Autumn vagrant in Suffolk, UK
观察细节
Continuing 1cy showing well, albeit distantly, on fence line running NE from road. Similar in size and structure to Red-backed Shrike, but appeared slightly bigger headed and longer tailed. Upperparts rather plain, warmish mid-brown, richest and toned more rufous on crown and scapulars. Flight feathers darker brown, with prominent pale edges to secondaries and tertials forming conspicuous pale wing panel. Primary projection not significant, enhancing long-tailed look. Tail quite rufous, with short outermost feather just about visible in one image. Underparts creamy off-white with prominent greyish barring on sides of throat, breast (almost meeting in centre) and flanks down to edges of rump. Supercilium only distinct behind eye, appearing as creamy off-white patch with greyish barring at rear, above neat dark blackish-brown ear-covert patch running back from dark eye. Indistinct tiny pale spot in front of eye. Bill appeared pale in strong sunlight, perhaps with darker tip; legs grey. Fed actively, disappearing frequently into bracken before returning to fence line, and seemed to attract interest from European Stonechats and, briefly, a Dartford Warbler, all of which perched close to it on fence and stayed near to shrike even when latter moved - not sure if tentative mobbing or possibly some kind of feeding association (as Dartfords sometimes exhibit with stonechats).
