Stummellerche

Bestimmung

The Mediterranean short-toed lark is similar in size and appearance to the greater short-toed lark but is generally a duller-looking bird with a more streaked breast. It grows to a length of from 13 to 14 cm (5.1 to 5.5 in) and the sexes are similar. As with the greater short-toed lark, the colour varies across the broad range and is not a good distinguishing feature. It is dark-streaked greyish-brown above, and white below. It has a pale supercilium, and a short stubby bill.<p>Care must be taken to distinguish this species from the Calandrella larks. This species lacks the dark neck patches of the greater, and has fine streaking across the breast. The bill and head shape also differ, this species having a shorter, less-conical bill and a more-rounded, smaller head. The song is richer, more varied and imitative than that of its relative.

Taxonomie

The Mediterranean short-toed lark was originally described as belonging to the genus Alauda. The genus name Alaudala is a diminutive of Alauda, and the specific rufescens is Latin for "reddish", from rufus "red". Alternate names for the lesser short-toed lark include the common short-toed lark, grey lark, rufous short-toed lark and short-toed lark. Formerly or presently, some authorities considered the Athi short-toed lark, Asian short-toed lark and/or the Somali short-toed lark to be subspecies of the lesser short-toed lark.<p>A molecular phylogenetic study published in 2020 compared the nuclear and mitochondrial DNA from the sand, Asian short-toed, and Mediterranean short-toed larks. The study analysed samples from 130 individuals that represented 16 of the 18 recognised subspecies. The resulting phylogenetic tree indicated that neither the Asian short-toed lark, nor the Mediterranean short-toed lark as currently defined are monophyletic. Most of the subspecies were also found to be non-monophyletic. The authors refrained from proposing a revised taxonomy until additional studies had been completed comparing the vocalizations, sexual behaviour and ecology.<p>Another 2020 study found that the Mediterranean and the Central &amp; West Asian populations of A. rufescens represented two different species, the Mediterranean short-toed lark (A. rufescens) and the Turkestan short-toed lark (A. heinei). A. heinei was lifted to species status by some authorities such as the International Ornithological Congress, and 4 other subspecies originally assigned to rufescens were assigned to it instead. <p>Five subspecies are recognized:<p>4 other subspecies (A. r. heinei, A. r. pseudobaetica, A. r. aharonii, A. r. persica) were transferred to A. heinei when that species was split.

Verbreitung und Lebensraum

The Mediterranean short-toed lark breeds in Spain, north Africa, also including Turkey eastwards across the semi-deserts of central Asia to Mongolia and China. Many populations, including the Spanish and African breeders, are sedentary (non-migratory), but some Asian birds from the north of the breeding range migrate south in winter. This species is a very rare wanderer to northern and western Europe.

Zugverhalten

Verhalten

Die Art lebt in trockenem, offenem Gelände und bevorzugt noch trockenere und kargere Böden als die Kurzzehenlerche. Sie brütet am Boden und legt zwei oder drei Eier. Ihre Nahrung besteht aus Samen und Insekten, wobei Insekten besonders während der Brutzeit wichtig sind.
