Records of unusual bird species in Western Paraná State, Brazil

There is currently a lack of studies on other micro-regions of western Paraná apart from the Iguaçu National Park. Thus, ornithological knowledge of this region remains with knowledge gaps. Here we present records of unusual bird species in Paraná, obtained during development of different studies. Sporophila palustris, globally critically endangered, was recorded on 04 November 2016 in an area with fruiting Guinea grass Megathyrsus maximus (Jacq.) on the Universidade Tecnológica Federal do Paraná campus, Santa Helena municipality. We observed and photographed one male, which failed to be found on following days; the individual was among hundreds of S. caerulescens. In migratory movement, it is expected the species will be registered again during its return to Cerrado. The species had only two other records for the state. In the same municipality, on 16 February 2017, we heard a couple of Campylorhynchus turdinus which, a few days later, were photographed in sparse trees in the center of the city. It was known from Foz do Iguaçu municipality. In Palotina municipality, 100 km northeast of Santa Helena, we found an individual of Campylorhamphus trochilirostris of unknown sex, which had crashed into a glass window on the Universidade Federal do Paraná campus on 25 February 2017. This species is known from five other localities within the state. These records contribute to the knowledge of the occurrence of endangered species, and in the border of this state with Mato Grosso do Sul state (Brazil) and Paraguay.
