Superb Fairy-Wren

Australian Birds Most at Risk from Cats (And What You Can Do)

Australia has some of the most extraordinary birds on Earth. Sulphur-crested cockatoos, rainbow lorikeets, superb fairy-wrens, kookaburras — species found nowhere else. And domestic cats are one of their biggest threats in suburban Australia.

Domestic cat outdoors — even well-fed pet cats hunt native birds

An estimated 377 million birds are killed by cats in Australia each year. Feral cats do the most damage in wild areas, but pet cats are a serious threat in the suburbs and towns where many native species live alongside us.

Here are the Australian birds most commonly caught by domestic cats — and what you can do to help.

Superb Fairy-Wren

These tiny, stunning birds are one of the most common cat victims. The males' brilliant blue plumage makes them iconic in Australian gardens, but their small size and habit of foraging low to the ground makes them extremely vulnerable to cats.

Noisy Miner & Honeyeaters

Honeyeaters are among Australia's most important pollinators. Noisy miners, New Holland honeyeaters, and eastern spinebills are common in suburban gardens where they feed on nectar-producing native plants. Their focus on feeding makes them vulnerable to ambush.

Rainbow Lorikeet

Lorikeets are fast and loud in flight, but when they're feeding on flowers or drinking from bird baths, they're surprisingly vulnerable. Their bright colours and noisy behaviour also draw attention — including from cats watching from below.

Australian Magpie

Young Australian magpies learning to forage on lawns are particularly at risk. Adult Australian magpies are large enough to sometimes fend off a cat, but juveniles and fledglings are easy targets during the spring and summer months when they're learning to fly and feed independently.

Willie Wagtail

These charismatic little birds spend much of their time on the ground or on low perches, hawking insects. Their fearless personality — they'll happily forage near humans — unfortunately extends to being unbothered by nearby cats until it's too late.

Silvereye

Silvereyes are small, social birds that travel in flocks through suburban gardens. Their size makes them easy prey, and a cat that finds a silvereye flock can catch multiple birds.

Fledglings — The Most Vulnerable

Regardless of species, fledgling season (September to January) is when cats do the most damage. Young birds that have just left the nest can't fly well, spend time on or near the ground, and haven't learned to recognise predators yet.

This is the most critical time to have your cat wearing a CatBib. Even a few weeks of protection during peak fledgling season can save many young birds.

It's Not Just Birds

Cats also catch: - Bandicoots — quenda (southern brown bandicoot) are common in Perth gardens and are vulnerable to cat predation, especially at dusk - Skinks and geckos — small reptiles are easy targets - Frogs — particularly during wet weather when they're active and exposed

The Murdoch University study found that CatBibs reduce small mammal catches by 45% and reptile/frog catches by 33%.

What You Can Do

1. Fit a CatBib

The CatBib is university-tested to reduce predation of birds by 81%. It's the most effective single thing you can do without changing your cat's lifestyle. From $25 AUD with free shipping.

2. Keep Your Cat In During Peak Risk Times

Dawn and dusk are peak hunting hours. During fledgling season (Sep-Jan), keeping your cat in during the morning is especially valuable — that's when young birds are most active and vulnerable.

3. Create Bird-Safe Zones in Your Garden

  • Place bird baths and feeders at least 2 metres high and away from hiding spots
  • Use prickly plants around the base of bird-attracting trees
  • Keep ground-level cover trimmed where cats might stalk

4. Support Local Wildlife Organisations

  • BirdLife Australia runs conservation programs
  • Your local council may have cat management resources
  • Report feral cat sightings to your local wildlife authority

The Bigger Picture

Cat owners aren't the enemy here. Most of us love animals — that's why we have cats in the first place. But the reality is that even well-fed, well-loved domestic cats hunt. It's instinct, not hunger.

The good news is that solutions like the CatBib let you be a responsible pet owner AND a friend to native wildlife. You don't have to choose between your cat's happiness and the local birds.
