I recently noticed that there was a Karoo Thrush painstakingly building a nest in the fork of a tree in our garden. My interest grew, watching as this hard-working bird carried in twigs, wet grass and even tissue paper to help line the bowl-shaped nest, followed by a thin layer of mud to smooth things off. What was interesting was that the female did all the work while the male just watched on.
A couple of days later I noticed that two light blue eggs with brown speckles had been laid in the nest. The male and female shared incubating duties until I pulled my cameras out as I noticed two tiny, pink chicks had hatched, their hearts beating wildly. I captured some of this special footage as they shuffled around trying to find a comfortable place to rest and grow, as the female brought in copious amounts of earthworms and insects to nourish them. I was astonished by the rate at which the chicks grew and started sprouting feather splines which quickly turned into proper feathers. Their wings seemed to take shape at an incredible rate of knots.
Each week for three weeks I filmed the chicks, until they were so big that there was no room left for them in the nest. Then something surprising happened. As I was filming them fighting for real estate in their cramped environment, one of them stood up and launched itself up and out of the nest and landed in the foliage below. Our Golden Retriever, Storm, darted into the undergrowth and gently picked up the half grown chick in his mouth and brought it to me. It was amazing to see his natural instincts kick in, handing me the little chick as gently as he had plucked it from the undergrowth.
I tried putting the chick back into the nest a couple of times, to no avail, before both chicks decided they had had enough and jumped out of the nest onto the nearest part of the tree fork, clinging on with their well developed, clawed feet. That’s when I learned something fascinating. This is the typical way that Karoo Thrush chicks behave. Even though they have wing feathers and short tail feathers, they remain perched on the available branches in a tree for a month or so, while the mother continues to feed them until they are big enough to fly and start feeding themselves. It was the first time I had observed this behaviour in any bird.
Here’s the short video that I created so you can see some of this action for yourself:
All ended well as we now have four resident Karoo Thrushes in our garden. Another interesting thing is the similarity of species such as the Karoo, Olive and Kurrichane Thrush. It was an enlightening experience right here at home as opposed to the many dramatic sightings we have enjoyed in the South African bushveld, as well as the Central Kalahari desert, Okavango Delta and the Masai Mara in Kenya.
