Rare 'itinerant breeding' behavior revealed in California bird

Only two bird species have ever been shown to undertake what scientists call 'itinerant breeding': nesting in one area, migrating to another region, and nesting again there within the same year, to take advantage of shifting food resources. However, new research provides strong evidence of this rare behavior in a third bird — the Phainopepla, a unique bird found in the southwestern US and the northernmost member of an otherwise tropical family.

The impact of human-caused noise pollution on birds

October 11, 2019 0 Comments Birds, Endangered Animals, Extinction, Life Sciences, Mating and Breeding, Nature, New Species, Wild Animals

Anthropogenic noise pollution (ANP) is a globally invasive phenomenon impacting natural systems, but most research has occurred at local scales with few species. Researchers in this study investigated continental-scale breeding season associations with ANP for 322 bird species to test whether local-scale predictions are consistent at broad spatial extents for an extensive group of North American bird species in the continental United States.

Plant death may reveal genetic mechanisms underlying cell self-destruction

Hybrid plants, which produced by crossing two different types of parents, often die in conditions in which both parents would survive. Certain hybrid tobacco plants, for example, thrive at 36 degrees Celsius, but die at 28 degrees Celsius, which is the temperature at which both parents would thrive. Researchers have begun to unravel the molecular mechanisms by which hybrid tobacco plant cells meet their demise.

Daddy daycare: Why some songbirds care for the 'wrong' kids

Interspecific feeding — when an adult of one species feeds the young of another — is rare among songbirds, and scientists could only speculate on why it occurs, but now, researchers have new insight into this behavior.
