Population Dynamics of Shorebirds,articular, midwinter counts over the whole of western Europe have given good indications of the year-to-year changes in the populations of several sandpiper (Scolopacidae) species breeding in discrete Arctic areas such as western Siberia or Greenland. These counts indicate fluctuations within ± 50%

The Evolution of Polyandry in Shorebirds,selection predicts competition among males, greater female than male parental investment, and more sexual promiscuity on the part of males than females (Darwin, 1871; Fisher, 1930; Orians, 1969; Trivers, 1972; Emlen and Oring, 1977). Polyandrous mating systems, particularly in extreme cases such as

Some species are resident and sedentary year-round, like the Shore Plover ., which exists in small numbers only on the Chatham Islands east of New Zealand; others undertake phenomenal migrat

Females are larger and more aggressive than males, parental care is performed only by males, and females copulate with several males whereas each male copulates with only one female.
