Since late 2019, the eBird development team has been working to update the eBird database to an improved version. Some older tools were too outdated to be easily updated or were duplicated by newer eBird tools. Examples include Summarize My Observations, All-Time First/Last Records, Arrivals and Departures, and High Counts.
If you are looking for Summarize My Observations, please stay tuned for a new checklist summary tool in the coming year—we are modernizing the tool in a way that’ll make it even better than before.
If you are looking for All-Time First/Last Records, Arrivals and Departures, or High Counts, please refer to the ‘Explore Regions’ tool in the upper right of the eBird Explore page. The majority of these features are available by searching for the region of interest.
Thank you for your understanding, and for being a part of eBird!
