Explanation of Trend Tables
The 186 bird species that breed regularly in New Hampshire are included in three tables above, corresponding to 1) decreasing species, 2) stable or increasing species, and 3) species for which there are insufficient or uncertain data.

In most cases, the data used in this categorization were derived from the Breeding Bird Survey (www.pwrc.usgs.gov/BBS), an international bird monitoring program coordinated by the U.S. Geological Survey. Species were placed into one of these three categories by comparing trends at the state and regional levels. When an actual New Hampshire trend is available, it is included in the tables (e.g., +1.3). These trend values represent the average annual rate of change since 1966. If data - including from other sources - indicate a consistent, but not significant, increase or decrease in population, this in indicated in the table without a numeric value. Note that because regional trends were also considered when assigning a species to one of the three categories, there are occasional cases where the New Hampshire trend does not correspond to the broad trend category for the table (e.g., "decreasing" species in the "uncertain" table, etc. ). These are generally cases where the broader regional trends were weighted more heavily than the state trend, often because there are limited or otherwise insufficient data to accurately evaluate the species' populations in New Hampshire.

Each table also lists the major habitats in which each species is found during the breeding season. See the full "State of the Birds" report for more detail on trends and habitat relationships.
