Genetic evidence showed there is only one swift parrot population, so threats at different times and places can potentially act on the entire population. Although expert opinion has estimated the species population size as approximately 2,000 individuals, recent genetic evidence suggests this is overly optimistic, and that the (minimum) census size of the population may be lower than 300 individuals.
Genetic evidence indicates a single swift parrot population, meaning threats at different times and locations can impact the entire population. Although experts estimated the species' population size to be around 2,000 individuals, recent genetic findings suggest this estimate is too high, with the minimum census size potentially being lower than 300 individuals.
