Avian expert warns migratory birds are facing annihilation

Millions of migratory birds that fly tens of thousands of kilometres between their homes in Australia and Siberia are facing annihilation as development destroys the vital feeding grounds they rely on during their epic journeys, a Deakin University avian expert has warned. Director of Deakin’s Centre for Integrative Ecology Professor Marcel Klaassen has joined a … Continue reading

When David beats Goliath: Smaller birds can dominate larger species

When David beats Goliath: Smaller birds can dominate larger species

  When it comes to body size, larger species usually win out over smaller ones. Yet occasionally, there’s a case of David beating Goliath. Now one biologist has found that sometimes small species of birds can dominate larger species during aggressive interactions, especially when they interact with distantly related species. “We want to understand why … Continue reading

Audubon Releases Comprehensive Study On Climate Change Impact On Birds

If you like hearing the loon’s call at the lake or spotting ducks, you could be out of luck in the near future. In a first-of-its-kind study, Audubon has released a comprehensive study of bird species throughout Alaska, Canada and the continental U.S. assessing fundamental climate needs for each species to survive. It found several … Continue reading

Study says bird brains more precise than humans’

Study says bird brains more precise than humans’

  Birds have been found to display superior judgement of their body width compared to humans, in research to help design autonomous aircraft navigation systems. A University of Queensland (UQ) study has found that budgerigars can fly between gaps almost as narrow as their outstretched wingspan rather than taking evasive measures such as tucking in … Continue reading

Research identifies drivers of rich bird biodiversity in Neotropics

Research identifies drivers of rich bird biodiversity in Neotropics

An international team of researchers is challenging a commonly held view that explains how so many species of birds came to inhabit the Neotropics, an area rich in rain forest that extends from Mexico to the southernmost tip of South America. The new research, published today in the journal Nature, suggests that tropical bird speciation … Continue reading

Migrating birds sprint in spring, but take things easy in autumn

Migrating birds sprint in spring, but take things easy in autumn

Passerine birds, also known as perching birds, that migrate by night tend to fly faster in spring than they do in autumn to reach their destinations. This seasonal difference in flight speed is especially noticeable among birds that only make short migratory flights, says researcher Cecilia Nilsson of Lund University in Sweden, in Springer’s journal … Continue reading

Nighttime Lights Reset Birds Internal Clocks

Nighttime Lights Reset Birds Internal Clocks

Streetlights and the light from shopping centers, stadiums, and houses turn night into day, a “loss of night” that is shifting the internal clocks of birds worldwide. Now, scientists are trying to understand how artificial lights are affecting birds’ songs, mating, and reproduction. High on bluffs overlooking the Pacific, Dominik Mosur was strolling along at … Continue reading

Burnt out birds suggest hard work could be bad for your health

Burnt out birds suggest hard work could be bad for your health

Unequal sharing of workloads in societies could leave the most industrious individuals at higher risk of poor health and prone to accelerated ageing, according to a new study of a cooperative bird in the Kalahari Desert. A team of scientists at the University of Exeter studied white-browed sparrow weavers, a social species in which all … Continue reading
