Here’s a riddle for you. What \month has an invisible baby bird species? Answer: the month when we see cardinals at feeders for the first time each winter. It seems that, in winter, baby cardinals do not exist. However, what happens to the babies in the summer? Why are they not seen at the feeders? Each winter, young cardinals stay hidden in brush. They are not seen by humans as they are busy noggling mothers. Each summer, the young birds rely on the availability of food provided by their parent birds, living in their parents' territory. When the parents leave, the juvenile birds are free to explore the outside world. Migrating birds do not want to leave their food source. Parents force them to remain in their own food source throughout the migration. Each winter, as the temperature drops and food availability decreases, the adult birds migrate to their feed.

Why don’t you see baby cardinals in the winter? Because no baby cardinals are being born in winter! Like all North American songbirds, cardinals are seasonal breeders. They raise their young during the time of year that food is plentiful. During breeding season, insects, and other protein-rich food sources are available and easy to gather. The breeding season starts in late winter and continues through to summer. For most regions, that timeframe is March through August. This is dependent on local climate conditions.
Winter is all about survival for cardinals. Temperatures drop, food becomes scarce, and the energy needed to find enough food for warmth is immense. The energy and resources needed to raise chicks is massive. Parent cardinals have to find food to feed their growing babies, but soft-bodied insects and caterpillars are nowhere to be found in winter.
As opposed to nesting, cardinals spend the colder months conserving their energy, foraging for seeds and berries, and braving the harsh conditions. This is why all of the cardinals you see at your feeder in December and January are fully grown birds. There are no eggs being laid, no nests being built, and no chicks are hatching. The entire breeding cycle halts until conditions become more suitable in the spring.
The Timeline of Cardinal Nesting Keeps Offspring Out of Winter
Understanding the life cycle of cardinals can help explain their absence during the winter months. Breeding cardinals in the spring and summer months undergo a rapid process. After a male and female cardinals construct a nest in a dense shrub or low nestled tree branch, the female will lay 3 to 4 eggs. The female will incubate the eggs for 11 to 13 days before they hatch.
When baby cardinals leave the nest, they are ready to go after only 9 to 13 days. Both parents continue to work hard after the chicks emerge to feed the growing baby cardinals. After the young birds then learn to forage and develop their flight skills, they are not fully independent even after fledging. Parents continue to feed them for another three to four weeks.
Baby cardinals will be fully grown by the end of summer or early fall. Young male cardinals will begin to grow their signature red feathers; however, it may take a few molting cycles before they are all fully developed. Young female cardinals will get the beautiful warm tan and slight reddish feathers. By the time winter arrives, young cardinals will be all grown up and will be harder to tell apart from the adult cardinals at your bird feeder.
Cardinals sometimes have multiple broods in a single season—often two or three. This means that breeding activity occurs well into summer. However, even the latest broods are fully grown and self-sufficient by the time the frost comes. This protects them from having vulnerable juveniles face the challenges of winter.

Where Adult Cardinals Go to Stay Safe in Winter
Cardinals are not migratory birds. Hence, they are mostly considered permanent residents and stay within their range, which covers Eastern United States, portions of the Southwest, and parts of Mexico. Wintering further south is not something they do, meaning they must find some adequate safe shelter nearby. During winter's coldest months, cardinals use dense covers to help them withstand freezing temperatures and weather extremes.
The branches and leaves of evergreen trees and bushes become shelter for many animals during the winter. They help keep out the wind and keep in the warmth. The hollies, spruces, cedars, and pines are places where cardinals cozy up in. They keep out the cold by fluffing their feathers and letting warm air collect against their bodies. During really cold nights, it’s common to see cardinals snuggling in the same tree to conserve body heat.
Thick branched or dead-leaf persistent varieties of winter hardy deciduous shrubs provide excellent winter protection. Bramble, dogwood and viburnum sheltering pockets protect cardinals from predators and the elements. These pockets provide the primary refuge for cardinals outside of active feeding.
Social behaviors of cardinals change in winter. Although cardinals are usually protective of their nests during breeding season, they are known to create loose flocks during winter months. Compared to chickadees and goldfinches, who make tighter flocks, cardinals winter groups are more closely foraging and roosting together. The more birds present means more eyes on the lookout for predators.
5 Ways to Attract Cardinals to Your Backyard All Year Round
Cardinals can be supported in all seasons, even when baby cardinals aren’t around, as long as you make a few modifications to your habitat to enjoy their company year round. Here is the best method:
Cardinals will eat cracked corn, safflower seeds, and sunflower seeds. To keep the food available all winter, when types of food available in nature decrease, keep your feeders filled. As cardinals will forage on the ground as well as at upper tiers, use platform or hopper feeders at different heights.
Add protective and dense shrub species. Choose native evergreens such as holly and juniper as they provide shelter all year. Use winterberry or serviceberry as they provide food sources. Dense plantings create habitats cardinals require for nesting and for winter roosting.
Cardinals need water to drink and bathe even in freezing temperatures. A heated birdbath is a great addition to your winter bird habitat. Even when everything is frozen solid, clean water attracts cardinals.
Designate areas for winter shelter. Wind block and concealment areas can be created by leaving brush piles in a yard corner and allowing ornamental grasses to be uncut through the winter. If you have evergreens, avoid heavy pruning that removes the interior roosting branches where birds perch.
Avoid using pesticides and chemicals in your yard. In breeding season, cardinals rely on insects, and they also need healthy habitats to thrive. When you keep your yard free of chemicals, you support the entire ecosystem that cardinals rely on from caterpillars in the spring, to seeds and berries in the fall.
You’ll enjoy cardinals all year long with the right food, shelter, and water. While no babies will be present during winter, the bright red males and warm-colored females will bring bright colors and life even in the coldest gray days. When the spring comes again, you may see a pair starting to build a nest in the shrubs you planted.
Happy birding!
