Subject: [sbcobirding] a 40-year progression of the Santa Barbara County species total
I am writing a short history of the evolution of my missive "The Birds of Santa Barbara County, California" (BOSB) for the Santa Barbara Audubon Society newsletter. A little aside that this project generated was how the total number of species recorded in Santa Barbara County has surged forward over the past 40+ years. The totals (without the Channel Islands) have been as follows:

1982 (my original Masters thesis version of BOSB):  412 species

1994 (book version of BOSB published):  454 species

2025 (online version of BOSB as of 1 July):  506 species

So, quite the surge in the number of species over all these years. If one includes the Channel Islands, that adds an additional 4 or 5 species.
