Summary
Over a 12 day period, from the 24th July 2000 to the 4th August 2000, the avifauna of Minziro Forest Reserve was surveyed using observations, point counts, sound recording and 36,417 net-metre-hours. A total of 365 birds were caught and processed of which 59 were different species. In addition to this, species lists from previous ornithological visits to Minziro Forest Reserve in December 1984 (Baker & Hirslund, 1987), July 1987 (Baker unpublished), November 1993 (Baker & Baker, 1994) and October 1998 (Moyer, 1999) have been included (appendix II).
In total 245 species have been recorded in Minziro Forest Reserve, of which 96 (39%) are forest dependant specialists (FF) and a further 7 are considered forest edge (Fe) species. The remaining 142 species are forest non-dependant, many of these wanders. Of these 96 forest specialists, 52 are biome restricted, the remaining 44 being widespread forest species with scattered distributions due to habitat preference. Of the 365 birds processed, 7 were re-captures from the 1987 visit, adding providing valuable data what is known about these species ecology and longevity. Minziro Forest Reserve qualifies as an important bird area (IBA) due to the presence of Blue Swallow.
