Suppose that in the near future, the fish crow population in North America declines because of habitat destruction. Now that you have reviewed the large-scale distribution and abundance of the fish crow (see fig. 9.15 b ), devise a conservation plan for the species that includes establishing protected refuges for the species. Where would you locate the refuges How many refuges would you recommend

Figure 9.15 ( a ) Winter distribution of the American crow, Corvus brachyrynchos. ( b ) Winter distribution of the fish crow, C. ossifragus (data from Root 1988).
