Birders who submit their checklists to eBird likely know that their data may be used to conduct research on avian migration, range, or population. It has also been used by researchers from other fields, such as economists. I emailed the Dr. Lopez and asked about this research and the use of eBird data.

It is not an encyclopedia, though it does summarize research, explain basic concepts, and ends with a section on bird statistics. It is a fascinating book that teaches while it entertains, that offers research-informed arguments for bird protection and conservation in the guise of vibrant design. Intriguing, isn’t it?

The Northern Spotted Owl is a “ threatened ” species under the U.S. Endangered Species Act and it was famously the subject of extensive and protracted litigation in the late 1980s and early 1990s, mostly relating to forestry management plans in the Pacific Northwest. A sample of this process is here.)

They are a commensal species, meaning that they are a wild animal that lives in close association with humans, not as a pet or as a farm animal but more like a parasite, to the extent that it is hard to find them in truely wild settings, and it is hard to find human settlements without them.
