|Parana Antwren Stymphalornis acutirostris
(aka Marsh Antwren)
|Biritiba-Mirim, São Paulo, Brazil
I have included this species as Parana Antwren Stymphalornis acutirostris although it seems likely to be described as a new species. The Parana Antwren itself was described as recently as 1995 by Bornschein, Reinert and Teixera and is restricted to a small area on the coast of Paraná and Santa Catarina in south-east Brazil. Not unnaturally, Birdlife International classify it as Endangered.
|I managed to get a few photos of this bird but the habitat of typha marsh and the skulking habits of the bird made it difficult to get a good photo. Photo 1 is of the female and photo 2 is of the male. They look like a Formicivora antwren and some authorities believe it may well belong to that genus.
The discover of this new population / new species took place in February 2005. The press release from the University of São Paulo is here.
My translation into English of this press release is as follows:
Immediately the discoverer of the bird, the biologist, Luís Fábio Silveira of the University of São Paulo, together with his team, did everything possible to capture as many individuals as they could and release them in areas with similar vegetation, typha (cattails) marshland. "It is the first time in South America that this procedure, called re-location, has been used for insect-eating passeriforms", explained the scientist.
Since there is almost no literature on it, the procedure required special care. "We will monitor all the transferred populations for a year to ensure that they have adapted well to their new habitats." Silveira kept both IBAMA and the São Paulo Water and Electricity Department informed and they both followed and supported the project.
In total 72 individuals were captured (35 males and 37 females), all transferred to 12 nearby localities with similar ecosystems, giving priority to protected areas. Silveira states that the approach, although a bit drastic, had to be taken because some characteristics of the species indicated that its population was very small. "It is restricted to a habitat that is not very common in the region."
In parallel, another population of the species was located by the biologist Dante Buzetti in the region between Mogi das Cruzes and Arujá, near to the locality where it was first discovered. However, since the area did not present immediate risks, the creatures did not need to be relocated.
With precautions for the preservation of the birds taken it is hoped that the re-location of them will be successful and that the project will provide valuable information for future conservation programmes. The discovery of the birds was announced officially on 5th May 2005 by IBAMA who intend to include it in its list of endangered species."
