The Texas Ornithological Society (TOS) has been working hard to make membership more attractive. Brad Lirette, the Membership Committee chair, has been pulling out all the stops to improve the value of TOS membership (in the interests of disclosure, I am a life member of TOS).
Recently, it was announced that TOS members could get their subscription to Birds of North America for $25 a year instead of $42 (of course, that happened right after I renewed this year--but next year will come around quickly enough). Also TOS members can also get 30% off books published by the Texas A&M University Press (and we've already established that one cannot have too many bird books!)
Thanks, Brad and TOS!
