Mystery spot

 

This might be tough, but can you guess where this photograph of a Common Green Darner (Anax junius) was taken?

Here's a more helpful clue:

 

It might also help to tell you that I was in San Francisco today.

Could you tell that these pictures were taken at a baseball field?  All of them were taken at AT&T Park on 27 August 2015.  The dragonflies were a nice bonus to an exciting baseball game!

In the past —  see the post from 1 July 2012 — I've mentioned that I have some fun when attending baseball games by keeping track of bird and insect sightings.

Today the most visible dragonflies were Common Green Darners.  They were actively feeding along the edges of the field.  I'm not sure exactly how many individuals were in the Park, but I photographed at least three at one time:

 

Although distant, I also photographed one tandem (male/female) pair of green darners:

 

And today I added one new "ballpark species" to my list.  I didn't get a photograph, but I saw one Flame Skimmer (Libellula saturata).  I'd love to hear about your bird and dragonfly sightings at baseball games!
