Camarhynchus pauper
Pinzón de Árbol Mediano, Pinzón arboreo mediano, Medium Tree Finch
Threats Threats are similar to all other finches, particularly very low nesting success due to the introduced parasitic fly Philornis downsi: the flies lay the eggs in the nest and larvae suck the blood of the nestlings, causing anaemia, lesions and consequently nestling mortality. There is predation by the introduced black rat. The impact of diseases is unknown.

Species
pauper
Taxon category: Accepted
Taxon origin: Endemic
Reproduction mode: Exclusively sexual
Reproductive biology: Males display in front of a dome shape nest high up in the canopy. Once chosen, the pair either use this nest or build a new one. Only females incubate (two to three eggs), both feed the chicks. Fledglings stay for up to 6 weeks with a parent, either with the male while the female starts a new clutch, or, one with the female and the other with the male.
