and once-polluted industrial wastelands now chirp with birdsong, rivers swim with fish and populations of animals that have become rare in the countryside are thriving in urban niches.
song birds lose some of their brain cells. The cells that allow the birds to learn songs commit suicide only to be replaced by newly grown cells.
This is interesting because brain cells arent supposed to be regenerative, and these so-called precursory cells are native to the bird brain.
so the birds can learn new songs. http://www. news. harvard. edu/gazette/1998/04. 16/Experimentsrais. html 4. Using immature cells from the brains of mammals to replace dead
We dont need to regenerate brain cells to learn new songs, but we do need a cure for Alzheimers disease and Parkinsons disease.
birds have to use songs that can cope with this#.#Birds living in urban areas sing at a higher pitch to reduce the impact of echoes from surrounding buildings, a study claims.
Higher-pitched songs travel further in built-up areas because their echoes fade more quickly, meaning the following notes are clearer and easier to pick out.
and other common birds raised their pitch in urban areas to distinguish their song from the low-pitch drone of traffic and machinery,
birds have to use songs that can cope with this#.#The study, published in the PLOS One journal, also found that urban birds songs were heard more clearly in woodland than those of forest-dwelling birds,
possibly because rural birds use clues like how muffled songs are to determine their distance from one another.
Dr Rupert Marshall, another of the researchers, added: In woodland where trees and leaves obscure the view,
many species of songbird can tell how far away a rival is degraded by how its song is.
and song doesn t degrade as quickly, so city birds may just concentrate on being heard.##Via Telegraph Share Thissubscribedel. icio. usfacebookredditstumbleupontechnorati T
 A female blue tit which is about the size of an adult hand from beak to tail picks her partner based on his colorful blue and yellow plumage and the sweetness of his song.
How Bees Do it There are quite a few allusions to the phrase in literature and song. One of the early references to this bird and bees as a euphemism for reproduction is Samuel Taylor Coleridge's 1825 poem oework Without Hope:
How Birds Do it A more direct reference can be found in Cole porter's lyrics to the 1928 song Let's Do it.
agrees behavioural neuroscientist Juli Wade at Michigan State university in East Lansing who works on sexual differentiation in the songs of zebra finches2.
The band Superhuman Happiness recorded a new song and music video with the Treequencer. Someday Shaffer and his colleagues hope to waterproof their invention add solar panels to power it
or the zebra finch used in the Jove article are unique as they provide a landscape for scientists to study song acquisition storage and regurgitation.
In addition they played back recorded songs of randomly selected warbler males from the area. The scientists then observed nest building activity and feeding of offspring and determined chick paternity through DNA analyses.
which aren't learned like songbird songs or human speech the researchers say. We still do not know why a dog says'bow-wow
#How human language could have evolved from birdsong: Researchers propose new theory on deep roots of human speechthe sounds uttered by birds offer in several respects the nearest analogy to language Charles darwin wrote in The Descent of Man (1871)
first the elaborate songs of birds and second the more utilitarian information-bearing types of expression seen in a diversity of other animals.
Based on an analysis of animal communication and using Miyagawa's framework the authors say that birdsong closely resembles the expression layer of human sentences
Birdsong lacks a lexical structure. Instead birds sing learned melodies with what Berwick calls a holistic structure;
the entire song has one meaning whether about mating territory or other things. The Bengalese finch as the authors note can loop back to parts of previous melodies allowing for greater variation and communication of more things;
and then managed to integrate specific lexical elements into those songs. It's not a very long step to say that what got joined together was the ability to construct these complex patterns like a song
but with words Berwick says. As they note in the paper some of the striking parallels between language acquisition in birds
Well in birdsong there is also this limited number of beat patterns. Birds and beesthe researchers acknowledge that further empirical studies on the subject would be desirable.
but the male sings one of the loudest songs on the planet says Yale's Rick Prum.
Particularly fit males start to sing pre-dawn songs. We also know that female blue tits tend to be unfaithful to their partners
