Bridled Tern killed by ticks.

["Greg & Val Clancy" <>]

There are approximately 75 species of ticks in Australia so the ticks on 
seabirds may be a specific species or number of species.  It has also been 
stated that sick animals are prone to become tick infested as they lack the 
strength to fully groom themselves.  This makes it hard to determine if the 
weakness is due to the tick or a pre-existing illness which may be 
exacerbated by the tick.
