The Northern cardinal builds it nest on dense shrubbery and small trees. The nests are usually placed 1 to 15 feet above ground and are made of twigs, bark strips, leaves, roots, and paper. The nests are lined with vines, grass, and hair. Only the female northern cardinal builds the nest while the male cardinal sticks close by to protect their territory. The female cardinal lays 2 to 5 eggs that are white in color but heavily speckled with light brown to dark brown marks. The female cardinal also incubates the eggs alone while the male cardinal continues to guard the territory and find food feeding himself and the female bird as well.
The cardinal’s diet consists mostly of seeds, fruit, insects, and small animals like worms and lizards. Due to their beautiful plumage cardinals are among the most popular birds to feed and attract. Since they are non-migratory, cardinals will stay in the same area year round as long as there is adequate shelter and food.
For this reason, plenty of people set up birdhouses and feeders for them. You can do a few things to make safer area, ensuring many return visits by your cardinal friends.
- Reflective surfaces. Cardinals are known to attack their reflections as a territory-protecting measure. Though this behavior isn’t generally fatal, it may cause beak damage as well as unnecessary stress. You can prevent this by eliminating the reflection of windows or mirrors near nesting and feeding areas. For windows, try using screens or bird netting to deter them. Cover car mirrors, when not in use, with opaque items such as plastic bags.
- Harmful chemicals. Avoid using chemicals and poisons in the vicinity of your bird feeders and birdbaths. Insecticides, herbicides, and many fertilizers can contaminate your food and water sources. This can often be lethal to your Cardinals.
- Predator-accessible feeding areas. First, if you have pets that go outdoors, you should do your best to keep them away from Cardinal feeding areas. In addition, you should avoid placing feeders or scattering seed near low shrubs and bushes, and anywhere else that predators may hide and easily attack them.
If you have no conditions to attract birds, buy a cardinal bird popup card to setup in your house.
