Sure made me realize the bargain we get for a $15 annual membership in the Audubon Society of Missouri.
Perks include the quarterly, The Bluebird; Mobirds.org., the ASM website with many aspects, including CACHE and SPARKS that are beginning to show very well where to find what when; spring and fall meetings featuring birding opportunities with birders from around the state; i.d. workshops, special birding day/weekends; etc.
