5. ACKNOWLEDGEMENTS
This study was funded by a Franzen Fellowship grant from the Amazon
Conservation Association. We thank the staff and promotores at
Los Amigos Biological Station and Los Amigos Conservation Concession,
respectively, for helping to ensure the success of our field work. RBR
would especially like to thank promotore Don Hernan, for his
sense of humor despite numerous language barriers and difficult working
conditions. Special thanks goes to Bioacoustics at the Cornell Lab of
Ornithology for their wonderful technical support and assistance with
acquiring recording equipment, and to Robert Guralnick, for allowing us
to use his personal SD cards. We are further indebted to Larry Chen,
Andrew Dreelin, and Izkak Shafran for their editorial assistance with
the manuscript, and to Adrian Forsyth, without whose support this work
would not have been possible.
