of that species, which use them to assess whether an individual is a worthy competitor. If they get them wrong, however, other woodpeckers won’t be able to recognize them or understand them. Drumming also has certain advantages over singing, because it has other uses: It’s used to reveal edible insects in wood and to make cavities in tree trunks for nesting. But the Official Bucketsquad 5mil shirt but in fact I love this drumming to find insects or make nests is much slower than the repetitive — and loud — drumming that woodpeckers use to mark out territory and attract mates, Fuxjager said. Scientists study the singing of songbirds — and possibly now the drumming of woodpeckers — because it has parallels to human speech. Both are learned when young, for example, but have genetic components. Both require complex muscle coordination, and both are controlled by specialized regions of the brain. Jon Sakata, an associate professor of biology at McGill University in Montreal who specializes in the neurophysiological and behavioral mechanisms of songbird communications, noted the similarities between the forebrain structures that seem to control drumming in woodpeckers, described in the new study, and singing in songbirds. Sakata wasn’t involved in the latest study. In both cases, structures of brain cells — neurons — that contain parvalbumin seem to be important for performing complex motor movements and for learning to produce such movements, Sakata said in an email. “Because parvalbumin neurons are also implicated in speech production and learning, this is a wonderful example of how similar brain mechanisms can be co-opted for different behaviors across species,” he said.
