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.

November 22: MN72 appears to have settled into the Indian Head, Maryland area during the past few weeks. He can be seen flying over both agricultural and suburban areas, taking different routes while exploring the five mile-wide area. MN72 also paid a brief visit to Mason Neck, Virginia – the site of his original release in May of 2017!

October 31: After spending four months along the shores of the Saint-François River in Quebec, MN72 left the area and began the long journey south! On October 10, he crossed the border and re-entered the US into Vermont. Eleven days later, he had covered about 240 miles and was tracked at the New York-Pennsylvania state line. By October 28, MN72 was flying through central Maryland, and as of this update he’s less than three miles from Indian Head, Maryland – the exact location he left in June! In total, MN72 has covered more than 550 miles in just a few short weeks. It’s unknown if he’ll remain near the Indian Head area throughout the winter, but we’ll keep a close eye on his tracking data to find out!

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.
