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.

June 10: MN72 is still spending time throughout the Indian Head, Maryland area, and can be seen following the eastern shoreline of the Potomac River. In June 2018, he flew several hundred miles from this same area -- crossing into Canada -- where he spent the summer months before returning in October 2018. It’s unknown if MN72 will make the same journey this year, but we’ll be watching his tracking data closely during the coming weeks!

May 30: It’s likely that MN72’s GPS transmitter has reported a few inaccurate data points during the past week, resulting in the unrealistically  straight lines of travel that seem to abruptly end. Otherwise, MN72 can be seen completing his usual circuit around Indian Head, Maryland, weaving in and out of the many tidal creeks of the Potomac.

May 13: MN72 can be seen moving throughout a relatively large area during the past week. After following the Potomac River’s eastern shoreline near Indian Head, Maryland, MN72 made a number of out-and-back trips across the water before continuing on to Mason Neck State Park, Virginia. Later in the week, he returned to Maryland, and can be seen most-recently about one mile northeast of Potomac Heights.
