3. Perch design
Perch construction was
simple and inexpensive, using locally
available materials. The main part of
the perch consisted of one 3-m vertical
bamboo pole, approximately 7 cm in
diameter. In addition, two 0.8-m
pieces of bamboo were fitted through
holes cut into the pole, 0.30 m and 0.25
m below the top. These two pieces
were placed at right angles to form
four perpendicular "branches". The
base of each perch was buried 0.5 m
below ground for support. After
placement in the ground, the "branches" were approximately 2.25 and 2.20 m above the ground and
clearly visible (at the start of the project) above the surrounding vegetation. The top "branch" pointed
in a direction parallel to the long axis of the plot, while the other branch was oriented parallel to the
plot's short axis (Fig. 2).
