The Bolivian subspecies of the Swallow-tailed Cotinga Phibalura flavirostris
merits recognition as a species, says Bennett Hennessey, Executive Director of BirdLife’s Bolivian Partner Asociación Armonía, in a paper just published in The Wilson Journal of Ornithology
Now reduced to fewer than 600 individuals in a few fragments of forest within an area of just over 1,000 km2
, the “Palkachupa Cotinga” will be a candidate for a high threat category in the 2012 Red List update by BirdLife International
Unrecorded for 98 years, P. f. boliviana
was rediscovered at the edge of a small (2-4 km2
) forest fragment near Pata, north-west of the municipality of Apolo in Bolivia’s Madidi National Park, in September 2000.

Bennett Hennessey rediscovered the bird, and is now leading Armonía’s efforts to conserve it. It is still relatively common in patches of good habitat, but with so little good habitat remaining the population is very low. A stronghold of the population has been found at the original collection site, near the village of Aten.
“Without more support, we have another dry season on the horizon, during which more of Palkachupa’s habitat will be cut and burnt for pasture land,” says Bennett Hennessey. Armonía is seeking donations of $3000 to $5000 to protect the Palkachupa Cotinga (see end of story for details on how you can help).
In June 2010, Armonía achieved the first step toward the creation of a Palkachupa Nature Reserve with the purchase of 59 ha near Aten. Negotiations with landowners continue, and they hope to purchase additional land. “The area requires complete boundary fencing to prevent further cattle grazing, and to allow reforestation. Restoration of savannah breeding habitat is needed, and for this we will first need to work with neighbouring landowners on fire management. Isolated trees will be planted to improve nesting habitat" said Bennet Hennessey.

“We will initiate a programme of protecting Palkachupa Cotinga nesting trees in the Aten area by purchasing the protection rights of important trees. These trees will be fenced off, and signs will be placed declaring these small areas as sanctuaries for nesting Palkachupa.”
It would not be possible to protect the Palkachupa’s habitat without the support and cooperation of the people of Aten. Armonía is working with a former Madidi park guard and Aten native, William Ferufino, to coordinate research and outreach activities with the local communities.
Local people have responded enthusiastically, and images of Palkachupa play a prominent role in annual Independence Day celebrations. Four high school students are working with William Ferufino as volunteer field assistants. In recognition of this important support, and to build greater local participation, Armonía provided assistance for improvements to the Aten school, including construction of three additional classrooms.
The Near Threatened Swallow-tailed Cotinga has traditionally been considered to consist of two subspecies with disjunct ranges. The nominate race is found in southeastern Brazil, and also perhaps in northeast Argentina and east Paraguay, though with no records from these countries since 1977. 2,500 km separate the nearest known population of the nominate race from the area in central-western Bolivia where three specimens of the taxon known as P. f. boliviana were collected in 1845 and 1902.
Evidence presented by Hennessey in The Wilson Journal
(123(3):454–458, 2011) indicated that the Bolivian population should be treated as a separate species, Phibalura boliviana
. The plumage is distinctly different: boliviana
males have longer tails than flavirostris, and their body plumage is significantly less sexually dimorphic. The iris of boliviana is mustard yellow, distinct from the blood red iris of flavirostris
, and boliviana
has orange-yellow feet while those of flavirostris
are pink. Only one vocalisation type is recorded for flavirostris
, whereas at least five calls and a song are known for boliviana
, which vocalises significantly more often. The Brazilian flavirostris
has strong seasonal movements, whereas boliviana

The proposed common name proposed for the species comes from the indigenous Quechua language: “palka” meaning fork and “chupa” meaning tail.
“On first speaking with the people of Aten, their comment was that they did not know Palkachupa was so rare” says Bennett Hennessey. “Being so common in their village they assumed it was found everywhere.”
