Some herons & storks we photographed in East Africa
|
Black-headed Heron
the call is a loud croaking
builds a bulky stick nest and lays 2-4 egg
breeds in the wet season in colonies in trees, reedbeds or cliffs
common throughout much of Africa south of the Sahara, and Madagascar
|
|
Cattle Egret
will ride on the backs of large ruminants
nests in colonies, often with other wading birds
is of Old World origins, but has been a very successful coloniser
|
|
Goliath Heron
is the world's largest heron - wingspan of at least 7 ft (2 m)
in flight it is slow and rather ponderous - legs not held horizontally
hunts by standing, intently watching the water at its feet - spears prey
|
|
Grey Heron
call is a loud croaking "fraaank"
spears fish, frogs, small mammals and birds
waits motionless for prey, or slowly stalk its victim
generally solitary except when breeding - builds a bulky stick nest
|
|
Marabou Stork
one of the largest flying birds in the world
will eat just about any kind of animal, dead or alive
loves carrion & squirts excrement onto its own legs
rely on vultures to open tough outer hides then dig in with huge bills
establishing nesting territory they inflate gular sacks to repel intruders
|
|
Saddle-billed Stork
the saddle is the yellow patch
in flight, large bill droops - unusual appearance
is represented in an Ancient Egyptian hieroglyph
probably the tallest, but not the heaviest, of the storks
huge bird, typically 150 cm (5 feet) tall with a 270cm (9 feet) wingspan
|

Yellow-Billed Stork
generally seen in groups
quickest known muscular reflex
allows almost all food to be caught in water
> Feeding <

seized prey manipulated, wriggling, between mandibles
then swallowed (usually alive)
