Its range is restricted to the Pacific coast of western Panama to the western portion of the Chiriquí Province and of southern Costa Rica, south of the Rio Grande de Terraba, including the Osa Peninsula. It is the subspecies of Central American squirrel monkey seen in Corcovado National Park in Costa Rica. Its type locality is David, Panama, but its range apparently no longer extends that far east.[3] The black-crowned Central American squirrel monkey is orange or reddish-orange in color, with a black cap. It differs from the grey-crowned Central American squirrel monkey, which replaces it in central Costa Rica, in that the limbs and underparts of the black-crowned Central American squirrel monkey are more yellowish. Some authorities also consider the cap on the black-crowned Central American squirrel monkey to be more black than that of the grey-crowned Central American squirrel monkey (C. o. citrinellus), but other authorities regard this as a feature that varies by age rather than by subspecies.[3] Adults reach a length of between {{convert|266|and|291|mm|in|lk=on}}, excluding tail, and a weight between {{convert|600|and|950|g|oz|lk=on}}.[4][5] The tail is longer than the body, and between {{convert|362|and|389|mm|in|abbr=on}} in length.[4] Males have an average body weight of {{convert|829|g|oz|abbr=on}} and females have an average body weight of {{convert|695|g|oz|abbr=on}}.[5] The black-crowned Central American squirrel monkey is arboreal and diurnal. It lives in groups containing several adult males, several adult females and juveniles. It is omnivorous, with a diet that includes insects and insect larvae (especially grasshoppers and caterpillars), spiders, fruit, leaves, bark, flowers and nectar. It also eats small vertebrates, including bats, birds, lizards and frogs. It finds its food foraging through the lower and middle levels of the forest, typically between fifteen and thirty feet high.[6][7] The black-crowned Central American squirrel monkey is one of the few squirrel monkey taxa that has been the subject of a long term study. Primatologist Sue Boinski has made several long term studies of the subspecies.[5] The black-crowned Central American squirrel monkey was assessed by the International Union for Conservation of Nature (IUCN) as Endangered. This was consistent with prior assessments. It is listed as endangered to a small and fragmented range amounting to only about {{convert|4000|km2|sqmi|sp=us}}, and continuing habitat loss.[2] A reforestation project within Panama tries to preserve the vanishing population of the Chiriquí Province.[8] References1. ^{{MSW3 Groves|pages=138–139|id=12100289}} {{Cebidae nav}}{{Taxonbar|from=Q4920094}}2. ^1 {{IUCN2011.2|assessor=Cuarón, A.D.|assessor2=Morales, A.|assessor3=Shedden, A.|assessor4=Rodríguez-Luna, E.|assessor5=de Grammont, P.C.|last-assessor-amp=yes|year=2008|id=19840|title=Saimiri oerstedii oerstedii|version=2011.2|downloaded=19 January 2012}} 3. ^1 {{cite book |author1=Rylands, A. |author2=Groves, C. |author3=Mittenmeier, R. |author4=Cortes-Ortiz, L. |author5=Hines, J. |editor1=Estrada, A. |editor2=Garber, P.A. |editor3=Pavelka, M.S.M. |editor4=Luecke, L. | chapter = Taxonomy and Distributions of Mesoamerican Primates | title = New Perspectives in the Study of Mesoamerican Primates| pages =37–39| isbn = 978-0-387-25854-6 | year = 2006}} 4. ^1 {{cite book|title=Neotropical Rainforest Mammals A Field Guide|edition=Second|author=Emmons, L.|year=1997|isbn=0-226-20721-8|pages=126–127}} 5. ^1 2 {{cite book|title=Primates in Perspective|chapter=The Cebines|author=Jack, K.|editor1=Campbell, C. |editor2=Fuentes, A. |editor3=MacKinnon, K. |editor4=Panger, M. |editor5=Bearder, S. |year=2007|isbn=978-0-19-517133-4|pages=107–120}} 6. ^{{cite book|title=The Natural History of Costa Rican Mammals|author=Wainwright, M.|year=2002|isbn=0-9705678-1-2|pages=131–134}} 7. ^{{cite book|title=The Primate Anthology|chapter=Monkeys with Inflated Sex Appeal|author=Boinski, S.|editor1=Ciochon, R. |editor2=Nisbett, R. |year=1992|isbn=0-13-613845-4|pages=174–179}} 8. ^{{cite web|title=Saimiri Wildlife|url=http://www.saimiri.org/en|accessdate=25 October 2008|deadurl=yes|archiveurl=https://web.archive.org/web/20080507163428/http://www.saimiri.org/en/|archivedate=7 May 2008|df=dmy-all}} 6 : Squirrel monkeys|Mammals of Costa Rica|Mammals of Panama|Primates of North America|Mammals described in 1872|Endangered fauna of North America |
