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.

January 17: It’s been another week of patrolling the tidal creeks and rivers near Indian Head, MD for Bald Eagle MN72. He’s continued to fly in a roughly circular direction throughout the six mile-wide area, making plenty of stops over agricultural and rural areas. His most recent position appears to be on the edge of a small pond near a private residence.

January 9: MN72 has spent that past month flying throughout the Indian Head, Maryland area, and seems to be making regular trips across the roughly one mile-wide Potomac River. Apart from Indian Head, MN72 spent the most amount of time flying through King George County, Virginia. 

December 9: As expected, MN72 has been spending time near the Indian Head, Maryland area along the Potomac River. However, a handful of data points from MN72’s tracking device – visible near Charlottesville, Virginia – are very likely inaccurate based on the unnaturally linear path of travel. It’s not exactly clear why these errors occur, but it appears MN72’s tracking unit quickly resumed functioning as normal soon after.
