Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: The wide variety of birds in Basse Casamance was noted by early explorers. While Basse Casamance National Park and Kalissaye Avifaunal Reserve have not been open for years due to the Casamance Conflict, Carabane has been found to be very conducive to ornithological observation. A study in 1998 discovered the following species on the island: African darter (Anhinga rufa), Goliath heron (Ardea goliath), palm-nut vulture (Gypohierax angolensis), black-tailed godwit (Limosa limosa), whimbrel (Numenius phaeopus), Eurasian curlew (Numenius arquata), Caspian tern (Sterna caspia), blue-spotted wood-dove (Turtur afer), red-eyed dove (Streptopelia semitorquata), white-rumped swift (Apus caffer), woodland kingfisher (Halcyon senegalensis), grey-backed camaroptera (Camaroptera brachyura), red-bellied paradise-flycatcher (Terpsiphone rufiventer), pied crow (Corvus albus), black-rumped waxbill (Estrilda troglodytres) and yellow-fronted canary (Serinus mozambicus).Fish are plentiful in the waters surrounding the island, where one may encounter trevallies (Carangidae), Giant African threadfins (Polydactylus quadrifilis), great barracudas (Sphyraena barracuda), or African red snappers (Lutjanus agennes). The mangroves are home to many crustaceans such as southern pink shrimp (Farfantepenaeus notialis), sand fiddler crabs (Uca pugilator), and molluscs. The shellfish population consists mostly of mangrove oysters (Crassostrea gasar), which cling to uncovered mangrove roots at low tide. The red-headed agama and monitor lizard make up the reptilian population of the island.
