Caratteristiche fisiche da controllare

1. 1

   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Upperparts are typically a mix of buff and orange-brown, finely speckled with grey and black. Underparts are pure white to buff, often with small dark spots, varying geographically. The most striking feature is the pure white, heart-shaped facial disc, bordered by a rufous-brown rim. Flight feathers are barred.

2. 2

   Forma e colore del becco, un segno di campo chiave.

   Small, sharply hooked, pale yellowish-horn colored.

   Colore dell'iride e segni distintivi sugli occhi.

   Small, dark, beady eyes, set within the facial disc.

4. 4

   Colore di zampe e piedi.

   Long, feathered legs with dark grey to black talons.

5. 5

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   Heart-shaped white facial disc, dark eyes, pale plumage, silent flight, and long legs. Its overall pale appearance, especially the white underparts, is a key identifier.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles resemble adults but may have softer, fluffier plumage and less defined facial disc markings. They attain adult plumage after their first molt.

7. 7

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   No significant seasonal plumage changes. Plumage remains consistent year-round, though wear and tear can make it appear duller before molting.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Females are typically slightly larger and heavier than males, and often have more extensive and darker spotting on their underparts and a richer rufous wash on the chest. Males tend to be whiter underneath with fewer spots.

Segni di campo chiave

• Facial Disc. Look for the distinctive pure white, heart-shaped facial disc. This is the most reliable field mark, even in low light.
• Plumage Coloration. Observe the overall pale appearance, especially the white underparts (which may have fine spots). The back is buffy-orange with grey mottling.
• Flight Style. Note its silent, buoyant, and wavering flight, often low over fields. It appears to float rather than flap vigorously.
• Eyes. Its small, dark, beady eyes are set within the white facial disc, contrasting with the yellow eyes of many other owl species.
• Calls. Listen for its characteristic long, eerie, hissing screech ('shreeee'). This is often heard at night and is quite distinct from the hooting of other owls.
• Habitat. Consider the habitat: open country, farmland, and areas with old buildings or barns are prime locations for Barn Owls.
