Researchers Find Active Harpy Eagle Nest in Maya Mountains of Belize

Jamie Rotenberg, UNC Wilmington assistant professor of environmental studies, along with researchers at the Belize Foundation for Research and Environmental Education (BFREE), is studying what is thought to be the first active Harpy Eagle nest ever recorded in Belize, where the predatory birds were previously thought to be extinct.

Two adult Harpies and one five-week old nestling were discovered in November, when Belizean technicians were patrolling the Bladen Nature Reserve in the Mayan Mountains of Belize. The area is rugged and remote, but scientists have searched for signs of the bird there since 2005, when an adult was first spotted.

Harpy Eagles are known as the most powerful raptor in the Americas, weighing up to 20 pounds and reaching a seven-foot wingspan. They hunt prey as large as monkeys and sloths for food. However, due to deforestation and hunting, Harpy Eagles are typically missing from most of Central America's rainforests, where they once freely ranged. They are designated as "Near Threatened" by the International Union for Conservation of Nature (IUCN) and considered "Critically Endangered" in Belize.

It's currently unclear how or why the birds managed to nest in the area. According to Rotenberg, the active nesting site is a sign that the reserve is functioning to keep wildlife safe from dangers associated with human interference.

"Biologically, the presence of the Harpy pair and chick signifies an in-tact eco-system that extends to the highest predator," Rotenberg says.

Following the spotting in 2005, BFREE, in conjunction with Rotenberg, submitted a grant proposal to The Nature Conservancy Belize Program, proposing an innovative science-based program that would focus on avian conservation and awareness. Funded in 2006, the Integrated Community-Based Harpy Eagle and Avian Conservation Program links Belizeans to the protected areas of land adjacent to their homes through specific environmental awareness projects. Belize is a small, English-speaking country about the size of Massachusetts, with approximately 40 percent of its lands protected in reserves and parks.

Recently, the program has grown to include collaboration with The Institute for Bird Populations in California, BioDiversity Research Institute in Maine, and York University in Canada. Rotenberg has taken approximately 50 UNC Wilmington students to Belize to work with BFREE as part of the study abroad program he offers. Undertaking undergraduate internships as well as master's level projects, students have worked closely with the bird study site and the community awareness program.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'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...
