Birdathon

Birdathon is a tool for recording your bird observations, organizing your bird checklists and sharing your birding adventures with others. Use Birdathon in the field to quickly record whether a bird is seen or heard and the number observed. The time and location of each observation is automatically recorded. You can adjust the location, time entries and the count of birds observed at any time to ensure your records are accurate.

Checklist maps display the locations of your observations. You can overlay county boundaries for every US state. You can add a range circle such as a 5MR (5-mile Radius) to your maps. You can import and overlay custom kml files onto your maps.

Your checklists can be viewed in taxonomic order, alphabetically, by rarity or as a timeline of birds in the order observed. You can enrich your checklist with field notes and add observations such as mammals, butterflies, wildflowers, etc., to make it into a rich record of your experience. You can organize your checklists into categories such as Day List, Year List, County List, Life List, etc., and assign color themes to your lists.

Bird species may be added and deleted from your lists at any time. You can create new checklist templates from your previous lists or import templates created by others. You can change which template is being used. You can import text files into Birdathon, making them into templates or new checklists.

Different export options for your checklists let you import into eBird or into another copy of Birdathon.

A Summary view aggregates bird observations from all your checklists across different time spans (week, month, year, etc.) and geographic locations, sorting the information in various ways. Summary maps and lists can be restricted to a specific geographic range. You can export Summary data into a csv text file or create a new checklist template from the Summary.

The bird species source data and other resources used in this app come from the following sources:

ABA Checklist derived from the American Birding Association's checklist of North American Birds. http://listing.aba.org/aba-checklist/. Used with permission.

Santa Clara County Checklist derived from the Santa Clara Valley Audubon Society's Santa Clara County, California Bird Lists, maintained by Brooke Miller. https://scvas.org/sc-county-birds. Used with permission.

World bird family names and world birds come from the Clements Checklist, from the Cornell Lab of Ornithology’s eBird/Clements checklist of birds of the world. https://www.birds.cornell.edu/clementschecklist/download/. Used with permission.

Alpha codes come from The Institute for Bird Populations’ Standardized 4- and 6-letter Bird Species Codes. https://www.birdpop.org/pages/birdSpeciesCodes.php.

County boundary data is from the United States Geological Survey (USGS) TIGER/Line 2019 Shapefiles found on the United States Census Bureau's website at https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.2019.html. Boundaries should be used as general guidelines and not be considered precise. Note especially where county boundaries follow creeks, rivers, ridge lines and other natural features, and so are of much finer resolution than can be shown on Birdathon’s maps.
