Attacked by a bird!

I was walking down the street under a low hanging tree and this little guy pecked me on the head twice and was going for more until I batted him away. Nerd that I am I had to Google this little shit. i remembered he was yellow breasted and aggressive. This is what I found:

"The western kingbird is very aggressive and will attack hawks, crows, and ravens which come close to its nest. Humans have also been dived upon by this bird, however, the outcome is more surprising than harmful."
