Bolivia's Avian Riches 2013
Sep 7, 2013 to Sep 22, 2013

Once again, we pulled off another visit to South America's best-kept birding secret: Bolivia. Although landlocked, Bolivia competes with the likes of Venezuela and Ecuador in having one of the most diverse avifaunas in the world, in a tier just behind the likes of Colombia, Peru, and Brazil. And our tour gave us an idea of why: the sheer variation of habitats available! We have few (if any?) tours that span the changes from nearly flat tropical savanna, humid foothill forest, dry intermontane forest and desert scrub to humid montane forest, above-treeline grasslands, and altiplano.

And we had a good run of birds, too! A total of 438 species, with highlights including two magnificent hillstars: the charismatic (and endemic) Wedge-tailed, and the more widespread but still lovely Andean. We also managed to net other memorable birds, such as the colorful Hooded Mountain-Toucans that lounged beside us after gorging on some fruits, the boldly colored (but skulky) Olive-crowned Crescentchest that moused around in montane scrub before (at long last!) making itself visible to us, the pair of Andean Avocets resting in an altiplano marsh, the graceful Swallow-tailed Kites enjoying thermals over humid montane forests, the surprisingly colored Crimson-mantled Woodpecker, the Giant Conebill pair that showed up out of nowhere and sang away as we gawked, the chubby Barred Fruiteater that piped off like a steam whistle now and then, the Scissor-tailed Nightjar that paraded his long tail in front of us at dusk, the Gray-breasted Seedsnipe that, despite sitting beside us, escaped notice until we flushed them up, the moth-like Short-eared Owl we watched as it enjoyed its lunch, or (of course) Keith's plastic bag (you didn't think I'd remember that, did you, Keith?).

These sightings, but also the good company, made this tour quite memorable. I hope we have another opportunity to meet up again and raise our binoculars to toast more good birds! Until then, "buen pajareando y que nos vemos pronto!"

SAVANNA HAWK (Buteogallus meridionalis)
ROADSIDE HAWK (MAINLAND) (Rupornis magnirostris saturatus) – These birds look quite different from more northerly populations, but they seem to interbreed broadly in SE Peru.
HARRIS'S HAWK (Parabuteo unicinctus)
WHITE-RUMPED HAWK (Parabuteo leucorrhous) – Great experience with one of these rare raptors! Called it in for views and it sat there until we were bored.
WHITE-TAILED HAWK (Geranoaetus albicaudatus)
VARIABLE HAWK (Geranoaetus polyosoma) – This species presently contains "Red-backed" and "Puna" hawks. If these should ever be split in the future, both were seen on the trip (mostly Red-backed, but Puna was seen well where we had Puna Miner).

SLATE-COLORED COOT (Fulica ardesiaca) – Also called "Andean Coot".
Aramidae (Limpkin)

Perhaps the most unexpected sighting of the tour was this Short-eared Owl. There are likely fewer than a dozen records for the species in Bolivia. (Photo by guide Dan Lane)

Cuculidae (Cuckoos)
SQUIRREL CUCKOO (Piaya cayana)
GUIRA CUCKOO (Guira guira)

FERRUGINOUS PYGMY-OWL (Glaucidium brasilianum) [*]
BURROWING OWL (Athene cunicularia)
SHORT-EARED OWL (Asio flammeus) – A bird at the Achacachi marshes was only my second record for Bolivia (there may be fewer than 10 for the country)! We watched it hunting, then catching and eating a prey item. A lifer for at least two folks!
Caprimulgidae (Nightjars and Allies)
RUFOUS NIGHTJAR (Antrostomus rufus) – A bird showed well in flight at Laguna Volcanes.

GIANT HUMMINGBIRD (Patagona gigas gigas) – Yep, pretty big!
BLUE-TUFTED STARTHROAT (Heliomaster furcifer) – A young male molting in adult plumage at Lomas de Arena was great, the first time I’ve had it on the tour.
WHITE-BELLIED WOODSTAR (Chaetocercus mulsant) – That Jetson's scooter sound is a great way to locate males.
GLITTERING-BELLIED EMERALD (Chlorostilbon lucidus)
WHITE-BELLIED HUMMINGBIRD (Amazilia chionogaster hypoleucus) – This southern subspecies is pretty distinctive (by voice, at least) from Peruvian birds. One to keep an eye on...

BLACK-FRONTED NUNBIRD (Monasa nigrifrons)
Capitonidae (New World Barbets)
VERSICOLORED BARBET (Eubucco versicolor) – It took a while for everyone to get on the lovely male at Miguelito, but I think we were successful in the end.
Ramphastidae (Toucans)
BLUE-BANDED TOUCANET (Aulacorhynchus coeruleicinctis) – Paul noticed the first one at Miguelito, and we had them a few more times later.
HOODED MOUNTAIN-TOUCAN (Andigena cucullata) – Our ‘long day’ at the Nor Yungas started with a distant pair calling (only I got to see one across the valley). We eventually gave up on them and drove down the road, and at the next stop another pair started bill-rattling just beside us, and came in for fantastic looks, lazing away in fornt of us after foraging. Shortly thereafter, a *third* pair started calling upslope nearby! Wow.

GREEN-BARRED WOODPECKER (GOLDEN-BREASTED) (Colaptes melanochloros melanolaimus) – This highland form (also getting into the Chaco) is fairly distinctive from the true Green-barred of the Pantanal, Beni, and points east. Thanks to Ann-Charlotte for spotting it!
ANDEAN FLICKER (Colaptes rupicola)
CAMPO FLICKER (Colaptes campestris)
CRIMSON-CRESTED WOODPECKER (Campephilus melanoleucos)
Cariamidae (Seriemas)
RED-LEGGED SERIEMA (Cariama cristata) – Keith's sharp eyes once again nailed this desired target. Good thing, too, since the river cut us off from arriving at the best spot for the species at Lomas de Arena!

MITRED PARAKEET (Aratinga mitrata)
WHITE-EYED PARAKEET (Aratinga leucophthalma)
RED-FRONTED MACAW (Ara rubrogenys) – Distant views this year, but still a pretty nice experience. That sad captive individual at our hotel in Comarapa was a heart-breaker, though. [E]

BLUE-WINGED PARROTLET (Forpus xanthopterygius)
BLACK-WINGED PARROT (Hapalopsittaca melanotis) – Several in flight over the Empalme sideroad forest in Siberia showed moderately well. Still better than my normal experience (“none”).

WHITE-BACKED FIRE-EYE (Pyriglena leuconota)
Melanopareiidae (Crescentchests)
OLIVE-CROWNED CRESCENTCHEST (Melanopareia maximiliani) – Always a crowd-pleaser, and this year's made us work for it, which made the final good views that much sweeter!
Conopophagidae (Gnateaters)
SLATY GNATEATER (Conopophaga ardesiaca) – Crappy views at Laguna Volcanes were upstaged by much better views at Miguelito.
Grallariidae (Antpittas)
RUFOUS ANTPITTA (Grallaria rufula cochabambae) – A very obscured scope view at Corani reservoir will have to do.
RUFOUS-FACED ANTPITTA (Grallaria erythrotis) – After hearing many, we finally saw one (thanks to Carlos!) at the Corani hydroelectric road. [E]
OCHRE-BREASTED ANTPITTA (Grallaricula flavirostris boliviana) [*]

GREATER THORNBIRD (Phacellodomus ruber)
CREAMY-BREASTED CANASTERO (CREAMY-BREASTED) (Asthenes dorbignyi dorbignyi) – Another species complex ripe for splitting. If it is, this population will remain 'dorbignyi' as it is the nominate form.
BERLEPSCH'S CANASTERO (Asthenes berlepschi) – Highly localized and endemic... and hanging on despite the habitat fragmentation it's suffered around Sorata. [E]
SCRIBBLE-TAILED CANASTERO (Asthenes maculicauda) – Scribbles seen. Check. Moving on.
STREAK-THROATED CANASTERO (Asthenes humilis) – At Pongo, La Paz.

CHOTOY SPINETAIL (Schoeniophylax phryganophilus) – The Dickcissel of spinetails, which showed well at Lomas de Arena.
YELLOW-CHINNED SPINETAIL (Certhiaxis cinnamomeus) – A pair at Laguna Volcanes was unexpected.
SOOTY-FRONTED SPINETAIL (Synallaxis frontalis)
AZARA'S SPINETAIL (Synallaxis azarae) – Common and pesky (because it can be hard to see) little pip-squeaks.
PLAIN-CROWNED SPINETAIL (Synallaxis gujanensis certhiola) – This population is a 'bridge' between the grayer western Amazonian birds and the fawn-breasted White-lored Spinetail (S. albilora) to the east. In the end, I expect this population to be merged with the latter (it is indistinguishable by voice).
OCHRE-CHEEKED SPINETAIL (Synallaxis scutata) – Not much better than the Azara's for difficulty of seeing.
Tyrannidae (Tyrant Flycatchers)
SOUTHERN BEARDLESS-TYRANNULET (SOUTHERN) (Camptostoma obsoletum bolivianum) – Best identified by the bic razor they carry in their vest pocket.

CATTLE TYRANT (Machetornis rixosa)
DUSKY-CAPPED FLYCATCHER (Myiarchus tuberculifer) [a*]
GREAT KISKADEE (Pitangus sulphuratus) – The birds in Cochabamba city are a peculiar large subspecies with a washed out yellowish belly called 'bolivianus'. They sound much like other kiskadees elsewhere, so I doubt they'd be anything separable down the road, but Bolivia is the only place that the species gets up to the treeline (we heard one at 3150m)!

TROPICAL PARULA (Setophaga pitiayumi)
THREE-STRIPED WARBLER (BOLIVIAN) (Basileuterus tristriatus inconspicuus) – These birds have a much higher-pitched voice than birds from southern Peru (such as at Manu) and north. I suspect a split in the near future.
CITRINE WARBLER (Myiothlypis luteoviridis euophrys) – Another bird with a very different Bolivian population, both vocally and in appearance.
PALE-LEGGED WARBLER (Myiothlypis signata)
TWO-BANDED WARBLER (Myiothlypis bivittata) – Common around Laguna Volcanes.
SLATE-THROATED REDSTART (Myioborus miniatus) – A few birds around Miguelito.

BLUE-WINGED MOUNTAIN-TANAGER (Anisognathus somptuosus flavinuchus) – This subspecies, found from about Manu and south, is very different in voice from birds to the north of that site. A split is eminent.

Rufous-browed Peppershrike can be found in most of the countries in Central and South America, and being very vocal it's frequently recorded on lists daily. But it is always a delight to actually see one this well. (Photo by participant Paul Koker)

GRASS-GREEN TANAGER (Chlorornis riefferii)
CHESTNUT-BELLIED MOUNTAIN-TANAGER (Delothraupis castaneoventris)

GREENISH YELLOW-FINCH (Sicalis olivascens) – Only at the little village on the drive from Comarapa to Cochabamba.
SAFFRON FINCH (PELZEN'S) (Sicalis flaveola pelzelni) – I'm still not certian if birds in the lowlands and highlands are the same form... my review of the taxonomy of the species doesn't help resolve this question, but it's a vexing one for me, as they seem duller and more streaked in the highlands.
GRASSLAND YELLOW-FINCH (Sicalis luteola) – Only at the edge of Titicaca.
GREAT PAMPA-FINCH (WESTERN) (Embernagra platensis olivascens) – These birds are a different form from those in the Beni.

RUFOUS-COLLARED SPARROW (Zonotrichia capensis) – Yup.
COMMON BUSH-TANAGER (Chlorospingus ophthalmicus) – As a nice twist, we now know this 'tanager' is actually a 'finch' based on genetic studies.
Cardinalidae (Cardinals and Allies)
HEPATIC TANAGER (Piranga flava) – This is one of the former tanagers that we now know to be a cardinal relative! This population is from the 'highland' group, should the species be split up.
BLACK-BACKED GROSBEAK (Pheucticus aureoventris) – A South American relative of Rose-breasted and Black-headed grosbeaks, and also rather attractive.
ULTRAMARINE GROSBEAK (Cyanocompsa brissonii) – We tried to see some in the dry Valle area around Comarapa, but they weren't playing well.

SHINY COWBIRD (Molothrus bonariensis)
GIANT COWBIRD (Molothrus oryzivorus)
VARIABLE ORIOLE (CHESTNUT-SHOULDERED) (Icterus pyrrhopterus pyrrhopterus) – Formerly part of 'Epaulet Oriole', but that species has been split and the more northerly forms merged with 'Moriche Oriole'.
MOUNTAIN CACIQUE (BOLIVIAN) (Cacicus chrysonotus chrysonotus) – Southern birds sometimes separated from northern ones due to the lack of yellow on the wing, but in central Peru, they seem to interbreed freely.
