The Grey-winged Cotinga Tijuca condita, previously known from a single specimen collected in 1942, was rediscovered near the type-locality in the coastal hill ranges of Rio de Janeiro state, south-eastern Brazil, in November 1980. Fieldwork at two sites in November/December 1980 and November 1981 revealed the presence of 10 individuals: one calling male and one female in cloud-forest at 1,320 m in the Serra do Tinguá; and six calling males, one female and one unsexed bird in cloud-forest at 1,830-2,000 m in the Serra dos Órgãos. Two females were netted, and two calling males were seen well in the field. The plumage of calling males resembled that of females, but was brighter with more grey on the face. The voice was described as an explosive sooee-wheee. The calling posture was similar to that of pihas Lipaugus, and there was no indication of any lekking behaviour. The species appears to have a very restricted distribution, but there is no indication that it is under threat at the present time.

O cotingídeo Tijuca condita, previamente conhecido de um único indivíduo coletado em 1942, foi redescoberto próximo a sua localidade tipo nas montanhas da costa do estado do Rio de Janeiro, no sudeste do Brasil, em novembro de 1980. Observações no campo em duas localidades em novembro/dezembro 1980 e novembro 1981 revelaram a presença de 10 indivíduos: um macho cantando e uma fêmea em uma floresta de neblina a 1,320 m na Serra do Tinguá; seis machos, uma fêmea e um individuo de sexo não determinado em uma floresta de neblina a 1,830–2,000 m na Serra dos Órgãos. Duas fêmeas foram capturadas em rede e dois machos foram bem observados no campo. A plumagem dos machos assemelha-se a das fêmeas, contudo mais brilhante e acinzentado na face. O canto foi descrito como um explosivo sooee-wheee. A postura de canto foi semelhante à de outros cotingídeos Lipaugus e não há indícios de comportamento de leque. A espécie parece ter uma distribuição muito restrita, mas não ha indícios de que essa espécie esteja ameaçada no momento.
