Kara Gerdanlı Terzikuşu Orthotomus atrogularis

A brightly-colored tailorbird of lowland tropical forests, forest edges, and gardens. Long-billed with olive upperparts, pale underparts, and a rufous crown. Dark neck patch is only present in males and is unique if seen well but is sometimes concealed and difficult to see. Can be a shy species, staying deep within tangled vegetation; listen for its song, often given in duets, a series of trilled phrases. Also gives a high-pitched nasal “daydayday.” Common Tailorbird is similar but has a less extensive rufous crown and lacks yellow vent and black neck patch.
