DEAR JOAN: I have been hearing a weird bird call every night,
all night long, for a week or so. It sounds something like "eep"
every 10 seconds or so.  Recently this very bird flew onto a
branch of a redwood tree across from my deck, and I was able to
identify it as a young great horned owl.  Where are the parents?
How long does it take for it to become an adult and start
"hooting?"  Penny Wade   DEAR PENNY: What you are hearing is a
fledgling owl who still expects to be fed. For months now, mom
and dad have been bringing it food, but now that it has fledged
-- left the nest -- it needs to start hunting on its own.  A
juvenile great horned owl. A juvenile great horned owl. (Travis
Heying/Wichita Eagle)  When fledglings start in with their
"eeping," you'll often hear the parents hooting back. The male's
voice is deeper than the female's, and her calls usually will
end on a higher note. It would appear they are telling junior to
hush up and find his own dinner.  The nesting season for great
horned owls is in Ja
