Abstract
Following guidance issued within the Avian Inventory and Monitoring in National Parks of the Gulf Coast Network: Gulf Coast Network Avian Monitoring Plan, 40 point locations were established and monitored within San Antonio Missions National Historical Park. During three breeding seasons (May – Jun) and winters (Dec – Feb) between 2010 and 2013, birds were monitored at 20 or 30 of these point locations via time-distance point counts (breeding) or area searches (winter). To ensure data from all 40 random locations were included in analyses, monitoring data from two consecutive years were combined. As a result, some points were monitored twice during the period of analysis. Even so, I have treated each survey as an independent monitoring event, thereby assuming each visit to be equally representative of the bird community for the entirety of San Antonio Missions National Historical Park. When translating avian densities to park-wide populations, I used an area of 334 ha to represent San Antonio Missions National Historical Park including the Rancho de las Cabras unit.
