The very small W chromosome is what remains of the original Z chromosome that has degenerated over the course of time, similarly to what happens with the human Y chromosome.Īccording to experts if you were to take a sample of the chromosomes present in cells from the mid-line where there is the split in a gynandromorph, you would find a combination of female and male chromosomes.īefore you start thinking that in the current climate it might be a good idea to refer to gynandromorphs as intersex, it’s probably best to avoid it as it is not possible to compare the kind of cell mutations that occur inside birds with anything that occurs inside humans. Female cells have a W and Z chromosome, while male birds have 2 gene-rich and very large Z chromosomes.

However, they act in the exact opposite way as they do in humans. With birds it is similar, they have sex chromosomes. In human beings like you and me, male cells have one small Y chromosome and an X chromosome, while female cells have 2 copies of the gene-rich and very large X chromosomes. So, we now know what they are, how do they become what they are? Understanding the Biology Given the aesthetic differences there are between the male cardinals and female cardinals, gynandromorphs are much easier to pick out among cardinals. The interesting thing is there are a number of different animals and birds, including chickens and some insects that are gynandromorphs, but they are not always easy to spot. Sound impossible? There is a scientific name for it.īasically, a creature that is half female and half male is referred to by scientists as being a gynandromorph. It looked like two birds had been sewn together. Not only that, but the colors were split down the middle. What was so strange about this cardinal? Half of its body was red, while the other was tan. According to NBC News early 2018, a couple, Shirley and Jeffrey Caldwell, they spotted and snapped the strangest cardinal they had ever seen. The short answer to this is that yes, birds on some occasions can be both male and female. Males fend off any rivals by singing, and taking defensive action, as noted aboveĪs a final note, after looking at the major differences between male cardinals and female cardinals, there’s one exception we need to discuss.Females incubate their eggs, while the males bring food to them.Female cardinals do much of the nest building, while male cardinals help supply some of the materials for it.Within their relationship, both partners have specific roles and duties. When a male and female cardinal become a breeding pair, they mate for life. It is thought that a single cardinal could have over 24 different song variations and there are often different songs sung by cardinals from different geographical populations.

Female cardinals also have more elaborate songs than males.It is thought that females sing and tell males they need more food.While male cardinals generally sing in an aggressive fashion to protect their breeding and nesting territory and will attack any intruders with a lot of fury and anger, female cardinals are more tactical with their singing.Despite this shared talent, they have different levels of ability and skill when it comes to singing. It makes sense that as cardinals are songbirds, at least one half of the gender divide would be adept at holding a tune.Ĭardinals are different many other types of songbirds, as both male and female birds can sing. While appearance is the most obvious way to tell the difference between male and female cardinals.They have the same color of bill and the same black face mask. Female cardinals, on the other hand are known for their subtler, some would say duller, pale brown coloring with just gentle reddish tips on the crest, tail and their wings.They also have a reddish bill and a black mask covering their face.As cardinals are principally red and they take their name from Roman Catholic cardinals who wore red robes, if you are looking at a bright red, almost outrageously so, you are looking at a male cardinal.So, How Do You Tell A Male Cardinal From a Female Cardinal?Ĭompared to other species where it is sometimes very difficult to figure out the gender, Cardinals are incredibly easy to pick out the males from the females. 1 So, How Do You Tell A Male Cardinal From a Female Cardinal?.
