AmphibiaWeb - Hyla sarda


(Translations may not be accurate.)

Hyla sarda (De Betta, 1853)
Sardinian Tree Frog, Tyrrhenian Tree Frog, Sardischer laubfrosch, Tyrrhenischer laubfrosch, Rainette Sarde, Raganella sarda, Raganella tirrenica, Sardijnse boomkikker
Subgenus: Hyla
family: Hylidae
subfamily: Hylinae
genus: Hyla
Taxonomic Notes: Duellman et al. (Zootaxa 2016) treated two major clades as genera; AmphibiaWeb treats these two clades as subgenera(Hyla in the Old World; Dryophytes in the New World and East Asia), thus stabilizing traditional taxonomy.

Small tree frog, usually 38-40mm snout-vent length. Dark stripe on the flanks, starting at the nostril, through the eye and breaking up into spots halfway along the flanks. The head is broader than long, and the snout is shorter than in Hyla arborea. Adhesive discs on all digits. The skin is more granular than in Hyla arborea and Hyla meridionalis. Color and pattern variable and under physiological control. Color can be greenish, olive or gray, usually with dark green or gray spots. Dark bands are usually visible on the outside of the hind legs. Venter is whitish. The pupils are horizontal. The tympanum is clearly visible. (Noellert and Noellert 1992)

Hyla sarda is present on the following Mediterranean islands: Corsica, Elba, Cavallo, Sardinia, Maddalena, Caprera and San Pietro. Possibly also occurs on Spargi, San Stefano, Guardinelli, and Santa Maria. Hyla sarda lives in the vicinity of pools, ponds, creeks and streams, usually in woody areas. In inhabited areas they can be found in gardens and in wall cracks, as long as there is water nearby. For reproduction sites Hyla sarda prefers natural springs and cisterns. Hyla sarda is relatively heat tolerant and is tolerant of higher saline concentrations of its breeding waters than Hyla arborea and Hyla meridionalis.

Life History, Abundance, Activity, and Special Behaviors
The life history of Hyla sarda is relatively unknown. This can be attributed to its isolated island distribution, and to the fact that this tree frog was considered a subspecies of Hyla arborea until 1983. The species is active during twilight and night. The frogs spend the hot hours of the day in shady retreats. The nightly wanderings can be as far as 500m. The call is similar to that of Hyla arborea.

Trends and Threats
A potential danger to this species comes from its isolated island distribution. It has been studied relatively little and therefore there is insufficient data to make any statements about the status of Hyla sarda.

Relation to Humans
Inhabits gardens and retreats into cracks in walls.
