Living as I do in a high-rise adjacent to Telopia Park (not for long, as I move in two weeks), I have seen or heard many flights of Corellas this autumn coming in the mornings to this location. Usually, they leave towards sunset. However, in the past two weeks there have been significant numbers that apparently stay in Telopia Park overnight, based on the calls emanating from the park, joining the resident Sulphur-Crested Cockatoos (SCC).
Tonight, between 8:30pm and 8:45pm, there were mass calls of Corellas in a flock. They were not evident on the skyline but clearly milling about in the vicinity of Telopia Park, leading to a presumption that they are roosting in the park now, instead of returning to Callum Brae as the normal direction of their flights suggest.
Are there any people observing at Callum Brae who are aware of a diminution in numbers there?
