The black-bellied starling (Notopholia corusca) is a species of starling in the family Sturnidae, originally described by zoologist Alexander von Nordmann in 1835. It is found in Eswatini, Kenya, Mozambique, Somalia, South Africa, Tanzania, and Zimbabwe.
Their iris color changes by mood or behavior due to fluctuations in blood flow rates. Black-bellied (glossy) starling – Species text in The Atlas of Southern African Birds Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black-bellied Starling is recorded against all the birds logged in Zanzibar City (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
