The Sardinian warbler ( Sylvia sarda ) is a songbird species from the genus of warblers ( Sylvia ). It occurs in the Balearic Islands , Corsica and Sardinia .
features
The Sardinian warbler is similar in size, shape and behavior to the Provence warbler . It differs from this by the gray underside and the missing light throat spot.
The male is uniformly smoky gray, with the exception of the lighter throat. The base of the beak, iris, and legs are red. The female is lighter, more dull but also without a trace of brown. This species has a body length of 13 to 16 centimeters and a wingspan of 25 to 30 centimeters.
Occurrence
The Sardinian warbler breeds on the islands of the Balearic Islands, with the exception of Menorca . It also breeds on Corsica and Sardinia, Capri , Elba and Pantelleria and the Tunisian island of Zembra . Various records with suspected breeding in the Aegean region from the 1990s require further investigation. While the population in the Balearic Islands consists of resident birds, the birds of the eastern subspecies migrate to northern Africa to winter. The Sardinian warbler mostly occurs up to a height of 500 meters, but it can also be found in the mountainous areas of Corsica and Sardinia up to a height of 1800 meters.
It breeds on mountain slopes with low macchia and garrigue , as well as on rocky coasts in the scrub with heather and rock roses , but not in forests.
behavior
The Sardinian warbler usually occurs in pairs or alone. It only forms small groups in autumn and winter. It looks for its food, which consists of insects, spiders and other invertebrates, in the foliage just above the ground.
Reproduction
The Sardinian warbler breeds twice a year. In April to May and a second time in June. The three to four eggs are incubated for 12 to 13 days. The young leave the nest after 12 days.
Internal system
There are described two subtypes, of which the Balearic sometimes as Balearic warbler ( Sylvia balearica of Jordan is guided 1913), which then with Sarda S. a Super species forms. This is justified with differences in size, color, song and migratory behavior as well as studies of the mitochondrial DNA. The rather minor morphological differences do not seem to necessarily justify a species status, migration behavior can hardly be assessed as a taxonomic characteristic and the molecular genetic studies have not been published for several years. More remains to be seen.
