Southern Ground Hornbills in Tarangire National Park, Tanzania.
sounds like thunder
The Southern Ground Hornbill (Bucorvus leadbeateri) is a creature of legend, standing as the largest and most striking species of hornbill in the world. Often referred to as the “Thunderbird” in various African cultures, this turkey-sized bird is known for its deep, booming call that sounds like distant thunder—a signal many believe to signal the arrival of the first summer rains. With their jet-black plumage, vivid red throat wattles, and remarkably long eyelashes, these "Feathered Reapers" are more than just a visual spectacle; they are elite predators of the savanna.

Southern Ground Hornbill Lifespan and Facts
While most birds have a short lifespan of two to five years, some species (particularly big seabirds and parrots) can live for fifty years or more. Ground hornbills fall into the latter group, with noted examples that have lived up to 70 years in captivity.
Do birds have eyelashes? A Unique feature of the Southern Ground Hornbill
Ground hornbills are one of very few birds that have eyelashes. It is believed that these modified feathers are helpful for keeping out dust as they forage for reptiles, frogs, insects, and small mammals on the ground. Here’s a second photo of the same pair (that I probably blew up larger than I should have). Note the visible eyelashes on the bird on the right.
Look closely at the bird on the right. Can you spot his eyelashes?
The southern Ground hornbill is vulnerable
Globally, this African bird is classed as vulnerable due to habitat loss, human persecution, and slow reproduction rates. Within South Africa itself, it is considered endangered.
Members of this group reach sexual maturity after six or seven years, but due to siblicide, raise only one chick in a breeding cycle that can take as long as three years.
I caught a view of these two birds perched on a dead tree in the Tarangire National Park in Tanzania.
