Franklin Mountain Hawkwatch 30 Year Report

CLICK HERE to view the full report which includes species specific data.

To read the table at the top portion of the page, a green to red gradient allows for a quick view of the highest count year (dark green) to the lowest (dark red).

At the bottom of the table, there are summary statistics that show the average values for each species over the years. This is followed by how this year compares to an average year.

The pie charts located below the table shows the composition of the most common hawks for both the Fall of 2019 and then for the twenty-year average.

All of the scatter plots following the pie charts have five fine dashed lines:

  • The middle-dashed line shows the mean or average value.
  • The dashed line above and below the mean line represents one standard deviation, while the outside dashed lines represent an additional standard deviation. One standard deviation represents 68% of the data in a normally distributed system, while two standard deviations represents 95%.
  • The R2 value is the correlation coefficient and marks the goodness of fit for a linear function. An R2 value of 1.0000 indicates a perfect fit of your data to a line, whereas an R2 value of 0.0000 shows that the data points are seemingly random and have no linear fit.

Why Birds Matter...

Birds are important because of the role they play in the natural world as pollinators and seed disbursers, assisting with the balance of nature by eating insects. They also clean up things that would go unattended otherwise. Birds are important TO ME because of the kinship that I feel with another living species, and the joy that they bring to me year around. Encountering spring migrants feels brand new every time! I feel responsibility for their well-being and take care not to disturb their nesting with unnecessary sounds, disturbance or habitat destruction. I respect the incredible work they do to bring about future generations.

Birds have always been an early warning system for our environment–the “canary in the coal mine.” It was the decline in bird species high on the food chain that tipped us off to the dangers of DDT and other chemicals. More recently, high altitude and high latitude birds are demonstrating the first definitive effects of global change. If science had been more advanced in the 1800s, the extinction of the Passenger Pigeon could have served as a warning about habitat destruction. This not just about protecting the birds–although that is a worthy goal–but all of these threats will ultimately reach the human race.

In addition to being indicators for environmental health, birds matter because they allow people all over the world to enjoy and appreciate nature. Caring about birds often leads to caring about their habitats and creates a stewardship ethic to protect our natural resources. Birds connect communities.
