The lesser whitethroat (Curruca curruca) is a common and widespread

Palearctic. This small passerine bird is strongly migratory, wintering in Africa just south of the Sahara, Arabia
and India.

Unlike many sylviid warblers, the sexes are almost identical. This is a small species with a grey back, whitish underparts, a grey head with a darker "bandit mask" through the eyes and a white throat. It is slightly smaller than the common whitethroat, and lacks the chestnut wings and uniform head-face colour of that species. The lesser whitethroat's song is a fast and rattling sequence of tet or che calls, quite different from the common whitethroat's scolding song.

Like most "warblers", it is

eggs

Taxonomy

The lesser whitethroat was

locality as Europe but this was restricted to Sweden by Ernst Hartert in 1909.[4][5] This species is now placed in the genus Curruca that was introduced by the German naturalist Johann Matthäus Bechstein in 1802.[6][7]

This species has been commonly assumed to be closely related to the

taxa are not particularly close relatives.[citation needed
]

Rather, the lesser whitethroat and its closest relatives

Arabian
region (which also occurred throughout the Ice Ages).

The lesser whitethroat complex has been split up into the present species, Hume's whitethroat, and the small whitethroat from which the Margelanic whitethroat may also be specifically distinct. In this

superspecies, the lesser whitethroat seems to form the basal European lineage. Six subspecies are nowadays unequivocally accepted[7]
for the lesser whitethroat, and they intergrade throughout Central Europe and Asia:

Two more taxa occur in the intergradation zone with the small whitethroat, stretching from the northern

phylogeny of these is not well-researched, and they might eventually turn out to belong to either species or be stereotyped hybrids
:

  • Curruca curruca/minula halimodendri
  • Curruca curruca/minula telengitica

Similarly, Curruca curruca caucasica described by

Banjkovski in 1910 is intermediate between the lesser and Hume's whitethroats.[10]

A bird which wintered at

mtDNA sequences from all known taxa in the complex, although it most closely resembled halimodendri in the field. As mtDNA is inherited from the mother only, were this bird a hybrid this should have been recognisable.[11]
