Summary: We provide the first descriptions of the nest, eggs, and nestling of Coopmans"™s Elaenia Elaenia brachyptera  from the foothills of northeastern Ecuador. We describe 7 active nests, 10 eggs, and 1 mid-aged nestling. Nests are open cups, woven of flexible, pale fibers and rootlets, externally decorated with various loosely-arranged materials. They are placed in small saplings within flat, rocky, river floodplains. Nest placement and architecture make nests difficult to distinguish from naturally accumulated materials left behind by periodic flooding. Clutch size ranged from 1-2 eggs and we estimate incubation to last 15-16 days. Eggs are typical of the genus, buffy to creamy white with small cinnamon and lavender spots and blotches concentrated at the larger end. We also provide a comprehensive review of published literature on the nests, eggs, and breeding ecology for the genus Elaenia, including studies on 30 of the 46 currently recognized taxa.
