Biologists Marin Moravec, Professor Nancy Burley and Professor Georg Striedter conducted the study, which was published in Ethology in early November. The study also found that males that paired with more similar-sounding females gave more help to the females when they were nesting.
Budgerigars, small Australian parrots commonly kept as pets, produce highly variable contact calls. Previous research showed that male budgerigars spontaneously imitate the calls of females that are potential mates. In addition, females were known to prefer males that had been trained to produce calls similar to theirs. The current study is important because it shows that female budgerigars preferentially pair with males that sound like them at their first meeting, before any imitation has occurred.
Parrots display a gift, rare among most animals, of learning new vocalizations throughout their lifetime. A highly social, monogamous species, the budgerigar likely uses multiple aspects of vocalizations when choosing mates and maintaining long-term relationships. This study adds to our understanding of the social functions of vocal learning. It also provides an interesting avian example of a familiar mate choice strategy: choosing a mate with whom you have something in common.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
