Census counts were made in dry sclerophyll forest, and a clearing along a powerline,
at Black Mountain Reserve, A.C.T . on 156 days between March 1974 and April 1975.
There were seasonal changes in both species and numbers in each site. There were
more species and individual birds in the clearing than in the forest. Most of the forest
birds used the clearing and five additional species colonised it. Colonists were mainly
small passerines inhabiting dense undergrowth. Some species found in the clearing
would not have been recorded if there had not been adjacent forest. The enrichment
would almost certainly not apply to large tracts of cleared dry sclerophyll forest, nor
would it have occurred in this case but for the management policies of the Reserve
authorities.
