Tracking MN72

On August 19, 2017, a hatch-year male Bald Eagle was released at Mason Neck State Park in Fairfax County, Virginia. The eagle was rescued in Alexandria in May 2017. Read more about the eagle’s history and rehabilitation here. Prior to release, the eagle was fitted with a GPS transmitter.

At the Center, the eagle was known as #17-1181 – the 1,181st patient admitted to the Center in 2017. Now, the eagle will be known as MN72. “MN” represents Mason Neck, where the eagle was released. The numbers are the last two digits on the transmitter that the eagle is wearing. Each transmitter has a five-digit number written on the side of it in permanent black marker so that the eagle could possibly be identified at a distance.

October 7: Shortly after visiting the Nicolet Bird Sanctuary near Le Trou-d’Henri last week, MN72 flew about three miles southwest and returned to his usual spot at the mouth of the Saint-François River. While MN72’s tracking device transmits data on a relatively consistent basis, there are occasional gaps of up to 24 hours – which may explain the apparent one-way flight path to the southeast.

September 26: For the first time in several months, MN72 seems to be exploring some new areas along the shoreline of Lake Saint-Pierre! He flew about eight miles east, apparently spending several days within the Nicolet Bird Sanctuary – one of 28 migratory bird sanctuaries within the province of Quebec maintained by the Canadian Wildlife Service. His most-recent location looks to be within a privately-owned agricultural area.

September 9: No surprises from MN72 during the past few weeks; he can be seen crossing the Saint-François River several times each day, staying within an area less than two miles in diameter.
