To the Editor: I read the recent article on the declining bird population by Bea Lewis with much interest. Just last year we resumed bird feeding in our backyard and were quite pleased with the results. I put up our feeders the first day of October and have had to add seed several times. We have much activity daily.

I was disappointed when I heard a one-liner on local radio during their news referring to your article, stating that the bird population is down billions due to “climate change.” If you read the article , Bea cites several items as serious causes of bird-population reduction. Pesticides, loss of habitat (to farmland and housing developments), and human activity (cats, window and building strikes, power lines and wind turbines) are cited as the most common. Climate change, and gradual higher temperatures was mentioned but not as the major issue.

There was a report cited from the National Audubon Society that warned “if” the earth warms by 5.4 degrees by year 2100 it could cause issues for many birds. Not a scientific study, but I personally looked up the average temperature for the month of July in Manchester from 1945 to 2018. The trend line calculated in less than .5 degrees average temperature increase over the 74 years. That rate will have to increase 10 times over to reach 5.4 degrees by 2100.

Unfortunately, climate change is a convenient and popular cause cited for many issues . . . regardless of the accuracy of such claims.
