First description of the nest and egg of the stipple-throated antwren (epinecrophylla haematonota) from Peru

Abstract

The life histories of most Epinecrophylla antwrens are poorly known. I describe the first nest and egg of the Stipple-throated Antwren (E. haematonota), which was found in the southern lowland rainforest of Amazonian Peru. The closed and globular nest was located 0.33 m from the ground, and was laterally supported by palm fronds. The single egg was off-white and partially covered by dark magenta spotting. The nest and egg descriptions match other Epinecrophylla, but differ from Myrmotherula. The results support the split of Epinecrophylla from Myrmotherula.
