Learning<\/h1>\n
The Male bird is the one who does most of the parental care and \u00a0during that time period teaches the young numerous Songs. Both Male and Female Northern Cardinals learn song. Both sexes learn song during the breeding season. To the human ear the song of the male and the female Northern Cardinal sound similar, but as stated above are slightly dimorphic. Young male Cardinals will learn more complex songs \u00a0to \u00a0gain their initial territory.Then \u00a0as time goes on the males will \u00a0put \u00a0less time into their songs and they will become shorter and the male Northern Cardinal will put more time in effort into care and defense for their young. There is also the ranging \u00a0hypothesis which shows cardinals learning degraded versions of neighbor songs in order to differentiate territories.<\/p>\n
Female Song:<\/h1>\n
The Female Song trait for the Northern Cardinal is highly unusual for songbirds. \u00a0Even though Females sing and their songs are generally longer and more complicated Females sing way less then their male counterparts. In one \u00a0study the females sang an observed amount of 0.5% of time, this was out of 45,000 minutes. Females sing over a much shorter time period then males do. Females rarely sing alone as they are generally accompanied by their male partners.<\/p>\n

Future Work<\/h1>\n
Female Cardinals and their involvement with courtship is a very unknown phenomena. There have been only two populations where female song-dance courtship have been observed. Through multiple samples of Northern Cardinal populations we can determine if this is more common, and what exactly \u00a0the Females role in the courtship process is. Future work with the Northern Cardinal will most likely reside in their ability to sing and \u00a0work will be done to attempt the full documentation of this process.<\/p>\n
