Is it really that surprising that after a journey from the Bering Sea back to 
Australia that a few birds die? Wrecks of Short-tailed Shearwaters (STSW) and 
other seabirds occur regularly all over the world.  In Australia, wrecks are 
common at this time of year because STSW adults returned at the end of 
September.  Juvenile wrecks occur in April/May after they fledge.  Some birds 
just aren't going to make it.  Given the breeding population is estimated to be 
between 23 -30 MILLION I don't think the numbers that have been reported will 
have any significant impact on the population.

Wrecked birds can be very useful to science.  Birds can be used in a number of 
different ways such as looking for effects of plastic ingestion, heavy metal 
contamination and staple isotope studies.  Numbers and timing of wrecks can 
also be used to infer migration.  Don't forget, all birds should be checked for 
leg bands.  STSW are the third most banded species in Australia (120,000 to
