Map of Hooded Cranes distribution and migration routes.
Data from The cranes: status survey and conservation action plan [9], Threatened birds of Asia [10], and field work in recent years.
Figure 2.
Map of the study area and habitat.
This map was created in ArcGIS 10.1 by combining the visual interpretation of a remote sensing image (pixel size resolution of 2×2 m, downloaded from Google Maps; image taken in September, 2010) and our field observations.
