Lifespan, longevity, and ageing

Maximum longevity: 4 years (wild) Observations: Little is known about the longevity of these animals. Record longevity from banding studies is 4 years (http://www.pwrc.usgs.gov/BBL/homepage/longvrec.htm), but possibly they can live significantly longer.

Justification
Although this species may have a small range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Puerto Rican tanager

The Puerto Rican tanager (Nesospingus speculiferus) is a small passerine bird endemic to the archipelago of Puerto Rico. It is the only member of the Nesospingus genus of the tanager family.

On average the Puerto Rican tanager measures 16 cm and weighs 36 g. These birds are found in groups of about 12 individuals. They are usually found in dense vegetation. This tanager roosts in palm trees or bamboo. The Puerto Rican tanager eats palm fruits, ants and species from the Cecropia genus. Evidence shows that they also eat spiders, lizards and frogs. Its cup-shaped nest is no higher than 9 m in trees. Cream colored eggs speckled with a darker shade of brown. The species breeds from January to August.
