An adult Rose-breasted Cockatoo in Wamboin, Australia

A cockatoo is any of the 21 species belonging to the bird family Cacatuidae. Along with the Psittacoidea (true parrots) and the Strigopoidea (large New Zealand parrots), they make up the parrot order Psittaciformes. Cockatoos are instantly recognisable by their showy crests and curved bills. Their plumage is generally less colourful than that of other parrots, being mainly white, grey, or black, and often with coloured features in the crest, cheeks, or tail. On average they are larger than other parrots. Cockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly when ground-feeding. Cockatoos are monogamous and nest in tree hollows. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable nesting hollows after large mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests. Cockatoos are popular birds in aviculture, but their needs are difficult to cater for. The Cockatiel is the cockatoo species that is easiest to care for and is by far the most frequently kept in captivity. (more...)

    Mespelbrunn Castle

    The western front of Mespelbrunn Castle, a moated castle in the town of Mespelbrunn, between Frankfurt and Würzburg, Germany. It dates to 1427, when the family who lived in that location began to build it as defense against brigands who lived in the nearby Spessart mountains. Only the round tower (center-right) remains from that time; the remainder was constructed in the mid-1500s.
