Abstract: Based on the bird surveys in blocks along Century Avenue, Pudong New District, Shanghai, this paper analyzes the niche demand and microhabitat selection, explores the preference of birds on the hard surface of buildings/structures as special microhabitat in high density urban areas. The results show that: 1) The tree canopy and herb surface provide main food and nest spatial niche, which are also verified by the analysis of microhabitat selection; 2) Vertical hard interfaces can also provide potential microhabitats for wild birds in the city, which could be used as a supplement to the existing biological habitat system; 3) Due to the demand of some wild birds to build their nests in urban building/structure holes, it is suggested to reserve certain holes in the design for building facade, sculpture and street furniture to provide potential space for the related birds' nest.
