Pat O’Donnell over at Costa Rica Living and Birding maps out a potential hummingbird-only big day route that could net the ambitious birder forty species of hummingbird in one day in Costa Rica (and potentially more). That made me wonder – what is the single day record for seeing the most species of hummingbird?

The answer, apparently, is a whopping 41 species! Nick Athanas, Iain Campbell, Paul Coopmans, and Richard White set the record back in March of 2002 in Ecuador and I can find no record of someone having topped that mark since.

This does beg the question – what is possible in terms of a hummingbird big day? And who will try to top the record?
