Sea eagle couple in Lauwersmeer gets twins

Today, 13:56

The sea eagle couple of the Lauwersmeer national park got two youngsters this year. Yesterday, the Forestry Department spotted both young additions, RTV Noord regional TV writes.

Over the last three years, breeding failed twice. Last year was better, the eagle couple got one eaglet.

“The last time we had two young birds here was in 2013,” says forester Jaap Kloosterhuis.

The Forestry Department observes the birds from a distance. “We can and do not want to get too close. We follow them with a telescope.”

The youngsters do not look that young any more. “They already have feathers,” says Kloosterhuis. Therefore, they will likely be ringed soon.

The foresters will discuss when to ring the eaglets this afternoon. Young birds are ringed when their legs have become fully grown, so that the rings will not harm them.

Warden Bertwin Bergman of Oostvaardersplassen national park reports that local white-tailed eagle twins have been ringed today. There, in 2006, sea eagles nested for the first time in the Netherlands after centuries of absence. Ever since 2007, Oostvaardersplassen eaglets have been ringed; so, today was the 11th time.

In the Oostvaardersplassen nest, there were carp, coot and grey lag goose meat scraps. So, the eaglets have a varied diet.

First ever young ses eagle hatched in Dutch Groningen

This 12 May 2017 Dutch regional broadcaster RTV Noord video is about conservation organisation Het Groninger Landschap officially notifying Haren local authority, which includes Hunzedal nature reserve, of the birth of a young white-tailed (aka: sea) eagle.

Dutch Dagblad van het Noorden daily reported on 9 May 2017 that the first ever young sea eagle of Groningen province hatched in the Hunzedal nature reserve, close to the Zuidlaardermeer lake.

Sea eagles had been extinct in the Netherlands for centuries but came back as nesting birds ten years ago.

The Hunzedal parents are a young couple which had already been in the area for years. This spring it was their first egg. In this area live otters, beavers and rare birds like white-winged black terns as well.

Ex-drug addicts help saving Philippine eagles

The Magnificent Philippine Eagle Nesting in the Wild

23 January 2014

This is a rare video of one of the most critically endangered and least photographed raptor in the world feeding its eaglet. This is the first time that an organization namely the Wild Bird Photographers of the Philippines, Inc. was authorized by the government through the Biodiversity Management Bureau of DENR to document this majestic eagle.

Former drug users turn conservationists to save the Philippine Eagle

Former drug users, indigenous people and conservationists form an unlikely team for the noblest of causes: restore the forest where the Haring Ibon lives. And it’s a success.

By Albert Balbutin & Luca Bonaccorsi

Drug addicts, members of the Dumagat ethnic group, and local conservationists. It is rather eclectic, this bunch of people crossing the River Dupinga. The locals know the river all too well, and fear it. It brings water and fish, life really, if the weather is good. But with copious rains it quickly turns into a merciless killer with flash-floods and mudslides.

We are in Luzon, the largest and most intensely populated island of the Philippine archipelago (roughly half the land area of the UK but with the same population).The Dumagat, one of the Philippines’ Indigenous Peoples who call the forest their home, were once hunter-gatherers and nomadic. With the forest offering less and less they live now impoverished, often thanks to small jobs with lowland dwellers.

The drug users belong to the group that has accepted to change their way of life. Here, in the midst of the highly controversial war on drugs” that has seen an escalation in illegal killings and death squads, they call them “surrenderees”.

The conservationists are members of the Haribon Foundation (BirdLife in the Philippines) and worship this place since it’s one of the last habitats of the majestic Philippine Eagle Pithecophaga jefferyi (Critically Endangered).

It’s in the name of the charismatic “King of the Birds”, Haring Ibon, and its forest, and thanks to the intervention of the local government of Gabaldon, that these three very different groups of people have come together.

Their mission? Get the “drug surrenderees” to plant high-value fruit trees not too far away from where Philippine Eagle sightings have taken place as part of their community service.

And in order to plant mango, rambutan, guyabano, langka, and coffee, as well as native trees such as narra and duhat, the forest knowledge held by the Dumagat, and the conservationists, is much needed. “Forest restoration is what Gabaldon needs. It is an investment that could save the future generations of the municipality”, says Sam Manalastas, Community Organizer for Haribon.

For months now Manalastas has been working with Dumagat members and other sectors in the town of Gabaldon to come up with a Critical Habitat Management Plan. The plan involves five years of conservation actions to help protect the Haring Ibon of Mt. Mingan, which lives not too far from the fast-growing municipalities in the lowland areas of Gabaldon and San Luis in the Aurora province.

“By planting trees,” adds Manalastas, “they are helping not only the biodiversity of Mt. Mingan, but also their municipality in becoming resilient against climate change.

”As the present administration’s war on drugs continues in many areas of the country, the public remains divided on what to expect. With killings still taking place, some groups support the call to arms against drugs and the crimes associated with it, while others declare it an assault to human rights and the judicial process.

The trek to the planting site is not the easiest one: a river to cross, rough terrain, steep hills. Puffing and panting up a grassy hill, the former addict is probably having second thoughts about his “healthy rehab”, but then he smiles at the view and pushes on. By the end of the day, their foreheads wet with honest work, mission is completed. For the local government the initiative sends a strong message: the area is safe.

For the Dumagat a good pay, the recognition of their forest wisdom and a step towards inclusion. For drug users a chance to change life (and get home safe). For conservationists a small contribution to the health of Mt. Mingan, home to the King of the Birds. The most obvious of win-wins. Conservation has done it again.

Golden eagle migration in bad weather, new research

Eagles migrate through bad weather to arrive in time to nest

April 5, 2017

Migration is tough, and birds do everything they can to optimize it. How do factors like weather and experience affect the strategies they choose? A new study from The Auk: Ornithological Advances shows that older, more experienced Golden Eagles actually migrate in poorer weather conditions and cover less ground than their younger counterparts, but for a good reason — they’re timing their efforts around raising the next generation of eagles.

Adrian Rus of Boise State University (now at Australia’s University of Sydney), Todd Katzner of the USGS, and their colleagues studied GPS telemetry tracks to evaluate the migratory performance of almost 90 Golden Eagles in eastern North America and determine how performance related to season, age, and weather. Unsurprisingly, eagles flew faster and farther when they had strong tailwinds and thermals to help them along. What was counterintuitive, however, was that older eagles did not cover more ground than younger eagles despite their greater experience. Instead, older eagles migrated in poorer weather conditions and travelled more slowly.

The researchers believe this is because older birds face different pressures than younger birds. Even if the weather is bad and will slow them down, they need to start heading north earlier than young birds that aren’t breeding, because they have to get back to their breeding grounds in time to reclaim their territories and start nesting. “Younger eagles just need to survive the summer, so they can be choosy about when they travel north and only migrate when conditions are really ideal for fast soaring flight,” explains Katzner.

Lead author Adrian Rus, who worked on the study as an undergraduate, enjoyed the challenges involved in analyzing the migration data. “The best part about working on this project was using specialized software to visualize the golden eagle migrations and being able to pair it with meteorological data to answer my biological questions,” he says. “As a result, the project greatly improved my geospatial and statistical analysis skills and was instrumental my current graduate research in animal movement ecology.”

“Rus et al. provide an unusual demonstration of the interaction between migration experience and seasonal environments,” according to Oklahoma University‘s Jeff Kelly, an expert on avian migration. “It is likely that the migration experience that older birds have enables them to extend their summer season through early spring and late autumn migration despite declining atmospheric conditions. Rus et al.’s demonstration of this insight into the interaction between age and the migratory environment expands our thinking about the life history tradeoffs that occur across the annual cycle of migrants.”
