Ilya is paying social calls along the Susquehanna River, it seems. The National Aquarium confirmed another sighting on Wednesday in Perryville.

Town Commissioner Gary Tennis spotted the marine mammal from Florida, the aquarium reports, and took the pictures you see here.

The aquarium also provided a helpful aerial photo you can see below that shows where the sightings have occurred. I'm not sure if the "unconfirmed" sighting July 20 on the map is the same one aquarium folks had told me about -- of a novice sailor being startled when what she thought was a manatee surfaced next to her boat.  If so, I'd thought that happened Sunday, instead of Monday.

The aquarium says it and the Coast Guard plan to monitor the manatee's movements to ensure its safety.  They ask that boaters in the upper Chesapeake Bay be alert and slow down, especially when in the vicinity of recent sightings.

Any more sightings of manatees (or dolphins or other large marine animals) please call the Maryland Department of Natural Resources Police stranding hotline, 1-800-628-9944.  Also, let us know here at B'more Green, and we'll share any info, pics or video.  But please, don't get too close, for the animals' sake.
