We investigated bird habitat relationships in extensive eucalypt forest in the Blue Mountains, New South Wales, in 1986–87, assessing the importance of fire regime variables compared with other habitat variables. Our study sites encompassed a wide range of postfire ages, fire frequencies and fire severity, but we found no major bird community differences corresponding to differences in fire regime. The more common forest bird species appeared well adapted to fire regime variation in the 1980s. Tree canopy height was a far greater influence, with more species and more birds in taller forests (interpreted as a result of higher soil fertility leading to higher productivity of bird foods and greater structural complexity in taller forests). Other trends were fewer birds where there was a rainforest understorey under the eucalypts (reflecting the general scarcity of rainforest birds in the Blue Mountains), and more birds where nectar-rich flowers were more abundant (reflecting the abundance of nectarivorous birds in the Blue Mountains, especially over winter). The climate has changed since the 1980s and fires threaten to become much more severe, extensive and frequent. How these changes will impact on forest birds, and what management responses are required, is a critical area for further study.

We evaluated the abundance and distribution of low-elevation forest birds on windward Hawai'i Island during August 1993-February 1994, and present evidence of changes in the species composition of the forest bird community since 1979. Endemic Hawaiian birds occurred in native-dominated forests as low as 120 m elevation. Non-native species were detected at all survey locations. We observed non-native Saffron Finch Sicalis flaveola, previously unrecorded in Puna. Variable circular plot surveys of Kahauale'a Natural Area Reserve indicated the disappearance of two native species ('I'iwi Vestiaria coccinea and 'O'u Psittitostra psittacea), and two non-native additions (Red-billed Leiothrix Leiothrix lutea and Kalij Pheasant Lophura leucomelana) to the study area since the Hawai'i Forest Bird Survey conducted in 1979. We present evidence that native 'Elepaio Chasiempsis sandwichensis has experienced a decrease in population density and an elevational range contraction since 1979. Surveys indicate Puna's forest bird community has had increasing aliens and declining native species since 1979. The persistence of some native bird species within the range of avian disease vectors such as Culex quinquefasciatus in forests below 1,000 m elevation presents an important enigma that requires additional study.
