Short-tailed Shearwater

Ardenna tenuirostris

Appearance

Dark smoky brown body with a paler coloured throat, slender bill, light brown feet, narrow wings pointed at the tip, brown to grey-brown underwing colouration (some have whitish underwings), short rounded tail, body up to 43cm long, when flying black toes extend just past tail tip (Pizzey & Knight, 2007)

Behaviour

Nest on grass, leaves and in burrows underground. Lays one egg between November and December. Incubation for 52-55 days, chick remains in nest for 94 days. Occur in large flocks. Flocks travel offshore along undulating streams to feed on seas and coastlines in masses of Victoria. Feeding consists of fish and crustaceans (Museums Victoria, 2017;  Pizzey & Knight, 2007).

ClimateWatch Science Advisor

Climate change is expected to significantly impact migratory birds through timing of events like migration or breeding. Responses may include arriving at their breeding grounds earlier or later as global temperatures rise. They may also start appearing in new areas as climatic events alter preferred habitat, natural resources and migration routes.

Help scientists answer the question: "How are our animals, plants and ecosystems responding to climate change?"

 

When To Look

Migrating between August-November (Pizzey & Knight, 2007). Return to Australia usually in last week in September. 

October to April and early May for breeding. 

Note: ClimateWatch is looking for any changes in the timing of these events so remember to keep a lookout all year!

 

Where To Look

Within islands, coastlines and offshore undulating streams of South Australia, Western Australia, Victoria and Tasmania. More specifically from Recherche Island in WA to Bass Straight to Broughton in New South Wales. (Pizzey & Knight, 2007)

Note: ClimateWatch is looking for any changes outside of their known ranges so remember to keep a lookout beyond these regions too!
