My girlfriend does Murrelet surveys for an environmental consulting
company. This is the final week of the season for them. As for being
able to find nests by organizing a "search effort," well, I don't
think it works that way. Finding nests *is* a major priority, and its
still nearly impossible. They already climb many, many trees, have
four surveyors surveying at least 20 stands, and found no nests this
year. I read in a book recently that as of 1991 (horribly out of date, I
know) only three murrelet nests had been found *ever* on the Olympic
Peninsula. Surely, more are found in most years, but it's still, as Don
says, just a handful, and that's not likely to change. Using documented
nests from the past year as the only acceptable criterion for Marbled
Murrelet nesting in a given stand makes no sense. If you want to know
where murrelets nest, you have to use behavior, not nests as such, to
decide.
