Identification

Cochevis de Thékla
adult plum. breeding

Thekla's Lark is similar in size to the Crested Lark. Its silhouette is much more compact. It can be distinguished from this species by its shorter beak which has a straight or even slightly convex lower mandible. Both sexes are identical. Its crest is quite full and arranged in a more regular fan shape, which gives it a less pointed shape than the Crested Lark. The facial pattern is somewhat less clear, more diffused. Its upperparts are brownish and its underparts are off-white with well-marked dark streaks on the chest. The clarity and distribution of the chest streaks, the rufous tips of the rectrices and the gray tonality of the wing coverts, allow the experienced observer to easily distinguish it from the Crested Lark. Other criteria can only be ascertained when the bird is in hand, such as the external rectrices edged in cream-rufous contrasting with the neighboring feathers which are dark-brownish or the first primary remex which is longer than the primary covers. Its primary projection is shorter than that of the Crested Lark. Variations in some subspecies may complicate its identification. Juveniles can easily be recognized by their upperparts which are dotted with white-cream. Their crest is less developed.

Voice song and cries

Cochevis de Thékla
adult plum. breeding

Its song, often emitted while in flight, is quite similar to that of the Crested Lark, but softer and more melodious. It is the trisyllabic cry that is distinctive, the tju tit tju. This is monotone in the Crested Lark while it is modulated in Thekla's Lark.

Habitat

Cochevis de Thékla
adult

He likes mostly arid and desert scrubland. He thrives in sparse vegetation, but he can also be found in light woodlands of holm oaks or olive trees, as well as in thickets. Thekla's Lark can also be spotted in sunny spots on higher ground.

Behaviour character trait

Cochevis de Thékla
adult plum. breeding

This species is sedentary and territorial. During the breeding season, Thekla's Lark usually forms loose colonies. In winter it is found in small groups of about ten individuals which can mix with other species such as the Woodlark.

Dietfeeding habits

Cochevis de Thékla
adult

Mixed diet, granivore and insectivore. Insects found under stones and seeds on the ground.

Reproduction nesting

Cochevis de Thékla
adult

Individuals can reproduce from the age of one. The two parents build the nest but the female takes on the greater part of the task as the male is more focused on territory surveillance.

Cochevis de Thékla
adult
The nest is located in an open meadow, simply concealed by a Brachypode rameux or Genêt scorpion plant. It is created with dry blades of grass and sometimes small stones are placed around it to help hold it up. The female lays 3 to 5 eggs in April. The incubation period is approximately 12 days and the young can fly at 15 days. A second laying in June is possible.

Geographic range

Cochevis de Thékla
