Appearance:

Summer: Red throat (seemingly black at a distance!). Lacks white vertical framing of throat patch and white spotted back of Black-throated Diver. Winter: Quite pale. White face and eye-ring. Just a narrow stripe of dark grey along the back of the neck. In all plumages best identified by posture and silhouette, especially when seen at a distance. Slender neck, head and bill. Flat chest. Usually shows no white flank patch. Bill usually held uptilted.

Sound:

In flight; nasal, dry, gooselike series of rhythmic cackling "ko-ko-ko". Most vocal when courting and breeding. A meowing drawn-out sound starting with a register break, then falling in pitch. Display call a far reaching rolling cyclic cooing, given in long sequences.

Appearance:

A medium sized, brown and long-winged owl, with long ear-tufts and deep orange eyes. Only half the size of Eagle Owl. Differs from the more similar Short-eared Owl by darker (orange) eyes, longer ear-tufts and heavily streaked lower belly. In flight, note paler wing-tips (only finely barred, not tipped black).

Sound:

Song a series of very deep, monotonous "hooooo"s, quite widely spaced. Uttered about once every 2-3 seconds. Sometimes rises in pitch, but with each "hoo" being constant. Rich repertoire of calls. Other sounds include; a nasal "eeeeeaaa" reminiscent of Collared Dove, nasal mewing and bill clicking.
