BREEDING BIOLOGY OF SPUR-WINGED LAPWING (Vanellus spinosus L.) AT BOGAZKENT, ANTALYA/ TURKEY 2009-2011

摘要

The breeding biology of Spur-winged lapwing (Vanellus spinosus L.) was studied in Bogazkent/Antalya between 2009 and 2011. Population density, nest number, clutch size, hatchling number and habitat selection was determined. Besides birds were trapped and banded with metal and color rings and some morphological parameters as wing-, bill- and spur length were collected. Egg size was measured (width, length and weight). On the other hand, predation factors and their feeding preference were determined. Population consisted of 52 individuals in 2009, 60 individuals in 2010 and 72 in 2011. Nest numbers were 17 in 2009, 27 in 2010 and 38 in 2011. Incubation period was 23 days and the mean of clutch size was 3.6, total hatchling number was 23 juveniles in 2010 and 27 juveniles in 2011. Their nest preferences were mostly fields, grasslands and sand areas. 13 adults were banded in 2010 and 25 adults also in 2011. The predators of eggs and juveniles were mainly Hooded crow, dogs and fox. Their nourishment was generally crustacean and insect species, which live in the mud on the near surface.
