The first Ruby-throated Hummingbird banded for the Michigan HummerNet project was a hatch-year female banded at the Rouge River Bird Observatory (RRBO) on August 7, 2001. 

Band number R(4000)-xx101 was placed on her right leg.  Her wing measured 44.87 millimeters, her bill measured 17.79 mm, and she weighed 2.9 grams with no fat.  She was released at 10:40 a.m. E.S.T.
