The speckled warbler (Pyrrholaemus sagittatus) is a small bird found only in eastern Australia. It belongs to the family called Acanthizidae. These birds love to live in temperate forests, which are forests with mild climates.

About the Speckled Warbler's Name
The speckled warbler was first described in 1801 by an English doctor and bird expert named John Latham.
Scientists first thought this bird was related to scrubwrens. Later, they placed it in its own group. Now, thanks to new studies, we know it's closely related to another bird called the redthroat. They both belong to the group Pyrrholaemus.
The name Pyrrholaemus comes from ancient Greek words. Pyrrhos means 'flame-coloured' or 'red', and laimos means 'throat'. The second part of its scientific name, sagittatus, is Latin for 'shot with arrows'. This refers to the bird's chest, which has many streaks that look like arrow marks.
People also call this bird by other names, like blood tit, chocolate-bird, little fieldwren, and speckled jack.
What Does the Speckled Warbler Look Like?
The speckled warbler is a small bird that usually stays on the ground. It is about 11.5 to 12.5 centimetres (4.5 to 4.9 in) long. That's about the length of your hand! It weighs around 13.5 grams (0.48 oz), which is very light.
Its face is off-white, with brownish streaks near its ears. The top of its head is brown with small white spots, making it look "speckled." It has brown eyes, a dark grey-brown beak, and pinkish-brown legs.
Male speckled warblers have a black line above their eyes. Females have a reddish-brown line there instead. The feathers on their back are grey-brown with darker streaks. Their tail is dark brown with a black band and white tips. They usually hold their tail flat.
The bird's belly and chest are yellowish-white and have many black streaks. Young speckled warblers look a lot like the females, but the spots on their head are not as clear.
Where Do Speckled Warblers Live?
You can find the speckled warbler in southeastern Australia. They are spread out in different areas.
In Queensland, they live southeast of a line from Mackay to Charleville. They are more common in the far southeast of the state.
In New South Wales, they are found in places like the New England Tablelands and the South West Slopes. They also live west near the Pilliga Scrub and Griffith. Eastwards, they reach the Hunter Valley. They are quite common in the Australian Capital Territory.
In Victoria, these birds live in a wide area. This includes parks like Chiltern Box-Ironbark and Warby-Ovens National Parks. They are also found near Bendigo, the Brisbane Ranges, and You Yangs. They can be seen as far west as Balmoral, near the Grampians.
Speckled warblers prefer open eucalyptus woodlands. They like areas with rocky valleys, grassy patches, fallen logs, and not too many thick bushes.
How Speckled Warblers Behave
The speckled warbler is usually a quiet bird. Its speckled feathers help it blend in with its surroundings, making it hard to spot.
If something scares it, it will make a harsh, grating sound. Then, it flies to a branch to watch. Soon after, it usually returns to the ground to look for food.
Its song is soft, gentle, and musical. It also includes sharp whistles, a bit like the western gerygone (Gerygone fusca). This bird is also good at copying the calls of other birds!
Like the redthroat (Pyrrholaemus brunneus), the speckled warbler makes a special whirring sound with its wings when it flies.
Reproduction and Life Cycle
Speckled warblers usually breed from August to January. They build a dome-shaped nest with an opening on the side. They often place their nest in a small dip in the ground. You might find it near the bottom of a tree, in a thick bush, or among fallen branches.
The nest is made loosely from dried grass, pieces of bark, and moss. It often has soft feathers and fur inside to make it cozy. The nest looks a lot like the leaves and twigs around it, which helps to hide it.
A female speckled warbler usually lays 3 or 4 eggs. Each egg is about 19 by 16 millimetres (0.75 in × 0.63 in) in size. The eggs are a reddish-chocolate color, and they are darker at the wider end.
The female bird sits on the eggs to keep them warm for 17 to 20 days. After the eggs hatch, she also keeps the baby birds warm. Both the mother and the main male bird feed the young ones for 15 to 19 days.
Sometimes, other birds lay their eggs in the speckled warbler's nest. These are called brood parasites. Two examples are the fan-tailed cuckoo (Cacomantis flabelliformis) and the black-eared cuckoo (Chrysococcyx osculans).
What Speckled Warblers Eat
Speckled warblers find most of their food on the ground. They often forage with other bird species. You might see them with birds like the buff-rumped thornbill (Acanthiza reguloides) or the eastern yellow robin (Eopsaltria australis).
They mainly eat insects. Sometimes, they will also eat seeds. Their favorite foods include beetles, wasps, and winged ants. They also eat caterpillars and grasshoppers.
Conservation Status
Even though there are many speckled warblers (around 400,000), their numbers seem to be going down in some areas.
Some things that threaten them include:
- Land clearing: When people clear land, it removes their homes.
- Invasive weeds: New plants can take over their habitat.
- More predators: With less cover, they are easier targets for animals that hunt them.
- Over-grazing: Too many animals eating grass can damage their habitat.
- Salinization: Too much salt in the soil can harm plants they rely on.
- Drought and fire: Natural events like long dry periods and bushfires also pose threats.
In 2000, the speckled warbler's status on the IUCN Red List changed from "near threatened" to "least concern." This means scientists found it was more common than they thought. In 2016, it was still listed as "least concern."
The Australian government's main wildlife protection law, the Environment Protection and Biodiversity Conservation Act 1999, does not list the speckled warbler as threatened.
However, in New South Wales, it is listed as "vulnerable" under their Threatened Species Conservation Act 1995. In Victoria, it is listed as "threatened" under the Flora and Fauna Guarantee Act (1988). It is also listed as "vulnerable" on Victoria's 2007 list of threatened animals.
