Cerulean Warbler Technical Group, Golden-winged Warbler Working Group, Cornell Lab of Ornithology and National Audubon Society Unknown database http://ebird.org/content/primig Priority Migrant eBird is a project developed by the Cerulean Warbler Technical Group, the Golden-winged Warbler Working Group, the Cornell Lab of Ornithology and the National Audubon Society. Priority Migrant eBird collects distribution and abundance data for five birds that migrate or winter in Central and South America. Detailed data on non-breeding distributions are needed to generate effective rangewide conservation strategies for long-distance migratory species that have experienced recent precipitous population declines. The five species are Cerulean, Golden-winged, Blue-winged, and Canada warblers, as well as Olive-sided Flycatchers! Priority Migrant eBird is one of several regional eBird portals that exist (aVerAves, Vermont eBird, Mass Audubon eBird, Texas eBird, Bird Conservation Network eBird, Gulf Coast Bird Observatory eBird etc.). Each contributes to the cumulative eBird database. The goal of Priority Migrant eBird is to collect the non-breeding season distribution information needed to generate effective rangewide conservation strategies for long-distance migratory species that have experienced precipitous population declines over the last few decades. The project was initially conceived by the international committees of the Golden-winged Warbler Working Group (Alianza Alas Doradas) and the Cerulean Warbler Technical Group (El Grupo Cerúleo) as a tool for addressing the lack of information on non-breeding season distributions for these two species in Central and northern South America. In order to maximize the number of contributors among the banding, conservation, research, education, and birding communities, and to minimize the effort needed to contribute records, these groups decided to use the power of eBird to facilitate data entry and to produce exciting output products that will be able to track the dynamic distributions of high priority species. eBird data are stored in a secure facility and archived daily, and are accessible to anyone via the eBird web site and other applications developed by the global biodiversity information community. For example, eBird data are part of the Avian Knowledge Network (AKN), which integrates observational data on bird populations across the western hemisphere. In turn, the AKN feeds eBird data to international biodiversity data systems, such as the Global Biodiversity Information Facility (GBIF). In this way any contribution made to eBird increases our understanding of the distribution, richness, and uniqueness of the biodiversity of our planet. 19000101 2009 ground condition In work Continually Data may be entered for anywhere in the Western Hemisphere. 160.00000 -40.00000 90.00000 -80.00000 None checklist bird movements range ranges migratory pathways wintering breeding arrival dates departure dates range expansions range contractions important bird areas population trends distribution migration None Wisconsin Illinois Indiana Chicago Chicago Wilderness None spring summer fall autumn winter January February March April May June July August September October November December None multiple species birds waterfowl waterbirds game birds seabirds raptors shorebirds landbirds songbirds Golden-winged Warbler Cerulean Warbler Olive-sided Flycatcher Blue-winged Warbler Canada Warbler American Ornithologists' Union 1998 Seventh book The check-list is revised and updated on an annual basis by the American Ornithologists' Union.

We gratefully acknowledge the efforts of the thousands of volunteer observers who make this project possible. The data are maintained in an Oracle database at the Cornell Lab of Ornithology. Macromedia Flash Player is needed to see maps or graphs on the eBird "View and Explore Data" web site. A link to the Macromedia Flash Player download site is provided on the eBird site. These data are collected by volunteers of varying abilities. Many steps are taken to ensure that the data are as complete and accurate as possible. After completing the data-entry for a checklist, a summary is provided for review. If anything is incorrect, the observer can go back and fix it. CONFIRMING UNUSUAL ENTRIES Various filters are used during the online data-entry process to check for unusual data. These can be, for example, a species out of its normal range or an unusually high count for a particular species. If an observer submits an unusual observation for the date and location, they may be prompted to confirm the entry. If it is a typographical error, they can simply correct it. If they are sure the entry is correct, they can check a box labeled "Confirm" next to the species� name on the checklist. These "flagged" observations are uploaded to the eBird database and are available under the View and Explore Data features that access the observer's personal observations. However, they aren't immediately available in the publicly accessed View and Explore Data features. Instead, they will appear on a password-protected alternate site where a local expert will review the observations. We've taken this precaution for two reasons: to ensure the identity is correct, and to be made aware that an unusual bird was present. In some cases the observation may be a rare sighting, in which case the editor will contact the observer directly via email for additional details. This process serves to double-check the identity, ensuring the quality of the eBird database for scientific use. In many cases an observation may be expected, but of interest to a local checklist committee. It may be flagged to alert the people who monitor these sightings and need to be alerted as soon as possible. In these cases, the observation will be "unflagged" without any follow-up contact, making it accessible to the public through the View and Explore Data features. not applicable There are four basic methods of reporting birds on eBird, each with a different set of required fields. Observers are allowed to enter data for all species they identified or for only a subset of the species, but they must indicate which it is. Locations are stored as latitude and longitude coordinates, but the accuracy of the coordinates varies. Observers can select a location from a list of predetermined "Birding Hot Spots" or they can enter the latitude and longitude directly, find the location on the eBird interactive map, or simply enter the observations at the state, county, or city level. Field None checklist sighting count area search Observers report the location, species, and number of birds they see and/or hear. There are four basic methods to report birds on eBird, each with a different set of required fields. The four observation types vary in the amount of effort used to make the observations. CASUAL SIGHTINGS: don't require any measure of time spent, distance traveled, or area searched. Casual Sightings simply denote that a given species was present at a particular location on a certain date. STATIONARY COUNTS: made over a known period of time, but don't include any measure of distance traveled or area searched. TRAVELING COUNTS: made when traveling a known distance and period of time while walking or using a horse, car, boat, or some other transportation. EXHAUSTIVE AREA COUNTS: made while thoroughly searching a given location or area. These counts are sometimes used by biologists when monitoring a specific site, but they can be appropriate for casual birding if the observer is able to estimate the size (in acres or hectares) of the area that is searched. Home, office, etc. None data entry Observations are reported by using the interactive online checklist. The checklist displays all of the species on the version that is selected (Most Probable or Full), sorted in the order that is selected (Taxonomic or Alphabetic). For each species that is identified, the number of individuals that were counted is entered. If a count or estimate was not obtained, an �X� indicates that it was present. After completing the checklist, a summary is provided for review. If anything is incorrect, the observer can go back and fix it. Once the checklist looks OK, it is submitted and is immediately available using the View and Explore Data features.

The minimum data fields collected are location, observation type, date, if reporting on all species identified, species name, and count (or presence). Locations are given a name and are also stored as latitude and longitude coordinates.
