![]() ![]() They use it to attract females and stake out their territory. During the spring breeding season these songs can be heard from birds. The birds use these calls to converse (contact calls) or to warn each other of danger (warning calls). Calls are called the chirping that you hear all year round. The American Robin, however, is a member of the Turdidae or thrush family, and is not closely related to the Old-World robins it was given its name by the early settlers from Europe because its reddish-orange breast plumage reminded them of their familiar garden companion.There are two different types of birdsong: calls and songs". Many of the Old-World robins are now grouped under the flycatcher family, but were once considered thrushes. Bush, scrub and forest robins occupy parts of Europe, Africa and Asia. The European robin, as the name suggests, is found throughout Europe, but also Siberia and North Africa. It was given its name by the early settlers from Europe.Īustralasian robins, however, are only distantly related to the European robin, and some do have red breasts, but there are also yellow and white breasted robins as well as the charming pink and black robins. Small birds with a compact build, a large, rounded head, a short, straight bill, and rounded wingtips can be seen in most of the Old-World species. Many species have been classified and reclassified as genetic mapping has advanced, but physical similarities do explain the naming in most cases. Jays are noisy and quarrelsome birds, and the word “jay” was once a popular American slang word for people who rudely chatter away.The term jaywalking describes the act of wandering stupidly into roads and causing traffic accidents, again a nod to the bird’s seemingly reckless behaviour of abrupt noisy flapping from tree to tree. JAYS Jays comprise several species from the corvid family, and inhabit both the Old and New World, with far more species living in the Americas. ![]() ![]() All other species of true wren live in the Americas, a remarkable fact now that we know their ancestors originally lived almost 10,000 miles away.Ģ. These characteristics are not genetic, however, and these birds are actually close relatives of honeyeaters. New Zealand and Australian wrens are not related to true wrens at all, and their naming appears to have simply come from their similarity to Old World wrens in size, shape and behaviour – and certainly not plumage some fairywrens exhibit the most startling combination of blacks, blues and purples, earning them names such as “splendid” and “superb” fairywrens. The Eurasian wren inhabits Europe, Africa and Asia and is the only true wren species found in the Old World, and is simply known as “wren”, indicating its alleged original ownership of the name. Their Latin name refers to this furtive brown bird’s propensity to forage and skulk about in dark crevices – troglodyte means cave dweller. ![]() WRENS The family Troglodytidae comprises 88 species of wren. Below we look at just three types of songbirds from the many thousands that managed to cross the waters to new beginnings in distant lands.ġ. The first songbirds in Asia had arrived, and their spread to the rest of the world had begun. The genetic changes in songbirds have been traced to this same timeline: a corridor of passage, like stepping stones from one side of the river to the other, enabled species to land-hop to different niches, and adapt to their new surroundings. Courtesy of Wikimedia Commons.Ībout 24million years ago, the Wallacea group of islands cropped up in the oceanic gap left as Australia and Asia formed, drifting apart over millions of years. 65% of the world’s bird species all originated on the continent we now call Australia.įinding that all songbirds have a common ancestor in Australia immediately presented questions like, how did they get all the way over to the other side of the world, and why are some species now only found thousands of miles away?Įurasian wren. Until this discovery, it was widely believed that birds established themselves on various land masses after movement was triggered by factors like solar radiation,population bursts and so on it is now the belief that birds were merely passengers on the ever-shifting geography, that the world moved them as tectonic forces and volcanic eruptions reshaped the earth beneath their four-toed feet. Previous theories supported the view that these perching birds had originated in South America, but by using technology that has only become available in the last decade or so, genetic evidence has now been uncovered that shows the lineage of some of our most familiar songbirds originated between 30 and 47million years ago Down Under. ![]()
