Light as a Feather by Angela Robertson-Buchanan

Light as a Feather explores the science of feathers, how they get their colour, the marvel of flight, and their uniqueness. A new direction of work for nature photographer Angela Robertson-Buchanan who has photographed intricate feathers with a macro lens and graphic designers Eggpicnic who have explored birds in flight. This exhibition is especially for BirdLife Australia's National bird week, with 20% of sales donated to them.

Regent Parrot Wing, Contour, Semiplume & Tail feathers.
The Regent Parrot has two separate populations separated by the Nullarbor Plain: one in the Mallee regions of eastern Australia, and the other in the Wheatbelt region of southern Western Australia. Eastern populations are endangered, while the western population is thought to be increasing.

The Science of Feathers

Each feather on a bird’s body is a perfected structure, they not only provide flight, but provide insulation, waterproofing, camouflage and display.

Semiplume Scarlet-chested Parrot Feather
Semiplumes are hidden beneath other feathers on the bird’s body and have a loose structure that helps the bird stay warm.
The Scarlet-chested Parrot, which inhabits arid and semi-arid parts of southern Australia, is one of our most poorly understood species of parrots. The reason for this is that they seldom occur regularly at any particular site. Instead, they briefly turn up here and there, and then disappear, seemingly without a trace. 
Their conservation status is rare in South Australia, Vulnerable in NSW and secure in Western Australia

Different types of feathers

Semiplume Feathers are hidden beneath other feathers on the bird’s body and have a loose structure that helps the bird stay warm.

Contour feathers are what you see covering the bird’s body. The interlocking colourful region is structured to help keep the bird dry. The bottom third of the feather is the downy section that traps heat.

Wing feathers have a branched structure that interlocks like Velcro to create a uniform windproof surface that allows lift in flight. The main wing feathers are typically asymmetrical with a shorter leading edge for improved aerodynamics

Tail feathers feature a branched structure that interlocks like Velcro to create a uniform surface helping birds to steer in flight.

Down Feather has a loosely branching structure which allows birds to trap body heat and stay warm, normally found beneath the semiplume feathers.

Rainbow Lorikeet Wing, Contour & Tail feathers.
The Rainbow Lorikeet occurs in coastal regions across northern and eastern Australia, with a local population in Perth (Western Australia) and Tasmania, initiated from aviary releases. In last year’s Australian Bird Count, the Rainbow Lorikeet was the most counted bird so made number 1!

Ibis Tail Feathers, study 1
Each feather marking is unique to each individual bird, a bit like our finger tips. Under analysis, scientists can tell how old the feather is (by unique stress lines and patterns, a bit like tree rings) and what environmental exposures they have been subjected to.
Due to habitat clearance, some Australian White Ibis populations have learnt to exploit artificial foods in urban environments and are becoming perceived as pests. However, although Australian White Ibises are becoming more common in some urban areas, their abundance is decreasing in their natural range.

Immature Male Superb Fairy Wren moulting into breeding plumage.
Male Fairy-wrens moult into their breeding plumage (blue tail, head, body) each breeding season. Immature males will moult into breeding plumage the first breeding season after hatching, but it will be incomplete and take 2/3 years to perfect. The tail feathers are an important feature of a Fairy-Wren as they are usually held upright and assist with balance when they hop and bounce! Tail feathers are what steers a bird in flight.
