Behaviors:
Cape thick-knees are monogamous birds and solitary nesters. The incubation period is 24 days, and the clutch size is usually 2 eggs. Both parents incubate, feed and protect the young.
Sometimes they are seen in organized flocks of 40-50 birds. On hot days, they lie on the ground with their feet outstretched behind them.
Males are quite vocal and aggressive. Both parents will defend the nest.
Adaptations:
Their coloring is good camouflage for their environment.
Defensive behavior can be an adaptation. To lure a predator away from the nest or young, one of the parents may flop helplessly on the ground, pretending to have a broken wing. After catching the predator’s attention, this parent lures the predator away. When the nest and young are out of harm’s way, the parent miraculously recovers and flies away unharmed, leaving behind a bewildered predator.
Special Interest:
This bird is also referred to as the spotted thick-knee
