Winter Trend: Increasing

Wild Turkey Winter Trend 1987–2025

Wild Turkeys, 1987–2025. The dark purple line shows the trend overtime predicted by our statistical model, while the shaded purple area shows where we are 95% confident the true trend lies. Gray points are the number of turkeys actually observed in participants’ backyards, averaged per observer.

What’s the Story?

Wild Turkeys might not be the first species that comes to mind when you think of backyard birds, yet many participants report them in their backyards! Today, they can be found in every part of New Hampshire, which makes it hard to believe that they were once hunted to local extinction.

After an unsuccessful reintroduction attempt in 1969 (cut short by a harsh winter), New Hampshire Fish and Game successfully reintroduced Wild Turkeys to the Connecticut River Valley in 1975. From there the population has steadily spread and grown.

Our statistical analysis shows the success of the reintroduction: a negative binomial regression shows a significant upward trend (β = 0.112 ± 0.008 SE, z = 14.88, p < 0.001).

This translates to reports of Wild Turkeys increasing by about 12% per year, even when accounting for changes in the number of Backyard Winter Bird Survey participants over time.

As you can see from the graph, there is year to year variation in Wild Turkey numbers. For example, in 2024 relatively few turkeys were reported. This was likely due to a cold, wet spring that reduced recruitment when many young birds did not survive.

Turkeys are highly adaptable birds. While harsh winter conditions (especially in northern New Hampshire) can limit their range, farms and other landscapes with abundant food have helped them thrive. They also forage for acorns and beech nuts, often leaving telltale scrapes in the snow where they’ve been searching for food.

Feeding Tips

  • You’ll often see Wild Turkeys feeding below bird feeders.
  • While Wild Turkeys enjoy cracked corn, we don’t recommend feeding them directly. Instead, consider your landscape and how you might provide natural food sources, such as oaks and beeches that produce hard mast.

In Your Backyard

  • Watch for Wild Turkeys traveling in flocks, especially during fair weather. Their large tracks are also easy (and fun) to follow in fresh snow.
  • Dense conifer stands provide excellent winter roosting sites. These trees not only insulate turkeys from the cold but also keep patches of ground beneath them snow-free, making foraging easier.

Understanding the Graph and Statistics

Observed Data (gray points):

The average number of birds counted per participant each year.

Model-Predicted Trend (dark purple line):

A line from a statistical model that estimates the overall trend in bird numbers over time, smoothing out year-to-year fluctuations.

95% Confidence Interval (shaded purple area):

The range around the predicted trend where we are 95% confident the true trend lies. Gray points inside this band indicate observations that are consistent with the predicted trend.

Other Stats You Might See in the Story:

  • β (slope) and SE (standard error): These numbers tell us how strongly and precisely the bird counts are changing each year.
  • p-value and z-value: These tell us whether the observed trend is statistically significant (i.e., very unlikely to be due to random chance). For example, a p-value less than 0.05 usually means a statistically significant trend in either direction.

The Takeaway: These graphs show how bird populations are changing over time. The model helps us see the overall trend and the confidence interval shows how certain we are about that trend.
