White-browed Woodswallow

The White-browed Woodswallow, Artamus superciliosus, presents a striking figure in the Australian skies. This medium-sized passerine, measuring approximately 19 cm, is adorned with a distinctive white brow that elegantly contrasts its black head. The upper body is cloaked in a deep blue-grey, while the chestnut underbody adds a warm touch to its plumage. Males exhibit a slightly more vivid coloration compared to their female counterparts.

Identification Tips

To identify the White-browed Woodswallow, look for the characteristic white eyebrow feature above its dark head. The deep blue-grey of the upper body transitions to a rich chestnut below, with the males displaying a more pronounced hue. Their bifurcated tongue is a common trait among woodswallows.

Habitat

These birds are quite adaptable, inhabiting a variety of environments from the margins of rainforests and woodlands to inland and coastal scrubs. They can also be found gracing golf courses, vineyards, suburban streets, and even arid regions across Australia.

Distribution

The White-browed Woodswallow is a widespread resident throughout Australia, with notable populations in central New South Wales. They are known for their nomadic tendencies, often moving in large flocks that can number in the thousands.

Behaviour

Highly nomadic, these woodswallows travel in pairs or flocks, which can range from a hundred to thousands of individuals. Their movements across the Australian landscape are irregular, typically venturing north to the Northern Territory and central Queensland for the winter, and returning south in the spring for nesting. They are often seen in the company of Masked Woodswallows, Artamus personatus.

Song & Calls

The White-browed Woodswallow communicates with a 'tchip-tchip' call, reminiscent of the calls made by their Masked Woodswallow kin.

Breeding

Breeding season for these woodswallows spans from August to December, or opportunistically after rainfall. They construct their nests in a variety of locations, from shrubs and tree forks to hollow stumps and posts, using twigs, grass, and rootlets. Their eggs are white or grey, adorned with spots or blotches of brown-grey, and a typical clutch consists of 2 to 3 eggs.

Diet and Feeding

While nectar is on the menu when blossoms are available, the White-browed Woodswallow primarily feeds on insects, making the most of the abundant invertebrate fauna of Australia.

Conservation status

The White-browed Woodswallow is currently classified as Least Concern by the IUCN Red List, indicating a stable population without immediate threats to its survival.
