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.

A “birdy” kind o’ day…

Ovenbird - Seiurus aurocapilla

Ovenbird, one of many I heard and saw today at Newton Hills State Park.

The weather wasn’t great this morning.  Cool, overcast, and drizzling every once in a while.  The options for such a Friday in May…go to work, or take the day off despite the weather and go birding all day.

Of course option B was chosen.  May is such an incredible time to bird here, with all the migrants moving through and the summer songbirds arriving.  I spent most of the day at Newton Hills State Park, a gem of a place in Lincoln County, South Dakota.  It’s got wonderful forest habitat reminiscent of forests of the Eastern U.S., right here on the (mostly) plains of South Dakota.  With an “eastern forest” comes “eastern birds”.  Newton Hills is often one of the very few places where you can find some species of forest birds in the state.

At this time of year, the summer breeding residents are arriving and singing their hearts out.  One of my favorite species was one of the first birds I heard when I arrived this morning, an Ovenbird singing his little heart out from the top of a fence post.  Newton Hills is the most reliable spot I know of to find these guys both in the spring, and during the summer breeding season.  I saw several Indigo Buntings flitting through the big Burr Oak trees, providing momentary glimpses of a shocking brilliant blue that you just don’t expect to see flitting through the forest canopy.  Rose-breasted Grosbeaks were singing everywhere, as were Eastern Towhees.  Two of the most numerous summer breeders in parts of the park were also two of the loudest and most obvious birds today, with Yellow Warblers singing and chasing each other all over the place, and the ever-present (in summer anyway!) House Wrens found in practically every corner of the park.

Black-and-white Warbler - Mniotilta varia

One of the things I’m learning to appreciate is the unseen, yet heard bird.  Ok, yeah, may seem obvious, but for a guy who has focused on bird photography for so long, seeing has always trumped hearing for me.  There were several species that I heard today, but only got a very brief glimpse of or didn’t see at all.  I hear Wood Thrush in multiple spots, with their beautiful, metallic-sounding (to me) songs.  I desperately was trying to get a photo of a Scarlet Tanager I heard, but he stayed in the treetops and never even gave me a glimpse. One singing bird I REALLY was trying to track down was what sounded very much like a Kentucky Warbler.  I heard it singing at some distance, but when I walked towards the area it stopped singing and I never found it.  I’ve never seen a Kentucky Warbler, hence my excitement at hearing the bird.  I don’t know the song of one well enough for me to conclusively say that’s what it was, even though it sure sounded like a Kentucky Warbler when I got back to my car and compared to the song of one on my iPhone.

Alas, a rarity and a lifer that eluded me.  It really wasn’t a terrific day for any unusual birds, but there certainly was a really nice variety of migrants and arriving breeding birds. The birds I get the most excited for this time of year are the warblers, but other than those mentioned above, the only other species I saw today were Black-and-White, Orange-crowned, Yellow-rumped, and Common Yellowthroats.  Warblers are so unpredictable here though, with birds seemingly “dripping off the trees” on some May days, and seemingly absent on others.

A great day overall!  One puzzling thing though was how it was so “birdy” at Newton Hills, but so completely dead at another spot I visited. I haven’t been to Union Grove State Park very much, but in many ways it’s very similar to Newton Hills, with a lot of uncharacteristic (for South Dakota) eastern forest land.  As loud and boisterous as the birds were at Newton Hills, I was immediately struck at how quiet it was at Union Grove.  I kept listening for birds, trying to find a “birdy” spot to get out and walk, but I was met by complete silence.  After half an hour I’d driven all the roads in the small park, and the only birds of ANY kind I saw were a pair of Turkey Vultures, a Crow, and a Blue Jay.   The only birds I heard but didn’t see were a Red-bellied Woodpecker and a Chipping Sparrow on the way out.  Weird…not even a Robin, when they were all over the place at Newton Hills.

Orange-crowned Warbler - Vermivora celata

Ok, somebody tell me…have you EVER seen an actual “orange crown” on an “Orange-crowned Warbler”?

Despite the quiet at Union Grove, despite the rather gloomy weather to start the day, it ended up being a very nice day of birding. There were about a dozen “first-of-year” birds for me, which brings me up to around 160 species for the year so far, within South Dakota.  Not bad, considering we’re a frozen wasteland for 6 months of the year, and there’s not much for quantity or variety of birds during that time!
