Caratteristiche fisiche da controllare

1. 1

   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Adult males in breeding plumage typically have a black crown, nape, and throat, contrasting with a white face and underparts. The back is grey, and the wings are black with prominent white wing-bars. The long tail is black with white outer tail feathers. Females are similar but often have a duller black on the head and throat, sometimes appearing more greyish-black. Non-breeding adults have less extensive black on the head and throat, often with a white throat and a black crescent on the breast.

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   Long, constantly wagging tail; striking black, white, and grey plumage; undulating flight pattern; often seen running on the ground.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles are generally duller and browner than adults. They have a greyish-brown crown and back, a buffy-white face, and a dirty white throat and underparts. The black bib is absent or very faint, replaced by a greyish wash on the breast. The wing bars are buffy rather than pure white.

7. 7

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Adults undergo a partial pre-breeding moult in late winter/early spring, acquiring their crisp black and white breeding plumage. A complete post-breeding moult occurs in late summer/autumn, leading to the duller non-breeding plumage with reduced black on the head and throat.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Subtle. Males in breeding plumage have more extensive and intense black on the crown, nape, and throat. Females may have a duller black or more greyish-black, and sometimes a less defined black bib. In non-breeding plumage, differences are minimal.

Segni di campo chiave

• Plumage Pattern. Look for the distinct black, white, and grey pattern. White face, black cap and bib (in adults), grey back, and black wings with white wing-bars are key. Juveniles are browner and duller.
• Tail Wagging. The most characteristic behavior is the constant, rhythmic up-and-down wagging of its long tail, even when standing still. This is a strong field mark.
• Gait and Foraging. Observe its distinctive running and stopping gait on the ground, often in open areas. It will dart forward, pause, and then pick up insects.
• Call. Listen for its sharp, disyllabic 'chi-tsip' or 'chissick' call, often given in flight. This is a reliable auditory cue.
• Habitat. Look in open, often disturbed areas near water or human habitation, such as car parks, riverbanks, fields, and urban parks.
