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!

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

GREAT RUFOUS WOODCREEPER (Xiphocolaptes major) – Well named, we saw this large woodcreeper on several days.
BUFF-THROATED WOODCREEPER (Xiphorhynchus guttatus) – One of the most widespread woodcreepers in Amazonia (and tributaries that enter more open habitats such as the Beni).

PALE-LEGGED HORNERO (Furnarius leucopus) – More strongly tied to gallery forest here (otherwise, a widespread Amazonian species) than the Rufous, we saw it at La Habana.
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]

THRUSH-LIKE WREN (Campylorhynchus turdinus unicolor) – Unlike Amazonian birds, those from the Beni and Pantanal are unmarked.
FAWN-BREASTED WREN (Cantorchilus guarayanus) – Similar to the widespread Buff-breasted Wren, but has a distinctive call note.
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.

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.
