While we have several ongoing projects evaluating waterfowl use and needs in the Rainwater Basin, we feel sharing how bird populations are estimated is a topic relevant to this time of year.  Our station biologist, Jeff Drahota, compiled a 12 page document with pictures explaining how Sandhill Crane counting is conducted during aerial surveys and how you can learn these skills, too.

The file, Crane Counting 101, is a 2.9 MB PDF document.
