Family
Artamidae
Genus
Artamus
Species
cynopterus
Threats/Control Methods - Regional
The key woodland habitat area for this species in the ACT region is currently considered an Endangered Ecological Community. Land clearing for urban development and agriculture is the greatest contributor to this problem. The invasion into these areas by introduced weeds, grazing and predation by feral and uncontrolled domestic animals are also key threats.
Threats/Control Methods - Local
Habitat simplification by 'tidying-up' forest areas within and nearby the suburbs will limit the areas that are favourable to this species, as will free roaming domestic Cats (Felis catus).
Local/Urban Actions
Dog owners should always keep their pets on a leash and cat owners can prevent their pets preying on the species by creating a stimulating indoor environment and by installing a cat run or enclosure. Collecting firewood from nature reserves or national parks should not be undertaken, as this will impact on the important foraging and nesting resources.

Australia
Conservation (Pet/Pest) Status - Regional

Conservation (Pet/Pest) Status - National
Secure, not listed under the EPBC Act 1999. They are classified as declining across the wheat-sheep belt of NSW.
LSCCES Population
11 sightings were made at the National Museum of Australia.
Associated vegetation community
The Dusky Woodswallow is a predominately a woodland bird, however it is also found in dry open forests or in larger vegetation patches around farms or along roads.
Limiting Resources
This species is limited to areas where there is a complex vegetation structure that includes mature trees, thick shrubs and good ground cover and fallen logs. It also relies on areas away from predation by feral or domestic animals.
Breeding
This species breeds in Canberra's surrounding woodland areas in the summer, with activities at the nest beginning from mid-October to late November. The nest is an untidy shallow cup of twigs, constructed on a tree fork, in a tree cavity or on a stump, from 1-20 metres off the ground. The nest's interior is neatly lined and holds 3-4 cream and brown speckled eggs. Eggs hatch after about 16 days incubation and are fed by both parents and sometimes the young birds from previous years. Dependant young are visible during December and January, having left the nest after 20 days.
Behaviour
This bird if very social and is likely to be spotted perching on powerlines or fences in pairs, small groups or large breeding colonies. It travels in large flocks, gliding and soaring with some quick wingbeats. Upon landing, the Dusky Woodswallow wags its tail. It is seen throughout the Canberra region in highest numbers during late summer and autumn, before migrating north for the winter.
Functional Group
Food Species
The Dusky Woodswallow prefers to eat a wide range of insects, however it will also drink nectar.
Predators
Domestic or feral Dogs (Canis familiaris) and Cats (Felis catus) may predate this species.
Interesting Fact
Dusky Woodswallows nest close together, forming a 'neighbourhood watch' and joining to defend one others' nests.
