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 5: MN72 spent the holiday season in a familiar area this year, flying throughout Spotsylvania County, Virginia in a similar pattern compared to his previous updates. A closer look into the tracking data reveals that on New Year’s Eve at 11:08 p.m., MN72 was located in a heavily forested area about four miles west of the community of Chancellor. On January 4, he began flying north and reached his current location on the Potomac River by January 5 after covering approximately 40 miles.

December 22: Compared to his previous update, MN72 appears to be following a similar pattern of movements and has extended the range of areas he’s visited. Starting near Glenora, VA, MN72 began traveling northeast and crossed the Potomac River into Maryland on December 13. Continuing in a clockwise direction, he flew north for about 12 miles until he reached Piscataway Park – a recreational area managed by the National Park Service. On December 15, he began to fly southward and crossed the Potomac once more into Virginia. Five days later, he had returned to the Gelnora area and seems to be spending time in a rural undeveloped area.

December 10: During the past few weeks, Bald Eagle MN72 has been moving throughout some new areas in comparison to his recent updates. He can be seen flying overhead Indian Head, Maryland as anticipated, but was also tracked making flights across the two-mile-wide Potomac River on several occasions. On November 27, he began flying southward, arriving in King George, Virginia, that same day. A cluster of data points near what appears to be a waste-management facility can be observed during his movements to the southwest, ending at his most recent location near Lake Anna State Park – the site where a former Bald Eagle patient was released back into the wild in September 2021.
