Perhaps one third of the flock were juveniles with their very light plumage. One or two seemed to be starting the molt into darker plumage. Anyway, the question I have is since BHCO are parasitic nesters, when does the juvenile leave the host parents and rejoin the adult BHCO flock? As soon as it's fledged? Good birding, Eric _______________________________________________ Do not post admin requests to the list.
