Birds are often credited with keen eyesight but what about their sense of smell?
Among the many birds of the world, some are, without doubt, prodigious smellers.

Gray Catbirds may use their sense of smell to help them on migration.
Diminutive seabirds called storm-petrels (like this European Storm-Petrel) are olfactory savants - they can detect the scent of prey from a distance of 25 kilometers!
