Rodrigues day gecko (Phelsuma edwardnewtoni) is a now extinct diurnal species of geckos. It lived on the island of Rodrigues and typically inhabited forests and dwelt in trees. The Rodrigues day gecko fed on insects and nectar.
Description
This day gecko is now extinct. It was described also as P. newtonii, yet this name was also used as a synonym for Phelsuma gigas. P. edwardnewtoni belonged to the largest day geckos. It reached a total length of about 23 cm. Earlier investigators describe the animal as being quite common. However, this species has not been sighted since 1917, in spite of thorough searches in the 1960s and 1970s on Rodrigues and all offshore islets. Today, only 5 preserved specimens remain, three of which are in The Natural History Museum in London, the two others being in the Paris Natural History Museum. These specimens have been preserved in alcohol and show a thick-bodied, robust Phelsuma. The body colour has been described as bright green with bright blue spots on the back. The underside of the tail was whitish yellow. The chin had a deep yellow colour.
Behaviour and ecology
This species inhabited Rodrigues Island and its surrounding islets. P. edwardnewtoni has been observed on coconut trees and other palms. Their habitat has been largely destroyed by humans and introduced animals such as cats and rats, which may have been the main cause of their extinction.
These day geckos fed on various insects and other invertebrates. They also liked to lick soft, sweet fruit, pollen and nectar.
P. edwardnewtoni was documented as being unafraid of humans. It was quite tame and would even eat fruit from one's hand. Leguat described the behaviour as follows:
The Palmtrees and Plantanes are always loaden with Lizards about a foot long, the Beauty of which is very Extraordinairy; some of them are blue, some black, some green, some red, some grey, and the colour of each the most lively and bright of any of its kind. Their common Food is the Fruit of the Palm-Trees. They are not mischievous, and so Tame, that they often come and eat the Melons on our Tables, and in our Presence, and even in our Hands; they serve for Prey to some Birds, specially the Bitterns. When we beat 'em down from the Trees with a Pole, these Birds wou'd come and devour them before us, tho' we did our utmost to hinder them; and when we offered to oppose them, they came on still after their Prey, and still followed us when we endeavoured to defend them.[1]
