Unusual cold weather has birds struggling in South Dakota

Author: DakotaBirder • Discussion: No Comments

Five very different birds, but five species with something very much in common. The cool, wet spring continues, with rain and wind in the eastern part of South Dakota, and a late May snowstorm in the western part of the state. It had already been an odd migration given the cool temps that don’t want to give way to spring. Until last Friday (May 17th, songbird migration was noticeably slow, with very few warblers around other than Yellow-rumped. But that seemed to have changed last weekend. On Saturday (May 18th) we had a major fall-out of migrants, with warblers of every kind (I had 20 species on Saturday), vireos, flycatchers, and other songbirds appearing seemingly out of thin air. The birding this weekend was positively SPECTACULAR, and there’s no doubt for me it was the best warbler spotting in the 20 years I’ve been birding.

That spectacular birding has come with a price, however. With cool and wet conditions continuing, you can tell birds are struggling. The problem? I just think there aren’t the usual insects out yet for this time of year. Because of that, you’re seeing species with behaviors you normally don’t see. From a bird photography perspective I guess it’s been great, as the birds have been 1) concentrated, with many birds often foraging in select locations out of the wind and rain, and in areas where a few insects might be, and 2) many species have been down lower to the ground than normal.

Here’s a pictorial of five species I’ve encountered in recent days, five species that all appear to be impacted by the cool wet weather.

In the account of the Great Crested Flycatcher on my main webpage, for “behavior” it states that Great Crested Flycatchers are “usually found high in the tree canopy, more often heard than seen”. Normally that’s true. They’re a quite vocal species, and I do hear them more than I actually see them. However, in the last week, I’ve seen a number of them, down low, foraging in areas that seem rather odd for the species. At both Newton Hills State Park and Good Earth State Park, I’ve seen multiple Great-crested Flycatchers foraging on the ground or in low grasslands. Again, my take is that insects are hard to find in the cool wet weather, leading birds like Great Crested Flycatchers to forage in areas they normally would not. Photo is from May 19th at Good Earth State Park.
While birding Newton Hills State Park Sunday, I saw three Scarlet Tanagers, all foraging within a few feet of each other. Seeing Scarlet Tanagers at Newton Hills isn’t news, as it’s one of the best places in the state to find them. To see three foraging together is unusual, however. Seeing all three ON THE GROUND, foraging as if they were Robins, is definitely unusual. It was a cornucopia of color, with a Red-headed Woodpecker low in the nearby sumac, an Indigo bunting down low, and American Robins and Scarlet Tanagers feeding together as if they were the same species. I’ve seen more Scarlet Tanagers this spring than I remember seeing before, but frankly it’s because they’re using habitats and behaviors they normally would not. Photo is from May 19th at Newton Hills State Park.
On Sunday, I spent quite a bit of time at Lake Lakota, a reservoir right next to Newton Hills State Park. Sunday morning was a nasty day…temps in the 30s, foggy, and cloudy with occasional drizzle. Again, from a photographer’s perspective it certainly played to my advantage, as birds were heavily concentrated along the lake shores of Lake Lakota. That’s been a common theme in the last week, with insect eating birds often found very near water sources. Given their behavior and concentration, presumably it’s because these insect-eating birds are going where the food is, and with the cold weather, it seems insects associated with water bodies are some of the few that are around. There have been a few times over the last 20 years where on a cold May day, I’ve found heavy concentrations of all kinds of swallow species on the ground, and Sunday was one of those days. Sitting on the beach at Lake Lakota were Tree Swallows, Barn Swallows, Cliff Swallows, Northern Rough-winged Swallows, and Bank Swallows. At any one time, it appeared that about two-thirds of the birds were perched on the beach, with a few low in nearby shrubs and trees. The other third were swooping over the lake itself, extremely close to the water’s surface as they searched for food. Those on the beach would occasionally move, but not in typical swallow fashion. Several appeared to sometimes be almost walking around looking for food, VERY strange for species that collect their insect prey in flight. It wasn’t just swallows, as other species were also concentrated on the beach, including more Baltimore Orioles and Orchard Orioles than I’ve ever seen in one location before. Given that they were seemingly struggling, I didn’t want to get too close for photos, so the photo above is of a Tree Swallow from a similar situation several years ago, on a very cold morning at Lake Thompson in South Dakota.
Speaking of shorelines along water bodies…while most warbler species were pretty much absent in the area until Saturday, that definitely wasn’t the case with Yellow-rumped Warblers. They have been THICK, but often in areas you don’t associate with warblers. While driving north of Wall Lake in western Minnehaha County last week, I saw many birds perched along a barbed wire fence, occasionally flying out to “flycatch”, capturing insects in mid-air. It was an area with a couple of shallow wetlands, areas that must have hatched some mosquitos or other flying insects despite the cool wet weather. It was an area with nary a tree in sight, yet as I got closer I saw what they were…ALL Yellow-rumped Warblers, in big numbers, hanging out here in a completely open landscape and making do with what bugs they could find. The situation was similar one day when I was looking for shorebirds at Weisensee Slough in western Minnehaha County. Weisensee is the last place I’d think of going to look for warblers, given as it’s a very large wetland/water body, with just no woodland patches on the accessible part along the road. That was a very windy day, shorebirds were almost completely absent (another blog post about shorebird migration perhaps), and with the chop on the water, it was difficult to see many birds out on the lake. Yet as I approached the ONE location along the road with a few very small willow trees, I saw a heavy concentration of Yellow-rumped Warblers, perched on the shoreline itself or low in the trees on the lee side of the wind, trying to capture insects. The photo above is one of those Yellow-rumped Warblers from Weisensee.
On Facebook I’ve been seeing many photos people have posted of their orange and jelly feeders, with big concentrations of Orioles. On the east side of the state, that means Baltimore and Orchard Orioles, while Bullock’s Orioles are also thrown into the mix in western South Dakota. that’s certainly been the case at my feeders as well, as I typically have to fill my two jelly cups every morning. The same thing happened during a cold snap last May, where very hungry, insect-starved Orioles showed up at my feeders in force…also the first time Orchard Orioles joined the Baltimore Orioles in our suburban neighborhood.

There be BIRDS at the end of the rainbow!!

End of the Rainbow - Lincoln County, South Dakota

The age old question of what’s at the end of the rainbow has been answered. It’s this family farm in Lincoln County, South Dakota

I went birding last night, on a weird weather day in South Dakota.  It was cloudy, then sunny, then cloudy again as a brief thunderstorm would roll through, then sunny again…wash, rinse, repeat.  It was actually a bit of a crisp day with temps hanging around 55 degrees, but even so, there were a couple of the little thunderstorms that put out quite a bit of pea-size hail.  It was such a strange evening given that it was absolutely pouring rain at times, yet the sun was shining.

Despite the rain, the birding was quite wonderful (as it generally is in South Dakota in May!!) The best birding for the day was when I was hanging out by a large wetland, one that had swollen with the recent rains to cover much of the surrounding farmland in a shallow sheet of water. Shorebirds were certainly loving it, as were a beautiful little group of Black Terns.  Forster’s Terns were much more numerous, hanging out on fence posts during the rain spells, dipping and diving over the water whenever the rain would stop. It was actually quite peaceful, watching the intermittent downpours, then seeing the birds jump back to life again when the sun would break out. It’s tough being a bird though when the hail starts!  They seemed to do OK with the little pea-size hail that fell at one point. but they weren’t very happy about it!  Shorebirds tended to crouch low during the hail, as did the terns on the posts, but otherwise, they just stayed still and endured.

Although the birding was quite good, the best moment of the night occurred after one of the little thunderstorms. With small scattered storms separated by wide bands of open sky, the sun was frequently pushing through, even during some of the rainy moments.  A beautiful and extremely long-lasting rainbow lit up the eastern sky and was visible for over half an hour as the little thunderstorm continued slowly pushing on to the south and east.  It was a full rainbow, with a partial double rainbow above it, but without my wide-angle lens along (hey, I’m a birder, I rarely use it anyway), I wasn’t able to get a photo of the whole thing. Instead, with my 400mm birding lens on, I decided to shoot what was at the end of the rainbow…this family farm! I’ve certainly never tried shooting a rainbow with a telephone lens, but I think the effect was quite beautiful.

The weather is supposed to be beautiful again this weekend, so hopefully within the next day or two I’ll have some more birding photos and stories to share…

Forster's Tern - Sterna forsteri

A Forster’s Tern perched on a little metal fence pole. This was just prior to the arrival of a little rain band that produced pea-sized hail. Fortunately, the birds seem to cope with the small hail quite well.
