RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct Mexican Breeding Bird Survey (BBS) (PIF
Monitoring Needs doc)
- Second
priority monitoring action – Conduct border (U.S.-Mexico) bird
surveys (PIF Monitoring Needs doc)
- High

connectivity of Mexican and
U.S.
source populations of select species (including AUOR) in Falcon
riparian/thorn forests (South Texas Brushlands)
