South Dakota Winter – Best…photo…day…ever!!

Since I’m still not allowed to go back to work, I spent yet another day birding in the central part of the state. It was a day with lower overall numbers of raptors. I saw far fewer Rough-legged Hawks than normal. I didn’t see any Gyrfalcons, Snowy Owls, Short-eared Owls…some of the “goodies” you often find.  But birding and photography is funny! I’ve had awesome birding days where I got very few photos. Today was the opposite…not huge numbers of birds, but some really wonderful photo opportunities.  Here’s some pics from the day with a little info for each:

Prairie Falcon - Falco mexicanus

While it wasn’t a banner day for many of the “usuals”, I saw more Prairie Falcons (7) than I remember seeing in one day. “Seeing” and “photographing” are two very different things, however. Prairie Falcons are about THE shyest, most skittery raptor I know of. Today however I got a real treat. While birding in Jones County, I saw a falcon on a telephone pole. As I always do, I first stopped a long distance off, grabbed the binoculars, and tried to identify it. Definite Prairie Falcon. I then started to approach, and as ALWAYS happens with Prairie Falcons…it flew off LONG before I got into camera range.  But then something funny happened…it turned around. Still not expecting much, I got out of the pickup and grabbed my camera. But he came closer…and closer…and closer, and I soon realized he was going to fly RIGHT over my head! I couldn’t have asked for a better setup…bird approaching on a clear day, sun in the perfect position to get nice lighting on him, and he was CLOSE…closer than I think I’ve ever been to a Prairie Falcon. He passed right overhead, and then proceeded to…well…check out the next photo.

Prairie Falcon and Lapland Longspurs

As the Prairie Falcon flew towards me and over the field behind me, there was an eruption of Lapland Longspurs, Horned Larks, and quite a few Snow Buntings. THAT got the Prairie Falcon’s attention. Instead of continuing to fly past and away from me, he again turned, and started to interact with the mixed flock of birds. At points it was almost like he was herding them! He never came as close as he did for the original overpass, but he offered some more really nice photo opportunities, and with several shots I captured some of his potential prey in the background. Despite scaring the flock of little birds, I never did see him actually make a strong move towards one. After a little while he seemed to get bored, and went back to a nearby telephone pole.

Bald Eagle - Haliaeetus leucocephalus

I remember when I first started birding, and came across my first bald eagle. It was the winter of 1999/2000, and I thought it was the most magical experience I’d ever had! In the 20 years since then, Bald Eagles have become, well…downright COMMON! When I bird the central part of the state in winter, I always run across them. There are several nest locations in the area, and I always KNOW there will be Bald Eagles in a few select spots. One such spot is near Presho, and when I drove past it, sure enough…there were 4 Bald Eagles in a small grove of trees, 3 adults and one sub-adult. Given how often I’ve seen eagles there, I’m sure they’re the same ones, or the same family. As such, perhaps today they gave me a pass and stuck around and let me photograph them! Three of the birds were hidden within the branches or were towards the back of the grove, but one bold individual adult just stared at me from his perch, wondering what I was up to. I watched him for quite some time, before he did what many raptors do right before they’re about to take flight…he pooped and positioned himself to fly off. Those can be truly wonderful moments for photography, with some truly angelic poses. This is now probably one of my favorite Bald Eagle photos that I’ve taken (and I will add it to the hundreds of other Bald Eagle photos I already have!).

Ferruginous Hawk - Buteo regalis

Not only did I have a banner day for Prairie Falcons, but I also saw more Ferruginous Hawks than I normally do…5. 4 of them were in Jones County, and the reason was obvious…Prairie Dogs. Without exception, all 5 Ferruginous Hawks on the day were in and around prairie dog towns. I do have a few photos of other color morphs, but today all were the same light color morph (the most common one). Some, like this bird, are SO snowy white on their undersides with barely a hint of marking, that I sometimes mistake them for Snowy Owls as I approach from a distance! One of my favorite bird species, hands down, and there’s a bonus with Ferruginous Hawks…they are MUCH more cooperative for bird photographers than nearly any other raptor species on the grasslands!

Ferruginous Hawk - Buteo regalis

My longest birding lens, and the lens with which I’ve shot at least 95% of my photos with over the last 15 years, is a Canon 400mm 5.6L. Yes, it’s now 15 years old. But it has always been one SHARP lens, with some incredible detail when you get a bird filling the frame of a photo. The downside…most birders use a 500mm or 600mm, WITH a tele-extender. In short…they have a LOT more “reach” than I have! Because of that I’ve 1) learned how to overcome using a somewhat shorter lens, and 2) learned to accept I’m going to miss some shots where more length is required. However, that latter point is all bad. While I like photos with the birds filling the frame, I also like photos showing the bird interacting with its environment. Here, I came across another Ferruginous Hawk on a prairie dog town. I was nowhere near close enough to get a frame-filling photo, so instead worked on capturing his behavior as he “worked” the prairie dog town, alternating between sitting on the ground or a fence post, and flying through the prairie dog town looking for prey. I never did see him capture anything but it was fun to watch the behavior and try to catch it in a photo.

Golden Eagle - Aquila chrysaetos

Speaking of “environment” photos…here’s a pair of Golden Eagles at the “usual” hangout. By “usual” I should say nearly ALWAYS. This was taken south of Presho, in one of my favorite birding locations. This fallen down structure nearly always…ALWAYS…has a golden eagle sitting on it! Well, during winter and in the morning, that is. When I make trips to this area, I usually try to make it to the Presho area by dawn, and this is one of the first areas I look for raptors. And I swear, 95% of the time when I drive past this fallen-down structure, there’s a golden eagle sitting on it. Today there were two eagles! This kind of winter-range site fidelity is pretty cool, and it’s not just these Golden Eagles. About 5 miles northwest of here, west of Presho, is a farmstead where I ALWAYS find a Northern Shrike in winter. ALWAYS. Has to be the same one, right? Again, not a frame filler of a photo, but I love showing these birds at their favorite hangout.

Rough-legged Hawk - Buteo lagopus

Ok, this one is cheating a bit. This one isn’t from Wednesday, January 9th, it’s from Friday, January 4th. Rough-legged Hawks aren’t as numerous this winter as they can be many winters, but there still are always at least a few hanging around. Here’s one taking flight in the early morning sunlight.

 

Representation of Diversity – Or not

I never relay where I work on my blog. Or on social media. Why do I do that? Because anything I post is my opinion alone, and doesn’t relate in any official capacity to my work. All I will say is that right now I am BORED OUT OF MY FREAKING MIND, since I have been unable to report to work for the last 3 weeks. And as time passes, that boredom is gradually transforming to being PISSED OFF.  PISSED OFF at our elected officials who can’t do their jobs, and allow others to do theirs.

So instead of working on a journal paper I REALLY need to finish, instead of creating graphics to support that paper…I made this graphic. Showing how complete unrepresentative our political representatives are, particularly if you’re in the GOP. 88 PERCENT of the GOP House and Senate are white males. Mostly RICH white males, who’s life experience can’t possibly relate to the hardship they’re causing millions of Americans right now.

116th US Congress - Demographics

Demographics of the 116th US Congress. If you’re a rich, white male, you’re WELL represented. If you’re primary mission life is the acquisition of wealth, you’re well represented. If you’re a minority? A woman? Well, you’re kind of screwed.

ID Challenge (for me!) – Glaucous vs. Iceland Gull

OK, I admit it. I often don’t have the patience to scan through large flocks of gulls to find the “oddball”, the one that ISN’T the seemingly ever-present Ring-billed Gull (here in South Dakota). Sometimes, however, you see something that’s clearly so different than you can’t help but notice. That was the case yesterday near Pierre, South Dakota, when I saw a large, nearly all white gull sitting on the ice.  My first thought when seeing the bird from a distance…Iceland Gull, since recent bird reports had frequently mentioned an Iceland Gull being seen in the area. At first glance, that seemed to “fit”.  However, as one who isn’t well-versed in the dark art (I’m think of you Ricky Olson!!) of multi-age gull discrimination…I wasn’t sure. It wasn’t until I got home, downloaded the photos, and did some sleuthing  where I think I can safely call this an immature (probably 2nd winter), quite pale Glaucous Gull. Why?

Immature Glaucous and Iceland Gulls both share some characteristics that were evident in this bird. 1) Pale overall, including pale wingtips without markings. 2) two-toned bill. 3) pink legs.  However, when looking at Sibley’s and online resources, it’s clear the bird has characteristics of a Glaucous Gull.  First…the bird’s size.  There were a handful of Ring-billed Gulls around, and this bird was clearly larger. Much larger. Iceland Gulls are larger than Ring-billeds, but Glaucous Gulls are MUCH larger. With the distance between the Ring-billed Gulls and this gull, it was a bit difficult to judge, but it really did look a much, much larger bird than the Ring-billed Gulls.

Secondly…the head. From this excellent site (South Dublin Birds), it’s noted Glaucous Gulls have a large, flat-topped head, while Iceland Gulls have a more delicate looking, rounded head. This bird clearly has the head shape of a Glaucous. Also…that site is the only one I found that notes a “tertial step”…a clear angle where the tertial feathers on wings meet the primaries when the wing is folded as in the first photo below. Here, you definitely see a clear “step” down where the tertials meet the primaries. Finally, the bill. Young Glaucous and Iceland Gulls both may share a two-toned bill such as this, but the Glaucous Gull has a heavy, longer bill, with parallel top and bottom edges. The Iceland Gull has a much more delicate and smaller looking bill.   The bill on this bird is quite large and shaped as a Glaucous.

So my final call…a first- or second-winter (probably second), very pale Glaucous Gull. Darker juveniles often have a lot of brownish speckling. This bird has a very small amount of that, primarily near the tail. Given that Glaucous Gulls gradually lose that speckling and it’s mostly gone by the third year, my guess is its a second-year bird that’s lost most of the speckling.  Third winter birds generally already have the pale gray mantle of an adult Glaucous Gull. This bird clearly doesn’t have that yet, so it can’t be a 3rd year or adult bird.

In short…the bird looks very similar to the Sibley drawing of a 2nd-winter Glaucous Gull (Page 220 of my Sibley’s guide!).

There…that wasn’t so painful! And it was kind of an interesting challenge to ID. Perhaps next time I come across a flock of gulls, I’ll pay a little more attention and do some similar sleuthing!

Glaucous Gull - Larus hyperboreus

A large, pale gull found near Pierre, South Dakota. Given that others had reported an Iceland Gull in the area, that was must first thought. But upon getting home and seeing the photos in detail, I’m pretty sure now this is a very pale, immature Glaucous Gull. Reasons…1) The heavy two-toned till, with top and bottom roughly parallel. Immature Iceland Gulls also can have a two-toned bill like this, but it’s smaller and more delicate. 2) Head shape…large, flat topped. Iceland Gulls heads are more rounded and smaller looking. 3) “Tertial Step” – an ID characteristic where there’s a distinct “step” where the tertial feathers meet the primaries (unlike Iceland).

Glaucous Gull - Larus hyperboreus

With wings spread, you can see the complete lack of markings on the wings. However, the pale wings, pink legs, and brownish mottling (VERY pale and not widespread on this bird) can be found on both Iceland and Glaucous Gull.

Glaucous Gull - Larus hyperboreus

Another photo of the bird taking flight, showing the unmarked wings (again, characteristic of both Iceland and Glaucous).
