Unexpected surprise at the feeders – Common Redpolls

Common Redpoll - Acanthis flammea

From the big Redpoll invasion of 2013, a Common Redpoll sitting on a sunflower head in our yard. This week on Halloween, we had our first Common Redpolls since 2013.

We’re at a part of the season that isn’t a lot of fun for a birder in South Dakota. As the calendar flips from October to November, we’re fully entrenched in the “dry season” for birding, where both bird diversity and bird numbers are far lower than in the warmer months. Most of the smaller water bodies in the area are starting to freeze over, and while there are still some waterfowl and gulls hanging around the open water in the bigger lakes, it won’t be long before they too depart for the winter. Nearly all of the insectivorous birds too have long left the state, leaving us with our typical winter mix of species.

Dark-eyed Juncos are now found scattered throughout my yard.  A welcome addition to an otherwise dreary winter in the yard, but…when the Juncos are around it’s a sign that winter is starting to arrive. In addition to my House Sparrow hoards, I’m also getting an occasional surprise sparrow species, such as the Harris’s and Lincoln’s Sparrows that have periodically showed up in the yard. I am now getting regular visits from three woodpecker species (Downy, Hairy, and Red-bellied), another nice presence during the winter months. But overall the species that dominates my yard right now are American Goldfinches.

My wife bought me a huge, tall thistle (niger) feeder many years ago, and it’s always been a star attraction in my yard. The goldfinches will use it all season long, disappearing occasionally for a few weeks at a time, only to come back in full force and stay for long periods of time. Lately, as the weather has gotten colder, the finch feeder has been standing room only, with every available perch often full during the day. The goldfinches may not be in the brilliant yellow summer plumage, but the activity and quiet chatter is nice to have around.

Hoary Redpoll - Acanthis hornemanni

A Hoary Redpoll, a pale, beautiful, wonderful surprise later in that winter of 2013. The two that hung around my yard for several weeks are still the only two Hoary Redpolls I’ve seen in South Dakota.

On Halloween this past week, I was working at home when I came downstairs to grab some lunch.  As I was letting the dogs out into the back yard, I couldn’t help but notice some oddballs in the American Goldfinch hoard that scattered when seeing the dogs. Most of the flock landed in my very large River Birch at the back of the yard, and at first I thought the oddballs were just House Finches.  But after the dogs finished their business and came back in, I was very pleasantly surprised to see a handful of Common Redpolls scattered in with the Goldfinches that were returning to the feeder.

We’ve been in South Dakota for 24 years. In those 24 winters, there have only been 3 occasions where I’ve had Redpolls in the yard. One of those occasions was a “one-night stand”, where a few were at the feeders briefly and then disappeared. But from January through March of 2013, my yard was inundated with Redpolls, to the point that Redpolls actually outnumbered the ubiquitous Goldfinches most days.  It was a snowy and long winter (they all seemingly are), but having the Redpolls around made it seem a little less gloomy.

Much to my surprise, the Common Redpolls weren’t even the best surprise that winter. One morning my young son looked out at the feeders and said “what’s the white one?”  He saw a bird among the Common Redpolls at the finch feeder that was obviously different. I went over and looked out, and was rather shocked to see this wonderful, pale Hoary Redpoll mixed in with the Common Redpolls. A life bird, all from the comfort of my cozy sunroom window!

We had one, and then two, Hoary Redpolls stay around the yard for several weeks before disappearing, along with the rest of the Common Redpolls. We haven’t had Redpolls in the yard since, until this Halloween day! I’ve got a glimpse of one Redpoll in the days since, as my finch feeder has returned to being dominated by goldfinches, but I’m hoping the Redpolls are still around, and plan on staying around for the winter. It would bring a VERY welcome splash of color and diversity to our limited suite of winter birds in South Dakota.

Scientists are Assholes

I’m a scientist. I’ve been in my field for over 25 years, employed at the same place for the vast majority of that time. I’ve got a many peer-reviewed journal publications, and have been around science and science publishing long enough to realize that…

Scientists are assholes.

Scientists have egos. I think for any successful venture, including scientific research, you HAVE to have a healthy ego, a confidence in your own capabilities, and a confidence in what  you’re doing. But underlying the “confident” form of ego is the seedy underbelly of scientists acting like assholes.

The New York Times posted a wonderful piece that focuses on social psychology, but the same general storyline could have played out in any of the sciences. In short, a young scientist published an article in 2010 that summarized one piece of her research. That led to notoriety, and even a 2012 TED talk that become one of the most widely viewed talks ever. After basking in the glow of the work for a short time, other researchers began to question her methodology, and question her results. Even worse, it got personal, with scientists and science bloggers taking the young woman to task, making unfounded and hurtful accusations. In short, the young woman DARED to experience success…which triggered a backlash from other scientists, a group of human beings that love NOTHING more than to tear each other down.

Scientists are assholes. At least there’s a segment of the profession that act in this manner. Many of them have built careers not on perfecting their own new, original research path, but instead by tearing apart the work of others. Even in my own field, there are scientists who I am only aware of because of their published “bakeoffs”, assessing the collective work of OTHER scientists, and meticulously picking through the work to find (perceived) flaws.

Given my cynical nature, it’s not like being an asshole is restricted to the field of science. So why devote a blog post to trashing my own profession? To make a point about climate change science. Climate change skeptics are nearly ALL politicians…talking heads…pundits…but very rarely, actual scientists. Even the majority of “scientists” who do attempt to discredit climate science are not climate scientists themselves.  Most often they are from another field. The pool of real climate scientists that are skeptical that 1) the climate is warming, and 2) mankind is at fault is TINY.

Scientists are assholes. And yet among scientists, climate change discord is remarkably absent. In a profession where ego and competitiveness are sometimes out of control, I can think of no better evidence of the sound scientific basis behind anthropogenic climate change. IF there were any speck of credible evidence that the climate isn’t warming, or that mankind’s activities aren’t the primary cause, stories such as the one provided by the New York Times would be rampant. Scientists would be eagerly ripping apart each other’s work, trying to discredit not only the research, but the researcher him/herself.

 

Christmas in October!

I think my favorite part of tumble polishing stones…taking them out from the first time they enter a rough polishing phase. Many at that stage are odd shapes, dirty, or where I collect them, are covered with a blackish or grayish layer after being exposed to the elements. It’s when you get them out of the tumbler after the first rough polish that you start to see the hidden beauty underneath.

Here’s part of a batch fresh out of the tumbler! Woo-hoo…some WONDERFUL surprise October presents!  These all were collected in the same 1-square mile area on the Buffalo Gap National Grasslands. Yes…you find this incredible variety of agates and other stones, all in one spot!  Rockhounding nirvana.

A couple of pictures. The first shows what they look like wet, and gives a hint of their final glory.  The second shows them in their dry, current stage.

South Dakota Agates and Jaspers

This is what the agates and jaspers look like wet, after the first tumbling stage. When wet you get a good idea of what they’ll look like when they finish polishing.

South Dakota Agates - Rough phase

Part of a batch of South Dakota agates and jaspers, just out of the first tumbling stage. In this stage, the point is to try to shape them, get off the sharp edges, etc. They don’t even start to show any hint of that glorious, shiny luster they’ll eventually have, but even at this stage…they’re gorgeous!

Beauty in Small Packages

Three months. I’m learning the value of patience with my new rockhounding and tumbling hobby, as I’ve learned the stones I tumble (South Dakota agates) are very hard, and need to be tumbled for a long time to get a good polish. I’ve learned that the process thus takes about 3 months!  I was doing one week for each of the four tumbling steps I do, but wasn’t getting great results until I upped that to three weeks for each step.

I’m pretty thrilled with this latest batch!  I would say this is my first real, high-quality batch that I’ve done.  These are from my small tumbler, and thus, most of these stones are only 1″ to 1 1/2″ inches in length. They’re beautiful even to the naked eye, but I’m finding that the use of my macro lens and a close photo really allows me to see the beauty and detail in these stones.  Here’s a (large!) number of photos of various agates and jaspers from my latest batch.

Bubblegum Agate

This agate had the typical, bumpy, bubbly shape of a bubblegum agate, but when I found it on the Buffalo Gap National Grasslands, it was a dull grayish-black. It took the better part of 4 months worth of tumbling to wear down the outer layer, exposing some of the most beautiful patterns I’ve seen on any of my agates.

South Dakota Agate

I’m calling this one “Crystal Dragon”. Not sure whether you’d call this a prairie, bubblegum, or other agate, but I love the swirling pattern, with the crystal/druzy “neck” on the dragon, and a little pink tongue and eye.

Prairie Agate

A prairie agate, showing a beautiful array of colors. A lot of the more weathered agates on the grasslands have black parts on their exterior. I believe that’s manganese oxide that forms when they’re exposed to the elements (at least some of the blacker agates). Much of the time that black disappears when you tumble, but on this prairie agate, the black was maintained in some of the bands.

South Dakota Agate

Wonderful fine detail that’s not all that noticeable to the naked eye, but is quite evident in a macro photo of this agate.

Prairie Agate

A lot of the bubblegum and prairie agates you find have a very subtle, very fine banding such as this. Very often it’s not noticeable until you tumble.

Bubblegum Agate

A classic bubblegum agate, a little larger than many of the agates on this page. Bubblegum agates really tumble beautifully, as you generally get these beautiful agate “eyes”.

Prairie Agate

Interesting shape on this agate, with a little peak that has it’s own little cap/color pattern.

Prairie Agate

A prairie agate, with a lot of “druzy” (crystally) elements.

Prairie Agate

The biggest agate in this batch is also one of the most gorgeous. This beautiful Prairie Agate has some wonderful banding patterns, and a beautiful range of colors.

Bubblegum agate

Another bubblegum agate with the typical eyes you see when polishing.

South Dakota Agate

I’m not sure what to call this one (help!!). It has a definite linear “grain” pattern, but it’s so unlike all the petrified wood I’ve found that I hesitate to call it that.

Prairie Agate

I love the pattern on this one, with the bold orange streak.

South Dakota Jasper

Jasper? Agate? I dunno. Has a pretty pattern though!

Prairie Agate

The most common prairie agate patterns are jagged, rough striping, but this is also a relatively common type of pattern and color for prairie agates from Buffalo Gap.

Bubblegum Agate

Another polished bubblegum agate

Prairie Agate

A prairie agate with some nice banded patterns

Prairie Agate

I love the contrasting patterns on some of the agates, with very dark sections contrasted by white or very light sections.

Bubblegum Agate

Another bubblegum agate, one that was tumbled awhile and didn’t maintain the “eyes” as much as some of the others.

Fall Sparrows and More…

A wonderful, crisp, sunny fall morning, the perfect morning to sparrowing!! Not too many people get excited about sparrows, but this time of year in South Dakota, there’s such a wonderful variety of species that are moving through. One of my favorite kinds of birding trips…finding a weedy field in the fall, setting up in a quiet spot, and sitting back and enjoying all the sparrow species that are feeding on grass and weed seeds. Some are species we have during the summer as well, such as Savannah and Song Sparrows, but we also get some wonderful migrants such as Harris’s Sparrows and Lincoln’s Sparrows.

The crème de la crème though…Le Conte’s Sparrows. They’re a bird many birders haven’t seen, and even when they’re around, they can sometimes be hard to find as they prefer to hide in dense vegetation. In fall around here though, they are often quite bold.  This morning I saw more Le Conte’s Sparrows than I think I ever have in one day.  One weedy field west of Tea, South Dakota was chock-full of them. They were feeding on weed seeds near a gravel road, and there were times I’d have half a dozen in sight at one time.  A great treat, and I did get some good photos as well.

Photos from this morning:

Le Conte's Sparrow - Ammodramus leconteii

A gorgeous little Le Conte’s Sparrow, basking in the early morning sun along a weedy fenceline.

Lincon's Sparrow - Melospiza lincolnii

Probably my 2nd favorite sparrow, a Lincoln’s Sparrow. They have a touch more color and pattern than many sparrows, and just always look so elegant.

Swamp Sparrow - Melospiza georgiana

A Swamp Sparrow perched among the cattails.

Savannah Sparrow - Passerculus sandwichensis

The most numerous of the sparrow species seen this morning, a Savannah Sparrow.

Song Sparrow - Melospiza melodia

One of our summer breeding residents, there’s a ton of Song Sparrows around right now as well, including many first-year birds.

Sedge Wren - Cistothorus platensis

Seems like Le Conte’s Sparrows and Sedge Wrens often go hand-in-hand when I see them in the fall. The same weedy field with the many Le Conte’s also had several Sedge Wrens.

Franklin's Gull - Franklin's Gull October 7th, 2017 Minnehaha County, South Dakota

Other than sparrows, the most plentiful birds this morning were gulls. The skies were full of gulls, as were the areas near the dump (no surprise) and the bigger water bodies in western Minnehaha County. I didn’t pan through all the massive flocks to look for rarities. Ring-billed Gulls and these guys, Franklin’s Gulls, were present by the thousands.

Ring-billed gull - Larus delawarensis

Thousands of Ring-billed Gulls were around. Here one lounges at the beach at Wall lake.

Curious Red-tailed Hawks

When you encounter a bird in the wild, there’s a standard series of events that occur. Far too often, the encounter ends when the bird flies away as you approach.  Hence the challenge for a bird photographer!! But every once in a while, the quarry seems just as interested as the photographer.  Today was one of those experiences.

I was birding a little bit in western Minnehaha County, west of Sioux Falls. I saw a pair of Red-tailed Hawks sitting on adjacent fence posts on the road in front of me. In these situations, I always have my camera ready when I approach, just on the off change that the bird would actually stay perched and not flush. However, as per usual, the pair both took off well before I got in camera range.

Was was NOT per usual is their behavior after taking flight. Instead of flying off to a distant perch, the pair banked…and turned back towards me as I stood on the side of the road. For the next 3 or four minutes, both of them lazily circled above and around me as I furiously clicked away.  Getting nice flight photos of wild raptors is ALWAYS a welcome opportunity…here are some photos of the pair.

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.

More South Dakota Agates

On Labor Day I again made the long trek to the Buffalo Gap National Grasslands of western South Dakota, a day to look for agates, fossils, petrified wood, and other goodies.  For the first time since we discovered rockhounding this summer, there were actually a number of other people out searching.  You can see how the known agate hunting locations would get picked over.  However, it’s quite similar to a visit to a busy national park like Yellowstone or Yosemite…just get away from the road a bit and you’re likely to have it all to yourself.

Despite several other searchers, I was able to find solitude just by hiking back away from the gravel roads in the area.  There’s no doubt there are more and better finds as you get away from the roads and places people park.  An interesting day, marked by a heavy haze all day from western US forest fires, but also a day filled with agates.  Here are a few agates from the day. Also the latest batch that’s gone through my polishing.  I’ve pretty much got it down now, and can get a real deep shine, but it’s a 2-month process from start to finish!  Always good to finish a batch and see what you get for all your hard work.

Fairburn Agate - South Dakota

This is one I would have loved to have found before it had worn down. I do think this is a legitimate Fairburn agate, but some of the bands are worn away in places. In others, you can really see the fine detail.

Fairburn Agate - South Dakota

The flip side of the same Fairburn. I think I’m going to call this one the “Bacon” agate, given the banding on this side.

Polished South Dakota jaspers and agates

The latest batch to finish in my small tumble polisher. I’m having much better luck now in getting a great shine, simply by 1) taking twice as much time, meaning 2-full weeks in each of the 4 polishing stages, and 2) using distilled water instead of our very hard city water. Just the choice of water has made a huge difference in the shine.

Agatized Syringopora Coral - Fossil

A piece I found earlier this summer that just made it through the polishing process. This is an agatized piece with bits of Syringopora coral fossils throughout. A unique and gorgeous little piece.

Cheating in Photoshop – The “Warm” Eclipse

After viewing a number of eclipse photos on the web, I’ve decided to likewise “cheat”.  When you see the total eclipse live, you’re primarily seeing white light.  Most of the photos you see from the event thus  similarly show a white solar aura around the dark disc of the moon.  However, you also see photos with a very colorful, warm light.

I’m calling it…it’s “cheating”. It’s clearly applying some kind of warming filter.  I don’t do much in the way of photoshop manipulation, but I actually do kind of like the look of the “warm” colored eclipse.  Here’s my shot at doing the same:

Solar eclipse - 2017

My “cheating” version of the eclipse, with a warming filter applied to give it a more “sunny” look (at least how people tend to perceive the color of the sun).

Eclipse Hunting, Rockhounding, and Dinos…Oh My!

What an utterly spectacular weekend with my son.  We had originally planned to head down to my hometown in Nebraska to view the eclipse Monday. A cloudy forecast for much of Nebraska led to a last-second change of plans, and our extended weekend turned into a weekend of SCIENCE!  And may I say, given how the relentless attack on science continues ever since the election of Orange Hitler, a much NEEDED weekend of science.

Our whirlwind sciency tour was planned in haste on Saturday night.  At that time, the surest bet for sunny skies for the eclipse were in eastern Wyoming, a good 7-8 hour drive from home.  We decided to make a weekend of it, stay in the Black Hills over night Sunday (the nearest hotel we could find to the eclipse path…2 hours away!), and do some agate, fossil, and petrified wood exploring on the way.  Sunday we spent some time on Buffalo Gap National Grasslands in the morning, again finding some nice geologic goodies. By Sunday afternoon we’d made it to Hill City, SD, and spent some time in the Black Hills Institute’s Museum. Wonderful place to look at dinosaur fossils, geologic wonders, and other interesting displays.

The highlight of the trip of course was the eclipse on Monday. Anticipating heavy traffic, we left Hill City by 5:30 AM, and made our way to Lusk, Wyoming.  Traffic wasn’t as bad as we thought, so we were there by 8:00 AM. We grabbed supplies, found a quiet gravel road 20 miles SW of Lusk, and waited for the show.

That “quiet” gravel road ended up being not so quiet. Despite the isolation, other eclipse watchers from all over North America paraded by us, searching out pullouts on the side of the road from which to set up camp. By the time the moon first started to creep in front of the sun, our quiet gravel road had people camped out about every 30 yards for as far as the eye can see. People continued to stream down the road, all the way up until the point of totality.

I’ve never seen a total eclipse. My son has never seen a total eclipse. After this experience, I GUARANTEE that we will make plans to see another, as soon as is feasible (likely 2024).  If there’s a more spine-tingling, goosebump-raising, incredible experience to be had, I’m not sure what it is. As the light got every more dim and eerie, anticipation rose, but the moment of totality kind of sneaks up on you. There was more light than I expected, RIGHT up until totality. The awe of seeing the initial “diamond ring” effect, following by complete totality, is beyond words.

I did want to try to photograph the eclipse. I did take several photos at the start of totality, but after several photos, I HAD to put the camera down, and just revel in the moment.  Other than rather incredible traffic trying to get out of Wyoming and back to South Dakota, it was one of the best travel adventures we’ve ever had.

A few shots of the eclipse, before my jaw dropped and the camera was ignored…

Solar eclipse - 2017

Moments before totality, a few seconds of the “diamond ring” effect. I had read about the stages of the eclipse, and knew this was supposed to happen right before totality. Seeing it was still indescribable.

Solar Eclipse - 2017

The eclipse during the 2_ minutes of totality. This has a bit longer exposure than the next shot, gathering more light so you can see more of the corona. Shooting in this fashion though hides the detail you can observe around the edge of the moon’s disc (see next photo).

Solar Eclipse - 2017

Lower exposure reveals what you can see with your own eyes during totality (at least through my camera, or through our binoculars)…solar prominences flaring off the surface of the sun. This was the moment I dropped the camera and just enjoyed the show. With such a short 2+ minute window to enjoy totality, I didn’t want to miss it with my face behind a camera.
