Argentina - December 2005 birding trip report - Trip Species' Lists - Birding the Americas Trip Report Repository

Latin names taken from Avibase, Bird Checklists of the World, accessed via Denis Lapage’s Bird Links to the World, http://www.bsc-eoc.org/links/links.jsp. Common name boldface are FT lifers.

Iguazu = Iguazu National Park, Puerto Iguazu and vicinity (most birding at Macuco Trail, along paved road to the Sheraton, along Road 101, a paved road leading into Iguazu National Park not far from the airport, a small woodland area near Puerto Iguazu, and the Hummingbird Garden in Puerto Iguazu; full details on these sites in the accompanying trip report)(Dec 3-6, 2005)

Ibera = Edge of Esteros del Ibera, northeast of Carlos Pellegrini in Corrientes Province; set odometer to “0” at the junction of Road 40 and Highway 14 (see further details in trip report) (Dec. 6-7, 2005)

San Luis = Private Ranch in Southeastern San Luis Province (see trip report for details) (Dec. 9-10, 2005)

Terms such as “abundant”, “common” or the like are used loosely, and not with any precise definition. Generally, “Abundant” means very common in large numbers and easily encountered in the location identified; “common” means easily seen every day but in smaller numbers; “fairly common” means seen easily, but not every day; for species less common that those I usually identify the actual number seen.

Thanks to Alvaro Jaramillo for his review of this list and resulting comments and corrections. I’m sure those who go on HIS trips don’t have so many conundrums and missed “mystery” birds as we did when on our own!

Total of 301 bird species noted, including “Dowitcher sp.” and lumped Golden-breasted and Green-barred Woodpeckers (10 of total “heard only”).

SANDPIPERS
Dowitcher sp.	Limnodromus sp.	3 for sure in BA; we thought there were more, but didn’t take particular note of them not realizing that this is an unusual species for Argentina. We originally noted these basic-plumaged birds as “Long-billed” based solely on their inclusion in the field guide. We have since learned that Short-billed may be the expected Dowitcher in Argentina. Since we heard no vocalizations these now become “Dowitcher sp.” I hope some experienced local birders also saw and identified these birds more carefully than we did.

OWLS
Ferruginous Pygmy-Owl	Glaucidium brasilianum	1 responded to imitations of its call (which were being used to stir up other species) and even appeared on a nearby branch, in Iguazu; 1 heard at San Luis, but there seems to be considerable debate on the correct taxonomy for this and Austral Pygmy Owl in that part of Argentina—what we heard SOUNDED like a fairly typical Ferruginous, but I have no experience with Austral

Campo (Field) Flicker	Colaptes campestris	All locations
Lineated Woodpecker	Dryocopus lineatus	1 along Macuco Trail, Iguazu

Planalto Woodcreeper	Dendrocolaptes platyrostris	1 seen and heard along Road 101 in Iguazu

TYPICAL ANTBIRDS

MANAKINS
White-bearded Manakin	Manacus manacus	Several seen along the Macuco Trail in Iguazu; the loud snap alerted us to the birds’ presence
Blue (Swallow-tailed) Manakin	Chiroxiphia caudata	3 fairly high up in a tree along the Macuco Trail in Iguazu; at first glance we thought they were tanagers!
TYRANT FLYCATCHERS
Southern Beardless-Tyrannulet	Camptostoma obsoletum	Iguazu, BA, San Luis
Yellow Tyrannulet	Capsiempis flaveola	Common at Iguazu; easier to locate once we learned its song
Yellow-bellied Elaenia	Elaenia flavogaster	Iguazu
White-crested Elaenia	Elaenia albiceps	All at San Luis. We had a little confusion over this and the next species. All of the many birds of these two species that we saw had very prominent, triangular white patches on the crest and nape, leading us to call them all White-crested. We also heard many vocalizations from less-well-seen birds that perfectly match the call of the more common Small-billed. With some hesitation, then, we’ll claim both, but put it on the list to observe more carefully next time
Small-billed Elaenia	Elaenia parvirostris	See comments above. Probable migrants, as we saw one large flock of 7 birds in one tree that were probably this (and not the previous) species.

Eared Pygmy-Tyrant	Myiornis auricularis	2 along Road 101 in Iguazu
Southern Antpipit	Corythopis delalandi	Heard only along Macuco Trail; call was very distinctive; bird must have been 5 feet away and we couldn’t quite get a clear look

Bran-colored Flycatcher	Myiophobus fasciatus	2+ at San Luis
Euler's Flycatcher	Lathrotriccus euleri	Seen briefly along Macuco Trail in Iguazu, but call clinched the ID

THRUSHES
Rufous-bellied Thrush	Turdus rufiventris	Iguazu, BA; the most common thrush in BA, with many in city parks and along wooded avenues
