  • Female birds may have lost desire to sing due to predation
    Malurus cyaneus is a Southern Hemisphere songbird males and females provision the brood and produce solo song year round Both sexes had higher song rate during the fertile period and lower song rate during incubation and chick feeding Females were more likely than males to sing close to or inside the nest For this reason female but not male song rate predicted egg and nestling predation This study identifies a high fitness cost of song when a parent bird attends offspring inside a nest and explains gender differences in singing when there are gender differences in parental care Journal reference Biology Letters 805 shares feedback to editors 2016 Phys org Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 Scientists discover hidden galaxies behind the Milky Way Feb 09 2016 3 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 more Phys org on facebook Relevant PhysicsForums posts The great basic question of science on origin of life 1 hour ago How to create microscope videos 1 hour ago Fly feeling 11 hours ago Why do you get pressure drop in central circulation 11 hours ago Novel Idea on the Origin of Life 12 hours ago Opening the blood brain barrier with collapsing bubbles 21 hours ago More from Biology and Medical Related Stories Warbling wrens don t just tweet they sing duets November 3 2011 AP They may not be Sonny and Cher but certain South American birds sing duets taking turns as the tune goes along Calling it a love song is probably too strong a word says researcher Eric S Fortune of Johns Hopkins Bird song it s not just a male gig March 5 2014 Since Darwin s observations we thought that bird songs were a male trait for courting with females who were drawn to the most seductive male song Nightingales show off their fathering skills through song June 18 2015 The song of the male nightingale tells females how good a father he will be according to research published in the open access journal BMC Evolutionary Biology Late hatched canaries learn their songs as well as early hatched birds August 26 2015 Most songbirds learn their songs from their father or other male conspecifics The variables that control the song learning process in a natural social environment are still largely unknown Scientists from the Max Planck In cordon bleus song develops independently of sex differences in the brain November 4 2015 In female songbirds brain areas responsible for song learning are usually smaller and have fewer neurons compared to males However in many species such as the blue capped cordon bleu females possess an elaborate song Researchers reveal acoustic complexity of chickadee songs November 5 2015 Songbirds join humans in the select few animal groups that
