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.
March 17: Bald Eagle MN72 has continued to fly some impressive distances during the past month. In his previous update, tracking data showed him moving into northern Virginia from Maryland somewhat unexpectedly. Examining his flight patterns during the past few weeks shows that he's repeated this trip several times -- flying distances of up to 20-30 miles in-between the times when his GPS unit communicates with the online servers.
January 28: MN72 has been showing some unexpected movements during the past few weeks! After he flew southwest from Indian Head, Maryland and crossed the Potomac River into Virginia, he continued moving inland for about 30 miles. When he reached central Spotsylvania County, he abruptly turned around and flew back to his most recently known position near the King George Landfill in Johnsons Corner, Virginia.
January 6: MN72 spent the past few weeks flying throughout his expected ranges, moving across the Potomac River a number of times. According to his tracking data, MN72 spent New Year's Eve in a rural area about three and a half miles west of the Potomac within Charles County, Maryland. The square icon seen on the satellite imagery shows where MN72 was on December 31 at 11:06 p.m.
