Small Tree Finch

The small tree finch (Camarhynchus parvulus) is a bird species belonging to the Darwin's finch group within the tanager family Thraupidae. It has a grasping beak with curved culmens. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. During the non-breeding season it is known to form large groups with small ground-finches. It is an endemic species to the Galapagos islands and its conservation status has been listed as "Least Concern". However, bird counts which have been conducted since 1997 have shown a continuous decline in small tree-finch populations in the Scalesia and agricultural zones of Santa Cruz, where the small tree-finch is most abundant. Small tree-finch counts have remained stable in the transition zone (also quite abundant here) and in the less popular dry and fern zones on Santa Cruz island. This species is in particularly impacted by the larvae of the parasitic avian vampire fly (Philornis downsi). == Distribution == The small tree finch is found on all the main islands except Española, Genovesa, Marchena, Darwin, and Wolf. It was also absent in the most recent census (2017–2018) on Rábida, Pinta, and Santa Fé islands. == Mating == Darwin's tree finches build…
