Guest Post: Monotonous Lark - The Marathon Croaker

Updated: Nov 14, 2019

Hello all


We're absolutely delighted to have, for the first time, a guest writer contributing a blog post on KrugerExplorer!


Respected ornithologist Duncan McKenzie has kindly written this piece on the monotonous lark - a species of bird that is more interesting than its name suggests! - as well as some great shots from his recent visit to Kruger National Park.


We're hoping it will be the first of many guest contributors to the KrugerExplorer blog and so please do contact us if you would be interested in writing something and have a great idea for a theme.


Many thanks for reading and to Duncan for his kind contribution!

MONOTONOUS LARK – THE MARATHON CROAKER

Duncan McKenzie


On a recent trip through central and northern Kruger we were regularly entertained by the comical Monotonous Larks that appeared to be calling from every second bush.

A male monotonous lark 'singing' with white throat extended.

These nomadic LBJs ("little brown jobs") are seasonal visitors to the Lowveld, arriving after the rains have produced a thick, lush layer of grass, breeding, and then vanishing for months or even years again.


Unlike many other birds, they have tiny breeding territories (up to two birds per hectare) so from one location it is possible to hear five or six birds calling at once. Males typically sing (if you can call it that!) from a perch, their white throats extending with each call and a short crest raised. They also frequently fly up to about ten metres high and float down to a perch with their wings held in a V-shape, all the while singing (again, not really musical!)


Their call can be likened to the short calls of distant frogs, a sort of bubbling croak. Repeated often. Like, every few seconds. All day. All night. Every day. Until the poor female relents and they raise a clutch together.


The oft-repeated call can be likened to “the-syrup-is-sweet” or, perhaps more aptly, “just-shut-up-and-eat”! They feed mostly on small invertebrates and seeds and build their nest in a domed grass cup on the ground level.
