This is implemented as a client-side binary search of a 3GB file using HTTP Range-Request, which I'm pretty satisfied with.
One more highlight: there are 92 eBirders with a most frequent country of "Antarctica." They form a small little cluster near Patagonia.

Citizen science data always contains geographic biases, and eBird data is no exception. There isn't enough intra-Africa connectivity in eBird data for the world's second largest continent to show a clear cluster.

The United States dominates eBird data. Scattered within the United States' large cluster, there are a number of birders who most commonly bird outside of the United States, but are very connect to Americans (often from different states.) Perhaps professional bird guides?

Even if you have an account, it's really confusing. You might think that each of these $2.90 charges corresponds to a subway ride towards the cap. You would be wrong! Two of them are AirTrain charges (from the same ride but processed on different days, and weirdly bundled with other trips.)

This "Democratic" PAC has not made any campaign contributions or transfers with the $1.8 million they have raised through misleading emails. But they did spend $427,000 of that cash to buy more text message and email spam lists from data brokers.
