Bank Swallow Bonanza!

I was working in Port Stanley this week and took a drive to Hawk Cliff yesterday evening.  The sounds of Bank Swallows, maybe 300 or so, became more and more loud as I walked out the the cliff to enjoy the view.  I was surprised to see some of the swallows fly up to others perched at a hole in the cliff, bite onto the wing of another, and pull them to the ground below, feisty!
