Schuppenbrust-Spottdrossel

Allenia fusca

Eine unscheinbare und unauffällige Art, die typischerweise von der mittleren Baumschicht bis zum Kronendach in Wäldern zu finden ist, wo sie sich hauptsächlich von Früchten ernährt. Diese Art kann von ähnlich geformten und gefärbten Perlenaugen-Spottdrosseln durch ihren kurzen dunklen Schnabel und die gebänderte, nicht gestreifte, Unterseite unterschieden werden. Der Gesang ist eine bewusste Serie von hohen Quietsch- und tieferen Pfeiftönen. Der häufigste Ruf ist ein hoher, dünner Pfiff.

Bestimmung

The scaly-breasted thrasher is approximately 23 cm (9.1 in) long and weighs 53 to 98 g (1.9 to 3.5 oz) with an average weight of 67 g (2.4 oz). With its rather short and slightly decurved bill, this thrasher resembles a thrush. Adults of the nominate subspecies have a dark gray-brown head and upperparts with a reddish tinge on the rump. Their tail is a darker brownish black and its outer feathers have white tips. The folded wing shows a single white bar. Their chin and throat are whitish with brown streaks. The underparts are whitish and the chest and flanks have bold gray-brown markings that give the eponymous scaly appearance.<p>The other subspecies differ mostly in size and the intensity of their upperparts' color. A. f. hypenema is the largest and is paler than the nominate. A. f. schwartzi is mid-sized and has more white on its tail. A. f. vincenti is the smallest and is darker overall than the nominate. A. f. atlantica compared to the nominate is more reddish brown above and has less white in the tail.
