Hi -
Lincoln County has more Red-shouldered Hawks, and they probably breed, but we
see a big surge in sightings each fall, with many first-fall birds setting up
winter home ranges (as well as some adults). So I think there is a pronounced
dispersal period for young birds each fall, and that while some clearly make it
through the winter, they do not stay at those spots through the spring. I
wonder if these are dispersers from nearby (undiscovered) breeding areas, or if
these isa big push north from California each fall?

Actually it remains a very infrequent species in Wash County.
Probably all my detections in October and November. Maybe
all young of the year. Lars
