The 2022 edition of Southern & Central Argentina produced some 296 species with 126 diamond birds of restricted range: testimony to the unique avifauna of Patagonia. Among these, we secured all eight available Argentine endemics and all of Argentina’s 12 endemic breeders, most of which are austral migrants.
The mega target bird of the tour was the now Critically Endangered Hooded Grebe which only breeds in western Santa Cruz province. It took some important logistics, coordination and a huge amount of luck, to see just a single bird. The fate of this stunning species, discovered new to science in 1974, hangs in the balance with all the odds against its survival, mainly due to five years of elevated temperatures, stronger winds and lack of meltwater flow from the Patagonian snowfields; numerous lakes have dried out over the past 25 years. The tour group was relieved to have seen it but, at the same time, bewildered to see a single bird seemingly paired with a Silvery Grebe (a classic survival tactic), and witness its breeding lakes drying out with no nesting material available, knowing that introduced trout, introduced American Mink and wandering predatory Kelp Gulls could thwart any breeding attempt.
The numerous highlights, beyond the tragic plight of the Hooded Grebe, included Spectacled Duck, Red-tailed Comet, Austral Rail, the unforgettable Magellanic Plover, Tawny-throated Dotterel, striking Dolphin and Olrog’s Gulls, a vagrant Macaroni Penguin, raucous Rufous-legged Owl, impressive Magellanic Horned Owl at a daytime roost, the scarce Black-bodied Woodpecker, stunning male and female Magellanic Woodpecker (you have to see both !), the peculiar Black-legged Seriema, and even more peculiar Spot-winged Falconet, the macaw-like Burrowing Parrot, outrageous Scimitar-billed Woodcreeper, whacky outsized tapaculos such as Black-throated Huet-huet and Crested Gallito, both forms of the colourful, skulking, Olive-crowned Crescentchest, the poorly known Dinelli’s Doradito, stunning Black-crowned, Rusty-backed and Salinas Monjitas, Chocolate-vented Tyrant, Rufous-tailed and White-tipped Plantcutters, endangered Pampas Meadowlark and the smart Cinnamon Warbling Finch.
As usual the tour began in Cordoba, central Argentina, where a first visit into the forested foothills provided great views of the handsome and range-restricted Black-and-chestnut Warbling Finch and a superb male Blue-tufted Starthroat. Later in the day we bagged a highly cooperative pair of Chaco Sparrows, an endemic breeder, barely known outside of Argentina.
After a nice pre-dawn breakfast, we headed into the Sierras Grandes to gain altitude before our dawn birding. Our first stops produced a stunning Red-tailed Comet, Buff-necked Ibis, obliging Plumbeous Rail, and a number of perched Black-chested Buzzard-Eagles. The endemic Cordoba and Olrog’s Cinclodes showed well along with White-winged Cinclodes for comparison. Various interesting endemic subspecies were also found including Ash-breasted and Plumbeous Sierra Finches, Puna Canastero, Black-billed Shrike-Tyrant and the distinctive local form of Long-tailed Meadowlark. A shockingly bright lime green Argentine Anole (an iguanid lizard, endemic to these mountains) also put on a fine show.
Dropping down the west slope of the moon-scaped sierras we scoured the thorn woodlands and gardens for the sleek Black-legged Seriema and enjoyed lengthy views of one hunting. Outrageous Scimitar-billed Woodcreeper, smart Lark-like Brushrunner, raucous Brown Cacholote and the beasty “Chaco” Puffbird provided the supporting cast.
A final stop before reaching our hub in the Sierras Chicas produced two male Cinereous Tyrant (a chaco endemic) and our first Many-coloured Chaco Finches and Greater Wagtail-Tyrants. As we left, amazingly a male Black-crested Finch was observed foraging on a street in the town.
Our next objective was the endemic Salinas Monjita, known primarily from the Salinas Grandes salt lakes spanning three provinces and covering an area of over 3700 square miles. First on our agenda today was the enigmatic Spot-winged Falconet and we eventually had corking views of this characterful and scarce falcon. After adding a pair of Crested Horneros, we were itching to reach the salt pans. The monjita only inhabits the low sueda bordering the salt pans and the first of six was found as soon as we stepped out of the bus. A Lesser Shrike-Tyrant put in a brief performance, while back in the chaco woodlands we added the secretive Crested Gallito and poorly known Plain Inezia.
Surreal and beautiful sierran chaco woodlands mixed with Carandilla palms was the setting for another major target, the localized Black-bodied Woodpecker but we would have to work hard for this specialty. In the meantime, we enjoyed point-blank views of the stunning Olive-crowned Crescentchest, of the Andean form argentina. Moving on to another trail we finally scored a superb, Black-bodied Woodpecker flying back and forth across a valley with various perched views to round off an excellent day’s birding.
Our drive across monotonous farmland to Mar Chiquita was punctuated by some unexpected raucous Chaco Chachalacas at a bridge and four Greater Rheas but very little else of note. Once we reached the “Small Sea”, a lake of 2000 sq. km, we immediately homed in and got familiar with the poorly known Dinelli’s Doradito which is common here. The rest of our Mar Chiquita experience included some reasonable looks at the skulking chaco (pallida) form of Olive-crowned Crescentchest, Brown-hooded Gulls, and Dot-winged Crake glimpsed by some. We had an interesting meal that strangely included a lot of Coypu on the menu.
After two short flights we reached our new hub of Bahia Blanca, in the south of the Buenos Aires close to some remnant pristine Pampas grasslands. Our number one target was the endangered Pampas Meadowlark although overnight rain could hamper our endeavour. Several Pampas and now Patagonian birds were new for us including Elegant Crested Tinamou, abundant Burrowing Parrots, Common Miner, the aptly named Firewood-gatherer, White-banded Mockingbird as well as Pampas and Short-billed Pipits to mention a few.
Eventually the mud was too much for our bus and we abandoned it and our driver Roy to continue on foot for the meadowlark, scrutinizing many Long-tailed Meadowlarks and White-browed Blackbirds on the walk. Eventually we reached the spot with a notable change in habitat and ten or more displaying Pampas Meadowlarks…. glorious ! We also had great looks at the crippling Bearded Tachuri. A swirling mass of forty or more Swainson’s Hawk provided great entertainment while leaving the area.
In the afternoon we visited some lakes with the localized Hudson’s Canastero in mind and scored immediately with repeated looks at four individuals. Here too we added Silver Teal, White-cheeked Pintail and Rosy-billed Pochard. Our final stop of the day was the Bahia Blanca estuary where we were treated to scope studies of the endemic breeding Olrog’s Gull with Kelp Gulls for comparison. We also enjoyed Great Grebe, Snowy-crowned Tern, Grey and Semipalmated Plovers, Hudsonian Godwit, White-rumped Sandpiper and Sharp-billed Canastero.
Leaving Bahia Blanca behind, we headed into La Pampa province and a first stop produced sought-after displaying endemic breeders such as Carbonated Sierra Finch and Hudson’s Black Tyrant and now abundant Straneck’s Tyrannulet. Bang, bang, bang !!! Here too, everyone caught up with “in your face” views of Brushland Tinamou, and we had great looks at both Ash-coloured and Dark-billed Cuckoos as well as Blue-crowned Parakeets. After a long drive, we rolled up to a prairie full of Maras playing around, at first nervous, trotting off on all fours, but then they got used to us. I don’t remember ever seeing so many maras at once. More stops produced the stunning endemic Cinnamon Warbling Finch, a pair of endemic Rusty-backed Monjitas, the first of many Patagonian Mockingbirds and distant views of the endemic White-throated Cacholote. At dusk we added stunning views of the Patagonian form (“species”) of Band-winged Nightjar, before a night out on the town where most of us got stuck into some serious seafood paellas and stews, except rib-eye John of course.
At first, Las Grutas doesn’t really look like a birding hotspot, surrounded by low monotonous scrub-steppe. Those bushes are mostly three endemic species of creosote at the south end of the Monte Desert and it turns out to be the number 1 spot for endemics in Argentina with four outright endemics and seven breeding endemics. By now we were missing just a few of these, and soon after dawn we quickly bagged territorial endemic Sandy Gallito, stunning Black-crowned Monjita, endemic Patagonian Canastero, many more Cinnamon Warbling Finches and upgraded our White-throated Cacholote with point blank views.
To feel Patagonia, you have to live it and drive it, and by now we had that feel that nowhere was going to be close, towns were few and far between and the real journey had begun. You drive hundreds and hundreds of miles through wilderness and the scenery can stay the same. You’ve never seen such straight roads or endless horizons. There are no people or towns or villages, and soon you become used to seeing herds of roaming guanaco. So, finally we reach Welsh Patagonia where 4,000 people speak Welsh; bloody mental. A lake in town provided us with parasitic Black-headed Duck among hundreds of Lake Ducks.
No journey to Patagonia would be complete without a visit to a Magellanic Penguin colony. Today we modified the itinerary to visit a different colony knowing that a vagrant Macaroni Penguin had just been found there. The bird seemed quite lethargic but in spectacular plumage and may have been carrying an egg. Meanwhile the scene of thousands of Magellanic Penguins mixed with guanacos was surreal, and unforgettable. We even watch a chick hatching. A viewing platform overlooked an action-packed South American Sea Lion colony, complete with numerous Snowy Sheathbills, Brown Skuas and Dolphin Gulls as Southern Giant Petrels sailed by. The endemic Chubut Steamer Duck proved to be common here, and other additions included now numerous Lesser Rhea, Least Seedsnipe, Two-banded Plover, Rock and Imperial Shags and the near endemic Band-tailed Earthcreeper. Finally, we also had a bizarre experience with a Large Hairy Armadillo trotting around us, presumably looking for handouts.
In the morning we visited a stake-out for Magellanic Horned Owl which was readily found under a bush. With a little extra time on our hands due to flight changes, we made a visit to Rawson and had a productive seawatch from the pier which included Black-browed Albatross, White-chinned Petrel, Manx Shearwater and both Cabot’s and Royal Terns. Embarking a short distance into the ocean we enjoyed repeated looks at several smart Commerson’s Dolphin, a Patagonian endemic, as well as several South American Terns.
On our final morning in Trelew we visited Laguna Negra where the sheer numbers of Chilean Flamingos and ducks, not to mention a flock of over a thousand Wilson’s Phalaropes was extraordinary. Red Shovelers alone may have numbered over ten thousand. A lone Franklin’s Gull was a vagrant here.
After flying to El Calafate we had quite a drive to a remote estancia which would be our base while searching for Hooded Grebe. En route we added the stunning Chocolate-vented Tyrant and scoped a perched Andean Condor.
Soon after dawn we helped ourselves to prolonged scope views of Austral Rail just inside the rush bed which was a great start the day. We re-checked a staging lake for Hooded Grebe drawing a blank and quickly headed up onto the Strobel Plateau. Various quality birds came thick and fast with good numbers of amazing Tawny-throated Dotterels, Grey-breasted Seedsnipe and a White-throated Caracara. Small numbers of Hooded Grebes had been moving between lakes and with most of the lakes now dried out, we had to check all the available water bodies after a bumpy drive in four-wheel-drives. A first lake, where there had been six grebes the previous day, had none although we added Flying Steamer Duck and Andean Ruddy Duck. The next lake had a very low water level and we were surprised to see a Magellanic Plover here. We did our best to enjoy the plover, being such a top bird, but the thought of Hooded Grebe was nagging in the back of the mind, and we had to move on. Another lake drew a blank but did provide us with Patagonian and Greater Yellow Finches, Buff-winged Cinclodes and nearby Rufous-banded Miner. This only left one lake to check. In the distance we could see a pair of grebes that we thought were probably just Silvery Grebes and moved closer just to be sure. They turned out to be a Hooded Grebe seemingly paired with a Silvery Grebe. We got as close as possible in somewhat windy conditions to make the most of it. We had scored with a lot of odds stacked against us. This bird wasn’t there the previous day, and we had run out of options anyway, so luck was really on our side.
Moving on to the picturesque town of El Chalten with its dramatic backdrop of Mount Fitzroy we soon headed to the Patagonian beech forest. This quickly provided us with protracted views of a family group of Spectacled Duck, Striped Woodpecker, Patagonian Sierra Finch, Austral Pygmy Owl, unique White-throated Treerunner, the abundant, yet crippling, Thorn-tailed Rayadito, Chilean Elaenia, Dark-faced and White-browed Ground Tyrants as well as obliging Austral Parakeets much to the joy of Helge. At night we lost no sleep in bagging an amazing pair of Rufous-legged Owls in a 40-minute round trip from the hotel…. no messing !
In the morning we were back in the forest scoring a superb male Magellanic Woodpecker (get innnnn !!!!), an amazing Black-throated Huet-huet nesting in a tree cavity, and a pair of smart Ashy-headed Goose. Back in town we studied the now overdue Rufous-tailed Plantcutter and Chilean Flicker. Moving on to El Calafate we enjoyed close-ups of our second Magellanic Plover.
A full day at the Perito Moreno glacier provided a jaw-dropping experience as we gazed at 100 sq. km of ice, with chunks cracking off and thundering into deep blue water, floating away as icebergs. The park also gave us our now awaited Austral Blackbirds, Dark-bellied Cinclodes and nearby memorable Austral Canastero as well as scope views of a female Magellanic Woodpecker.
On the final morning we added the fantastic Many-colored Rush Tyrant and several Magellanic Snipe to round off a magnificent tour.
