A.) Callimico goeldii Thomas, 1904
1. Common name; local names Goeldi's tamarin; Maquisapita, supaypichico, leoncillo.
2. External characters (Fig. 7)
 |
Coat generally black with coarse and moderately long hair. Crown with short erect hair, rest of the body with longer hair. Upperparts and outside of limbs covered with moderately long, black hair, underparts and inner side of limbs sparsely covered with shorter hair that varies between black and greyish-brown. Tail slightly larger than head+body with long hair varying between black and blackish-brown- Further information is provided by HERSHKOVITZ (1977). |
3. General information
Total length up to 70 cm and weight up to 800 g. Lives preferentially
in low forest, bamboo forest or in secondary forests. Travelling, foraging and
resting preferentially take place in the understory, and frequently they come
down to the ground to capture insects. They sleep in bushes densely covered
with vines and in the scrub growing over fallen tree trunks. Groups contain
3-8, occasionally up to 10 individuals and include an adult pair and their offspring
of varying age. There is no particular birth season, but POOK and POOK (1979)
and MASATAKA (1981a) observed newborn infants in the months of September to
November in northern Bolivia. One infant per birth which is mainly carried and
cared for by the father. The few observations on diet indicate that it consists
mainly of fruits and insects. Among fruits Cecropia sp. and among insects
orthopterans captured in pacales (associations of Guadua sp.,
Gramineae) and on the forest floor seem to be preferred. C. goeldii is
frequently encountered in interspecific association with S. labiatus and S.
fuscicollis weddelli, but occupying different forest strata. Further
information on ecology and behaviour is provided by BUCHANAN-SMITH (199 1 c),
POOK & POOK (1979, 1981, 1982), and MASATAKA (198 1 a, 198 1 b, 1982).
4. Status
Until now the only reports
come from the southeast of Peru in the basins of the rivers Acre and Tahuamanú,
where during the censuses carried out in 1979, 1987 and 1988 several groups
were observed. Individuals of this species were also encountered as pets in
villages on the Rio Mapuya, a tributary of the Rio Urubamba, and in the locality
Atalaya, located on the Rio Tambo. In these settlements, our informants - for
the most part woodcutters - assure us that they have frequently encountered
family groups during their incursions into the forest, which might indicate
its relative abundance in this part of Peruvian Amazonia. Nothing can be said
about its abundance in the northern parts of Amazonia where the species has
not been sighted despite numerous censuses between 1976 and 1987. Consequently,
we consider the species as RARE.
5. Distribution, conservation and protection (Map 4)
Based on information provided by SOINI, HERSHKOVITZ (1977) considers a wide distributional range for C. goeldii, covering the Departments of Loreto, Ucayali and Madre de Dios. However, the collecting localities quoted by HERSHKOVITZ (1977) and the direct observation between the rivers Tahuaman6 and Acre and on the rivers Urubamba and Tambo indicate that its distribution seems to be limited to the southeastern parts of Peru, without definitely ruling out its existence in the north and northeast. C. goeldii is present in the Manú National Park.
