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 correct 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.
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. You can create new checklist templates from your previous lists or import templates created by others. You can import a text file into Birdathon and it will automatically be made into a bird checklist template.
You can export your checklist as a comma-separated-values (csv) text file for import into eBird.
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.
