This is another difficult-to-photograph bird, the Grauer's warbler. Not only is it shy, it also lives in dense undergrowth and thickets in humid montane forests. It is placed in the family Cettia. This warbler lives in montane forests and forages in the undergrowth and lower treetops for small insects and invertebrates. It uses its fine, slender bill to pluck prey from leaves, vines and branches. Breeding pairs build cup-shaped nests of plant fibers, moss and spider webs. These nests are usually hidden low in dense vegetation and provide protection from predators. Both parents share responsibility, incubating the eggs and feeding the young until they are ready to fly. Although reclusive, the Grauer's warbler plays an important role in the montane forest ecosystem as an insectivore and occasional seed disperser. Unfortunately, its habitat is facing increasing threats from deforestation, agricultural expansion and human impact.
