Southern Yellow Bat
We first found this beautiful species roosting in our large bamboo plant in early June 2014 and have since caught it in our nets under special licence from Parques y Reservas. Although the Ibera marshes are just inside of its range, it defines the southern boundary and it has not previously been reported here. It is insectivorous and belongs to the Vespertillionidae family and is a medium sized, uncommon bat.
It is covered with thick pale yellow fur back and front and its tail is enclosed in a membrane which it uses for scooping up prey. The ears are medium sized and close to the side of the head with a relatively large rounded tragus. It has narrow high aspect ratio wings.
It roosts in trees, especially Palms where it is hidden in the dead yellowish fronds and we also found it in a large bamboo plant. As with most bats the female is larger than the male.
