A brood of four nestling Marsh Harriers
Circus aeruginosus hatched over approximately
seven days. When the three older nestlings were banded, the fourth and
youngest was one quarter of the weight of the next older nestling. The youngest
nestling was killed and eaten by its siblings during a period of food shortage. One
female and one male nestling fledged when 46 and 43 days old respectively. Evidence
for double clutching in Swamp Harriers is critically reviewed.
