On May 23, I decided to go up to Lake Cuitzeo, in spite of the fact that the lake can seem much less interesting after our winter migrant ducks, waders and shorebirds have left. And it also turned out, to my great surprise, that not all those migratory ducks had left yet. 2020 yielded a single sighting; 2019, two; 2018, four.

This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. Jon Fjeldså’s contributions include many of the ducks, yellow-finches, and many other families where his images of Birds of the High Andes could be used. Clearly, this is an under-birded country. .
