In an ideal world eBird would have very densely-spaced data points being sampled repeatedly across the landscape. But we know birders aren’t evenly distributed out there, and getting off the beaten path can be a challenge. We hope these maps help show you where eBird needs more data, and where your birding effort can make a bigger impact on our ability to model birds in your county.
Bird distribution changes with the seasons, and at eBird we like to have data distributed throughout the year to track the ebb and flow of bird populations. With this in mind, we plan to update these maps each month so that eBirders will have a better idea about how the data volume changes in each state and county. Check back to see the maps for August around the 1st of the month.
