Default Northern Cardinal Occurance Patterns

Cornell Lab of Ornithology

Northern Cardinal is a widespread and familiar bird, occurring throughout most of the East and even in the desert as far west as Arizona. It is easily identified, often comes to feeders, and is essentially nonmigratory. Nonetheless, there are seasonal patterns in the observations of Northern Cardinal submitted to eBird. Here we introduce a new visualization of eBird data that clearly shows these patterns in bird occurrence, and provide some interpretation of the variations seen in a “resident” species.

When we see land as a community to which we belong, we may begin to use it with love and respect."

Cardinals are common by me. Funny thing is I don't think I've ever seen a cardinal nest before. You'd think I would have seen one by now.
