Appendix B: Population Trends for New Mexico
(Data from North American Breeding Bird Survey, 1966-1994)

Terms for Trends

Declining: Population declines are statistically significant
Negative: Population appear to be decreasing, but we don't know for sure
Stable: Populations apparently not changing much
Positive: Populations appear to be increasing, but we don't know for sure
Increasing: Population increases are statistically significant
?: We do not know if it is increasing, decreasing, or stable (sample size too small to tell)
