After leaving BP to head for my bus at MTS of course looked to the nest box and what did I see a falcon, really white breast, sitting on the rail of the box, watched for 5 minutes or so and then it took flight. Put down the binocs and it headed to the Rogers sign, followed the flight and then looked back with the binocs and there was one sitting on the ledge of the nest box and did not look like the first one I saw. Think there are or is a egg in there and there are alternating now. But not an expert and ony guessing. TPC will let us know when.
