I do know that they can be territorial, but that is quite a neat experience you've had :)
in all else, I believe there is a reason for everything, and I find this strangely shortly after I asked my own question of why all my nicknames recently and in the past have been connected to birds (along that line) and that we have recently rescued two birds who had flown into our house windows (one was on Christmas morning, the other was a few weeks ago. So I feel that this may also be a sign for me (seeing this post that is :P) but for you, your experience may be trying to get you out of the house and more involved with nature, the creatures are trying to talk to you and interact with you (this is what I sense.)
