Bad reputation of crows demystified

Bad reputation of crows demystified

In literature, crows and ravens arebad omens and are associated with witches. Most people believe they steal, eat other birds’ eggs and reduce the populations of other birds. But a new study, which has brought together over 326 interactions between corvids and their prey, demonstrates that their notoriety is not entirely merited. Corvids—the bird group … Continue reading

Bird ‘paints’ its own eggs with bacteria to protect the embryo

Bird ‘paints’ its own eggs with bacteria to protect the embryo

Researchers from the University of Granada and the Higher Council of Scientific Research (CSIC) have found that hoophoes cover their eggs with a secretion produced by themselves, loaded with mutualistic bacteria, which is then retained by a specializad structure in the eggshell and which increases successful hatching. So far this sort of behaviour has only … Continue reading

Riddle of flying bird’s weight solved by scientists

Riddle of flying bird’s weight solved by scientists

Scientists at Stanford University in the US have developed a super-sensitive device that can measure the weight of a bird in flight. The invention, created by Prof David Lentink’s research team, measures the force produced by every wing flap. The device, described in the Royal Society journal Interface, will enable researchers to carry out tests … Continue reading

Are human behaviors affecting bird communities in residential areas?

Are human behaviors affecting bird communities in residential areas?

A new study from the Wildlife Conservation Society shows that habitat alteration may be less important than other factors- such as human behavior- in driving the effects of “exurban” development on bird communities. These unexpected results are fueling more questions that may ultimately lead to informed landowners lessening their impacts on local wildlife. Exurban development … Continue reading

Researchers able to perform extended study of stunning wild northern cardinal gynandromorph

  Ornithologists Brian Peer and Robert Motz, with Western Illinois University, found themselves with a unique opportunity a couple of years ago—to study a gynandromorphy in its native environment for an extended period of time. They have written a paper describing what they observed and have had it published in The Wilson Journal of Ornithology. … Continue reading

Drought causes birds to nest later, reducing nesting success

Drought causes birds to nest later, reducing nesting success

A recent study suggests drought conditions are delaying nesting by two weeks or more for some Sonoran Desert bird species, such as Black-tailed Gnatcatchers and Verdins. Despite recent rainfall, drought conditions persist in much of the southwestern U.S. Drought negatively impacts, many wildlife species, making it harder to maintain their numbers, even when adapted to … Continue reading
