There were several hundred blackbirds in that flock.  They were in the sky flying en mass.  They were tightly grouped and flying together not changing the distance between them much; thus flying as a mass.  I have no idea where they are migrating from or where they are going.  I just notice them coming through this area twice a year–fall and spring.  They are small blackbirds.  Sometimes they will stay in the area a day or two.  I just marvel how they keep so close together when they fly as a flock.  They are just a (???) one of many mysteries of nature to me.

They could have been swallows.  I saw dozens alight on that wire and swirl above.  I never saw swallows migrate before.  It was early morning and they were over a mile away from water.  If I had to guess, they were cliff swallows.  I spotted them going through the “back way” into town.  I was surprised to see them.  Now is the time I usually see flocks of small blackbirds come through.  I still saw a hummingbird feed on my nectar today.  At least one has not decided to migrate.  Temperatures have fallen–the seventies.  Summer does not end for another three weeks.  There is no doubt Autumn has come already.
