Quacking Frog

Crinia georgiana

Appearance

  • Colour:Markings on the upper body can vary from pale grey to brown or red often with an elaborate pattern.  There are bright red patches around the groin
  • Tadpoles: Golden colour with a transparent tail.
  • Distinctive feature: red, yellow or gold eyelids. Males have muscular front limbs, while females have slender front limbs.
  • Size: Males 1.9 – 4.4cm. Females 2.8 – 4.1cm

Behaviour

  • Call:.Sounds like a short, loud duck “quack”
  • Diet:Mainly insects although mites, snails, earthworms, spiders and other small animals are consumed. 
  • Movement:.Move to breeding areas from adjacent forest. Females only enter the breeding chorus for 1-2 nights.
  • Breeding:.Occurs from July to October on cold nights.  Sometimes, several males will embrace the female for fertilization. Females lay between 90 – 300 eggs which are released in about 10 minutes.  The eggs are large and separate and often laid in shallow depressions in seepages or in roadside ditches.  Tadpoles can be trapped in the depressions until the breeding site is flooded.

What to Observe

  • Calling
  • Courting/mating 
  • Multiple mating (comment in the Notes section if there is more than one male)
  • The appearance of eggs.

ClimateWatch Science Advisor

  • We expect frogs to start calling and laying eggs earlier in the year as a result of climate change warming the Earth.
  • They may also start appearing in new areas as warmer temperatures enable them to live in environments that were previously too cold for them.

When To Look

July to October

Where To Look

  • South West Australia
  • From Gingin in the north, inland to Dumbleyung and east to Cape Le Grande.  Can also be found on Mondrain Island
  • Coastal plains and forests with marshy areas, seeps and shallow bogs.  Often found in shallow water near granite outcrops.
  • Look and listen around areas where temporary water is abundant.

  1. What Else?

    This frog can be distinguished from other species of Crinia by gold or red on the eye combined with a red or golden groin.

  1. Did You Know?

    The genus Crinia is polymorphic which means there is great variation in skin colour and texture.

    Sometimes plant material can be found in frog stomachs, but this is only because their prey was resting on a plant and they ate it accidentally.

    In a drying pond tadpoles will accelerate their metamorphosis.
