An incredible, polished bubblegum agate from the Buffalo Gap National Grasslands of South Dakota. An amazing little piece, it was a small, black, featureless lump when we found it, but we’ve found that these little dark bubblegums often have some GORGEOUS patterns that reveal themselves once you polish them for a while. There are other examples on the updated pages on South Dakota Rockhound pages.
I’m 51 years old. I already have so many unprocessed bird photos sitting on my hard drive that I doubt there are enough years left in my life to process them all, and add them to my website or blog. It’s easy to take photos! It’s FUN to take photos! It’s much less fun to process them all and DO something with said photos.
And now my son and I have a new hobby that we started last summer…rockhounding in the incredible areas near the Badlands of South Dakota. We certainly have found some beautiful pieces of agate, jasper, petrified wood, and other stones over the last year. The wonderful and variable patterns and colors just BEG a photographer to get out the camera…I can’t resist! As if I needed more unprocessed photos cluttering up my hard drive, now I’m also taking macro photos and photos of rocks and minerals, many of which will likely never see the light of day.
I’m trying! I’m trying to be more selective in what I shoot, both for birds and for rocks! And in an effort to at least get some photos of my favorite pieces out on my website, I have just recently updated the “South Dakota Rockhound” section of my website. Click on the following for photos of some of the pieces we’ve found over the last year. There are also some cool macro photos of other mineral assets we’ve acquired over the past year (for now, just a batch of Mexican Crazy Lace agate). As with the birding pages on my website, I’ll try to continually update the Rockhound site as I have time! For now, enjoy the new photos.

An easy ID for many birders…a Western Scrub-Jay! WRONG! There is no longer a species called a Western Scrub-Jay. Instead, there are 2 individual species called “California Scrub-Jay” and “Woodhouse’s Scrub Jay”. This is a California Scrub-Jay, taken at Point Reyes National Seashore in California.
Remember 2 or 3 days ago how I said I couldn’t keep up with all the changes to the “official” American Ornithological Union (AOU) and American Birding Association (ABA) changes on their North American checklists? That my North American Birds – Information and Photos page had nearly all the recognized species, but there were many changes in scientific names, species names, and taxonomic order that hadn’t been updated for a while? I spent the last two evenings taking care of it all, and am glad to say that my that my main species page is now completely up-to-date. The taxonomic order now matches the AOU, all species and scientific names are correct, and I necessarily added a few pages for “new” species.
In terms of “new” species since I last updated the page, the newest was a AOU split of what was formerly the Western Scrub-Jay into two distinct species. I now have a California Scrub-Jay (Aphelocoma californica) species page and a corresponding species range map page, as well as a new Woodhouse’s Scrub-Jay (Aphelocoma woodhouseii) species page and a corresponding species range map page. I was fortunate enough to have my own personal photos of both species, with several photos of California Scrub-Jay from around the San Francisco area, and a few photos of Woodhouse’s Scrub-Jay from around Tucson, Arizona. One other “new” species split that I was behind on was the split of what was formerly the Sage Sparrow. I now have a new Sagebrush Sparrow (Artemisiospiza nevadensis) species page and range map page, as well as a new Bell’s Sparrow (Artemisiospiza belli) species page and range map page. Unfortunately I don’t have my own photos of either, although I at least have seen the Sagebrush Sparrow side of the split.
Taxonomic order changed quite a bit from my old version, which took a while to fix. I went through all ~980 species to check scientific names, and was surprised how many had changed since I last updated my species pages. The Warblers in particular had many, many changes in scientific names (no more Dendroica! Many more Setophaga!).
All up-to-date now though! Come next July, when the AOU releases their 2017 updates, I’ll try to keep up on my web pages!
A Hoary Redpoll in my crabapple tree. For now, I can still count a Hoary Redpoll as its own species, as the AOU committee decided to hold off on a proposed action to merge Hoary and Common Redpolls into one species. Which means for one more year, I can proudly proclaim that I’ve had a rare Hoary Redpoll in my yard.
It’s damned hard trying to keep up with all the official changes on the American Birding Association’s (ABA) North American birds checklist! The ABA list is generally based on the checklist from the American Ornithological Union (AOU). Every year, the AOU Checklist Committee considers formal proposals to change the checklist, with recommendations coming from scientists who have published research and other materials that may support a checklist change. Every July The Auk (the journal for the AOU) publishes the changes for the year. And every year, I either ignore those changes, or spend several months delaying any related changes to my website.
Ever since I started my website more than 15 years ago, I’ve been working on having individual species pages for each species seen in North America. Especially when a new species is added, I try to keep up and edit my checklist and summary pages, but I admit I’m behind in doing so. If it’s simply adding a new species (for example, if an exotic species is now established enough in the U.S. that the AOU considers it a new, permanent species in North America), it’s easy enough to add a page. I’m fairly caught up with those changes. What’s a major pain in the butt is trying to keep up with the “order” changes. Every year, they make changes in the official “order” that species are listed in the checklist. The AOU checklist is presented in a “phylogenetic order”, using DNA and other information to “rank” species according to their origin and where they are on a evolutionary tree. Basically, more “ancient” species are listed first, while species more recent in origin are listed last. On my pages, for example, I still have finches “ranked” very near the bottom. However, in recent years finches have received a “promotion”, and are now higher on the phylogenetic order list. It’s a major change moving things around on my master species page, thus the order changes that have occurred in recent years are those changes least likely to be represented in my checklist and species pages.
Here we are in mid-December, a mere 5+ months since the latest updates, and I’m finally taking a peek at the changes. Looks like I have more work ahead of me on my website, particularly if I want to update the checklist order. Some highlights of the changes for the year:
- Scrub Jay species — I have a new species on my life list, thanks to a new species split! The Western Scrub-Jay has been split into two distinct species, the California Scrub-Jay (Aphelocoma californica) and Woodhouse’s Scrub-Jay (Aphelocoma woodhouseii). The California species is found from Baja California northward into Washington state, and is darker with richer colors, while the interior species is found in the dry interior of the southwestern U.S. and is paler in appearance. When a species is split like this, it’s sometimes hard to know which of the new species you’ve seen, but fortunately I have photos of the former Western Scrub Jay from both California and Arizona, meaning I’ve seen (and photographed) both new species!
- Leach’s Storm-Petrel split — The Leach’s Storm Petrel has been split into 3 distinct species. Given a pelagic species such as a storm petrel isn’t exactly native to South Dakota, it’s not one I’ve seen, but alas, it still means a needed change on my website.
- Changes in scientific names — I won’t pretend that I understand why scientific names of species are sometimes changed. Most of the changes this year are for shearwater species, but I saw they also changed the Sandhill Crane from Grus canadensis to Antigone canadensis.
- Substantial changes in the phylogenetic order — Of course. Sigh. A hard one to keep up with, and once again this year, these are changes I’ll likely ignore on my website. Especially once you’ve been birding for a while and have used the same field guide for years, it’s tough even in your own mind to mentally adjust to a different “order” of species.
- Redpoll species — My “best” yard bird without question was a Hoary Redpoll that showed up 3 or 4 winters ago. That winter was the only winter I’ve ever even had Common Redpolls in my yard, but one day my son looked out at several redpolls on our thistle feeder and asked “what’s the white one”? It wasn’t exactly white, but there was a Hoary Redpoll that was very obviously different than the Common Redpolls around him. For years it’s been speculated that the Hoary Redpoll really isn’t a different species, that it’s just a plumage variation. The AOU committee decided for now to hold off on lumping the two into one species, so for now, my best yard bird still holds!!
