Adults of both sexes have that white patch. This is a beautiful adult male.

Juvenile

Juveniles of both sexes are brown above, with buff edges to the feathers, rather than the bluish-grey of this adult male. Young males also lack the neat, rusty barring below; instead, having rather coarse, blotchy barring. They also have a pale supercilium, which is lacking in this adult. Finally, the intensity of the yellow iris increases with age - here it is very bright.
