The putative Ivory‐billed Woodpecker double‐knock was recorded in our study area by an AudioMoth ARU on February 18, 2019. The Pale‐billed Woodpecker drum was recorded by P. Driver in Belize in March 2019 (Xeno Canto XC522869); the Powerful Woodpecker drum (Macaulay Library ML90035181) was recorded by D. Uribe‐Restrepo in Colombia in August 2016; the Robust Woodpecker drum (Xeno Canto XC48884) was recorded by B. Lopez‐Lanus in Argentina, date unknown. The audio recording of the putative Ivory‐billed Woodpecker double‐knock can be heard in Appendix 2.
