White-winged Chough Corcorax melanorhamphos |

Click on image for call
White-winged Choughs are cooperative birds with a complex social structure so are usually seen in groups (average group size of about eight). They forage for insects and small prey, normally in leaf litter in woodlands. They are fairly common around Black Mountain, Mount Ainslie, the Australian National University, and Canberra University. Incredibly, small groups are often seen foraging around office blocks in Civic. From a minimum in September, numbers build slowly to a peak in May before a more rapid decline. Numbers have been relatively stable over the period of the survey. Choughs build large mud nests and have an extended period of caring for nestlings and fledglings. Most choughs leave the suburbs in September to breed in larger reserve areas. As young fledge and families need a wider area to forage, they move back through the suburbs. Most breeding records are of dependent young from early October to late May. June, July and August are the only months with no recorded breeding activity. R=51. BR=28.
