The oldest recorded Northern Cardinal was a female, and was 15 years, 9 months old when she was found in Pennsylvania.The best example of an umbrella species in Rhode Island is the Cerulean. The umbrella species concept has nothing to do with similar foods, similar nesting locations, or similar habits. A perennial favorite among people, the Northern Cardinal is the state bird of seven states. The Northern cardinal, meanwhile, had the least overlap in living quarters, preferring scrubby, shrubby habitats most of the time.When a male sees its reflection in glass surfaces, it frequently will spend hours fighting the imaginary intruder. The male cardinal fiercely defends its breeding territory from other males.A few weeks later, as levels of aggressive hormones subside, these attacks should end (though one female kept up this behavior every day or so for six months without stopping). Birds may spend hours fighting these intruders without giving up. This long breeding season allows for multiple broods each year and ensures the survival of at least a few offspring. For their first nests in early spring, cardinals often choose the protection of evergreens. In their nests, these birds produce and raise one or two broods of young each year, with each of these clutches including between two and five eggs. Many popular backyard birds build the classic cup-shaped nest, including robins, cardinals, and hummingbirds. The nesting habits of wild birds, however, vary greatly. A completed cardinal nest measures about 3 inches in height and 4 inches in diameter. When most people think of a bird’s nest, the same image likely comes to mind of a round nest made of twigs and other debris. The female cardinal is the nest builder, and she will choose a position in dense vegetation. Cardinals generally stay in the same area, which helps get a jump-start on nesting, with some laying eggs by February. Nest materials include twigs, stems, leaves, grasses, grapevine, pine needles and even small pieces of trash. Both males and females do this, and most often in spring and early summer when they are obsessed with defending their territory against any intruders. They tend to stay in one area over winter. Many people are perplexed each spring by the sight of a cardinal attacking its reflection in a window, car mirror, or shiny bumper. The cardinal bird call for males is aggressive singing to protect their breeding and nesting, whereas females will sing more elaborate songs.A mated pair shares song phrases, but the female may sing a longer and slightly more complex song than the male. This may give the male information about when to bring food to the nest. Only a few female North American songbirds sing, but the female Northern Cardinal does, and often while sitting on the nest.
