Tapaculo diadème

Scytalopus schulenbergi

Petit oiseau gris minuscule avec une queue courte et trapue. Le front et le sourcil gris pâle forment son motif en forme de couronne éponyme, et distinguent l'espèce des tapaculos similaires ; cependant, ce motif gris peut être atténué et difficile à voir chez les femelles. On le trouve dans le sous-bois dense et moussu des forêts naines près de la limite des arbres. Extrêmement timide et beaucoup plus souvent entendu que vu ; écoutez son chant, une série forte et accélérée de notes nasales et plaintives.

Identification

The diademed tapaculo is 10 cm (3.9 in) long; two males weighed 15.2 and 17 g (0.54 and 0.60 oz). The species gets its name from the males' silvery forecrown and supercilium set off by a black "mask" below the supercilium. The male's upper parts are dark gray washed with brown, and it has an orange red rump with dusky bars. It is gray below, lighter to darker front to rear. The flanks and vent, like the rump, are orange red with dusky bars. The female is similar but the "diadem" is smaller and duller and the upper parts' brown wash is darker. The juvenile is a golden brown that is lighter on the underside and has bars and spots throughout.

Taxonomie

The diademed tapaculo has at various times been thought to be closely related to puna tapaculo (Scytalopus simonsi), Vilcabamba tapaculo (S. urubambae), and silvery-fronted tapaculo (S. argentifrons), though the last appears the least likely.

Comportement

The diademed tapaculo forages on and near the ground for insects. It moves quickly while gleaning from moss and vegetation and probing mossy branches.<p>The diademed tapaculo is thought to breed between September and January. The one nest that has been described was a ball of moss and lichens.<p>The diademed tapaculo's song is a trill of varying intensity, pitch, and pace lasting up to 15 seconds [1]. Its scold call is a series of soft notes that lasts about a second [2].
