One for the birds (day 178)

I mentioned the birds yesterday.  They are so loud and diverse sometimes that I feel like I'm surrounded, like I'm in a steam bath of birdsong.  I can't hear anything else.  What I didn't mention is that someone on twitter told me that a biologist friend of theirs says that half the bird calls are warnings.  I was shocked by this.  Could it be that what sounds like joyful songs to me are actually cries of fear?  Could I be so oblivious?  But I shook it off.  It's highly unlikely that this is the case because that would mean that a large flock of birds is not moving from their tree despite being in a perpetual state of panic.  If it's so frightful to be there surely they'd find another spot.  I have seen them panic when an eagle flies by.  The songs stop and only a few call and then they leave or go in pursuit.  Needless to say this reasoning was too long for 140 characters, so I let the tweet go unreplied.

I recorded some of the birds on Friday.  Here is an excerpt.  Hopefully I don't get a comment from a biologist telling me these birds are utterly unhappy and predicting a stock market crash.

A song for this post.
