    Great post. Maybe more than most things in life, knowing the name (even better, names) of a bird. Thank you for also sharing the origins and meanings of the names.

    A wonderful collection of photos! I’ve yet to see the thick-billed variety. That would mean travel! 🙂 Thanks for this great post.

ABOUT THE SITE

With a primary focus on birds, each blog series has it’s own unique look at the wildlife and wild places encountered at different locations that I have visited around the world.

ABOUT ME

I earned my college degree in biology, a foundation that shaped not only how I see the world, but how I’ve spent my life sharing it with others. For more than 40 years, I taught and led in public education, helping students discover the wonder woven into every corner of the natural world. That same drive has carried me through decades of citizen science and conservation work. As an active member of the Modesto Camera Club, I’ve developed a photographic practice that blends natural history with visual artistry, and my award‑winning images have been featured across the Internet on dozens of sites and field‑oriented platforms. This blog brings together my passions for birding, conservation, and storytelling.
