Without a single exception the Buteos are valuable aids to the agriculturist, as will be shown in detail latert As a class they are rather heavy, deliberate ﬂiers. much given to soaring In circles at a great height. At other times they are prone to select some point of observation on a dead limb in the tree districts. or a knoll in the prairie regions. when they will remain in perfect repose for a long period. seemingly asleep; however. any attempt to approach them by an observer quickly shows that they are alert and watchful.
