The New Neotropical Companion

(Elliott) #1
The three Neotropical tapir species are separated by
range and habitat, as discussed in chapter 8. The most
widespread is the Brazilian Tapir (Tapirus terrestris;
plate 16- 35), which can be found east of the Andes from
northern South America throughout Amazonia as far
south as Paraguay. The Baird’s Tapir (T. bairdii) ranges
throughout Central America and northern South
America west of the Andes. The Mountain Tapir (T.
pinchaque) has the most restricted range and is, as the
name implies, essentially confined to higher elevations.
It inhabits the páramos of the Central and Eastern
Cordilleras of the Andes, from Colombia to Ecuador.
Tapirs (and peccaries) are widely hunted, often with
dogs, and thus tend to be wary. Hunting pressure
throughout the range of the various tapir species
has seriously reduced populations. Both Baird’s and
Mountain Tapirs are listed as endangered by CITES
and IUCN. The Brazilian Tapir is listed as locally
endangered by CITES and vulnerable by IUCN.
Tapirs are most active at night, and you will be very
lucky if you manage to see one well. Look for tapirs
along watercourses. They are frequent and excellent
swimmers.

Sloths, Anteaters, and Armadillos
Sloths and anteaters are among the most characteristic
(and “must- see”) animals of Neotropical rain forests.
Along with the armadillos, one species of which ranges
into North America, they compose the magnaorder
Xenarthra (also called Edentata), creatures united by a
number of anatomical characteristics. Anteaters, with

their skulls modified for ingesting ants, are toothless,
but sloths and armadillos have peg- like teeth on the
sides of their mouths (front teeth are lacking).
The term sloth, when applied to a person, has come
to mean sluggish, lethargic, dull, and dim- witted. Real
sloths (families Bradypodidae and Megalonychidae)
are probably all of these things. These traits offer a
tremendous advantage to you, however, because it
means they do stick around once you find them. If you
care to watch a sloth move from one tree to another, a
distance that might take a few seconds for a monkey,
plan to spend about a day or so. Sloths lead slow-
motion lives.
The three- toed sloths (genus Bradypus), the favorites
of Charles Waterton, are the most commonly observed.
Four species range throughout Neotropical forests,
the most common of which is the Brown- throated
Three- toed Sloth (B. variegatus; plates 16- 36– 37).
A three- toed sloth looks somewhat like a deformed
monkey. It has shaggy, tan- colored fur, long forearms
and hind legs (but no tail), and a rounded face with
very appealing eyes. Its sad, vacuous expression gives
the impression that the gleam in its eyes is but the
reflection off the back of its skull. The common name
derives from the three sharp, curved claws on each of
its four feet, which serve as hooks as the animal hangs
upside down from a branch, like an odd mammalian
Christmas tree ornament. The easiest way to find a
three- toed sloth is to scan a cecropia, a favorite resting
and feeding tree for sloths. Sloths frequent trees along
riverbanks and disturbed areas and are much easier to
locate in such habitats than in closed forest.

ate only cecropia leaves, but they are much more diverse in
their vegetarian diets. Photo by Dennis Paulson.
