Aegolius funereus
The Tengmalm's Owl is a rare and irregular winter visitor to Britain, typically seen in the northern and eastern parts of the country, often in coniferous woodlands. It is most likely to be spotted during periods of harsh weather on the continent, which can drive individuals to cross the North Sea.
Use these features to identify Tengmalm’s Owl in the field.
The Tengmalm's Owl can be identified by its distinctive white spots on the forehead, a rounded head, and a lack of ear tufts, giving it a unique appearance. Its yellow eyes and black-edged white facial disk are also key features.
The Tengmalm's Owl is smaller than a Tawny Owl, but larger than a Little Owl, with a compact and stocky build.
The male Tengmalm's Owl has a grey-brown back and wings, with a reddish-brown tint to the feathers, and a white underside with dark brown streaks, showing little seasonal variation.
The female's plumage is similar to the male's, with a slightly more reddish-brown hue to the upperparts and a paler underside.
The Tengmalm's Owl's call is a series of low, whistled notes, often described as a haunting, mournful sound, typically heard at dawn and dusk.
The Tengmalm's Owl is a nocturnal hunter, using its acute hearing to catch small mammals, birds, and insects, and is known for its silent, wingbeat-free flight when approaching prey.
The Tengmalm's Owl can be confused with the Long-eared Owl, but can be distinguished by its lack of ear tufts, more rounded head, and distinctive white spots on the forehead, as well as its smaller size and more compact build.
