We studied prey availability and use by Harpy Eagle on six breeding territories on the low- and mid-Xingu River, between 2013 and 2015. We evaluated food resource availability using the environmental-surveys database from two methods: terrestrial surveys (RAPELD method) and fauna rescue\/flushing before vegetation suppression for the Belo Monte Hydroelectric Complex construction. Harpy Eagle diet was identified by prey remains sampled around six nest trees. Eighteen species of mammals, birds and reptiles comprised the prey items. Most prey species were sloths, primates and porcupines, which have arboreal habits and are found in forested areas, but two species, hoatzin and iguana, are usually associated with riverine habitats. The proportion of prey from each species predated on the nest best studied was different from estimated availability (\u03c72 = 54.23; df = 16; p &lt; 0.001), however there was a positive correlation (rs = 0.7; p &lt; 0.01) between prey species consumed and abundance available, where the predation was more on species more abundant. Continuous monitoring of the Harpy Eagle diet at these nests could evidence changes in the assemblage of prey species available for Harpy Eagles, due to changes in the seasonal flood pulse of the Xingu River to be caused by the operation of the hydroelectric dam, and changes in habitat features by forest reduction around breeding territories. We believe that it is important to consider the protection of remnants of forested areas in the landscape matrix surrounding the breeding territories to maintain the food resource availability and allow all pairs to successfully reproduce.<\/jats:p>","DOI":"10.1590\/1519-6984.00914bm","type":"journal-article","created":{"date-parts":[[2015,12,18]],"date-time":"2015-12-18T21:33:55Z","timestamp":1450474435000},"page":"181-189","source":"Crossref","is-referenced-by-count":16,"title":["Resource availability and diet in Harpy Eagle breeding territories on the Xingu River, Brazilian Amazon"],"prefix":"10.1590","volume":"75","author":[{"given":"FH.","family":"Aguiar-Silva","sequence":"first","affiliation":[{"name":"Instituto Nacional de Pesquisas da Amaz\u00f4nia, Brazil; Programa de Conserva\u00e7\u00e3o do Gavi\u00e3o-real, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TG.","family":"Junqueira","sequence":"additional","affiliation":[{"name":"Biota Projetos e Consultoria Ambiental Ltda., Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TM.","family":"Sanaiotti","sequence":"additional","affiliation":[{"name":"Programa de Conserva\u00e7\u00e3o do Gavi\u00e3o-real, Brazil; Instituto Nacional de Pesquisas da Amaz\u00f4nia, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"VY.","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Biota Projetos e Consultoria Ambiental Ltda., Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PVC.","family":"Mathias","sequence":"additional","affiliation":[{"name":"Biota Projetos e Consultoria Ambiental Ltda., Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CV.","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"Biota Projetos e Consultoria Ambiental Ltda., Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","author":"Aguiar-Silva FH","year":"2012"},{"key":"ref2","author":"AGUIAR-SILVA FH","year":"2013"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","first-page":"24","DOI":"10.3356\/JRR-13-00017.1","article-title":"Food habits of the Harpy Eagle, a top predator from the Amazonian rainforest canopy","volume":"48","author":"Aguiar-Silva FH","year":"2014","journal-title":"The Journal of Raptor Research"},{"key":"ref4","first-page":"22","author":"Aguiar-Silva FH","year":"2014"},{"key":"ref5","series-title":"Cen\u00e1rios para a Amaz\u00f4nia: clima, biodiversidade e uso da terra","first-page":"57","volume-title":"\u00c1reas de endemismo Bel\u00e9m e Xingu: configura\u00e7\u00e3o e espacializa\u00e7\u00e3o do uso da terra e da cobertura vegetal","author":"ALMEIDA AS","year":"2014"},{"key":"ref6","series-title":"Biology and conservation of the Harpy Eagle in Venezuela and Panam\u00e1","author":"\u00c1lvarez-Cordero E","year":"1996"},{"key":"ref7","first-page":"1","article-title":"Nuevo registro de nidificaci\u00f3n de la Harpia (Harpia harpyja) en la provincia de misiones y consideraciones sobre su conservaci\u00f3n","volume":"21","author":"ANFUSO J","year":"2008","journal-title":"N\u00f3tulas Faun\u00edsticas"},{"issue":"1","key":"ref8","doi-asserted-by":"crossref","first-page":"146","DOI":"10.1590\/S1415-47572008000100025","article-title":"Genomic resources for the conservation and management of the Harpy Eagle (Harpia harpyja, Falconiformes, Accipitridae)","volume":"31","author":"Banhos A","year":"2008","journal-title":"Genetics and Molecular Biology"},{"key":"ref9","series-title":"Projeto Prodes: programa de monitoramento da floresta amaz\u00f4nica brasileira por sat\u00e9lite","year":"2004"},{"key":"ref10","series-title":"Lei n\u00ba 9.985, de 18 de julho de 2000 que institui o sistema nacional de unidade de conserva\u00e7\u00e3o da natureza (SNUC).
