The coastal subspecies of California Gnatcatcher ( Polioptila californica californica ) can be found in sage scrub that was once abundant from Ventura County to northern Baja California. As a result, the bird has a long history with the Endangered Species Act. FWS released a 5-year review of the species in 2010.

The potpourri covers some interesting bird related science of the last few weeks, and the promise is this: I’ll get to that other stuff soon, I promise!

Thus, I can pinpoint my first pelagic trip, as it added 13 new species. and Canada. For example, I’ve seen Bald Eagles in 15 states.

Manker’s thesis is that ornithology is an excellent gateway to students becoming science majors in college and, more broadly and longer-term, conservation-minded citizens. That article left an impression and I have wondered what became of Manker’s effort to create a high school ornithology curriculum. Think about it for a minute.
