Feeding Behavior

Hunts mostly by watching from low perch, then gliding down to catch prey in talons. Sometimes hunts actively along streams by moving from rock to rock at water's edge, and sometimes wades in shallow water, stirring up prey.

Eggs

1-2, sometimes 3. White to greenish-white, blotched with brown and lavender. Incubation is by both parents, with female incubating at night and much of day. Young: Female remains at nest almost constantly for first 2 weeks after eggs hatch, and for much of time thereafter. Male hunts and brings food to nest, female feeds it to young. Young leave nest after about 6-7 weeks, move to nearby trees; can fly well at about 10 weeks; adults continue feeding them for a further 5-6 weeks.
