A recently published study reveals that climate change can cause birds’ eggs to hatch early. In addition to creating warmer temperatures that trigger early embryonic development in birds, climate change also increases the frequency and duration of heat waves. Thus, warming temperatures are leading to asynchronous hatching of individual eggs within a clutch and increased chick mortality, particularly for birds breeding in the tropics and semi-tropics, and in tropical deserts.

A recently published study of captive-bred whooping cranes found that young birds learn their migration routes over many years, and migrating alongside older birds improves the migratory efficiency of younger birds.

A Monkey Economy is as Irrational as our Human Economy. Why do people make irrational decisions in such a predictable way? Laurie Santos looks for the roots of human irrationality by watching the way our primate relatives make decisions. This video documents a clever series of experiments in "monkeynomics” shows that some of the silly choices we make, monkeys make too.

Common Ravens have been shown to express empathy towards a "friend" or relative when they are distressed after an aggressive conflict — just like humans and chimpanzees do. But birds are very distant evolutionary relatives of Great Apes, so what does this similarity imply about the evolution of behavior?

A recently published study, intended to provide data to commercial fisheries in the Gulf of Mexico so they maximize their catch of Yellowfin Tuna, Thunnus albacares, whilst avoiding bycatch of critically endangered Atlantic (Northern) Bluefin Tuna, Thunnus thynnus, suggests that the Deepwater Horizon oil leak may devastate the endangered Atlantic bluefin population, causing it to completely collapse or possibly go extinct.

An Australian Aboriginal rock art may depict a giant bird that is thought to have become extinct some 40,000 years ago, thereby making it the oldest rock painting on the island continent. The red ochre drawing was first discovered two years ago, but archaeologists were only able to confirm the finding two weeks ago, when they first visited the remote site on the Arnhem Land plateau in north Australia.

While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens , only to discover that it had the longest migratory journey of any insect in the world.
