Habitat & Geographic Range

Coastal wattle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (13 countries), Asia (Israel), Europe (4 countries), and North America (United States).

Cocos Cuckoo

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coastal wattle

Coastal wattle (Acacia cyclops) is a dense, fast-growing shrub in the family Fabaceae, native to the southwestern and southern coastal regions of Western Australia, from Shark Bay south to the Nullarbor Plain. It grows on coastal dunes, sandy scrubland, and limestone substrates near the sea, where it tolerates salt spray, wind, and summer drought. Coastal wattle produces distinctive circular seeds with bright red arillate coatings, making them highly attractive to birds. Although valued in its native range for coastal stabilisation and revegetation, the species has become highly invasive in southern Africa, particularly South Africa, where it was introduced for dune stabilisation in the 19th century and has since spread extensively across the Cape Floristic Region, displacing native fynbos vegetation. It is listed among the 100 worst invasive species globally by the IUCN Invasive Species Specialist Group. In Australia, it is assessed as Least Concern. Management of invasive populations in South Africa involves mechanical removal and biological control efforts aimed at protecting the critically threatened fynbos biome.

Cocos Cuckoo

The Cocos Cuckoo (Coccyzus ferrugineus) is a medium-sized bird in the family Cuculidae, endemic to Cocos Island, a remote volcanic island in the eastern Pacific Ocean approximately 550 kilometres southwest of the Costa Rican coast. This island-restricted species is closely related to mainland cuckoos in the genus Coccyzus and represents a classic example of insular endemism. Adults display rufous-brown upperparts, a pale buffy underside, and a moderately long tail with white tail-tip spots on the dark outer feathers. The species inhabits the dense tropical forest that covers much of Cocos Island, foraging in the mid-canopy for caterpillars, insects, and small lizards. As with other cuckoos, Cocos Cuckoos are often cryptic and detected more readily by their calls than by direct observation. The species is classified as Vulnerable by the IUCN due to its severely restricted range on a single island of approximately 24 square kilometres, making any localised disturbance potentially significant. Threats include introduced mammals—particularly feral pigs and cats—that degrade forest structure and prey on nesting birds. Cocos Island is a protected national park and UNESCO World Heritage Site, offering some measure of safeguard, but continued monitoring of invasive species management is essential. Population estimates remain uncertain, but the bird appears to be a common resident within the island's forested interior.
