I am not familiar with any locations there, but one approach is to use ebird. Go to
http://ebird.org/ebird/places and enter the place name. Click on "bar charts" and scan down the monthly/weekly markers for what is present. For October, there are decent chances for pine grosbeak, gray jay, boreal chickadee, lapland longspur, Am. pipit, woodpeckers, etc. Click on the map button next to each species name to get some ideas for places where they have been reported.
