Starting today, you will find that posts in the Bird Focus category are now tagged with the birds’ North American population trend status over the past 30 years: Increasing, Stable, and/or Decreasing. Those posts featuring more than one bird with differing population trends will be tagged for each trend, and the first mention of each bird in the post will carry its population trend in parentheses. This additional tagging will enable you to select posts on the basis of population trends.
Note that all categories and tags, along with any related articles, appear at the bottom of each post. By clicking on any one you will be able to select that group of posts.
