This is funny, but I'm going to pick it apart in the spirit of gool old NT fun and humor....
Not normal behavior at all indeed! Someone had obviously been feeding them. Were you eating at the time or carrying food?
Maybe there was a nest nearby it was "defending." I suggest a simple hat as an adequate defense.
Besides, the bird was actually being nice to you. They've been known to engage in certain *ahem* "biological warfare" tactics.
That is strange, but you probably won't deny that your bed is the warmest coziest place in the house. It's also a sign you need to seal any external openings which are large enough to fit a pencil eraser with expanding foam sealant.
Good going, ya cruel, cold-hearted NT!
Care to share any incriminating details? Some of us balance our N with our T you know.
Why? Were you hungry?
Sealing for the mice should seal out the Reptilians.
Ouch. Black widow in a pile of firewood perhaps? That's a classic hideout for them.
No, but your fear and lack of understanding of it has already gotten you.
Edit: By the way, if you think you have problems now, just remember that
nature could get even scarier.
