Caratteristiche fisiche da controllare

1. 1

   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Males in breeding plumage have a pale grey crown and nape, a black mask extending from the bill through the eye, white supercilium, and buffy-white underparts. The back is grey, and wings are blackish. The most striking feature is the white rump and basal half of the tail, with a black inverted 'T' pattern at the tail tip. Females are duller, with brownish-grey upperparts, a less defined brownish mask, and buffier underparts. Non-breeding males resemble females but retain some grey on the head. Juveniles are mottled brownish with pale spots.

Segni di campo chiave

• Rump and Tail Pattern. Look for the bright white rump and the distinctive inverted black 'T' pattern on the tail. This is the most reliable field mark in all plumages.
• Male Breeding Plumage. Identify the grey crown and nape, black mask through the eye, white supercilium, and buffy-white underparts. The grey back contrasts with blackish wings.
• Female/Non-breeding Plumage. Note the duller, brownish-grey upperparts and buffier underparts. The facial mask is less defined and brownish. The white rump and tail pattern remain key.
• Behavior. Observe its upright posture, frequent tail flicking, and habit of perching on prominent rocks or mounds in open habitats.
• Call. Listen for the sharp 'chack' call, which is often given when disturbed or as an alarm.
