But it is the height of migratory season here in central Mexico, and that made me also spend some time thinking about this issue of connectivity, and the artificial separations we humans attempt to create. I have left out dozens of migratory species, often because their breeding range covers too much of North America to consider in this way.

It was always thought that humans first inhabited the island of Madagascar about four or five thousand years ago or so. It was after that date that many of the great and strange animals of that island went extinct, presumably because of human hunting. If they are the only evidence of humans, then not fine.

I want to alert you to a recent study (from April) that looks at the plight of bird populations under conditions of climate change in Europe and North America.

Over the course of nearly 15 years, James Paruk of the Biodiversity Research Institute and his colleagues used a combination of methods to investigate winter site fidelity at four locations across North America and found that birds had an 85% chance of returning to a site in subsequent years. Here’s one of the maps from that paper: *FIGURE 1.

You might think that birds don’t change the world, birds are the world – but by his odd title, Ten Birds That Changed the World, author Stephen Moss means, he says, that birds have, in various ways, led to “paradigm shifts” in human history. Maybe Moss is right, and birds have changed history. What claptrap.

We humans have a very deep and powerful urge to assemble individual data points into some sort of larger construct — to label and categorize them and understand how they relate to other things we know. Suddenly, hoatzins are no longer strictly birds of the Neotropics. And Mayr et al.
