I contribute bird sightings to the global citizen scientist project eBird and submit photos to the online wildlife media archive Macaulay Library. I also use the open access bird sound archive xeno-canto and occasionally contribute to iNaturalist.
The community-based online reference work Neotropical Birds has been incorporated into Birds of the World run by the Cornell Lab of Ornithology. In 2013 I wrote species accounts for Yellow-thighed Finch (Pselliophorus tibialis), Yellow-green Finch (Pselliophorus luteoviridis) and Large-footed Finch (Pezopetes capitalis).
Some of my photos on eBird have been used for the species accounts of Pincoya Storm-Petrel (Oceanites pincoyae), Green-backed Firecrown (Sephanoides sephaniodes) and Olive Finch (Arremon castaneiceps).
