Breeding Bird Censuses: An evaluation of Four Methods for use in Sclerophyll Forest
|Author(s):||Shields and Recher|
Four methods were used to census birds in forest and woodland near Bombala on the Soulhern Tablelands of New South Wales. None was completely satisfactory, but a modified strip transect procedure provided repeatable estimates of the relativeabundance ol most species.The most accurateestimatesof the abundanceot individualspecies were obtained by combining territory mapping wilh colour banding of individuals and Intensrvesearches for nests. Mist netting wa, necessary to colour band birds, but by itsel was nol particularlyuselul as a census procedure.Mist netting was also the most time consumingmelhodusedand requiredthe grealestnumberof people.Mappng and nest searches were also time consumlng. but could be done by one person. Transect counts took lhe least effort and can be regarded as the most eflicient use ol resources where an estimateof relativeabundancesis all that is required.
