2019 Resolution: 100 Species or Bust!

After catching the birding bug a few years ago, and recently creating an account here on Inaturalist, the pursuit of biodiversity has become a bit of an obsession for me. I think it’s a healthy one though, as it invariably leads me outdoors to new and strange places where I meet new animals and new people. Before I’d even heard of Inat I was sitting inside on a -25 degree January day wishing I was out exploring the world. On that thought, I decided to start 2019 with a resolution/goal of seeing as many new species of animal as possible. I decided to set a target of 100 species of vertebrates, assuming insects and other inverts would likely push me past 100 in no time at all. Since wildlife photography was already a hobby of mine, I figured this was destined to be a resolution I might actually stick to!
My year of exploration started slowly in the grip of an especially cold Iowa winter, and my first new species didn’t come along until February 1st, when on the way to work I was surprised to spot a Gyrfalcon munching on a ground squirrel in a snowy farm field. Another month passed with no new species, and I began to realize my eyes may have been bigger than my stomach. I’d already recorded the majority of the common vertebrate species in my area, and there weren’t many easy additions to make. I would have certainly failed my mission if it were not for a fortuitous road trip with a close friend to the Rio Grande valley of Texas, a mecca for wildlife enthusiasts and especially bird watchers. We had planned our trip over 8 days in early April, the peak of migration in south Texas, and had a target list of over 50 species of birds neither of us had seen before.
The trip began on a cold morning in Iowa City, headed south for the next 22 hours we couldn’t resist an early stop at a Prairie chicken lek in southern Iowa which earned us the state endangered Greater Prairie Chicken, our first lifer of the trip! We pushed south through the rest of day and night to our fist Texas location, the Hill Country, which divides fauna of the southeast from the southwest. Here we encountered endemic species such as the Golden-cheeked Warbler, woodpecker, White-tipped dove, and Rufous-crowned sparrow. It was after this that we received word through the birding grapevine that an extremely rare Mexican species, the Yellow Grosbeak had been appearing at a backyard bird feeder in the tiny town of Concan. We took a chance and diverted the couple hours to the little resort town. After getting to know the homeowner we were sitting in their beautiful backyard, and within minutes the star of the entire trip was busily feeding just feet away! was one of only a dozen or so records of this species in the United States. Spirits up, we drove on the remaining 4 hours to Kingsville, TX to get our first real sleep in the last 36 hours and to prepare for an all-day guided tour of King Ranch the next morning.
King Ranch is legendary amongst birders, and it was a smorgasbord of new southern species. Crested Caracara, Greater roadrunner, Harris’s hawk, and Olive Sparrow abounded. On our tour, we also managed to see and photograph all of the King ranch “Big 5”, the five most desired species in the area. Ferruginous pygmy Owl, Audubon’s Oriole, Northern Beardless tyrannulet, Sprague’s Pipit, and Tropical Parula all made prolonged appearances! On the tour, I divided my attention between the sky for birds and the sandy scrub for reptiles, I was rewarded with Texas horned lizard keeled earless lizard, two target species for the trip. In true mad-birder style we decided to forego dinner after departing king ranch and check just one more spot. The grounds of Quinta Mazatlán, in the border city of Brownsville TX, rewarded us with Broad-billed hummingbird, Plain Chachalaca, and Common Paraque as the sun set on our second day in Texas. Day two closed with 29 birds, 2 reptiles and 1 mammal, a heard of feral nilgai, (an Indian antelope species) adding to the tally. Day three in TX was nothing short of spectacular, and after a short morning trip to Estero Llano Grande, 10 more bird species were added to the list. Alligators and Rose-bellied lizards, Common Spotted Whiptails, a 6 and-a-half foot Bullsnake, and Western Ribbon Snake were all seen in the space of an hour. Four more lifer reptiles made the list. The biggest surprise of the day was a low-flying Swallow-tailed Kite, a rarity in the valley, and one of my favorite birds. Green Jays, a jewel of the valley were also a treat! night a side trip to Bentsen Rio Grande State Park had us (and about 30 other eager bird watchers) looking up at a small hole in a telephone pole as the last rays of light faded, hoping to catch a glimpse of another south Texas specialty, an Elf Owl. After an hour of staring the tiny head popped out and everyone got great looks at the bird. Cave swallows migrating up the Rio Grande, and a family of Collared peccaries rounded out the night.
Over the next couple days, we returned to Estero llano Grande to see more incredible birds like White-tailed Kite, Gray Hawk, and Great Kiskadee, stood in a Red Lobster parking lot to witness the mass roosting of Green parakeets and Red-lored parrots on the power lines of Brownsville, we saw White Ibis and Roseate Spoonbill in wetlands and Green and Ringed Kingfishers at local parks. At Quinta Mazatlán, we got special access and a brief glimpse of a Crimson-collared grosbeak, another rarity that had shown up recently. By the end of day six we had tallied 51 new species of birds, half a dozen reptiles, 3 more mammals, (Nutria, Rio Grande Ground Squirrel, and Hispid Cotton rat). We had already exceeded our expectations for the whole trip! With two days to go we headed for the coast, to the legendary South Padre Island.
Here the shorebirds and seabirds abounded, and Black skimmers, another favorite of mine were seemingly everywhere. By wonderful coincidence a Varied Bunting appeared at the visitor’s center, a beautiful rarity we had searched fruitlessly for earlier in the trip. our way up the coast to Houston we stopped by a nesting platform for the endangered Aplomado Falcon. Luckily for us, there was a female resting on the nest, after this we continued north to Bolivar flats to catch a glimpse of Snowy and Wilson’s plovers, and a surprise Clapper Rail in the intertidal marshes. Finally, a stop outside Houston at WG Jones State forest to see the western-most population of Red-cockaded Woodpecker and Brown-capped Nuthatches. As we left southern Texas we knew the trip had exceeded our wildest expectations. I had recorded 65 life birds, 9 reptiles, 1 amphibian, 4 mammals, and 7 fish.
Whew, suddenly 100 species didn’t seem too far out of reach! With the Texas trip included, I was at 88 new species, and it was only mid-April! Eight months and 12 species to go!

100 Species or Bust: May-October

My goal of seeing 100 species had become much more attainable after the influx of sightings in south Texas. Now, with only 12 to go, I had spring in Iowa to look forward to! In the first three weeks of May I had the fortune to see three new species of wood warbler, Cape May, Mourning, and the very hard to find Connecticut warbler. after I stumbled across an American bittern at a local park in Iowa city, a bird I had been trying to find for years! singing Eastern Whip-poor-will and a Black-billed Cuckoo in June were nice additions, although both avoided photos! In August a Yellow-billed Loon was found in central Iowa, a bird that should be in northern Alaska! 4 to go! Later that week I found a Plains Leopard frog in my own backyard to make it 97. A surprise trip to Florida to visit friends was planned for the end of August, and #100 was in my sights. On Sanibel Island the first day on the beach yielded Boat-tailed Grackle, Limpkin, and then with 100 in sight, A Gray kingbird on Captiva Island became the magic 100th species! missing a beat I upped my goal to 125 and explored more of the parks in the area. In Naples I saw Gopher Tortoises, And on a short boat trip in the mangroves of Cape Coral, we saw West Indian Manatee and a flock of over 100 Magnificent Frigatebirds! our friend’s apartments, invasive species like the Cuban tree frog and Tropical House Gecko by porch-light. Florida softshell turtle, Red-bellied Cooter, Oscar Tilapia, and Peninsular Cooter were seen in 6-mile Cypress slough. On the last day, I spied a Short-tailed Hawk while enjoying the pool, and a pair of Snail kites hunting on the way back to the airport to return to Iowa. I left Florida with 112 species for the year, with plenty of time to add a few more!
Back home in Iowa I got to explore a bit with some herping buddies and turned up my first Boreal chorus frog, and the state endangered Blue-spotted Salamander, guys were a real treat to see! My final species of 2019 as of Oct. 29th was a lone Sabine’s gull that appeared at a nearby lake, this arctic gull is certainly enjoying the early snow this week as winter rolls back into the Midwest. I sit at 115 species for 2019, I better save a few for 2020!
