| Description | Ondersoek is ingestel na aspekte van die anatomie en morfologie van kroonkiewiete (Vanellus coronatus) wat oor ’n tydperk van een jaar op die J.B.M. Hertzog - en B.J. Vorster-lughawe te Bloemfontein en Kimberley respektiewelik versamel is. Klaarblyklik word die verekleed van beide geslagte hoofsaaklik gedurende die somermaande venuwe. Afgesien van sommige snawelafmetings is alle standaardliggaamsafmetings van volwasse en onvolwasse mannetjies betekenisvol groter as dié van wyfies. Geen duidelike seisoenale patroon kon in die liggaams - en lewermassa van die voëls onderskei word nie. Seisoensvariasie in die sigbare vetinhoud van volwasse kroonkiewiete van beide geslagte hou waarskynlik met broeiaktiwiteite en die beskikbaarheid van voedsel verband. Aspects of the anatomy and morphology of crowned plovers (Vanellus coronatus) collected over a period of one year at the J.B.M. Hertzog (Bloemfontein) and B.J. Vorster (Kimberley) airports were investigated. The renewal of plumage in both sexes apparently takes place mainly during the summer months. Except for some bill dimensions, all standard body measurements of adult and immature males are significantly larger than those of females. No clear seasonal pattern could be distinguished in the body and liver mass of the birds. Seasonal variations in the visible fat content of adult crowned plovers of both sexes are probably related to breeding activities and the availability of food. | |
