Abstract

Black-throated Blue Warblers (Dendroica caerulescens) are subject to nest predation by a variety of avian and mammalian species. I present evidence that slugs (Gastropoda: Mollusca) can also function as nest predators. On two occasions, slugs were observed feeding on 6–7 day-old nestling Black-throated Blue Warblers at Hubbard Brook Experimental Forest, New Hampshire, USA. This is apparently the first report documenting that slugs can function as avian nest predators.
