   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles are mottled brown above with pale spots, and buffy-white below with dusky streaking. They lack the distinct white collar and wing patch of adults, appearing more like a duller, streaked version of the female.

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Breeding males have striking black and white plumage. After breeding, males undergo a post-nuptial molt and become duller, resembling females but often retaining some blackish tones and a larger white wing patch. Females show less dramatic seasonal changes, remaining largely dull brown-grey.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Pronounced sexual dimorphism in breeding plumage. Males are strikingly black and white with a clear white collar, while females are duller brown-grey and white, lacking the prominent collar and having less extensive white on the wings.

Segni di campo chiave

• Male Breeding Plumage. Look for the striking black upperparts and pure white underparts. The key feature is the broad, complete white collar extending around the nape and sides of the neck. Also note the large white patch on the wing.
• Female/Non-breeding Male Plumage. These are duller, with brown-grey upperparts and whitish underparts. Look for a noticeable, though smaller, white wing patch. Females may show a faint pale collar or none at all. Non-breeding males retain some blackish tones and a larger white wing patch than females.
• Song. Listen for the distinctive, slow, and melodious 'tsi-tsi-tsee-tsee-tsee-tsee-tsee-tsee' song, which is less varied and more repetitive than the Pied Flycatcher's. It often has a 'hiccup' quality.
• Behavior. Observe its foraging behavior: perching upright on a branch, then making short, agile sallies to catch insects in mid-air before returning to a perch.
