Who knew they were such good neighbors?
Really, Henry, these birds scare the crap out of me.
They are roosting all around my house and I kept thinking it was an omen or something until I trusted the wisdom of a Google search.
So, they are the ultimate anti-bacterial bird - their diet curbs most diseases - even their poo is supposed to be somewhat anti-microbial.
They also remove the deadwood off of trees with their roosting - (incredibly helpful, I have several trees that have died).
There is also no reason to be afraid of their congregation, they are only after dead meat.
Hooray for the scary birds!
