Priorities for Future Research

Introduction

The Leaden Antwren is widely distributed and is fairly common across its range, although it occupies a restricted habitat on islands in large Amazonian rivers. Most aspects of its natural history are very poorly known. Almost all aspects of its reproductive biology are unknown, and there is little detailed information on its diet. There is no information on such topics as age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality and population density, and sexual behavior. There is little or no information available on responses by the Leaden Antwren to seasonal flooding of its island habitat. Finally, the phylogenetic relationships of this species are unresolved, although the available genetic evidence suggests that this interesting species is not a member of the genus Myrmotherula at all.
