New Zealand robins and tomtits resemble British robins, but the two groups are not closely related. The New Zealand species belong to the Australian–New Guinean family Petroicidae.
Robins and tomtits have large heads, short necks, round bodies and an upright stance. They have short bristles around the bill. Robins have long legs, and are larger than tomtits. All are insectivorous. The oldest known bird lived 16 years, but their life expectancy is three years. ~ Bernard
