Spring is in full flight - and so are the magpies.
Department of Environment and Conservation South West region wildlife officer Pia Courtis said she expected to see more complaints about swooping magpies as summer approached.
"Male magpies are territorial and may swoop at people if they think their nest or offspring are being threatened," Ms Courtis said.
"Tall trees in the suburbs provide the perfect environment for magpie nests and the best way to avoid being swooped is to find an alternative way of passing their breeding sites for the six to eight weeks that magpies usually defend their nest.
"We also encourage people to protect themselves by wearing a broad-brimmed hat and sunglasses to conceal their face and eyes."
DEC said a dangerous fauna licence could be issued to remove magpies deemed a "serious risk".
