Ornitholog past studies focused on the natural environment, now they have a lot of studying birds in urban areas. In Java inhabited by 368 species of birds recorded settler and nomad 126 species of birds , but it is not known how many types of them which now lives in urban areas. Bird diversity in the city of Yogyakarta, which was founded in 1755 and now has a population of 388 627 inhabitants, is unknown. The research objective was to determine the diversity, the proportion of community based on the type of bird feed (guild) and bird species nest in the city of Yogyakarta. The study was conducted during the day in April-May 2013 in the 7 villages of 3 subdistricts in the city center Kraton, Gondomanan and Ngampilan. Data colection used Point of Abundance Index method, and analyzed by the Shannon Diversity Index - Wienner ; types of feed directly observed and are determined based on a review of literature and the proportion of bird communities based on guild were analyzed with the use of modified importance value index ; nest observed directly and analyzed descriptively. The results showed in Yogyakarta were found 28 species of birds covered in 11 familia with moderate levels of diversity (diversity index 2.2) and 5 types including protected status that is Anthresep malacensis, Nectarinia jugularis and Arachnothera longirostra (Fam.Nectariniidae), Alcedo atthis and Halcyon cyanoventris (Fam. Alcedinidae). Composition based on the guild type is graminivorous (46.58 %), nectarivorous
(46.51 %), nectrivoous (5.53 %), frugivorous (1.08 %), and 0.29 % piscivorous, and was found at least nine species of birds that nest in the city of Yogyakarta. Therefore, birds in the city of Yogyakarta is quite diverse and populated several protected species, it is necessary to research on biological properties, especially the origins, patterns of reproduction and structural adaptation and behavior.
