A study published recently in the journal Science reveals that since 1970, bird populations in the United States and Canada have declined by 29 percent, or almost 3 billion birds. The results show tremendous losses across diverse groups of birds and habitats – from iconic songbirds such as meadowlarks to long-distance migrants such as swallows, as well as backyard birds including sparrows. In fact, three out of every four Meadowlarks have vanished.
Within these results, certain groups of birds were particularly hard hit. Grassland birds saw a 53-percent reduction in population – more than 720 million birds – since 1970. Shorebirds, most of which frequent sensitive coastal habitats, were already at dangerously low numbers and have lost more than one-third of their population. Furthermore, the volume of spring migrations, measured by radar in the night skies, has dropped by 14 percent in just the past decade.
With these facts in mind, we should all plan to feed our birds this winter while their food source is scant, avoid pesticides in our gardens, and thoughtfully consider our actions which adversely affect the environment. A world without birds is unimaginable.
