Bowdoin Wildlife Preserve

I did go to the Preserve on Sunday and hoped to get a couple of 'bird shots' with the Tamron 150-600. I don't know birds and I will let friends like Ethan and David provide the names. It was an extremely windy day (19-25MPH), but I gave it my best shot(s).
One Question did come to mind as I drove the 15 mile circuit of the marshes and lake. Why do they call this a Preserve and still allow people to come and shoot the birds at seasonal times??
Here you go. Enjoy

Looks like it has a bug in its beak!

Had a great day and hope that your Sunday was just as enjoyable.
