The dusky-billed parrotlet (Forpus modestus), also known as Sclater's parrotlet, is a small species of parrot in the family Psittacidae. It is the nominate species (F. m. modestus).
There is one subspecies: Forpus modestus sclateri.

(Forpus modestus modestus) |Typically {{Convert|12-12.5|cm|in|abbr=}} long and weigh {{Convert|30-35|g|oz|abbr=}}. Body is mostly dark green to yellow-green; eyes are dark brown and feet are dark gray. Upper mandible is dark gray while lower is light peach. Dusky-billed parrotlets are sexually dimorphic: males have blue-purple feathers on their lower back, rump, primary and secondary coverts, primary and secondary feathers, and underwing coverts. Females have no blue markings and a brighter yellow-green forehead, forecrown, and cheeks. Like all parrots, dusky-billed parrotlets exhibit zygodactyly: two toes face forward and two toes face backward.{{Cite web|url=https://www.parrots.org/encyclopedia/dusky-billed-parrotlet/|title=Dusky-billed Parrotlet (Forpus modestus) {{!}} Parrot Encyclopedia|website=www.parrots.org|access-date=2019-03-18}} Juveniles look like adults, with duller colorations.

Distribution and habitat
The dusky-billed parrotlet is found in the Amazon Rainforest in South America, where it is locally fairly common; it also occurs in the Andes and the Amazonian foothills, the Amazon River outlet, and Marajo Island.
Dusky-billed parrotlets prefer lowland tropical rainforest edges and clearings, riparian zones, secondary habitats, and savanna. They seem to favor seasonally-flooding forests.{{Cite web|url=https://neotropical.birds.cornell.edu/Species-Account/nb/species/dubpar1/overview|title=Dusky-billed Parrotlet - Introduction {{!}} Neotropical Birds Online|website=neotropical.birds.cornell.edu|access-date=2019-03-18}} They are not found at altitudes higher than {{Convert|1000|m|ft|abbr=}} above sea level.
Conservation
According to the IUCN Red List, dusky-billed parrotlets are a species of Least Concern. Their population size is unknown, but is believed to be stable.
= Threats =
Unlike many members of the genus Forpus, they are not captured for the parrot trade, and they are relatively unaffected by deforestation. There are many protected areas throughout their range.

= Reproduction =
File:PsittaculaSclateriKeulemans.jpg, 1891|alt=]]Dusky-billed parrotlets typically breed during July. Clutch size is unknown, but eggs are small, white, and roughly spherical. They nest in tree cavities or similar structures.
= Diet =
Dusky-billed parrotlets' diet consists of approximately 10% seeds, buds, and blossoms and 90% berries and fruits,.{{Cite journal|last1=Benavidez|first1=A.|last2=Palacio|first2=F.X.|last3=Rivera|first3=L.O.|last4=Echevarria|first4=A.L.|last5=Politi|first5=N.|date=15 July 2018|title=Diet of Neotropical parrots is independent of phylogeny but correlates with body size and geographical range|journal=Ibis|volume=160|issue=4|pages=742–754|doi=10.1111/ibi.12630|doi-access=free}} Grass is occasionally eaten as well. Dusky-billed parrotlets have also been observed to eat clay as a primary source of minerals.
Taxonomy
The dusky-billed parrotlet was previously described by the name Forpus sclateri by Jean Cabanis in 1849 but later reassigned to the genus Psittacula as Psittacula modesta by George Robert Gray in 1859. However, because the name modesta was assigned to at least two closely related birds of the genus Psittacula, the dusky-billed parrotlet was reverted to F. sclateri. As of 2006, the binomial name for the dusky-billed parrotlet is Forpus modestus, with F. m. sclateri as a subspecies.{{Cite journal|last1=Pacheco|first1=J.F.|last2=Whitney|first2=B.M.|date=27 January 2006|title=Mandatory changes to the scientific names of three Neotropical birds|url=https://www.researchgate.net/publication/264850259|journal=Bulletin of the British Ornithologists' Club|volume=126|pages=242|via=BioStor}}
It has been suggested that the dusky-billed parrotlet is basal to all other species of the genus Forpus based on diversification and speciation rates and patterns.{{Cite journal|last1=Smith|first1=B.T.|last2=Ribas|first2=C.C.|last3=Whitney|first3=B.M.|last4=Hernández-Baños|first4=B.E.|last5=Klicka|first5=J.|date=28 November 2012|title=Identifying biases at different spatial and temporal scales of diversification: a case study in the Neotropical parrotlet genus Forpus|journal=Molecular Ecology|volume=22|issue=2|pages=483–494|doi=10.1111/mec.12118|pmid=23190339|s2cid=2073545}}
Aviculture
The dusky-billed parrotlet is not commonly available in aviculture. It is not commercially available in the U.S. and is very uncommon in Europe.
