The display of Gallinago stricklandii is described; the ecology and distribution of Uropsalis segmentata, Aeronautes andecolus, Leptasthenura yanacensis, Asthenes pudibunda, Xolmis rufipennis, Oreopsar bolivianus, Oreomanes fraseri, Idiopsar brachyurus, and Compsospiza garleppi are outlined; the feeding behaviour of Chalcostigma olivaceum is described; the nests of Leptasthenura yanacensis, Schizoeaca harterti, Ampelion rubrocristatus, and Phrygilus plebejus are described (those of the first three species apparently for the first time). The species of Furnariidae that are known to breed with incompletely pneumatized skull are listed.
