Nilgai because the name means blue horse?
*Explodes into 1,000,000 pieces*
I'm not sure that was a clue. I think he actually exploded.

As for kiang's riddle...... the reference to a "son of Sabrosa" almost certainly refers to Ferdinand Magellan, who came from this province of Portugal. The reference to nectar would tend to rule out the most obvious taxon which is named for this explorer, the Magellanic Penguin, but certainly fits with the Magellan Birdwing (Troides magellanus), a species of butterfly. I haven't a clue whether or not this taxon is *at* Bronx, but it's worth a try.
As such, my guess is Magellan Birdwing.
