Wait Up Guys!

I took a nice walk with my friend Laurie today and we stopped along the way so I could get a few potential Blips (all of my friends and family members are fortunately used to this by now).

I snapped a few shots of some Canada geese, but right when I thought I was done they took off to join a huge flock of birds flying overhead. Of course I had to try to capture it.

I'm not sure how good a job I did, but here it is.

How do they know to just spontaneously take off like that? It never ceases to amaze me.
