Currawongs are a strong curious bird that will eat almost anything. They nest in thick forest and usually lay 3 eggs in spring or summer. The Pied Currawong can form large flocks in late summer and winter and may have a large communal roost.
There are 3 species of currawong in Australia:
- Pied Currawong (Strepera graculina) found down the eastern seaboard to Victoria
- Black Currawong (Strepera fuliginosa) found only in Tasmania
- Grey Currawong (Strepera versicolor) Grey Currawong found mainly in the southern half of Australia and Tasmania
The Grey Currawong is rarely seen in large numbers.
All species are omnivorous and they will raid other bird’s nests for eggs or young at every opportunity. They are fond of grapes and fruit and thus are a pest to farmers in some areas, usually where there is timber or forest nearby.
Currawongs seem to be far less sensitive than some other pest bird species, for example the crow. This “dull witted” attitude makes the currawong quite hard to deter at times, especially in late summer when they’re very hungry due to a shortage of natural foods. Possibly currawongs do a service to vignerons and orchardists by eating nestling silver-eyes in the spring, however few farmers are very understanding when their crop is being destroyed later in the season.
Currawong reaction to Bird Gard’s sounds can differ from area to area. Whilst the AVA is effective in one district, in another we have to use the Electronic Scarecrow (ESC) and Bird and Bat Control (BBC) combined to move them. Possibly the overlapping of different species may have something to do with this. The Super Pro #2 with a currawong distress call is also effective in some areas. The multiple-sound Bird X-8 has given excellent results and the sheer power of the Pro Amp is the most effective of all.
