  1. Taxonomic & data-quality challenges of large-scale citizen science:Examples from Marshall J. Iliff, eBird Project Leader

  2. Growth in eBird Observations & Checklists Observations Checklists

  3. In 2009, volunteers contributed more than 780,000 hours collecting bird observations.

  4. The eBird Taxonomy (v1.05) • User familiarity is the goal • Familiar Clements 6.4 is base global taxonomy • Follows recognized regional authorities for taxonomic and nomenclatural decisions • Standardized English and Scientific Names for all taxa • Translations in other languages • http://ebird.org/content/ebird/about/ebird-taxonomy for download • Personal support for taxonomic questions
