Fallow deer
A population of several thousand red deer inhabit the moors and hills. Fallow deer can be found in the southeast, and roe deer are common on low-lying ground. Otters are common around the coasts along Nave Island, and common and grey seals breed on Nave Island. Offshore, a variety of cetaceans are regularly recorded including minke whales, pilot whales, killer whales and bottle-nosed dolphins. The only snake on Islay is the adder and the common lizard is widespread although not commonly seen. The island supports a significant population of the marsh fritillary along with numerous other moths and butterflies. The mild climate supports a diversity of flora, typical of the Inner Hebrides.
