When this bird suddenly swished past me, I almost dismissed it as another black bird until I had glimpses of whites. It was a Square-tailed Drongo-cuckoo, a young one too going by its plumage.
I was pretty sure it must have a scent of its prey somewhere in the dense foliage to cause it to zoom in so suddenly, and voila, it was on target!
A hairy grub small enough for it to down in one gulp!
A tell-tale sign of a tiny hair in its beak told of a meal just finished.
