‘Female Fairywrens Sing To Their Eggs’ And Eight More Facts About Birdsong

"From carolling magpies to the lullaby of fairywrens, the nature and purpose of birdsong is more varied than you might think" 

"Birdsong seems to be always around us, but have you ever wondered why they sing? For more than 10 years, I have been studying birds and am constantly fascinated by them and their song. I want to share with you some amazing facts I learned.

Songbirds belong to the order Passeriformes, making up more than half of all bird species in the world. That’s nearly 5,700 species! These are among the most abundant birds found on nearly every terrestrial location on Earth. Their song is one of the most complex signals in the animal world and has always fascinated humans.

As female songbirds in Europe and America don’t sing, this led to the assumption all female birds don’t sing. Male songbirds such as the European blackbird will sing in the early morning to mark their territory, letting others know he is still present. If he hasn’t secured a mate, he will also sing to attract a female. For a listening female, male song can be viewed as honest signals – conveying useful information about the singer’s physical health."
