Empty shells of the same species were foundhere and there under telegraph poles and along thefences. The explanation of this fact is found in thehabits of the commonest hawk of the region, the Ever- Lite in La Plata 233 glade Kite, as it is called in Florida {Roslrhamus socia-bilis), rather a rare bird in North America, but thecommonest of all the hawks in the meadow-lands aboutLa Plata. This bird has a very strongly curved beak;in fact its beak is more strongly curved than is the casein any other bird of the group to which it belongs. Thepurpose of this strong curvature of the beak is reali/xdwhen we learn that its staple food consists of the snailswhich it finds in the arroyos and shallow j)ools of thepampas, and which it extracts from their shells.
