There could be a few reasons for this, but maybe it's due to the difference
in timing of breeding between those species.  Great Horned Owls begin their
courtship very early, so they're very vocal from late fall through
mid-winter.  By now, most pairs have youngsters in their nests and do not
call as frequently.  Sometimes, only males can be heard giving their low
pitched, 4-note call when females are sitting on eggs or chicks.
Incubating or brooding females often make a quiet clucking sound in
response to the male hooting, but it can only be heard very close to the

Western Screech-Owls' courtship begins in late winter, and they nest in the
spring.  They're probably calling more frequently right now.  In general,
Great Horned and Western Screech-Owls are year-round residents and probably
don't go far once they've found a mate and a territory.
