Territorial birds, such as penguins, tend to They are herbivores and live in savannas, open woodlands, grasslands, and even desserts (10). k-selected traits: large body size, mature slowly, few offspring, parental care, stable habitats. A National Geographic team has made the first ascent of the remote Mount Michael, looking for a lava lake in the volcanos crater. This rise is a result of genuine growth in some areas, but also stems from more accurate census data, says Julian Fennessy, executive director of the Giraffe Conservation Foundation, based in Namibia. Male giraffes may exceed 5.5 metres (18 feet) in height and female giraffes may reach about 4.5 metres (about 14 feet).
