Interesting. What actually is each dot? Is it a year, a place? GBS, other data, etc. Is it measuring something about surveys in general?

Yes there is a positive statistical relationship between the reporting rate of the Grey Butcherbird and Noisy Miner but whether the change in reporting rates of both is due to the same or related factor (eg urban
expansion) or that one is dependent on the other (the presence of more Noisy Miners allows more Grey Butcherbirds to establish) cannot be determined from this data.
