MAGUARI STORK NESTING: JUVENILE GROWTH AND BEHAVIOR

Maguari Stork (Ciconia maguari) Science Article 1

abstract

Although it has a wide range in tropical South America, the Maguari Stork (Ciconia maguari) is poorly known. In an 11-yr study of its breeding biology in the llanos ofVenezuela I found the mean clutch size for 3 yr to be 3.2 eggs. The young hatched synchronously at 29-32 days and usually made their first flight at 60-72 days. Data on egg sizes, weights, and a probable dump egg are given. The weight and growth of two siblings, plumage succession, and nestling and fledgling behaviors are described
