what is the wingspan of the extinct eagle spizaetus grinnelli

Spizaetus grinnelli, commonly known as Grinnell's eagle, is an extinct species of eagle that lived in North America during the Pleistocene. Estimates of its wingspan suggest it could have been around 2.5 to 2.9 meters (approximately 8.2 to 9.5 feet). This size would have made it one of the largest eagles known. However, exact measurements can vary based on fossil evidence and estimations.
