Sighting Analysis

Every checklist you've ever submitted, ready to explore.

eBird is built for collecting and sharing sightings across the global birding community. Yearbirder helps you explore your own personal sightings in depth — through sortable lists, totals, more than 30 chart types, and more than a dozen interactive maps, all filtered any way you choose.

The Yearbirder main window with the Sighting Filter and a species list

The main window: set a filter once, then open any list, chart, or map from it.

Lists for every question you can ask

You can generate any variety of lists: county lists, state lists, date lists, lists of checklists, lists of locations — all filterable however you see fit. Create custom lists, like every sparrow you've seen on an April day in San Francisco County between 2008 and 2017, or a list of every location where you've seen a Western Kingbird.

  • Filter simultaneously by region, family, species, date range, and season
  • Compare any two species lists side by side
  • Sort any table by any column instantly
  • Individual species window with full sighting history and monthly patterns
  • Location window with complete history, yearly breakdown, and a map

Totals and the Big Report

Date Totals shows your species counts by year, month, and individual date. Location Totals breaks down your counts by region, country, state, county, and named location. The Big Report pulls it all together in a tabbed view — species, dates, locations, and checklists at once.

  • Date Totals by year, month, and day
  • Location Totals by region, country, state, county, and location
  • The Big Report — species, dates, locations, and checklists in one tabbed view
  • Drill from any total straight into the underlying sightings

More than 30 chart types that reveal the big picture

Numbers alone don't tell the story. Yearbirder turns your data into charts that make patterns visible at a glance — from how fast you found new species each year to which locations dominate your checklist count.

  • Species bar graphs, accumulation curves, and heatmaps
  • Top-20 locations by species count
  • Checklist scatter plots by duration and season
  • Phenology chart — sighting dates plotted by day of year
  • First and last sighting of each species per year
  • Year-to-date bar charts comparing every year side by side
  • Pie charts by family, order, or location

  • All sighting locations plotted on a global zoomable map
  • Animated lifer map — watch your life list build dot by dot
  • First-sightings map of where you first found each species
