Kind of cool, kind of creepy

This morning, we looked out the back window and this is what we saw:

And that picture does not capture the sheer number of birds in one corner of our backyard. 

After watching the number increase and increase, Jacob opened up the back door to see how they would react. 

No surprise here.

What was a surprise is that within 20 seconds or less, they were back. With additional friends. 

Like I said, it was pretty cool. And yet, kind of creepy. At least to me.
