观察细节
One adult on nest in Holm Oak, with two nearly fledged young nearby. It isn't clear if these young are from the observed nest, but probably not as there is another nest near where the chicks are (but not seen by me). A third chicks was seen by others, apparently frlying from the Holm Oak towards the river. The other two chicks were squabbling intermittently, giving loud rasping squawks. One was exercising its wings. Photos show that its primary feather are not yet fully grown (pin stage 4?). At other times, chicks could be heard yapping (see sound recording), but again it isn't clear if these were the same chicks or a separate brood.
