How do birds find their food?
Among most birds, the sense of smell is poorly developed, so they find their food by sight. No other living animals can match the visual acuity of birds.
Male Ruby-throated Hummingbird
The eye of a bird is extremely large by mammalian standards. Though they look relatively small, hidden behind their lids and protective rings of overlapping bone, birds’ eyes are enormous. This is because the image must be big and have sharp details so that they can locate their food while flying. Imagine the extraordinary vision needed by a hawk cruising over a meadow in search of a mouse, a loon in pursuit of its underwater prey, a hummingbird gleaning a minuscule insect near a trumpet vine, and a titmouse searching for a source of black oil sunflower seeds – amazing!
