Hmmm, a mostly good effort Kyle. Said mostly good, cause there's one part I didn't like. The line where Bob says he'd better get back before his uncle has a cow. Not sure if that'd be an expression back then. But it's your story...
And the reason why "Little" bird would think of Gordon as its mommy is a little thing called imprinting. See, when birds hatch, the first thing they see instantly becomes their mommy to them. Doesn't matter what that thing is, a mommy bird or a cat or a human, it's their mommy and they start imitating what their mommy does.
Hope this helps, and post when the next chapter's ready.
