Thanks, John, for the post. Relatively few reports come from that neck of
the woods given its proximity to the populated southern strip of BC. Just a
few comments:

> Screech Owl - one heard at Chilko Lodge

This is interesting. If Tweeters would recall, Riesen Reto posted a query
on here many months ago re. the likelihood of W. Screech-Owls in the dry
southern interior after he heard an owl call similar to a Screech Owl on a
trip he had made to a location near to Chilco Lake. Naturally we were
circumspect then, but testimony such as this points up the need for a
concerted field effort in the area. There could be an inland range
extension of this species into the moister ecosystems of the Chilcotin
plateau.

Clay-coloured sparrow populations have been mushrooming in central BC the
past several years so it is highly likely that the bird was indeed a
"Clay". Yet another species responding positively to the loss of forest
stands (they absolutely love clearcuts).

Yes, and the Chilko Lake fish are one of the bigger races, too. Not quite
the size of the Stuart Lake sockeye but close.

Great escapement numbers for Chinook for one spawning area for this day
and age.

Are eagles just lazy, or would there be an influx to the spawning area when
the sockeye carcasses have reached a certain level of putrefaction loved by
them?

You have to sell logs to keep the board members happy, John. The
major shareholders care nothing for *how* their pockets are lined. Public
pressure to mend the errant ways of the logging companies has had some
salutary affect the past few years what with the Forest Practices Act being
passed. However, it is still largely a cut-and-run type of operation in
the backwoods out of eyesight of the troubled greenies. How do you replant
a slope that has lost 50% of its soil load? Only continued pressure will
assure that they do not log every last merchantable tree off the slopes of
BC's mountains, coastal and interior.
