  1. Domain-centric observation networks: Experiences gained from the Avian Knowledge Network Denis Lepage Bird Studies Canada

  2. Avian Knowledge Network • Network of North American Institutions collecting or using information on bird populations • Many dozens of data providers and already several active nodes • 50-60 million records currently available (Oct. 2008)

  3. A.K.N. is not an abbreviation for AeKidNa:

  4. Goals of the AKN • Organize heterogeneous datasets on birds through a network of AKN nodes • Provide long-term archive and redundancy • Make those datasets accessible in a common format • Facilitate and create analysis and visualizations

  5. AKN nodes Cornell Lab of Ornithology Point Reyes Bird Observatory Bird Studies Canada

  6. Roles of the nodes • Primary data custodians (data quality, metadata, etc.) • Act as data brokers for partners • Access points for raw data • Portal for real-time data analyses and summary presentations • Analyses tools based on AKN standards

  7. Bird Monitoring Data Exchange Schema (BMDE) • Extension of DarwinCore schema • Protocol fields • Effort • Unique identifiers (eg, SamplingEvent) • Absence data • Probabilities / Relative abundance

  8. Mapping abundance Breeding Evidence (presence/absence) Relative Abundance from Point Counts
