"Coua vs. Boa"
by Haley Houghton
Madagascar
is a bird watcher’s dream. We see countless bird species
while checking fossa traps and surveying fragments for lemurs,
so we weren’t surprised when we came across a Red-Capped
Coua in the middle of the trail.
We were surprised, however, by its odd vocalizations.
It was frantically screeching. We stopped briefly to take
of a picture but thought nothing of it and continued down
the trail.
Only
a few steps later I saw the cause of the coua’s distress:
a five-foot long Madagascar Ground Boa, Madagascar’s largest
snake, camouflaged in some leaf litter in the center of
the trail. It was calmly soaking up the sun, a large bulge
visible in its stomach—probably the coua’s mate. Couas are
medium-sized ground dwelling birds that are preyed upon
by numerous species including fossa.
We frequently find piles of coua feathers in the trail—all
that’s left of the easy target after a fossa or a civet
gets hold of one. We left the two opponents as they were
when we found them: the snake digesting its meal and the
coua screeching hysterically. The scene probably went on
like this until the snake sufficiently digested its meal
and retreated into the shade of the forest leaving the widowed
coua alone, pair bonded no more.
