Nesting, predation and nidoparasitismo Cacicus cela colonies (Birds: Icteridae) in the eastern Amazon, Amapá, Brazil. The Yellow-rumped Cacique, Cacicus cela, is an exclusively Neotropical Icteridae that occurs throughout the Amazon region. It inhabits humid tropical forests, including gallery forests. It is common in canopies and forest edges, river banks and clearing. The objective of this study was to describe the nesting, predation and nest parasitism in colonies of Cacicus cela in the Curiau Protection Area (00°14’17”N and 51°07’46”W).. We used to record the colonies point counts (through sight contact) and method sit-and-wait. We identified and monitored eight colonies of C. cela located close to temporary and permanent ponds and forest edges. All colonies were associated with insects of the order Hymenoptera. The periods of breeding varied in each colony, but the largest breeding range was from December 2007 to February 2008. The nests were built with palm leaves Astrocaryum aculeatum Meyer, Cocos nucifera L. and Euterpe oleracea Mart. We observed predation of colonies by Pseudastur albicollis. We identified four species of the family Tyranidae (Legatus leucophaius, Myiodynastes maculatus, Pitangus sulphuratus and Myiozetetes similis) using the nests of C. cela.
