Despite being one of the most threatened species on the International Union for Nature Conservation (IUCN)’s red list, the Spanish imperial eagle (Aquila adalberti) is recovering in Spain. The species has undergone an increase from 38 pairs in 1974 to 253 in 2008, data viewed as hopeful by the scientists who carried out the demographic study on the Iberian Peninsula. “This study shows that the species has recovered and has responded well to conservation initiatives. Although it has been known for a long time, the study shows once again that this species is highly affected by changes in adult survival rates”, Santi Mañosa, one of the authors of the study and a researcher at the University of Barcelona, tells SINC.

Some of the most important reasons behind the failure of the Spanish imperial eagle (Aquila adalberti) to increase its numbers have been premature adult deaths resulting from electrocution on electricity lines and the consumption of poisons used to control predators.

South of Eureka Springs, Arkansas and not far from Rogers, Arkansas, War Eagle Cavern provides visitors a chance to tour a cavern in a nearly natural state. War Eagle Cavern is located in Northwest Arkansas on Beaver Lake. The cavern may be reached by both land and water. Highway 12, a scenic state highway, leads visitors by road through the curves of the scenic Ozark Mountains. The visitor who is inclined to spend time on the water may boat on Beaver Lake to Devil’s Gap Inlet and follow signs to the War Eagle Cavern Docks.

Imagine a room decorated with unconventional objects of art, such as a calf leg and a rabbit spine. The finishing touches include a number of large, artistically placed feathers. Is this the latest episode of a home makeover show? Nope. Just the real-life nest of a fastidious California Condor named Paxa. One of 19 condor residents at the Oregon Zoo, Paxa is part of a pivotal program to save the California Condor from extinction.

In 1987, only 17 condors remained in the wild. The San Diego Zoo was the first breeding program to undertake the urgent mission of saving this bizarre-looking bird. In 2001, the Oregon Zoo became the fourth partner in the California Condor Recovery Program (CCRP). With the 2003 arrival of condors at the Oregon Zoo and the birth of a chick six months later, a century-long void in Oregon-born condors came to an end.

Haliaeetus leucocephalus or bald eagles, ranges throughout North America except in the very far north. And It is the national emblem of the United States. Bald Eagles are fish, or sea eagles, so called because they’re skilled at catching fish, as well as sea birds and small land mammals. (They also feed on carrion and may steal prey from other raptors.) While the species is seen almost everywhere in Canada, the United States, and northern Mexico, larger populations congregate in coastal areas.
Most Bald Eagles breed in the northern part of their range, building enormous nests in areas where food is plentiful. They are long-lived birds, surviving up to fifty years in captivity, but less in the wild where they face many more threats.

What is the home-range of the Bonelli’s eagle? Do males and females share territories? Do patterns of spatial use vary during the year? A study led by the UB’s Conservation Biology Group provides new information on spatial patterns of the Bonelli’s eagle (Aquila fasciata), an emblematic species of the Mediterranean area and considered endangered across Europe. The study, published in the international journal The Ibis, provides new data on the spatial use of the species which reveal valuable new ecological information and will form the basis of new territorial conservation and species management strategies.

“The classical approach of protecting only the breeding areas is no longer sufficient,” explains Joan Real, head of the Conservation Biology Group, who argues that, “We also need to protect areas further from nesting sites but ideal for hunting, as these are key to the survival of territorial individuals.” The article, which explains that Bonelli’s eagles often use areas that have great biological value but are generally unprotected, is the fruit of a project supported by the Barcelona City Council and the Spanish Ministry of Education and Science.
