Vagrant Cassin's Sparrow specimen from Chicago

A Cassin's Sparrow meets its end a long way from home

Every day during fall migration, the Chicago Bird Collision Monitors deliver to the Field Museum a bag of birds that died flying into windows in the loop as they tried to make their way south to their wintering grounds farther south. These salvaged birds provide a critical component of the museum's bird collection, specimens that can be used by researchers for generations to come to learn about many aspects of our area's birdlife.

How many trees are there in the Amazon?

A couple of weeks ago some colleagues and I wrote a paper in Science reporting some new findings on Amazonian forests. Some of the findings are actually just numbers, and one of those numbers is really big. It's the number of trees we think probably grow in the Amazon, and it's 390 billion.

Species in a world that thinks there is a clear division between basic and applied science

Humans are an inconsistent lot, but you would think that might not apply as much when it comes to science, and yet it does.  Even in science are still plenty of ways in which topics lead to opposing and confused viewpoints.  Around my institution these days the terms “applied” and “basic” science are being kicked around at the same time we are discussing “species” as a theme that cuts across research programs.
