            Glossary: Helpful Words Relating to Shorebirds & Wetlands 
             
			  
             
            Adaptation -- a characteristic or behavior that helps an organism survive in its environment.  Long pointed wings and long bills are important shorebird adaptations. 
			
  
			Biodiversity -- the variety of life.  Biodiversity can be considered at many levels such as the gene, species, population, community, and habitat levels. 
			
  
			Breeding ground -- the place where a bird lays its eggs and raises its young. 
			
  
			Breeding range -- the geographical area in which a bird lays its eggs and raises its young. 
			
  
			Cheet -- the sound a shorebird makes when calling. 
			
  
			Ecosystem -- a network of plants and animals that live together and depend on each other for survival. 
			
  
			Endangered -- a species or ecosystem reduced in size so that it is vulnerable to extinction. 
			
  
			Estuary -- a partly enclosed bay where salty ocean water is mixed with freshwater. 
			
  
			Field marks -- special characteristics that help identify one bird from another. 
			
  
			Flyway -- route used by migratory birds between breeding (summer) and non-breeding (winter) grounds. 
			
  
			Food chain -- a series of living things in which each member feeds on the one before and is in time eaten by the one after. 
			
  
			Food web -- a complex network of many food chains. 
			
  
			Habitat -- an environment of a particular kind, such as the tundra, pampas, or estuary. 
			
  
			Invertebrates -- animals without backbones. 
			
  
			Migration -- seasonal movements of a species, usually from non-breeding areas and back again, often with intermediate stops for feeding and resting. 
			
  
			Morphology -- what an organism physically looks like.
			
  
			Molt -- the periodical shedding and replacing of feathers. 
			
  
			Mudflat -- a major foraging zone for shorebirds along the edges of the bay.  Shorebirds use their bills to probe in the mud for clams, worms, and other animals. 
			
  
			Neotropical -- an adjective used to describe birds that winter in Central and South America. 
			
  
			Neotropical bird -- a bird that migrates seasonally between North America and the migratory tropics of Central and South America. 
			
  
			Nonbreeding ground -- the region where a bird goes to feed, rest, molt (replace feathers), and prepare for the next breeding season. 
			
  
			Non-breeding range -- the geographical area in which a bird lives during the part of the year when it is not breeding or migrating. 
			
  
			Ornithologist -- a scientist who studies birds. 
			
  
			Plumage -- a bird's coat of feathers. 
			
  
			Population -- the number of animals of the same type, usually the same species, that live in a given area. 
			
  
			Potholes -- small, waterlogged depressions. 
			
  
			Predator -- an animal that lives by killing and consuming other animals. 
			
  
			Preen -- to clean and repair feathers.  During resting and feeding breaks birds use staging ares to preen their feather which should be in perfect condition to function efficiently during flight. 
			
  
			Prevailing -- to be frequent; predominant. 
			
  
			Range -- the region throughout which an organism occurs. 
			
  
			Raptor -- a bird of prey. 
			
  
			Shorebirds -- birds that typically have long legs for wading in the mud and long pointed wings for migration.  They include sandpipers, plovers, oystercatchers, snipes, and stilts, among others. 
			
  
			Staging area -- an important area for shorebirds along their migration path. These areas provide food and a place to rest and condition (preen) their feathers. 
			
  
			Stopover -- a place to briefly stop to rest and eat while undertaking a journey. 
			
  
			Tundra -- a treeless plain of the arctic and subarctic regions. 
			
  
			Watershed -- an area where water from precipitation (snow, rain, etc.) drains into a particular body of water (stream, pond, river, bay, etc.) 
			
  
			Wetland -- low land covered with water at least part of the year.   Examples include marshes, swamps, potholes, bogs, mud flats, river deltas, and floodplains. 
			
  
			Wintering grounds (also known as "non-breeding ground)--a region where shorebirds go to feed, rest, molt and prepare for the next breeding season.
