This experience provided us with descriptions and measurements of the nests, eggs, and other aspects of reproduction of the Speckled Chachalaca and Rusty-margined Guan.
On 20 August 2011, we captured an immature guan (mass = 514.
Nests of cracids are built at variable heights in forest vegetation and in different support plants (del Hoyo 1994), as we found guan nests ranging from 0.
Reproductive biology and vocalizations of the Horned Guan Oreophasis derbianus in Mexico.
Density and natural history of the Sickle-winged Guan (Chamaepetes goudotii) in the Central Andes, Colombia.
Louis Zoo intends to establish a reservoir of frozen guan
semen, enabling us to teach these artificial insemination and freezing techniques to zoos in Central or South American countries which have access to endangered Cracid species.
Both the White-winged Guan
and the Homed Guan
are represented by plates showing the development from downy chick to adult.
Observations by German Corredor of captive Sickle-winged Guans in the Cali Zoological Park suggested that males and females can be differentiated by morphological characters.
The density estimate for Sickle-winged Guans in the study area was 13.
Sickle-winged Guans traveled mainly in the middle vertical stratum of the forest (8.
We observed Sickle-winged Guans consuming a variety of foods including fruits, flowers, leaves, and invertebrates (Table 2).
The Sickle-winged Guans on our study area occurred at higher densities compared to other cracids (Terborgh et al.
We observed Sickle-winged Guans in all forest types available within our study site and one of the ash plantations.
Sickle-winged Guans were detected on the forest floor but most of these records corresponded to individuals capturing invertebrates while following army ants.
