Cornell University’s Laboratory of Ornithology has released recordings from Arkansas of possible calls and drumming by one or more ivory-billed woodpeckers.
The release will fuel a new round in the debate over whether the bird, long considered extinct, still makes its home in the state’s Big Woods area. Last April, a consortium including the Cornell lab announced sightings of at least one bird (SN: 5/7/05, p. 291: Alive and Knocking: Glimpses of an ivory-billed legend), but some other scientists challenged the evidence.
