Birds of Australia - various types of nests
|"bungobittah", "malunna" = nest [Aboriginal]|
Birds in Australia (and elsewhere) build nests of various types. Here our attempt to describe the commonly used nest types.
There are a few basic rules, although often there are exceptions, too. Passerine birds use mostly basket nests. Many aquatic bird species (all of which are non-passerines) are ground-nesting, with most species using scrapes or bowls. Most parrots and cockatoos use hollows (but there are some notable exceptions here, too).
Types of nests
|Basket||Commonly called "cup" or "bowl" nests; mostly made of interwoven sticks, twigs, grass and/or roots; usually lined with soft material, such as e.g. feathers|
|Mud nest||One particular type of bowl-shaped nest, made from mud, often with an inner lining made of plant-based materials and/or feathers|
|Scrape/bowl||Slightly indented or even flat area on the ground cleared of debris, often no materials are used to line or further camouflage the nest; many species use stones/rocks to create a ring around the scrape, creating a bowl|
|Hollow||Cavities dug out of suitable material; in some cases this material can be very hard|
|Tunnel||Particularly deep cavities dug out of suitable material; sometimes, but not always, dug into (near-)vertical banks|
|Mound||Heaps of organic material used for slow incubation by means of heat created by fermentation|
|Tree fork||Just a bare fork, otherwise no nest|
|No nest at all||Some bird species actually do not HAVE nests...|
Note that birds not only nest in colonies (of either one or more than one species), but that some bird species favour the proximity of others for protection. There is a separate page describing bird species nesting in clusters.
