It has been seen every day during the past week in pools located in the salt marshes on the west side of Route 1A just south of Odiorne Point State Park in Rye, and was last reported on August 28th. Speculation is that this may be an escaped captive-raised bird. However, there is also the possibility that this is a vagrant wild bird. The duck refuses to comment so we will probably never know its true origin, but it is free for all to admire. A flock of approximately 10,000 TREE SWALLOWS was seen at Cross Beach Road in Seabrook on August 26th.
