Rufous-headed Woodpecker
The Rufous is classified as a bamboo specialist. There are 19 other bird
species classified as bamboo specialists, with another 10 or so species in
Tambopata.
In July 1998 while on a Gone Wild Productions expedition into the Tambopata
region of Peru, we found the first ever-active nest site of the species, Celeus
spectabilis.
Never
before had an active Rufous nest been filmed and documented. The voice had never
been described. It's food unknown and the breeding season was assumed to be
June-November.
Andrew
W. Kratter found the first nest back in 1992, but only recently published a
paper on it in 1998. In his paper he describes the nest being found in a dead
tree, similar to the tree we found, and with the soft pith. The only observation
Katter made of the behavior was that two adult birds flew in and out of a hole
several times. He did not find a nest with young.
Rufous-headed
woodpeckers are very hard to find. Not only are they rare but each pair have
a large territory and they hardly ever sing. Except now we know they sing a
lot during the breeding season when raising young.
What
they feed on is still a bit of a mystery. We have seen them feeding on dead
bamboo stems. It should be said at this point that bamboo stems do house a very
unique community of invertebrates. The Rufous spends more time foraging on dead
stems than live ones. When feeding on the live stems it just seems to drill
holes and then leaves, rather than wait for prey to emerge and then eat it.
The Rufous returns to the holes that it had made in the stems some 3-4 days
later to find out what has colonized in the holes. If this is true then this
represents some remarkable feeding behavior, since the birds would appear to
be actively "farming" invertebrates from live bamboo stems. This behavior
does warrant some further investigation.
As
of 1998 the only collected specimens of this species are housed in the United
States at the Louisiana State Museum in Baton Rogue.
