Population numbers of the Aransas -Wood Buffalo Population (AWP) of whooping
cranes, number of whooping crane sightings on the Platte River, Nebraska, and the
number of sighting days (number of birds times number of days seen) on the Platte
River, 1950 to 2002, 134

(a) Number of whooping cranes sighted at Platte River divided by total number of
birds in Aransas -Wood Buffalo population (AWP) of whooping cranes in same year
(sightings ratio). (b) Number of whooping crane use -days (number of birds times
number of days birds spent on Platte River) divided by AWP in same year (use -
days ratio), 136

Sandy low bars along central Platte River serve as nesting areas for piping plovers
and interior least terns, 153

Sand mines along margin of central Platte River serve as nesting areas for piping
plovers and interior least terns, but not as suitable as sand masses in river, 154

Sandy shore of Lake McConaughy provides nesting areas for piping plovers and
interior least terns when the reservoir is low enough to expose beaches, 154
