Delalande’s coua( Coua delalandei), also known as the crawler– eating coua or Delalande’s coucal, is an defunct species ofnon-parasitic ditz from Madagascar. It was only known to wisdom as an extant raspberry for a veritably short time in the early 19th century. There’s some disagreement about its area of circumstance Although there were claims that the raspberry was also set up in the area of Fito and Maroantsetra as well as near Toamasina( Tamatave), i.e., the littoral areas of northern Toamasina Province, all samples with good position data are from the coastal islet of Nosy Boraha. As the conversational name implies, land draggers were a favored food item of this species.

Of the 14 samples that live currently, all but two are known to have taken between 1827 and 1834, numerous by the surgeon and naturalist Chevalier Joseph Alphonse Bernier. The Paris type instance was in the collection of the Muséum publicd’Histoire naturelle before that date, and one instance may have been taken as late as 1850. As this species– the alternate– largest coua extant in ultramodern times was veritably spectacular, it was important sought after as a gallery piece. still, it presumably was confined to littoral rainforest on Nosy Boraha, and its niche was largely destroyed by deforestation in the course of the 19th century. preface of black rats may also have contributed to its demise, presumably less by direct predation than by competition for food, but there presumably was a thriving rat population on Nosy Boraha as soon as 1700, considering that the islet was a favorite place for rovers to overhaul. pussycats, which would have feed on the raspberry, were presumably introduced only in the 19th century and make a more likely seeker for an introduced species that had a negative impact on Delalande’s coua.
There are some reports that the locals on the conterminous landmass were still sometimes hunting this raspberry for its ornamental plumage in the 1920s, but these feel in error, these records presumably pertaining to the blue coua. What’s known with certainty is that in 1932, large totalities were offered to well– connected beast dealers in Antananarivo for samples of Delalande’s coua, but they were unfit to land any. The color pattern of the species is unique among couas, which may be a hint that it evolved in fact in the insulation of Nosy Boraha and noway passed anywhere differently. samples from” Tamatave” presumably just indicate their harborage of payload or the position of the beast dealer who carried them.
