crowd, prompting two British birders to comment, "Only an American could turn birding into a competion!" Bostic then gives them the Jersy salute. Just a little ironic considering it was the British who coined the term 'Twitcher' to some one obsessed with birds, meaning some one twitches with anticipation when they hear of a new bird. A funny read is Bill Oddie's Little Black Book of Birding detailing the extreme nature of their obsessive competition.
"Six trips? Sounds to me like somebody doing a Big Year."
"Maybe I just love to watch birds."
