We recorded the date, time, global positioning system (GPS) co-ordinates, number of individuals seen and perpendicular distance to the line transect (accurately obtained with a measuring tape) for each piping guan detected.
Pooling all records generated a more precise modeling of piping guan detection because the combined AIC values of the separate forest site detection functions were greater than the AIC value for the pooled detection function (Buckland et al.
2] (Table 2) and suggest Carlos Botelho is an important area for Black-fronted Piping Guan conservation.
There are other species for which the status has changed drastically between the writing of the two parts of the book, and there are some, such as the Trinidad Piping Guan (Pipile pipile) that may be more well-known, but the population of which holds on by a thread.
Two Piping Guans Born Through Artificial Insemination
Louis Zoo, a world leader in providing unique and intimate experiences that connect people with animals and their environments, today announced a "first" in documented artificial insemination with the birth of two common piping guans.
