Quote #4
The Diricawl originated in Mauritius. A plump-bodied, fluffy- feathered, flightless bird, the Diricawl is remarkable for its method of escaping danger. It can vanish in a puff of feathers and reappear elsewhere. (12.3)
By the time Mr. Scamander was researching Fantastic Beasts, the Diricawl had long since vanished from Mauritius. But it must have reappeared elsewhere for him to confirm that it still existed. Does it live somewhere else on the island (far from prying Muggle eyes)? Or has is reappeared in another exotic location entirely? More exploration needs to be done.
Quote #5
In its native Fiji, a stretch of coast has been turned into a reservation for [the fire crab's] protection, not only against Muggles, who might be tempted by its valuable shell, but also against unscrupulous wizards, who use the shells as highly prized cauldrons. (14.4)
We can just imagine Mr. Scamander diving down off the coast of Fiji (perhaps using a Bubble-Head Charm) to observe the fire crab and its flaming bottom in its natural habitat.
Quote #6
The Kappa is a Japanese water demon that inhabits shallow ponds and rivers. Often said to look like a monkey with fish scales instead of fur, it has a hollow in the top of its head in which it carries water. (19.1)
If Mr. Scamander ran into a Kappa in Japan, he must have been able to trick the creature into bowing so that the water drained out of the top of its head. How do we know? He lived to tell the tale.
