and Argentina gathered to present findings and participate in birding events. The Lower Rio Grande Valley (Starr, Hidalgo, Cameron and Willacy counties) provides habitat supporting about 520 resident, migratory and rare bird species, almost half of the 1114 recorded occurring in the USA as a whole. The presence of many tropical bird species encourages birders to visit in large numbers. Regional ecotourism that includes birding generated (as of ca. 2010) more than $300 million in local yearly revenue (Woosnam et al. 2011; Leslie 2016). We review the articles resulting from this first meeting in the USA and place them in contexts of taphonomy, hunting and domestication, and prehistoric and historic bird use.
