The "Brain-fever Bird" gets a mention in one of Rudyard Kipling's Indian poems about freemasonry, written in the 1890s : -
"So man on man got talkin'
An' not a Brother stirred
Till morning waked the parrots
An that damn brain fever bird…"
Heirococcyx sparverioides - the Large Hawk Cuckoo is still alive and well both in India and south China and the places in between.
Here's one I photographed last week:

"Brain FEVER ! ....Brain FEVER !"
