First record of the buff-fronted owl, Aegolius harrisii - (Cassin, 1849CASSIN, J., 1849. Descriptions of new species of the genera Nyctale, Brehm., and Sycobius, Vieill: specimens of which are in the collection of the Academy of Natural Sciences of Philadelphia. Proceedings. Academy of Natural Sciences of Philadelphia, vol. 4, pp. 157-158.) (Aves - Strigidae) from the Brazilian state of Pernambuco

The genus Aegolius includes five species (Gill and Donsker, 2018GILL, F. and DONSKER D., 2018. IOC World Bird List, version 8.1. London: IOC.), but only the buff-fronted owl, Aegolius harrisii (Cassin, 1849CASSIN, J., 1849. Descriptions of new species of the genera Nyctale, Brehm., and Sycobius, Vieill: specimens of which are in the collection of the Academy of Natural Sciences of Philadelphia. Proceedings. Academy of Natural Sciences of Philadelphia, vol. 4, pp. 157-158.) occurs in Brazil (Piacentini et al., 2015PIACENTINI, V.Q., ALEIXO, A., AGNE, C.E., NACHTIGALL-MAURÍCIO, G., PACHECO, J.F., BRAVO, G.A., BRITO, G.R.R., NAKA, L.N., OLMOS, F. and POSSO, S., 2015. Lista comentada das aves do Brasil pelo Comitê Brasileiro de Registros Ornitológicos. Revista Brasileira de Ornitologia-Brazilian Journal of Ornithology, vol. 23, no. 2, pp. 90-298.). This species is widespread in central and eastern Brazil, being found throughout the Northeast, and also in the states of Rio Grande do Sul, Mato Grosso, Minas Gerais, Espírito Santo, Rio de Janeiro, Distrito Federal, São Paulo, Paraná, and Santa Catarina (Sick, 1997SICK, H., 1997. Ornitologia brasileira. Rio de Janeiro: Nova Fronteira.; Girão and Albano, 2010GIRÃO, W. and ALBANO, C., 2010. Sinopse da história, taxonomia, distribuição e biologia do caboré Aegolius harrisii (Cassin, 1849). Revista Brasileira de Ornitologia, vol. 18, no. 2, pp. 102-109.; Grantsau and Palo Junior, 2010GRANTSAU, R. and PALO JÚNIOR, P.J., 2010. Guia completo para identificação das aves do Brasil. São Carlos: Vento Verde.). In the Brazilian Northeast, A. harrisii has been recorded in three states that border Pernambuco – Alagoas (Sick 1997SICK, H., 1997. Ornitologia brasileira. Rio de Janeiro: Nova Fronteira.), Bahia (Antas et al., 1993ANTAS, P., CÂNDIDO-JÚNIOR, J.F., REINERT, B.L. and PINHEIRO, R.T., 1993. Lista das aves da fazenda Jatobá, Correntina, BA. In: Anais do III Congresso Brasileiro de Ornitologia-Resumos, 1993, Pelotas. Pelotas: Universidade Católica de Pelotas.; Lima and Castro, 1994LIMA, P. and CASTRO, J., 1994. Ocorrência e reprodução de Aegolius harrisii na Bahia. In: Resumos do IV Congresso Brasileiro de Ornitologia, 1994, Recife. Recife: UFRP.; Studer and Teixeira, 1994STUDER, A. and TEIXEIRA, D., 1994. Notes on the buff-fronted owl Aegolius harrisii in Brazil. Bulletin of the British Ornithologists’ Club, vol. 114, no. 1, pp. 62-63.; Girão and Albano, 2010GIRÃO, W. and ALBANO, C., 2010. Sinopse da história, taxonomia, distribuição e biologia do caboré Aegolius harrisii (Cassin, 1849). Revista Brasileira de Ornitologia, vol. 18, no. 2, pp. 102-109.), and Ceará (Girão and Albano, 2010GIRÃO, W. and ALBANO, C., 2010. Sinopse da história, taxonomia, distribuição e biologia do caboré Aegolius harrisii (Cassin, 1849). Revista Brasileira de Ornitologia, vol. 18, no. 2, pp. 102-109.). Sick (1997)SICK, H., 1997. Ornitologia brasileira. Rio de Janeiro: Nova Fronteira. referred to the expected presence of A. harrisii in Pernambuco, although this was not confirmed by documented evidence (Farias et al., 2008FARIAS, G.B., PEREIRA, G.A. and SILVA, W.A.G., 2008. Lista das aves de Pernambuco. Recife: Observadores de Aves de Pernambuco.). No subsequent records have been obtained of the occurrence of the species in the state.

Aegolius harrisii is of low priority for conservation (Stotz et al., 1996STOTZ, D.F., FITZPATRICK, J.W., PARKER III, T.A. and MOSKOVITS, D.K., 1996. Neotropical birds: ecology and conservation. Chicago: University of Chicago Press.) and medium priority for research, although it is classified as Near Threatened (Parker III et al., 1996PARKER III, T.A., STOTZ, D.F. and FITZPATRICK, J.F., 1996. Ecological and distributational data bases. Chicago: University of Chicago Press.; Holt et al., 1999HOLT, D., BERCKLEY, R., DEPPE, C., ENRÍQUEZ-ROCHA, P.L., PETERSEN, J.L., RANGEL-SALAZAR, J.L., SEGARS, K.P. and WOOD, K.L., 1999. Species accounts of Strigidae: Tamaulipas Pygmy-owl. In: J. DEL HOYO, A. ELLIOTT and J. SARGATAL, eds. Handbook of the birds of the world. Barcelona: Lynx Editions, vol. 5.), due to its sparse distribution and the lack of data on its populations. This emphasizes the need for research on the biology of the species and its geographic distribution. A. harrisii may face local threats from the widespread devastation of its natural habitats in the Atlantic Forest, and in particular the cloud forest enclaves, known locally as “Brejos de Altitude” (Viana, 1997VIANA, V., 1997. Dynamics and restoration of forest fragments in the Brazilian Atlantic moist forest. In: W.F. LAURANCE and R.O. BIERREGAARD, eds. Tropical forest remnants: ecology, management, and conservation of fragmented communities. New York: Chicago University Press, pp. 351-365.). It may have deleterious implications for remaining populations, due to the sensitivity of the species to habitat disturbance (Parker III et al., 1996PARKER III, T.A., STOTZ, D.F. and FITZPATRICK, J.F., 1996. Ecological and distributational data bases. Chicago: University of Chicago Press.).

The record of A. harrisii was obtained during fieldwork on the Fazenda Fojos (-8.892458°N, -36.558066°W) in one of the property’s largest forest fragments, known as Camapuã (22 ha), which is close to a fragment of 150 ha, located on the neighboring property. In May 2018, the mist-netting was extended to the nocturnal period, for the capture of bats. This resulted in the capture of a buff-fronted owl on May 20th 2018. This owl was subsequently released and photographed in its natural environment. The photographic record of the specimen (Figure 1) was deposited on the Wikiaves platform site (Oliveira, 2018OLIVEIRA, A.J., 2018 [viewed 4 April 2019]. [WA2978376,Aegolius harrisii(Cassin, 1849)].

), under catalog number WA2978376.

This record confirms the occurrence of the buff-fronted owl, Aegolius harrisii, in the Brazilian state of Pernambuco, which resolves a long-standing lacuna in the inventory of the state’s avian fauna. Reports of this type are important for providing basic ecological data on poorly-known species, in particular distribution records, which are essential for the development of effective environmental management strategies (Piacentini et al., 2006PIACENTINI, V.Q., GHIZONI-JUNIOR, I.R., AZEVEDO, M.A.G. and KIRWAN, G.M., 2006. Sobre a distribuição de aves em Santa Catarina, Brasil, parte I: registros relevantes para o Estado ou inéditos para a Ilha de Santa Catarina. Cotinga, vol. 26, pp. 25-31.; Godoi et al., 2012GODOI, M.N., MORANTE-FILHO, J., FAXINA, C., MODENA, E.S., PIVATTO, M.A.C., MANÇO, D.D.G., BOCCHESE, R., TERIBELE, R., MARTINS-ROSA, A.L. and STAVIS, V.K., 2012. Aves de rapina raras no estado de Mato Grosso do Sul, Brasil. Atualidades Ornitológicas, vol. 170, pp. 41-47.). Records of the rare, threatened or poorly-known species from data-poor areas are essential for the understanding of the local biota and the planning of effective conservation measures (Godoi et al., 2012GODOI, M.N., MORANTE-FILHO, J., FAXINA, C., MODENA, E.S., PIVATTO, M.A.C., MANÇO, D.D.G., BOCCHESE, R., TERIBELE, R., MARTINS-ROSA, A.L. and STAVIS, V.K., 2012. Aves de rapina raras no estado de Mato Grosso do Sul, Brasil. Atualidades Ornitológicas, vol. 170, pp. 41-47.).
