观察细节
One immature and one adult type observed perched together on small bush at eastern edge of sewage ponds. Later flew across to bush to east of ponds. Much calling to one another (sound recorded). Photo of adult bird in this checklist: https://ebird.org/checklist/S155155685. Immature bird looks essentially like a juvenile except that some of the outer secondaries seem to be an older generation than the rest, lacking white tips and browner colour. Would be good to follow up on moult strategy of this species to establish what could produce this. Being mobbed by Meve's Starlings
