The composition and diversity of spring migratory birds at 26 important ecological conservation stations in Shenyang were surveyed using linetransects and point counts from March 21 to May 9, 2014. In total, 94 bird species (19 855 individuals) belonging to 40 families and 16 orders were recorded. Of the 94 species, two were classified as class Ⅰ national protected birds in China and four were class Ⅱ national protected birds. Summer residents and passing migrants were the dominant species, accounting for 77.7%. The recorded species were composed of Palaearctic, Oriental and cosmopolitan species, and Palaearctic were the dominant species, accounting for 74.5%. There was a wide variety of bird ecotypes in the survey areas, of which, 36.2% were songbirds. The bird community composition and diversity showed evident spatial variations. Birds were most abundant in the reservoir wetlands. The species richness was the highest in the wetland parks, and the bird composition included 26 water birds and 19 songbirds. The avian diversity was the highest in the forest ecological system, where the composition was dominated by songbirds, such as great tit (Parus major
), and grey-capped greenfinch (Carduelis sinica
). The diversity of birds was low in the sandy habitats, where only 17 species were recorded. In addition, we also found some significant ecological conservation issues in the areas with a high degree of human disturbance, severe ecological damages, and homogeneity of habitat types. We recommend that ecological conservation and management of damaged protected lands in Shenyang should be enhanced to provide more diverse and suitable habitats for birds.
