Hi - these are freebies.  I'm in Buffalo, I'll mail them to you in the US or Canada, don't worry about reimbursing the postage....ok, if guilt wracks your soul you can reimburse the postage but really don't sweat it.

1) "the 8th revision of the Checklist and seasonal status of the birds of algonquin park."  I have checked off 13 birds in the booklet. 2018.
2) "algonquin provincial park management plan."  It is about 75 pages long, very cool book from 1998, and has a large zoning Map in an envelope glued to the back cover.  This is a real A-Z book on the park.
3) "fishing in algonquin park." I paid the princely sum of $1.50 in 1985.  The park used to have these interesting booklets on a variety of topics, kind of a series - mammals, amphibians, trees, and of course this one on fish.
