Every fall, during the months of September and October, tree swallows congregate in the lower Connecticut River during their southward migration. In the evening, the birds fly from up to 25 miles away to roost on a island called Goose Island, that is 100% covered with an invasive plant, a large reed called Phragmites australis. At dusk they converge near and over the island. The giant flock of birds create an amazingly graceful "ballet" in the sky and eventually form a massive funnel just after sunset and plunge themselves down into a communal roost in the marsh for the night. It is truly an amazing sight to see. If you have been lucky enough to experience it in person, you know these pictures and video clips don't do it justice, you really must be there to see and hear it yourself.

So thank you swallows, for making our transition back to Connecticut a little easier. It's nice to know we have our own wild things right here in our backyard. We'll see you again next year.
