Thousands of birds migrate through The Woodlands every fall. The reason – food. As days grow shorter, birds begin to head south in search of abundant food and warmer temperatures. Lucky for us, The Woodlands happens to lie right along the path that many species take on their journey south. Our warm climate and dense vegetation provides an ideal rest stop for swifts, swallows, hummingbirds, hawks, flycatchers, warblers and more. Our parks, yards and preserves are heavy with greenery, berries and flowers throughout the fall, but are they providing the food these migrating birds need?
The Early Bird Catches the Worm
…and the berries, insects, seeds and nuts. The most sought after avian delicacies varies with the season. Research shows that all birds, migrating and resident species, require different nutrition in winter than in warmer months. Summer is breeding season for most species and protein to produce healthy eggs and chicks is in high demand. Protein means insects and lots of them. Consider that a single pair of chickadees must find 6,000-9,000 caterpillars to raise their young!
As breeding season ends, birds shift their diet from protein to fat to help them survive cold nighttime temperatures. Fat intake is extra critical for migrators in preparation for the grueling flight ahead. Produce from Woodlands natives such as American beautyberry, wax myrtle, coral honeysuckle, native dogwoods and viburnums, and yaupon holly are prized. Right now, most of these species are in the early stages of their fall and winter fruit and nut production.
Our native plants (and insects) have co-evolved with birds over the centuries, meaning birds depend on the specific nutrition these species provide. So, not just any seed, nut or berry will do. Consider the popular non-native plant, nandina (heavenly bamboo). It produces a bevy of bright red berries – quite attractive to our eye as well as the bird’s. Unfortunately, nandina berries, like most non-native berries, are sorely lacking in fat and other nutrients. Much like feeding french fries to a marathoner, these imitation foods leave birds depleted, unable to complete their migration route or make it through a cold night.
Just like you and me, birds need the right food. Here’s how to help.
Fall in Love with Natives
Migrating birds face several threats to their continued survival: the greatest being loss of habitat. We often think of habitat loss as a paved over forest. Yet, despite the green appearance, our lawns and landscapes have the same impact if they’re devoid of native plants. Much like a parking lot, they become a food desert for birds and other wildlife.
The simplest yet most impactful action you can take to support our migrating birds this fall is to add native plants to your landscape. Remove non-native or invasive plants to ensure you’re providing only nutrient rich food, not french fries.

For those who go one step further in helping our feathered friends with backyard feeders, consider that not all seed mixes are the same. Cheap mixes are full of milo, wheat, red millet, and various grains that birds can’t make use of. Most all of these “low cost” seed mixes contain little protein and almost no fat. The same holds for black oil sunflower seed. Cheaper seeds are often those which didn’t fully mature and lack protein and fat. Spend a little more on a quality seed and you’ll be rewarded with more frequent and healthier visitors.
