Bolivia's Avian Riches 2014: Bountiful Beni Extension
Sep 1, 2014 to Sep 6, 2014
Dan Lane

A common but charismatic Rufous-browed Peppershrike posed nicely for guide Dan Lane to capture this cover shot.

This was another wonderful visit to the Beni, a region of northern Bolivia that is the remnant of an inland sea or lake that drained through the Madeira Arch several hundred thousand years ago, but still fills with water during the wet season. In fact, the wet season of 2013-14 was one of record flooding! Happily for us (if not for the residents of the region), most signs of this flooding event were gone, and we were able to enjoy our visit unencumbered. Local guide Lyliam was her usual charming self, and despite perhaps somewhat rustic accommodations, we enjoyed (too much!) wonderful food and great birding!

The latter is particularly fine in this part of the world. As we saw, there is an impressive variety of habitats resulting in high diversity in this environment. Many birds we encountered are those also in the Pantanal of the Brazil-Bolivia-Argentina region, and the open water pans, the open palm savannas, and islands of low tree tangles certainly look just like those of the Pantanal. However, the Pantanal wetlands drain into the Rio Paraguay and thence into the Rio de la Plata (passing by Buenos Aires on its way to the Atlantic).

By contrast, the Beni wetlands drain into the Rio Mamore, which is a tributary of the Rio Madeira, one of the largest of the Amazonian tributaries. As a result, the Beni has a decidedly Amazonian flavor, particularly along the rivers that host gallery forest. Our last morning was in such gallery forest at La Habana and we enjoyed a little taste of it on our boat ride along the Rio Ipurupuru. In this habitat, we encountered Amazonian species such as Band-tailed Manakin, Dull-capped Attila, several antbirds, various woodcreepers, the odd Hoatzin, Black Hawk-Eagle, Blue-headed Parrot, several canopy tyrants, a trogon or two, and more.

By contrast, in the more open country, where visibility is better, we spied flocks of seedeaters and seed-finches (wow, that flock of Large-billed Seed-Finches was amazing!), lots of waterbirds, tyrants, lots of furnariids with their large and noticeable nests (such as the mud oven of the Rufous Hornero or the large stick nests of Greater Thornbird and Rufous Cachalote), and raptors. Two Long-winged Harriers and a young Crowned Eagle the day we drove from Trinidad to Cutal were particularly memorable! In all, it was a fine visit, even if we missed one of the headliners (Blue-throated Macaw). For the few days we were there, the diversity we enjoyed was staggering! I was pleased all the participants who signed up for the main tour also decided to do the extension. I hope you enjoyed it as much as I, and that we see each other again with binoculars around our necks somewhere down the road!

Good birding!

ROADSIDE HAWK (MAINLAND) (Rupornis magnirostris saturatus)

This Savanna Hawk was extremely cooperative. (Photo by guide Dan Lane)

STRAIGHT-BILLED WOODCREEPER (Dendroplex picus) – A widespread open-country woodcreeper.
RED-BILLED SCYTHEBILL (Campylorhamphus trochilirostris) – We enjoyed views of this peculiar woodcreeper on the drive to Cutal, and a few times there as well.
NARROW-BILLED WOODCREEPER (Lepidocolaptes angustirostris) – One of the the more distinctive woodcreepers around, often boldly perching on fence posts in the open.

RUFOUS HORNERO (Furnarius rufus) [N]
GREATER THORNBIRD (Phacellodomus ruber)
PLAIN SOFTTAIL (Thripophaga fusciceps fusciceps) – Although the species (as it's currently recognized) is widespread in Amazonia, the nominate form is endemic to Beni, and will likely be split sometime in the future. [E]

Polioptilidae (Gnatcatchers)
MASKED GNATCATCHER (Polioptila dumicola berlepschi) – The birds here were whiter-bellied whereas those in the 'valles' region in the mountains are deeper bluish below.
Donacobiidae (Donacobius)
BLACK-CAPPED DONACOBIUS (Donacobius atricapilla)

Thraupidae (Tanagers and Allies)
RED-CRESTED CARDINAL (Paroaria coronata) – The irony isn't lost on me that this genus of 'cardinals' are tanagers, whereas the North American 'tanagers' are in fact cardinals!

DARK-THROATED SEEDEATER (Sporophila ruficollis)
RUFOUS-RUMPED SEEDEATER (Sporophila hypochroma)
LARGE-BILLED SEED-FINCH (Sporophila crassirostris) – After comparing my photos, I am swayed that the incredible flock (150+!) we had around Trinidad was this species, not Great-billed. An amazing sight!

RUSTY-COLLARED SEEDEATER (Sporophila collaris) – A large-billed species we saw in small numbers.

WHITE-BROWED BLACKBIRD (Sturnella superciliaris) – A red-breasted small meadowlark.
VELVET-FRONTED GRACKLE (Lampropsar tanagrinus boliviensis) – This species is widespread in western Amazonia, but this subspecies, which is much larger, is only found in Bolivia. We saw a lot of them on this visit! [E]
CHOPI BLACKBIRD (Gnorimopsar chopi) – The non-stop whistling we heard most places.

YELLOW-HEADED SIDENECK TURTLE (Podocnemis unifilis) – I didn't notice it at the time, but the big turtle we picked up on the trail out to the macaw palm island had four neat holes in its shell, probably the marks from a jaguar's teeth!


Totals for the tour: 246 bird taxa and 9 mammal taxa
