This was the third year the 6-day small group birding tour ‘Highlights of South Australia’ was run by Southern Birding Services. This season, the tour was run twice (once in October and once in December). This trip report cover the December tour. The October tour had exactly the same itinerary, with the two main differences being that during the October tour a Scarlet-chested Parrot was seen at Gluepot, but no Eyrean Grasswrens were seen at Montecollina Bore. The December tour commenced on 10 December in Adelaide, South Australia, and finished there on 15 December. Places visited included the Adelaide Hills and woodlands, River Murray, Birds Australia’s Gluepot Reserve, the Flinders Ranges, the Strzelecki outback desert and coastal areas north of Adelaide. By visiting a variety of habitats the species list was maximized resulting in a total of 194 species, a new record for this tour, including some highly sought-after species.
