South Dakota “Big Year” and Other 2019 Highlights

White-eyed Vireo - Vireo griseus

I never was really a “lister” as a birder until eBird came along. eBird makes it so ridiculously easy to track your sightings, and the tools they have to categorize your sightings by date…geography…comparison to other birders…certainly bring out the competitive side that many birders seem to have! However, even after I started using eBird, I never really set any yearly goals, such as a “big year”. The closest I ever came was a number of years ago when a birding friend at work and I had a very low-key competition to see who could see the most birds in South Dakota during the year.

I ended up at 212 that year, a very similar number to my friend. I’ve gotten close to that a few times since according to eBird, but never really had a “South Dakota Big Year” as a driving goal for my birding in a year. Going into this year though, my birding time had been declining and I seemed to be losing some interest. I thought setting a goal to break my yearly South Dakota record might re spark some of that enthusiasm.

It did!! I started early in January this year…a tough time to start building a bird list in South Dakota! Particularly in a very cold, snowy winter, getting up to just 100 birds by mid-April was doing very well! When spring migration rolled around, I spent more time birding than I have in years. As the year progressed, I never made it to spots like far northwestern South Dakota to tick off species like Baird’s Sparrow, but I made my usual trips to the central part of the state, the Missouri River dams, and a very rare (for me) dedicated birding trip to the Black Hills.

By mid-December, I’d easily passed my highest yearly total, with 248 species. With travel and family commitments in the latter half of the month, I wasn’t expecting to get any more, but when a White-winged Crossbill was seen in Sioux Falls the week before Christmas, I did make the short trip and checked of #249. One short of a nice round number!! I told my wife (notably NOT a birder, and not too invested in the number chase!) that the only way I’d get to 250 is if something unexpected showed up in the yard. Well, on Christmas Day I got a nice surprise present, when a Sharp-shinned Hawk nailed a House Sparrow in mid-flight in the back yard, and then proceeded to consume it right outside our sunroom window. Not that rare of a species around here in winter, but when entering the sighting into eBird, I was surprised that I hadn’t recorded that species yet in 2019, and it was indeed #250!

Sharp-shinned Hawk - Accipiter striatus
A Sharp-shinned Hawk catching a House Sparrow in our back yard on Christmas Day. Species #250 for the year, and a photo that’s instantly one of my favorites.

250 species for the year…a nice number to end with! Not as nice a number as the rather miraculous 303 found by Kenny Miller this year (WOW…considering we’ve only had about 420 species total that have ever been seen in the state), but it was enough for me to end up tied for 6th in the state this year. Something I never thought I’d do as a birder…comparing my year in such a manner…but again, that’s what the wonderful eBird tools do to even a pretty non-competitive birder!!

Sprinkled in those #250 are some definite highlights for the year…new life birds (7 new birds never sighted before anywhere), or new life birds for the state of South Dakota (an additional 9 new South Dakota lifers). Here are some of those 2019 highlights….including some from a major 2019 (and lifetime) birding highlight that’s definitely NOT South Dakota focused.

In mid-April, I had a conference in Pierre for work. With the conference starting at noon, I left home long before dawn, hoping to get a few hours of birding in before the conference. As I was driving near the Missouri River southeast of Pierre, I saw a number of American White Pelicans along flooded areas along the river, so when I saw a large, white bird with black wing tips flying parallel to the road in front of me, I immediately dismissed it as a pelican. This was no pelican! My jaw dropped as I got closer and saw that it was a lone Whooping Crane!! MAJOR frustration as I quickly grabbed the camera and tried to grab a few frames, but the bird disappeared over a ridge and I thought I’d never get a chance to document the sighting. However, when I found a tiny side road, I was able to relocate the bird foraging in a corn field. For the next hour I watched the bird, getting some long distance shots as it foraged, and a few frames in flight when it left the corn field and returned to forage in a wetland area along the river. My first ever Whooping Crane sighting, and definitely a highlight for my 2019 South Dakota bird list!
Henslow's Sparrow - Ammodramus henslowii
When you’re trying for a South Dakota “Big Year”, spring migration is…everything! There are so many migrant bird species that move through the state, and you have a narrow window in which to spot them. By mid- to late-May, the spring migration was…disappointing! It was very cold yet, and very wet. Warblers are a huge draw for me when I bird in the spring, yet by May 19th, I’d only seen a handful of warbler species. On that day, the South Dakota Ornithologist Union was holding it’s spring meeting in Brandon, and a miserable forecast (stormy cool weather) didn’t seem to bode well for birding! It ended up being a truly magical day, however, with over 20 warbler species seen by birders in the Sioux Falls area that day. I myself ended up with 20 different warbler species that day, including several that you don’t see every year. The highlight of the day though was a lifer, a Henslow’s Sparrow that other birders found foraging in a grassy field on the south side of Newton Hills State Park.
American Three-toed Woodpecker - Picoides dorsalis
As a family we typically go the Black Hills once or twice a year. It’s a 6 hour drive (South Dakota is a big state!), so it’s not somewhere I get to bird a lot, and when with the family, my birding time is generally limited. However, in July I took a dedicated 3-day birding trip to the Hills, hoping to pick up a number of South Dakota species I hadn’t recorded in the state before. It was a great trip…I ended up adding 10 new South Dakota species, more than half of my new 2019 South Dakota total. It was also rather frustrating! I have yet to see a Bullock’s Oriole in the state! They’re common out there! I have yet to see a Black-headed Grosbeak! Also common out there! But I did pick up several South Dakota lifers, and one that was an all-time lifer, when this American Three-toed Woodpecker foraged on spruce trees very close to me.
Not a South Dakota lifer, but one I didn’t have on my yearly list until a VERY unexpected lone Rock Wren showed up at Good Earth State Park along the Iowa/South Dakota border. You can count on one hand the number of Rock Wrens recorded in eBird within 200 miles of this location! A good sighting, and a nice addition without which I wouldn’t have gotten to 250.
Magnolia Warbler - Setophaga magnolia
A Magnolia Warbler from that magical weekend of May 19th. One of 20 different warbler species I recorded that day.
Eastern Rosella - Platycercus eximius
Definitely not a South Dakota bird! But a definite 2019 highlight for birding…a 3-week vacation with the family in Australia! Not a birding trip, but of course I was able to get a lot of life birds on that trip, including some incredibly colored species such as this Eastern Rosella.
Southern Cassowary - Casuarius casuarius
A moment I’ll never forget, when a freakin’ DINOSAUR stepped out of the rainforest right in front of us. A massive Southern Cassowary, from near Cairns, Australia.
Rainbow Lorikeet - Trichoglossus moluccanus
A pretty common sight in many areas where we went in Australia, a Rainbow Lorikeet. Given how they’ve adapted to city life and human landscaping, they’re actually considered a bit of a pest in many areas, but OH what a beautiful pest.
Galah - Eolophus roseicapilla
One of my favorites from Australia, a Galah. SO entertaining and social…just incredible fun to watch as they interact with each other and their environment.
Blue-winged Kookaburra - Dacelo leachii
Blue-winged Kookaburra from near Port Douglas. A BIG, chunk bird, these are the less common of two Kookaburra species we saw. The much more widely spread Laughing Kookaburra was a species we found in all the locations we visited in eastern Australia.

Mesmerizing Migration Map

Cornell - Migration Map

The mesmerizing migration map, from Cornell University. Each dot represents the typical migration movement and timing for an individual species.

I’m not nearly clever enough for such use of alliteration in a post title…this is straight from the source!  But it’s such a great name and title for the material, I had to use it.  Using eBird data that provides millions of bird sightings submitted by everyday citizens, Cornell University put together animated maps that depict bird migrations in the Western Hemisphere (click to see the animated maps).  118 species are represented, showing typical migration routes over the course of a year.

It’s fascinating to view.  The animation starts at the start of a year, and there’s not much movement at first, as birds are settled into their winter range.  A few oddballs start migrating quite early, but by March there’s widespread movement which crescendos in April and May before most birds are in their summer ranges.  Some species already start moving back south during the month of June, and by September there’s a mass south-bound flux of birds.

The long established monitoring programs of the Breeding Bird Survey and Christmas Bird Count are great, providing relatively consistent observations of birds for well established routes and locations over several decades. This animated map, however, helps to show the power of eBird.  As someone who has used eBird both as a birder for the recording of my sightings, and as a scientist for the use of the data in bird species distribution modeling, I’m well aware of some of the difficulties with the data.  Given that anyone can enter sightings, there’s no systematic sampling design, there’s definite bias in sightings towards both heavily populated areas and for more “charismatic” species, and there are issues with reliability of sightings with bird ID skills ranging from novice to expert.  But given that eBird data aren’t limited to a specific season or geography, they offer an opportunity that BBS and CBC cannot…the ability to track bird movement, and also track how those movements change in the face of climate change or other stress factors.

Very cool map…it’s very interesting to try and follow one dot over the course of the year!  Only thing I wish it had were some kind of label (or clickable dots) so you knew what species each dot represents.

South Dakota Big Year (Kind of…)

Sora - Porzana Carolina

Sora, one that’s not hard to “count” around here if you go by sound. It’s another matter to see one, much less get a good photo. This is from late April.

I’ve never been a huge “lister”, at least in the formal sense. I know what birds I’ve seen, but I really haven’t ever kept a written list anywhere. Photos? Yeah, I definitely know how many bird species I have photos of. I keep a spreadsheet to organize my photos, with species, date, and location. I have photos for 415 species, all in North America (I haven’t traveled outside of North America during my time birding).

For species I’ve actually seen? I have a rough guess of around 480, just based on the number of of species photos I have. The problem is that I’ve never kept track of species that I’ve seen, but not photographed! Hooded Warbler? Check! Baikal Teal? Check! Even something as common in South Dakota as a Prairie Chicken? Check! I’ve seen them all, but have no photos.

If eBird would have existed when I started birding 15 years ago, I would definitely have an exact count. I’m not just talking my lifetime bird list, I’m talking my “South Dakota List”, my “Minnehaha County List”, my “2008 List”, etc. It’s a wonderful tool for not only contributing to ornithology studies, but also for listing. Since I really started using eBird a couple of years ago, I’ve entered 419 species, including 277 in South Dakota.

One of the interesting aspects of eBird is that you can get your “ranking”, in comparison to other birders in your area. I can see who has the most sightings in South Dakota, in my county, in the U.S. as a whole, or even who has the most “yard birds” in their life. It’s pure genius to me that Cornell includes these features in eBird. Given how (annoyingly sometimes!) competitive birders can be, seeing how you rank against others in your area is a good way to spur more eBird sightings!

This year I decided I would track how many species I see in South Dakota, for several reasons. First, I’ve never done it, and was curious how many the number might be in one year. Secondly, if you’ve birded for a while, seeing your 1,987th Common Nighthawk may not be that exciting, but I admit it IS satisfying to mentally and physically cross it off your list for the year, the first time you see one.

Ovenbird - Seiurus aurocapilla

A species that screams SPRING to me, an Ovenbird. So nice to hear them singing when they arrive in May. Another you normally hear before you see it. Ovenbird was around bird #160 for the year.

It’s May 26th, and the count for the year is (drumroll please…) 193 species seen in South Dakota. That’s many more than I thought I’d have seen by this date.  If you include every rarity ever seen in South Dakota, even if there’s only one recorded instance, there are about 435 “South Dakota species”.  Recording 193 of them in less than 5 months seems pretty good to me, particularly since I haven’t traveled at all in the western part of the state, where many species can be found that can’t be found in the eastern half of South Dakota.  It’s also good from the standpoint that I haven’t seen much in the way of “mega rarities”, which means I’ve seen a good majority of the species you’d expect to see over the course of the year.

The downside?  Well, if you’d have asked me on January 1st whether I’d take 193 species by May 26th, I’d have definitely said yes!  However, 193 puts me in a mere SEVENTH place in South Dakota right now!  SEVENTH!!! The highest totals right now are around 220 species.  Does that bother me? I admit it kind of does!  I have REALLY birded much more this spring than in the past several years, and thought I was doing pretty good!  Evidently there are even kookier bird nuts out there than me!!

CURSE YOU eBIRD, for bringing to light my birding inadequacies!!! If it weren’t for eBird, I’d be quite merry with my 193 total!!

Photographing a non-existent bird

Photo of Blue-winged Warbler - Vermivora cyanoptera

A Blue-winged Warbler seen at Newton Hills State Park in South Dakota. Most sources would consider it to be very rare for the area, or an out-of-range vagrant. Thanks to “citizen scientists”, I think our understanding of bird distributions is going to be much improved in the coming years.

I visited Newton Hills State Park this week.  It’s a wonderful place to bird, and rarely fails to produce some interesting birds, particularly given that its an oasis of forest in a vast plain of corn and soybeans.  While walking along a path I heard what is now a familiar song, a buzzy quiet song that sometimes sounds like half insect, half bird.  Soon the source the song popped up on the top of a nearby cedar…a Blue-winged Warbler.  I was able to take quite a few decent photos of him before I moved on to find other quarry.

What’s always interesting about that spot in Newton Hills, and that species, is that they’re generally assumed NOT to be there.  Oh, among local birders, that particular spot is well known as “the”  place to find a Blue-winged Warbler in South Dakota.  However, if you look at field guides or other sources of bird information that provide range maps, southeastern South Dakota is either on the very extreme edge of the Blue-winged Warbler’s range, or it’s outside their normal breeding range.  Despite that, most years you can find a couple of pairs of Blue-winged Warblers breeding in this corner of Newton Hills State Park.

As always, I recorded the Blue-winged Warbler sighting in eBird, along with all the other birds I saw on that day.  If you’re not an eBird user, when you report a “rare” or unusual bird, the software flags it, and makes you enter a bit a detail about the sighting.  To further verify the identification, you can upload a photo that you may have taken of the bird.  EBird flagged Blue-winged Warbler as rare and unusual for the area, so I added a blurb about the very clear sighting, and also later uploaded a photo to accompany the report.

I’m in the habit now of entering eBird sightings most of the time when I go birding, but I’m still surprised sometimes when eBird flags a sighting as rare and unusual.  It does make you realize how incomplete our understanding is for even the most basic of characteristics of a given bird species…where they can be found.  There have been a number of times where I’ve casually entered a species in eBird, and have been surprised when eBird has flagged it as rare for the area.  Many times, it’s a species I’ve found in that area quite consistently.

I’ve brought up eBird here before, but as I photographed and reported what many sources consider to be a “non-existent” species for this part of the country, it does make you realize the power of “citizen science” and what a massive database such as eBird can do to improve our understanding of bird species distributions, migration timing, etc.

Predicting that next invasion of winter finches

Common Redpoll - Acanthis flammea

A Common Redpoll, one of several “northern finch” species that sporadically invade the conterminous U.S. With this study, perhaps those irruptions could be predicted in the future.

It was 2 winters ago that we had an incredible redpoll invasion.  I’d never even had one in my yard before, and we’d lived in South Dakota for 20 years.  However, in the winter of 2013/2014, we had Common Redpolls around for several months.  A real thrill when one, and then another, Hoary Redpoll showed up at my feeders and stayed for a couple of weeks.

Such events are always a surprise, and it’s not just Redpolls.  Both Red and White-winged Crossbills are equally unpredictable winter invaders across the U.S., as are Pine Siskins and Evening Grosbeaks.  It was generally understood that large movements southward in the winter were due to poor seed crops for pines and spruces further north.  A new study from the University of Utah attempts to explain the winter invasions, based on climatic variables. First, the study finds that favorable climate patterns tend to shift across the continent. When one region is favorable to seed production, other parts of the continent are more likely to have unfavorable conditions for seed production, resulting in periodic movements in birds as they key in on areas with the most food resources.

The other climate finding is that it may be possible to predict irruptions to south up to two years in advance!  Seed production itself tends to be correlated with favorable conditions 2 or 3 years PRIOR to the actual growing season.  So, for example, if 2015 has unfavorable climate conditions in much of Canada, it may mean reduced seed production in 2017, resulting an increased likelihood of a southward irruption of northern finches. One of the things I love about birding is the total unpredictability, as you never know what you may see when you head out, but it would be cool to be able to anticipate a great winter finch season.

One final aspect of the work I like…they relied very heavily on eBird data.  A GREAT resource, but one that really isn’t being used for research nearly as much as other, more established monitoring programs like the Breeding Bird Survey.  If found the eBird data to be invaluable for the bird/climate/land-use study I published, and I think you’ll see more papers like this finch study use eBird data in the coming years.
