Australasian robin

The Australasian robins are a group of small, colorful birds that belong to the family Petroicidae. This family has 51 different species spread across 19 groups, and they all live in Australasia — a region that includes New Guinea, Australia, New Zealand, and many Pacific Islands as far east as Samoa. Though they share the word "robin" in their name, these birds are not closely related to the European robin found in Europe, north Africa, and western Asia, which belongs to a different family called Muscicapidae. Instead, Australasian robins have their own unique traits and behaviors that make them special to the areas where they live.

Characteristics

Most Australasian robins have a compact body with a large, rounded head, a short, straight bill, and rounded wingtips. They live in many types of wooded areas, from cold mountain forests to tropical rainforests, mangroves, and dry scrublands. These birds mainly eat insects, though some also eat seeds. They hunt by perching and then quickly jumping to catch their food.

These birds often stay in long-term pairs and live in small family groups. Some family members help take care of the young birds. Nests are shaped like cups and are usually built by the female in the fork of a tree or shrub. Many birds add moss, bark, or lichen to hide their nests, making them hard to find even when they are in plain sight.

Taxonomy and systematics

The Australasian robin family was first introduced in 1888 by an English scientist named Alfred Newton. Though named after true robins, these birds were once grouped with flycatchers and later with whistlers before getting their own family name, Petroicidae.

This family belongs to a larger group of birds called Passerides, which also includes several other bird families. It is closely related to families like the Rail-babbler, Rockjumper, and Rockfowl.

Classification

Scientists have studied these birds and grouped them into families based on their traits. There are 51 different types of Australasian robins spread across 16 groups and 6 families.

Some of the groups include:

• Eopsaltriinae which has birds like the black-throated robin
• Drymodinae with just three species
• Microecinae including the torrent flyrobin and yellow-bellied flyrobin
• Petroicinae featuring the garnet robin and 14 other species
