This is an adult, lacking the narrow buff wing-bars of immatures. Song thrushes were introduced from England, and were widely released in New Zealand starting in 1867. They are now common in disturbed habitats such as parks and gardens. This race is indigenous to Great Britain and Western Europe. It averages darker and less gray than the nominate subspecies in Central Europe, but differences are slight. A darker race is described from the Outer Hebrides. Canon PowerShot SX50 HS.
