Very occasionally eagles, perhaps following territorial dispute or miscalculation over prey, end up in the water. With wings spread across the surface they are quite buoyant, but must row, overarm, to shore, which is an exhausting process. They emerge soaked and bedraggled and must dry out before they can take to the air again. Senses ‘Eagle-eyed’ – keen of eyesight, vigilant or, by extension, perceptive’. Eagles are much admired for their powers of sight and vision is their primary sense. Their visual acuity, that is, the ability to resolve spatial detail, is variously claimed to be two to eight times that of humans.

The main feature that nest sites share is a prominent position and, where possible, shelter from the prevailing winds and hot afternoon sun, and access to the morning sun. Energetics are also a consideration in the siting of nests because adults must carry heavy prey to the nest and active, flapping flight is energetically costly for the eagle. So, for example, although typically nest trees are located about mid-slope, where the slope is particularly high but hunting land is below, the eagles may nest lower on the slope.
