Burhinus grallarius
Variety of Bush Stone-curlew calls, still awaiting classification into call types. Although this is a resident species in many areas, migration is not out of the question, so definitive records of flying birds are of interest.
Perfect match to spectrograms of this call, which is also given in the daytime.
High confidence since this is a well-known vocalisation.
Remember that other shorebirds could potentially give similar noises, so keep alert especially on sequences of the more excitable call notes.
Project detections: 1160 annotations; 43 nights; recorded in January, March, April, July, September, October, November; most recent detection 29 Apr 2026.
