- Observational data : Two transect strips were walked, corresponding to grids of 100 x 100 m mesh. Each transect was walked along a line crossing the grid, observing birds at maximum 50 m on each side of the transect line.
- The NS strip corresponds to a 2.5 km x 200 m strip. The grid consists in two contiguous sub-strips (one north, one south of 100 x 100 m mesh each) stretching E - W between Buanyuantula and the Kulbu pools depression. Three 2.5 km transects lines were walked: one "N" in the middle of the northern strip, one "M", median, at the common border of the two strips, one "S" in the middle of the southern strip.
- Transects B, for "bas-fond" (wetland), has two discrete segments 01B-10B and 16B-25B, and was walked at the higher water limit of the Kulbu pools area.
