The Song of the Northern Cardinal is dimorphic.  The songs between male and female Northern Cardinals within the amplitude of the harmonics.  There is a minimum amplitude of -33 dB to the peak.

Learning

The Male bird is the one who does most of the parental care and  during 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  to  gain their initial territory.Then  as time goes on the males will  put  less 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  hypothesis which shows cardinals learning degraded versions of neighbor songs in order to differentiate territories.

Female Song:

The Female Song trait for the Northern Cardinal is highly unusual for songbirds.  Even though Females sing and their songs are generally longer and more complicated Females sing way less then their male counterparts. In one  study 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.

Future Work

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  the Females role in the courtship process is. Future work with the Northern Cardinal will most likely reside in their ability to sing and  work will be done to attempt the full documentation of this process.
