The Northern Cardinal, a frequent visitor to bird feeders, is one of the most admired backyard bird species.
Every greeting card company in North America must use this birds picture against a backdrop of snow during the Christmas season.
And why not, he's one of those birds that once you've seen him you'll have to admit he is a looker.
Read on to learn where and when Cardinals nest.
The male is a bright red bird with a pointed crest on the top of his head.
The female is mostly buff brown in color with some red on her head, wings, and tail.
Both have small black masks on their faces that surround the bill and eyes with the males more pronounced. They measure 8 1/2 inches long.
Northern Cardinals have been steadily expanding their range north while also inching their way westward.
This northward range expansion offers more bird watchers a chance to see and observe this bird.
One of the explanations for the Cardinals move northward is the proliferation of food available from people feeding birds.
These birds are permanent residents throughout their range.
While a somewhat secretive bird while nesting, you may still be able to watch from a distance.
Getting too close to the nest site while the female is in the building stage will cause her to abandon the site. Always watch from a distance.
At your bird feeder, one of the mating habits you may see is referred to as "mate feeding".
What you'll see is the male pick up a seed, hop over to the female, and the two momentarily touch beaks as she takes the food.
Mate-feeding continues through the egg-laying and incubation phases of breeding. This behavior is actually common to many of our backyard birds.
The video above shows an example of a male Cardinal offering food to the female while she is incubating the eggs in the nest.
Mate feeding is thought to be part of the pair bonding process.
That is, it gives the female an idea of how well the male will provide food to their eventual young.
Typically, pairs remain together the whole year. In winter the bond may be relaxed.
Pairs often stay mated until one dies at which time the surviving mate will look for another partner. Mating for life is often used in field guides to describe this behavior.
So when do cardinals begin nesting? The breeding season can run from March to as late as September. The female will lay 2-5 eggs that are buff-white with dark marks.
The female builds the nest while the male keeps a close eye on her and the surrounding territory for predators and other males.
The nest is made up of twigs, bark strips, vine leaves, rootlets, paper, and lined with vines, grass and hair.
Favorite nesting locations are in dense shrubbery or among branches of small trees. Nest are built 1-15 feet above ground.
They do not use bird houses but have been seen on abandoned feeders and other ledges that provide some cover. Here is some video of a nest in a cedar tree we cammed live on the internet one season.
The female is the only one to incubate the eggs. Egg laying may begin 1 to 8 days after nest completion. Incubation begins after the last egg is laid.
The female may sit for short periods before the last egg is laid but come and go more frequently.
The males duty during this time is to feed her on the nest and protect their territory from intruders.
Watching and listening closely, You'll hear the male call and the female will leave the nest to be fed by the male. This can be a dangerous time since the eggs or young are left alone.
The female will incubate the eggs for 12- 13 days.
When the eggs hatch, both male and female will feed the young.
The baby Cardinals wild leave the nest in 9-11 days after hatching. Often the young are unable to fly much the first day or two after fledging.
Each season the pair will attempt to raise two broods. A new nest will be constructed for second broods by the female and old nest are not reused.
The male continues to feed the first set of young for up to two weeks after leaving the nest. During this time the female will be incubating her second clutch.
This will keep the male busy by continuing to feed the female, the first brood, and still protecting their territory.
Any males born this season will initially look like the female but by winter they will have the more pronounced black mask, crest, and red feathers of adult males.
While they won't reuse a nest, studies show that having more nest may reduce predation. These birds often nest near previous nest so leaving nest might offer some help with regards to predation.

These birds are often parasitized by the Brown-headed Cowbird. The female Cowbird watches these birds as they build their nest and lay their eggs.
While the female Cardinal is away, the Cowbird will visit the nest, remove an egg, and then lay one of her own eggs.
Cardinals and Cowbird young are roughly the same size and grow at pretty much the same rate.
What this means is, baby Cardinals have a better chance at survival with Cowbirds in the nest than other smaller species.
Never remove a Cowbird egg because the female often returns to check on her egg. If her egg is gone she may cause more problems such as destroying more eggs.
Sometimes Cowbirds may remove an egg, lay one of their own eggs, and then pierce remaining eggs.
Cardinals are unable to distinquish a Cowbird egg or hatchling from their own. This results in the Cardinals raising the Cowbird all the way to self reliance.
Cardinals may protect a territory size of 1/2 to 6 acres during breeding season. With the average +/- 3 acres. Males will chase other males and females will chase other females from the pairs territories.
Cardinals birds often fight with their reflection in house windows and car mirrors. To see what you can do about this behavior check this page for solutions.
In the wild, the adults food consist of insects, spiders, wild fruits, berries, and weed seeds.
In winter the Cardinals diet is more plant based which includes seeds and berries in the wild. Some insects under leaves may be found to supplement their diet.
Preferring to perch while eating at bird feeders, the ideal bird feeder for them is a the tray feeder style.

You're likely to notice that these are often the first birds to arrive at the feeders in the morning and the last birds to eat in the evening.
Around my home they make their last feeder visit at dusk.
Cardinal birds tend to be very territorial in their feeding habits during the breeding season.
If you want to see them at your bird feeders during Spring and Summer, try placing a couple of feeders out of sight from each other. This will allow pairs to feed at the same time without all the chasing that happens.
One in your front yard and one in the back works well. In winter they are less territorial around bird feeders.
Northern Cardinals are permanent residents throughout their range and do not migrate south. Their range has been expanding further North.
A Heated Birdbath can help provide the drinking and bathing water they need all year.
At some time or another you may see a male that has no crest or head feathers at all, the bird looks bald.
This is not unusual and happens to many types of birds. The reason isn't known for sure.
Theories include parasite or dietary problems. The good news is, the condition isn't permanent and the bird will grow new feathers.
House Wrens have pierced eggs in nest.
