More Geologic Goodies – Buffalo Gap National Grasslands

OK, so the gorgeous yellow-orange Fairburn was the highlight of my rockhounding trip this weekend, but it certainly wasn’t the only “find”.  Here’s a selection of some of the other agates, jaspers, etc.  What amazes me about this location on the Buffalo Gap National Grasslands is the seeming infinite variety of what you can find, all within one very small area. All of these were collected within a one-square mile area.

Prairie Agates - South Dakota

A collection of Prairie Agates, something you find relatively often on the Buffalo Gap National Grasslands, but they’re so pretty and so variable that I can’t help but collect more.

Agate/Jasper - Buffalo Gap National Grasslands

This one was SO striking when I saw it lying there that I couldn’t help but collect it. I admit however that I have no idea what this is…any ideas?

Prairie Agate - Buffalo Gap National Grasslands

A gorgeous prairie agate (or what I’d call a prairie agate), with some very intricate banding and patterns.  The green is a bit of lichen I have yet to clean off. 

Bubblegum Agates - South Dakota

Bubblegum agates! I actually have a somewhat difficult time finding many of these, but always pick them up when I do. Of all the stones out here, it’s the bubblegum agates that really “shine” (ha) when I put them through the polisher. Once you start to wear down those nodules, there are often some truly incredible patterns and banding underneath.

Stones like this make me want to take a hammer and break every stone open. I don’t have a rock saw or anything, but I imagine there are SO many hidden treasures like this on the Buffalo Gap National Grasslands, pieces where you don’t see the beauty unless you slice them open.

A prairie agate. The orangish ones are probably the most common, but there are some pretty red tones in many of them as well.

Agate - South Dakota

While many agates have the banding patterns shown on this post, there are some other cool patterns you find as well. Love the pink “druzy” crystalline area that forms the heart of this agate, with some banding and other patterns around it.

Jasper - Buffalo Gap National Grasslands

A jasper, of which there are many on the grasslands.

Miscellaneous Agate - Buffalo Gap National Grasslands

One more agate (at least that’s what I’d call it), with some interesting fine banding.

Fairburn Agate - South Dakota

An elusive Fairburn agate, from the wonderful rockhounding area of Buffalo Gap National Grasslands in South Dakota. I’m headed there in the morning for a day of rockhounding, so what better time for my first ever ROCK-related haiku of the day? Such a difficult prize to find, as chances are all I’m back tomorrow without one, but OH so worth it when you do find one.

Your garage: A Hummingbird’s worst enemy?

I was working in my yard this afternoon when my next-door neighbor came walking up. She knew I was a bird lover, and wanted to know if I knew how to get a hummingbird out of her garage. It may sound like an odd request to many. However, it’s one I’m getting all too familiar with. I have over 4,000 individual web pages on my South Dakota Birds website. Of all those pages, which page gets the most hits? During the summer months it’s generally not even close…it’s this blog post page from a few years ago, about a hummingbird trapped in my garage.

Once a hummingbird is in your garage, it’s not easy to get them out. My garage, for example, is quite tall, with the ceiling height a good six feet above the top of the garage door itself. Once a hummingbird comes in a garage, their instinct to escape drives them to fly upwards. They really seem to have trouble seeing the open garage door as an escape, and instead seem to always fly up towards the ceiling of the garage. For us, we’ve had two hummingbirds trapped in our garage over the  years, and in both cases, we weren’t able to get them out until they were quite tired from flying around trying to escape. Then we got them to cling to a feather duster while we slowly moved them down and out the garage door. Other people have had some luck luring them down with flowers, hummingbird feeders, or some “red” item that grabs their attention.

And that is the problem in the first place…their attraction to the color red. The item in the picture below may be the most dangerous item for a hummingbird that you have in your entire house or  yard. This is the manual “pull” on a garage door opener, what you use when the power goes out and you want to manually close or open your garage door. The problem is quite simple…garage door manufacturers seem to love making these items red in color. Hummingbirds strongly key in on the color red, associating it with flowers, and thus, nectar for feeding. If a hummingbird goes past an open garage door and sees a red item dangling down, just that attraction to the color red may cause them to enter the garage and check it out.  Once inside, if you have a garage with a ceiling higher than the top of the garage door, they tend to get “stuck”.

We have multiple hummingbirds around our yard from early May through late September. However, with one simple change in our garage four years ago, we haven’t had any hummingbirds inside our garage.  That change? Simply taking the red pull off the garage door opener and changing it to a black item. When I went over to my neighbor’s garage this afternoon, I knew what I would find…red garage door pulls.

Given how difficult it can be to get a hummingbird out of your garage, the best advice I have…prevent their entry in the first place. Check your manual garage door pulls. If they have a red pull, take it off and use a neutral colored item in its place.

Red Garage Door Pull

A typical red “pull” on a garage door opener, for release and manual movement of the garage door. So many manufacturers seem to use bright red pulls such as this. With an open garage door, this is a huge attractant to hummingbirds, who are very easily “trapped” in a garage once they are inside.

No feathers! Not even fur! POTD…

Given we were on vacation for 2 weeks recently, and I was gone on travel for work last week, it’s been a while since I’ve been out birding locally.  With a great forecast temps, light winds, and partial cloud cover, it was shaping up to be a perfect day for bird photography!  I left at dawn this morning with the intention of finding migrating shorebirds and other goodies.

I didn’t want to commit to a long drive up to Lake Thompson where I was pretty much guaranteed of finding shorebird habitat somewhere. Given how wet our summer has been and the rain we had when I was gone last week, I thought there would likely be some standing water around locally…perfect habitat for migrating shorebirds. I was wrong! There were a few areas of standing water, but with crops at almost full height and other vegetation quite lush from the wet summer, most of those wet spots were hidden or surrounded by vegetation. Several did have a few shorebirds, but I never did get any photo opportunities.

The one great photo opportunity for today was a true rarity for me…something without feathers. Something without fur (a target of opportunity I always shoot when out birding). I was driving in western Minnehaha County about half an hour after sunrise, and saw an old…combine (?) in a partially cut wheat field. I say “combine” because it was so old, so simple a piece of farm equipment, that I don’t know what else you’d call it.  Curiously, it was sitting on the fence row right by the road, in a small area of cut wheat in a much bigger wheat field, and with a brightly painted “John Deere” sign facing the road. I couldn’t have designed a better photo opportunity, and with the warm morning light, I spent a good 30 minutes getting various styles of photos of the scene.

With such a perfect scene, I do wonder if it WAS some kind of display that someone had set up, but regardless of why it was there, I thank the owner for providing the photo opportunity!  It turned out to be a great photo day, despite few opportunities to actually shoot birds.

Photo of the Day: Broad-tailed Hummingbird

I was going to go birding today, but alas, my Sjogren’s was flaring up and I wasn’t feeling very good. I stayed home and started processing my (many thousands) of old, unprocessed photos.  I have SO many photos I’ve taken over the years, and so many photos that I have yet to publish online (even on my massive out-of-control website), that I thought I’d start a new feature on my blog…the Photo of the Day. Oh, make no mistake, there’s no way I’ll ever publish a new photo of the day, every day.  Consider it more the photo for THAT day, rather than a series of daily photos. 🙂

First up…one of my favorite photos from our recent vacation to Colorado and Utah.  We visited 12 different National Parks and National Monuments in Colorado and Utah, and as we wound our way through Colorado, we stopped for one night at Winter Park, Colorado. When on vacation, I typically get my birding fix in during the early morning hours, waking before dawn and going out while my wife and son sleep in.  From our room, we could see a trail that ran along the shores of the Fraser River, so I thought I’d give it a try.

I was a bit surprised when I got out that morning, in that the warm summer’s day started out with a chilly 38-degree morning!  I started walking the trail just as the sun came up, but it took 20 minutes or so before the sun peeked over the adjacent ridge and started to brighten the area along the trail. Birds were a bit sluggish at first, perhaps because of the cold.  As I walked along, I saw a tiny bird on the top of a bush. As I approached, I saw a stubborn Broad-tailed Hummingbird, one who decided he wasn’t moving for any reason.

A challenge when shooting hummingbirds is getting the right light for the gorget of a male to “light up”.  I took many photos of this bird, but alas, for most of the time I spent with him, he was facing away from the sun. It wasn’t until I was about to move on that he shifted position, gave me a look, and then turned his head towards the sun.  BOOM…that brilliant magenta gorget lit up in the early morning’s sun as I took photo after photo.  The close range, the detail in the plumage, the clean background, and that gorgeous bright gorget made this one of my favorite photos from the trip.

Blizzard-inspired Drawing – American Woodcock

I don’t draw a lot any more…perhaps twice a year at most.  Not sure why, as I really enjoy it when I do drag out all the colored pencils and give it a go.  With the blizzard this weekend, I thought it would be a perfect opportunity to draw. The species is actually inspired BY the blizzard.  American Woodcocks show up here in early April, and are already on their breeding grounds. They’ve already been doing their spectacular, unique display flights in the late evenings, spiraling up into the sky and diving back down, producing series of twittering and tweeting sounds as they go.  They normally feed heavily on earthworms.  When the blizzard hit, I remembered the posts of people seeing their displays here already this spring, and was wondering how they’d handle the blizzard. Inspiration leading to this, a colored pencil drawing of an American Woodcock.

Macro Mania

As a bird photographer I don’t put on my macro lens very often, but I got it out this afternoon to take some macro photos of the batch of Mexican Crazy Lace agates that I got this past week. Before I started tumble polishing them, I wanted to record what they look like in their natural state. When you zoom in extremely close like this, you can really see the beauty. It boggles my mind that these gorgeous patterns are all made by nature…such variety, such cool patterns, such wonderful colors.

Costa’s Hummingbird – Drawing

I have had zero motivation to do any drawing this year. Literally. The last time I drew anything…New Year’s Eve of this past year. Unfortunately, I’ve also not been very motivated to go out and do much bird photography lately (hence the long time between blog updates).  Today, I was planning on going out, but it was a gloomy, drippy day.  To try to get over my funk, I thought I’d just ignore the crappy news of the world, pick up my pencils, and draw a bit while listening to baseball.

Here’s the result. Not my favorite, and I admit I was getting antsy at the end and just wanted to finish, so there’s no vegetation or background to speak of. One of my favorite species though…a Costa’s Hummingbird. We don’t get them in South Dakota, but we’ve seen them many times on our trips down to Arizona.

Killing Government Science and more — Science, Nature, and Other News

Some news and views from over the last week.  For anyone interested in science, and the huge role that government plays in science in America…it’s been one damned depressing week,as details of the first Trump budget come trickling out. Overall, it’s an absolutely devastating picture for science and environmental funding. A few stories on federal science and environmental funding, followed by some other more cheery stories.

Trump's 4 Horsemen of the Environmental Apocalypse

Seen this week rampaging through the hallways of Federal science agencies were the 4 Horsemen of the Environmental Apocalypse, led by Trump, Steve Bannon, Scott Pruitt at EPA, and, well…one of the original 4 horsemen. I have to include an actual Horseman of the Apocalpyse, as clearly this administration has struck a deal with the devil himself, choosing short term greed and selfishness over the very welfare of the planet.

Trump Budget Kills NOAA Climate Science — Who needs satellites to study weather? And who needs scientists to actually do the science?  Evidently not the National Oceanic and Atmospheric Administration (NOAA).  The proposed Trump budget that has trickled out this week proposes drastic cuts to NOAA, with a 17% cut overall for the program.  For programs that deal with climate change, it’s even more ominous, such as a 26% cut to the Oceanic and Atmospheric Research branch.  Observing what’s happening to our earth’s weather systems? The budget proposes a 22% cut to the satellite data division.  This is a pretty common theme across all of the Federal science agencies, with science evidently something the Nation can afford to sacrifice, so we can build more missiles that are too expensive to actually use, or build outrageously expensive planes that are $164 BILLION over budget and are lacking key functionalities. Government science in aggregate is only 3.4% of the entire budget…yet to pay for a ridiculous $54 billion increase in defense spending (with the U.S. already spending nearly 40% of ALL global military expenditures), science takes a disproportionate hit compared to many other programs.

EPA Budget set for 25% cut — It’s not just NOAA taking a hit.  The Environmental Protection Agency, LONG in the cross-hairs of conservatives who don’t appreciate trivial things like environmental regulation getting in the way of making money, is currently slated to be slashed by 25% in the Trump budget.  The budget proposes cutting 20% of EPA employees, and eliminating or sharply scaling back some major environmental programs. Great Lakes cleanup funds are proposed for a ridiculous 97% cut. Funding for restoring ecosystems in the Puget Sound would be slashed by 93%.  Environmental justice programs would be cut by 79%.  A program to help cut emissions of greenhouse gases such as methane has a proposed 70% cut. I have friends and acquaintances who work for EPA.  The mood there is nothing short of apocalyptic. Wall Street is loving it, given the salivating leaders of corporate America who envision a world without regulation, where they’re free to pollute and destroy the environment, all to squeak out a little bit more in short-term profit.  I’ve said it before…I honestly wonder if any of these people have children, and for those that do, how they can so COMPLETELY ignore their future health, safety, and well-being, all because of short-term selfishness and greed.

Ryan Zinke - Secretary of the Interior

Ryan Zinke, newly confirmed Secretary of the Interior riding his horse to work on this first day. He’s said some of the “right” things in his first few days. He said during his confirmation hearings that he believes in climate change, and that we’re causing it. He’s said he believes science should drive policy, not the other way around. Given a 4% lifetime score from the League of Conservation Voters, we will see if this is just rhetoric meant to placate those who would potentially criticize the direction environmental conservation is going under the Trump administration. Hopefully Zinke realizes the massive responsibility he has for managing our Nation’s lands, and is being honest when he states how important DOI’s scientific research is for supporting sustainable use of those lands.

Department of Interior head “not happy” —  If (just theoretically speaking of course) a scientist was a part of the Department of Interior, things may seem apocalyptic right now as well, but perhaps with just 2 or 3 horsemen of the apocalypse roaming Department halls instead of the full-out 4 horsemen that are set to rampage through some of the other Federal science agencies.  The new DOI secretary is Ryan Zinke, who was confirmed this week, and promptly decided to ride a horse to work for his first day. Rumor has it that Mr. Zinke also has a penchant for proudly proclaiming he’s an ex Navy SEAL, which of course as we all know has direct relevance to managing our Nation’s lands, and the science behind it.  To be fair, Zinke has SAID the right things. As this article points out, he’s “not happy” with the Trump’s proposed 11% cut to Interior.  Few details have emerged so far, but what has become apparent is the disparity in how that cut would be applied across DOI.  Fish and Wildlife is set to take a massive cut compared to other DOI components, primarily because of their role in providing the science that supports the Endangered Species Act.  You can’t enforce the ESA if you don’t have the science behind it, and evidently the strategy of the Trump administration is to simply eliminate the science!  Problem solved, just as eliminating climate science “solves” the climate change issue!  Zinke is a fisherman and hunter, and DOES value the outdoors.  That helps.  Zinke also has a 5% lifetime score form the League of Conservation Voters.  That’s what’s sad, is that someone who has been very environmentally hostile in the past is viewed as a BRIGHT spot in the Trump administration. Here’s hoping that his early rhetoric is actually translated into meaningful action to protect the function of Department of Interior science.  Here’s hoping Zinke means what he says, and he isn’t just saying what’s politically or personally convenient.

Yes, it CAN get too hot for life on Earth — Past theory was that despite the potential for massive global warming to occur, temperatures in the tropics were somehow regulated by an “internal thermostat”, feedback mechanisms that prevented tropical areas from experiencing the same kind of temperature increases found elsewhere in the globe. It was an important theory, because the implication was that the Earth could warm significantly, yet the tropics would be somewhat shielded from that warmth increase, and would still support life. New research demonstrates that this likely isn’t true. The Paleocene-Eocene Thermal Maximum occurred 56 million years ago, a time of the highest global temperatures of the last 100 million years.  Evidence shows that tropical areas did indeed experience drastic temperature increases, increases that resulted in widespread die-off of tropical biomes that couldn’t handle the increased temperatures.  The most drastic temperature increases we’re currently seeing are in Arctic regions, with temperature increasing over two times as fast as the planet on average.  However, as this study shows, there’s no place on Earth that’s immune from the effects of climate change. As this study shows, it IS quite feasible for temperatures to warm up so much that some parts of the earth become inhospitable for life.

Ten million lives saved – Vaccine effectiveness — Certain Trump administration officials, including Trump himself, have expressed skepticism about vaccines, with some even perpetuating the myths about vaccines causing autism and other harmful effects. Here’s one of the BRILLIANT tweets from Trump, showering the world with his “wisdom” about vaccines:

I’m not against vaccinations for your children, I’m against them in 1 massive dose. Spread them out over a period of time & autism will drop!

There you have it, straight from “Doctor” Trump’s mouth. I’m sure he’s done a lot of research on linkages between autism, and the timing of vaccinations. He has some other gems as well regarding vaccines, and there have been some suggestions that he’s partnering with well-known vaccine skeptic Robert F. Kennedy Jr. to assess the “dangers’ of vaccines. Although there shouldn’t be any need to provide more empirical evidence to shut the anti-vaxxers up, new research from the University of Illinois-Chicago has gone to the trouble of quantifying just how many lives have been saved due to the widespread use of vaccines. It was the early 1960s when vaccines against these diseases became widespread, thanks to the development of new human cell strain that allowed for safe and rapid production of vaccines.  According to the research, from 1963 to 2015, over 200 MILLION cases of polio, measles, mumps, hepatitis A, rabies, and varicella were prevented in the United States ALONE. Over 450,000 deaths were prevented by vaccine use. Globally the numbers are staggering, with over 4.5 billion individual infections prevented, and over 10,000,000 lives saved.

Climate change…vaccination use…evolution…the science behind all of these is quite clear. I find it hard to see how any rational human being can deny actual empirical evidence such as that provided in the study above.

The cost of Volkswagen’s deception – 1,200 shorter lives — When Volkswagen installed “defeat” devices on their vehicles from 2008 to 2015 to fool pollutant measurements, it did more than increase air pollution.  A new study shows that due to the lower air quality induced by Volkswagens sold in Europe during that time, that around 1,200 people will have substantially shorter life spans, by around a decade. Volkswagens were emitting 4 times as much nitrous oxide as allowed by European law, contributing to the estimates of premature death for hundreds of Europeans. Retrofitting all remaining Volkswagens on the road is necessary to avoid 29,000 “life-years lost”, and over 4 BILLION Euros in increased health care costs. THIS is the type of world being currently pushed by the Trump administration, where regulation is greatly reduced, and companies like Volkswagen can worry more about profit and less about the health and well-being of people.

Panda "AnAn"

A panda munching on a cookie. Hmmm. According to research released this week, the black ears help “convey a sense of ferocity” to potential predators. I’m not quite seeing the ferocity.

Why Pandas are Black and White — Well, screw the esoteric research many scientists devote their lives to.  Here’s a basic “research “question people can relate to…why are pandas black-and-white?  I’m not exactly sure of the value of the research (I’m sure other scientists might say the same about my research), but they looked at the black and white patterns on pandas and tried to relate to other carnivore species to see if there were survival or adaptation advantages to the black-and-white pattern.  Doesn’t sound like much of a surprise in terms of results. They are largely white because it helps them hide in snowy areas. The black?  The body markings help them blend in areas of dappled light and shade, while markings on their head are thought to help them differentiate among each other and communicate with other pandas. Another supposed finding is that things like the black ears will deter predators by providing a “sense of ferocity”.  OK, it may be pretty basic research, but at least they had me interested until that last point.  I have a very hard time looking at a panda bear and having any “sense of ferocity” conveyed my way.

Seven Earth-like planets a potential hotspot for life — Trappist-1, about 39-million light-years from Earth, is very unlike our sun. It’s an “ultracool dwarf star”, with a temperature much cooler than our sun. However, scientists recently found that 7 rocky, earth-like planets orbit the star, with three of them potentially in the “Goldilocks” zone where temperatures are just right for life. They’re very different than our earth. Given that they’re much closer to their sun, they make complete orbits in as little as 1 1/2 earth-days for the innermost planet, to around 20 days for the planet furthest from Trappist-1.  They also are likely gravitationally locked, with the same side of each planet always facing the sun. The next step will be to try to take measurements of the atmospheric composition of each planet, which will give clues to the potential for each to host some form of life.

Refugee scientists on the run, scared — From Nature.org, a fascinating story of “refugee scientists”, scientist from regions of conflict like Syria who have had to adapt to keep their research alive. Not to mention their very lives. Obviously scientists are only one small segment of the populations that are affected by these conflicts, but stories like this really help put a human face on things. The article provides the stories of four different researchers and the lengths they’ve had to go to to escape their home countries and rebuild their lives.

Women feel more pain then men? — According to new research from scientists at Georgia State University, women feel more pain on average than men because cells in their brains that process pain signals are more active than those in men.  Guys, I hate to say it, but this REALLY makes us look like wimps. During cold and flu season such as right now, there are plenty of stories of men being incapacitated for days by a virus, while the women in their lives soldier on and struggle through it without stopping their normal lives. I guess I had always held out hope there was some biological driving force behind the general wimpiness of men, but no, evidently even biology favors more pain-free lives for men.  We have no more excuses guys…we truly ARE wimps.

 

SuperB Owl Sunday – Drawn Owl Edition

And along with the photos, owls have been one of my favorite species to draw.  I haven’t really done all that many drawings since I took up colored pencil drawing about 5 years ago, maybe 30 overall, but I have drawn three different owl species.

Barn Owl Drawing - Tyto alba

Drawing of a Barn Owl, a species I’ve had glimpses of on occasion, but have never had a good photo opportunity. That was the reason behind many of my bird drawings…to fill a “hole” in my photo collection of species I had no photos for!

Boreal Owl - Aegolius funereus

A few years ago I made the 6+ hour drive to Sax-Zim bog by Duluth, Minnesota, to look for Boreal Owls. They’re a rare find in the lower 48, but that winter, a number were seen in the area. Alas, I struck out and didn’t find any, so I did the next best thing…come home and draw one.

Northern Saw-whet Owl Drawing - Aegolius acadicus

A Northern Saw-whet Owl. These are the little guys I tried SO hard to find a couple of years ago, and I was finally rewarded by finding several near Sioux Falls. Love these little guys so much that I thought I’d try drawing one as well.
