These three stamps come from a sheet of six which also include Spider Monkey (Atteles geoffroyi), Margay (Leopardus wiedii) and Mountain Lion (Puma concolor). I had seen this sheet listed on the Nicaragua Post web site early in 2002 but could not find it being advertised in any supplier's list. Consequently, I decided to buy a few sheets directly from the postal authority.

Although the stamps show the date 2000, they were apparently not issued until 27 November 2001.
