Color of Cardinal Eggs is a Unique and Breathtaking Phenomenon
The vibrant colors of birds' eggs are a fascinating topic, especially when it comes to cardinals. Known for their stunning plumage, these birds often lay eggs with captivating hues. The color of cardinal eggs is no exception, boasting a shade that is as unique as it is breathtaking. This article will delve into the ins and outs of cardinal eggs' colors, highlighting the science behind them and some interesting facts you might not know.
What Do Cardinal Eggs Look Like?
When you hear about cardinal eggs, you might picture a bright red or pink shade. And while it's true that some cardinals lay eggs with pink or reddish undertones, it's not the only color they can produce. In reality, the color of cardinal eggs can range from pale blue to pale brown, with speckles of lavender or red. A person familiar with these eggs would recognize them by their light blue or blue-green ground color with a very red-brown to pale red blotched background. The speckles, too, can range from dark specks or diminutive elliptical splotches. However, most of the time, cardinal eggs will have some delicate looking speckling of red-brown to reddish spots. Understand that these markings often appear in a wobbly pattern and are not completely consistent.
Cardinals are known for their complexity, and it's natural that their eggs follow the same pattern. These marks act as more than mere aesthetic additions; their color plays a crucial part in the process of natural incubation and embryo development. However, more about this later.
Why Do Cardinals Lay Eggs of Different Colors?
Several factors contribute to the stunning colors of cardinal eggs. In addition to genetics, a bird's diet can affect the biochemistry of the eggshell. Some experiments have demonstrated that an egg's pale color may be related to the amount of calcium and certain minerals that the mother ingests, especially when those birds are primarily vegetarian. Here's a table showing a rough breakdown of these inorganic variable substances in eggshell distribution for cardinals and some other national resident species.
