Basho hills (Figure 2) and, for C. nictitans, <strong>the</strong> Obonyi 1<br />
hills (Table 3). In <strong>the</strong> Matene hills, only C. nictitans was<br />
heard along <strong>the</strong> transects, although C. erythrotis was<br />
heard dur<strong>in</strong>g a ‘site selection’ walk.C. erythrotis was not<br />
seen at all along transects <strong>in</strong> <strong>the</strong> highlands and rarely seen<br />
or heard <strong>in</strong> <strong>the</strong> lowland areas (a total <strong>of</strong> 10 sight<strong>in</strong>gs and<br />
7 vocalization records <strong>in</strong> 12 months). Cercopi<strong>the</strong>cus<br />
preussi was heard just 8 times on transect walks <strong>in</strong> 12<br />
months, twice <strong>in</strong> <strong>the</strong> hills <strong>of</strong> <strong>the</strong> Basho area.<br />

3.4 Tracks, dung, and o<strong>the</strong>r signs<br />

Track data were recorded at <strong>the</strong> hill sites dur<strong>in</strong>g <strong>the</strong> dry<br />
season when leaf litter covered <strong>the</strong> ground, mak<strong>in</strong>g it<br />
difficult to see tracks. In addition, <strong>the</strong> hill strata were<br />
mostly rocky, and tracks did not show up well. In <strong>the</strong><br />
lowland sites, frequent heavy ra<strong>in</strong>storms dur<strong>in</strong>g <strong>the</strong> wet<br />
season washed away tracks. Because <strong>of</strong> <strong>the</strong>se conditions,<br />
<strong>the</strong> results <strong>in</strong> this section are somewhat subjective.<br />
Encounter rates for tracks were low throughout. The<br />
different animal tracks recorded along <strong>the</strong> transects were<br />
mostly made by ungulates, and most <strong>of</strong> those were<br />
