Longevity in some Malagasy rainforest passerines

Abstract

Data on longevity is a prerequisite to understand the life-history strategies of a species. For Malagasy songbirds no information has been previously published. Therefore, we studied their longevity in a capture–recapture effort in a rainforest in eastern Madagascar (Maromizaha, Andasibe) between 2003 and 2016. We present first data on the longevity of 23 species of Malagasy songbirds. A female Dark Newtonia Newtonia amphichroa (Vangidae) and a Grey-crowned Greenbul Bernieria cinereiceps (Bernieridae) attained an age of at least 12 years, followed by two male Madagascar Brush Warblers Nesillas typica (Acrocephalidae), female Madagascar Bulbul Hypsipetes madagascariensis (Pycnonotidae) and Madagascar Drongo Dicrurus forficatus (Dicruridae) that attained at least 10 years. There was much variation within some taxonomic groups, longevity did not increase with the mass of a bird species and most insectivorous birds lived longer than granivorous ones.
