Texas Eastman Mason Lake (Iron Bridge) for waders, shorebirds, waterfowl and migrants. When we make our trips here we look for waders (egrets, herons, ibis, spoonbills) along with returning waterfowl, migrating shorebirds (sandpipers, plovers) and migrating land birds that are passing through. Watch for trips to this site later in the year. No set dates yet.
