Habits and habitat of mountain plovers in California

Article Abstract:

Plovers are being pressured to use cultivated lands during the winter in the San Joaquin Valley, CA, and birds in relict populations at both the places relies on core areas of native habitat particularly in October and November. The study analyses the causes of the fast decline in continental populations of the mountain plover since 1970s. Plovers showed a liking for heavily grazed native rangelands and they used burned fields basically for night roosting. The alkali flats were the most favored but have almost died out.

Reuse of nesting scrapes by Kentish plovers

Article Abstract:

The reuse of nesting scrapes within breeding seasons by Kentish plovers (Charadrius alexandrinus) has been investigated. The study was conducted at Fuente de Piedra, an inland lake in southern Spain's Malaga province. The results showed that 5.6% of orignal nests were reused at least once. There was no difference in breeding success between the pairs that reused nets and those that did not. Kentis plovers may have reused nesting scrapes to save energy.

Foods of Mountain Plovers wintering in California

Article Abstract:

A study was conducted to investigate the foods of Mountain Plovers wintering at three difference locales in California. The birds were collected and evaluated for organochlorine residues and heavy metals in body tissues and were further treated collectively across areas. Results indicated differences in the diets of the Mountain Plovers, contradicting the perception that the birds specialized on coleopterans and orthopterans only.
