May 22, 2015 – Grey Warbler or Riroriro (Gerygone igata)
Requested by: schmias
One of the smallest birds in New Zealand, Grey Warblers are found throughout most of the country. They eat insects, including beetles, moths, and caterpillars, picking them from tree trunks and branches, or hovering to pluck them from leaves. Their nests are hanging domes with an entrance on the side. Shining Cuckoos are a common brood parasite of Grey Warblers, replacing a warbler egg with one of their own. Because of their loud call and habit of foraging in dense foliage, they are often more easily identified by sound than by sight.
