Twitcher's tip

A bower is NOT a nest - it is a male bird's courting alley. Nests, built by female birds, are in fact kept well away from bowers. A Spotted Bowerbird's nest is shown below.

Sightings

Spotted Bowerbirds came to our place 20 km South of Narrabri, NSW, mostly through the winter seasons. During the heat of summer they were not seen there in the years 2003-2006.

Only a few feathers of this Spotted Bowerbird's nuchal crest are pink - the rest is dark-grey; the last remainders of pink on its lores visible in the close-up view above indicate that this is a young bird

Breeding information

Breeding season: Sep - Jan Eggs: 1 - 2 Incubation period: 21 - 22 days Fledging age: ca. 21 days

Nest construction, incubation and care for the chicks is entirely the task of the female. The male is too busy with his bower and his attempts to attract as many females as possible to assist... Females keep their nests well away (at least 50 m) from bowers.

Nest

"bungobittah", "malunna" = Nest [Aboriginal]

Type: Basket Material: Twigs Height above ground: 2 - 15 m

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 38 x 28 mm Colour: Creamy, structured with brown streaks all over Shape: Tapered oval

Behaviour

Social behaviour: Territorial Mobility: Sedentary/roaming Elementary unit: Solitary

Male birds are sedentary, females are roaming.

While some other birds splash themselves wet when bathing, Spotted Bowerbirds fully immerse themselves in water.

We have noticed that, while normally they always skip, male Spotted Bowerbirds - when trying to impress a female and thereby craning their neck while displaying their nuchal crest - can, and do, in fact walk. We have not seen any Spotted Bowerbird walking on alternating feet in any other circumstances yet.

Bowers

Male Spotted Bowerbirds try to attract as many females to their territory, and thus their bower, as they can. It appears that male Spotted Bowerbirds hone their building skills based on experience (see "additional information" link below).

Food, Diet

Spotted Bowerbirds around our place have shown a taste for a varied diet - we have seen them stealing our mulberries, taking nectar from bottlebrush flowers, eating seeds of Kurrajong trees and cracking seeds of the White Cedar trees on the property. Below a view of another favourite type of food, the fruit of a Californian Peppertree.

Fruit of a Californian Peppertree; the red ones are ripe - we have seen Spotted Bowerbirds take these; since they did not appear in the bower as decoration, the birds will probably have eaten them

Another surprise came when we observed two birds "trim" our parsley plant, which finally explained why it seemed to never grow in size... Later, this turned out not to be so surprising (see below).
