Recent research has underscored the significance of consistent singing practices in songbirds, emphasizing the rapid decline in their vocal muscle strength in the absence of regular singing. Female songbirds show a preference for the songs of males who engage in consistent vocal exercises, underscoring the importance of such activities.
Studies on songbirds underline the essential role of daily singing in maintaining vocal muscle robustness and allure, offering insights applicable to human vocal training and speech therapy.
During the Christmas season each year, the exceptional singing talents of individuals like Mariah Carey and George Michael are particularly noticeable, often evoking profound emotions.
Singing is arguably one of the most intricate activities, involving numerous, largely unseen, muscular movements. Mastery in singing requires acute coordination of countless muscles, necessitating significant talent and practice.
Vocal Cord Training: A Neglected Field
While athletes routinely focus on training their limbs and body muscles, the question arises: what about the muscles in the vocal cords?
“We have limited understanding about the impact of exercise on these muscles and their responsiveness to training in humans,” remarks Professor Coen Elemans from the University of Southern Denmark, a sound production specialist, “Access to a singer’s vocal cords for study is typically off-limits.”
Findings indicate that male songbirds require daily singing exercises for maintaining vocal muscle health and enhancing song quality, crucial for attracting mates and sustaining social interactions.
Discoveries from Songbirds
A new study, published today (December 12) in the prestigious journal Nature Communications, reveals that male songbirds must sing daily to exercise their vocal muscles and produce appealing songs, a fact not unnoticed by the females.
“Singing plays a pivotal role for songbirds, used in attracting mates, defending territories, and fostering social connections,” states Dr. Iris Adam, the study’s primary researcher.
The study demonstrates the necessity of training for maintaining peak vocal muscle performance in songbirds, with singing exercises being particularly vital.
This research was carried out by a global team of scientists from the University of Southern Denmark, Leiden University, University of Umea, and the University of Vermont, under the guidance of Assistant Professor Iris Adam and Professor Coen Elemans from the Department of Biology at the University of Southern Denmark.
Vocal Muscles Require Regular Exercise
“While it’s widely acknowledged that songbirds’ singing is governed by rapid vocal muscles, our understanding of how these muscles respond to exercise was limited,” explains Dr. Adam.
The study reveals that without regular use, songbirds’ vocal muscles rapidly weaken, showing a 50% reduction in strength after just a week of not singing.
“This was an unexpected finding,” comments Dr. Adam, “both the marked reaction of these muscles and the swift decline in their performance. It truly is a case of use it or lose it!”

Partners Detect the Variance
The research team observed noticeable differences in the songs pre and post-exercise.
“Though these differences might be indiscernible to us, our song analyses clearly showed the effects,” notes Dr. Adam.
To determine the significance of this difference to the birds, the team played songs to female zebra finches, assessing their preference for pre or post-exercise songs.
“75 percent of the female zebra finches in our study showed a preference for songs from males who had undergone vocal exercises,” shares Katharina Riebel, a co-author and animal behavior specialist.
The Daily Dawn Chorus: A Fresh Interpretation
“These findings suggest an alternate reason for the extensive and daily singing of birds,” proposes Elemans.
The purpose of the widespread morning singing ritual of birds in spring and summer remains a mystery to scientists.
“Much of this singing seems superfluous. They sing when there’s no apparent need,” observes Adam.
“Our findings suggest that daily exercise is crucial to prevent a decline in muscle performance,” adds Elemans, “Moreover, the absence of exercise is perceptible in their song, with females showing a preference for songs from exercised males.”
Hence, songbirds may need to invest considerable time and energy in daily singing to remain attractive.
This might apply to all animals.
Distinct Traits of Vocal Muscles
Studying the zebra finch’s vocal muscles led to another significant discovery.
“When humans exercise leg and arm muscles, they typically become slower,” states Per Stål, a co-author and human muscle exercise physiology expert.
Contrarily, songbirds’ vocal muscles don’t become stronger and slower with exercise like limb muscles, but instead, they get weaker and faster. This contrasts with normal limb and body muscles.
“This unique response of vocal muscles might be applicable to all vertebrates, including humans, given their developmental similarities,” suggests Dr. Adam.
“These findings could have significant implications for human speech therapy and vocal training,” adds Coen Elemans.

Frequently Asked Questions (FAQs) about songbird vocal training
What does the new study about songbirds reveal?
The study highlights the importance of daily singing for maintaining vocal muscle strength in songbirds. It shows that without regular singing, these muscles weaken rapidly, affecting the songbirds’ attractiveness. The research also draws parallels with implications for human vocal training and speech therapy.
How does daily singing affect songbird attractiveness?
Daily singing exercises are crucial for songbirds to maintain their vocal muscle strength. Female songbirds prefer songs from males who engage in regular vocal exercises, suggesting that consistent singing enhances a songbird’s attractiveness in mating and social interactions.
What implications does this research have for humans?
The findings from the songbird study offer valuable insights for human vocal training and speech therapy. Understanding how vocal muscles in songbirds respond to regular exercise could inform techniques and approaches in human vocal muscle training and rehabilitation.
What was surprising about the songbird study’s findings?
Researchers were surprised to discover that songbird vocal muscles quickly lose strength and performance without regular use. In the study, the vocal muscles of songbirds weakened by 50% after just seven days of not singing, a rapid decline that underscores the ‘use it or lose it’ principle.
Who conducted the songbird vocal muscle study?
The research was conducted by an international team of scientists from the University of Southern Denmark, Leiden University, University of Umea, and the University of Vermont. The team was led by Assistant Professor Iris Adam and Professor Coen Elemans from the Department of Biology at the University of Southern Denmark.

huh, so the females actually prefer the songs of males who exercise more, nature’s got its own dating game going on there.
amazing research, who knew songbirds could teach us a thing or two about vocal training and therapy. great job by those scientists!
this is realy interesting stuff, never thought about how singing affects birds like that, shows how nature and humans are kinda similar?
Wow, didn’t know songbirds muscles get weaker so fast without singing, its like us going to the gym i guess.
