Abstract
The present study deals with the observation of migratory birds on the coastal areas of Karachi (Hawkes Bay and Clifton) during the year 2001 — 2004. Different kinds of aquatic migratory birds (gull, terns, heron, egret, sandpiper) were observed during this period. These birds belong to 5 order, I I families and 49 species. In the Hawkes Bay area the seasonal abundance of migratory birds were more than that of Clifton. It could be concluded that every year the migration of birds vary in numbers and different environments produce pronounced effects on bird populations.
