Study the images below before
going out to watch the Peregrines
. You will find it easy to tell
the adults from the youngster. Khaos poses prettily in the top
photo - the rest are juveniles. The youngsters fledged within
the previous 3 - 6 days.

An adult has barring on its chest that runs head
to toe; a juvenile's barring is dark brown and runs vertically.
The juvenile's head isn't yet solid black, but does have the
distinctive black moustache and black stripe around its eye.
Adult feet are more colorful - the yellow stands out compared to
the pale feet of the juvenile. The other obvious difference is
the band at the bottom edge of the tail - it is much broader
than the light tips an adult has.
