I saw a single crane yesterday just east of the boat launch area, feeding in the low marshy area, around noon. I also saw a great blue heron very near the crane, which I at first mistook for another crane. Friends have seen a sandhill crane in a similar place while kayaking recently. Earlier in the season (sorry not to have a date) there was a pair far to the south of the boat launch area. And about a month ago I saw a single crane feeding in a field on the east side of the Bristol/Monkton road, just north of the pond.
I'd love to hear of any more sightings or information about nesting habits in this area.
