Bolivia's Avian Riches 2016 Extension: Bountiful Beni -- Bazillions of Birds
Aug 29, 2016 to Sep 4, 2016
Dan Lane

THE regional specialty of the Beni is this gorgeous Blue-throated Macaw, which we were all thrilled to see so well. Photo by participant Brian Stech.

As the subtitle of this extension suggests, the Beni is a very birdy place! Less well known than their larger cousin, the Pantanal, the seasonally flooded wetlands of the region are nevertheless astounding in their abundance of life. The sheer numbers of Jabiru, Capybara, ibis, vultures, caracaras, egrets, whistling-ducks, caimans, Southern Screamers, and other birds and animals leave you gobsmacked… Then there are all the smaller species that astound once you start looking and listening! We were lucky to have been able to see some of the specialties of the region, such as Blue-throated Macaw, Plain Softtail, and Velvet-fronted Grackle, before the big cold front hit. The change in weather was striking (and chilling!), and birding became a bit harder in the face of the cold wind. But one must take advantage of opportunities, and seeing the big migration event of martins and swallows that were stopped because of the strong headwinds was quite a sight!

Birding the Beni is always a pleasure, and it was doubly so to enjoy it with you all. Glad you got to see this amazing corner of the world before we departed on the main Bolivia tour!

Note: Don't forget, too, to have a look at the separate triplist for the main section of this tour.

One of the following keys may be shown in brackets for individual species as appropriate: * = heard only, I = introduced, E = endemic, N = nesting, a = austral migrant, b = boreal migrant

There is something decidedly prehistoric about a Greater Rhea. Photo by participant Brian Stech.

Furnariidae (Ovenbirds and Woodcreepers)
OLIVACEOUS WOODCREEPER (AMAZONIAN) (Sittasomus griseicapillus viridis) – Seen at La Habana, but common in most woodlands in the area. This species will surely be split into several at some point. This population will either be part of the "Amazonian" group (as suggested by Clements' list here) or may be on its own. Vocally, it's pretty different from other Amazonian populations.
GREAT RUFOUS WOODCREEPER (Xiphocolaptes major) – A pair in the rain around the ranch house.

RUFOUS CACHOLOTE (Pseudoseisura unirufa) – The jay of the furnariids, and a lovely bird!

PLAIN-CROWNED SPINETAIL (Synallaxis gujanensis inornata) – This population is presently part of "Plain-crowned" Spinetail, but it is actually part of the "White-lored" Spinetail group vocally. Expect to see that shift in the future!

PEARLY-VENTED TODY-TYRANT (Hemitriccus margaritaceiventer) – Seen best near Santa Cruz city our first day.

WHITE MONJITA (Xolmis irupero) – A very attractive tyrant that acts rather bluebird-like.
BLACK-BACKED WATER-TYRANT (Fluvicola albiventer)
WHITE-HEADED MARSH TYRANT (Arundinicola leucocephala) – Brian got us on the first of these on the lily pond of our Trinidad hotel.

The boldly patterned Green-barred Woodpecker showed nicely on several occasions. Photo by guide Dan Lane.

Donacobiidae (Donacobius)
BLACK-CAPPED DONACOBIUS (Donacobius atricapilla) – A very entertaining species to watch as it performs duets with flared and waggling tails and inflated throat sacs. Now considered a monotypic family.
Turdidae (Thrushes and Allies)

UNICOLORED BLACKBIRD (Agelasticus cyanopus)
GRAYISH BAYWING (Agelaioides badius) – Bay-winged Cowbird has been split into two species (this and the Pale Baywing of NE Brazil)... and it's been shown not to be a cowbird, hence the change in English name.

GIANT COWBIRD (Molothrus oryzivorus) – Only seen our last day in Beni.
VARIABLE ORIOLE (Icterus pyrrhopterus) – Formerly part of "Epaulet Oriole," but recent studies have shown that the yellow-shouldered forms of Amazonia are better considered a separate species from these chestnut-shouldered birds of eastern South America.
