No really...I mean it.... DUCK! Whew...that was close...Oh wait.. Did you think I meant 'duck' as in the bird? Sorry, my bad! Maybe I should have been more clear and said 'Cover your head quick!' or something? Maybe RUN AWAY!?! You see, in our yard in PA we have some 'attack birds'. Well, more like very protective parent birds. A few years ago Mom put up a bird house, not really expecting anything to take to it. Ever since then, every year without fail a pair of these guys has made it their, and their babies, home for a few months of the year. Mom thinks they are purple martins, but isn't 100% sure. Whatever they are, they sure are pretty little birds...and VERY protective if you get to close to their..oh boy - DUCK! ...uh, sorry...what was I saying? Oh yeah....They are very protective and if you get to close to their house they will start dive-bombing to try and chase you away. It's a bit unnerving having a bird screaming ...
