Fun Facts
This bird breeds north of the equator, but spends the rest of the year in eastern and southern parts of Africa.
Storks often defecate on their own legs in order to maintain their body temperature through the process of evaporative cooling.
Storks have little or no webbing between the toes and their tibia is bare of feathers.
This bird is rarely seen in groups of less than ten birds. They are sometimes spotted in huge flocks of up to 10,000 individuals.
Abdim's storks are often seen in and around large swarms of locusts, gorging on the insects.
Ecology and Conservation
As with many storks and vultures, Abdim's storks are known to feed on carrion. They also break through thick hides of large, deceased mammals with their powerful beak. This helps to speed up the decomposition process and allows weaker scavengers to gain access to the carcass. In addition, they are important predators, frequently seen standing on termite mounds ingesting swarming insects. In turn, these birds may become prey for large carnivores.
Abdim's storks have little fear of humans and are not usually in danger from hunting because of a local superstition that they are "bringers of rain." Other local traditions include building nests for the birds on rooftops hoping the storks will bring good luck.
Potential threats include habitat loss due to urban and agricultural development and loss of primary food sources (as in locusts) that may be eliminated by pesticides in order to protect crops.
