The lower lugga (ravine) at PK site, with Euphorbia candelabrum, Acacia gerrardii, A. brevispica, small Oka europaea, Euclea spp., Rhus spp., and other plants, 26 December 1993. Bordering the lugga are Caris- sa-Acacia bushed grassland, in the NW and degraded Combretum-Euclea bushed grassland in the SE with va- rious cisticolas, larks, Black-crowned Tchagra, and Buff-crested Bustards. Fires set by the Pokot and by the ranch staff in the 1990s burned all these habitats with some regularity. The main netting site was in more wooded habitat upstream to the E (right). forest-like thicket in deep "black cotton" soil, which caused us to be mired, or to turn back. OlDoinyo Oirua (OD). A heavily wooded site along a lugga flowing SW from the peak of Ol Doinyo Oirua (really Ol Doinyo Oirirua, meaning "the Dev- il's Mountain," Mol 1996), and situated just below the W edge of the Laikipia Plateau (Fig. 2) at 1970 m, 0°'N, 36°'E, 37 km ENE of Lake Ba- ringo and km NNW of Rumuruti. Thick woods here held many olives, Croton spp., Euclea spp., Rhus sp., Poison-arrow Tree Acokanthera schimperi, and others. Great care was needed here due to the preva- lence of buffalo, elephant and lion that could come upon us suddenly in the relatively dense woods. The many moderate- to large-sized olives provided many cavities for hole-nesting and other woodland birds. Visited regularly from 1987 to 1999, and often chosen when wet because the rocky road readily allowed access. From it one can drive (Fig. 2) up onto the Pla- teau, to the E Ranch border, and W into an old boma on the slope of Kuti Hill. Poromoko (PO). A far S site just under 1 km from the Main Gate, 420 m N of the S border, at 1980 m, 0°'N, 36°20'E, and 6 km NNE of Kinamba (Fig. 2). Dense Olea-Croton woodland (Fig. 16) fringes a very degraded lugga with steep earthen sides, grass with bare ground and bushy thickets beside the woods. We brie
