11 December 2017 - BALD EAGLES ARE COMMON IN ALASKAN TOWN


BALD EAGLES ARE 
COMMON IN 
ALASKAN TOWN

G'day folks,


The majestic bald eagle is the national bird of the United States, but most Americans are lucky to see one first-hand during their lifetimes. Unless they live in the town of Unalaska, Alaska, where bald eagles are as common as pigeons are in other human settlements.

Unalaska is home to around 4,700 people who have to share their space with over 600 beautiful bald eagles. It looks and sounds like something out of a fairytale, but it turns out that sharing your home with territorial predators also has its downsides. For one thing, you’re more likely to get attacked by a bald eagle in Unalaska than anywhere else in the US, and locals constantly have to keep an eye out for the birds, especially when going near their nests. They apparently hate it when people get too close.



 Bald eagles usually nest high up in trees, but the problem is that Unalaska doesn’t have too many trees, so the birds build their nests on cliffs on the edge of town or in man-made structures, which makes them more accessible to nosy humans. It’s easy to get a little too close to an eagle nest without even knowing it, which is why local law enforcement puts up warning signs all through the nesting season – from early June to the end of the summer. But even so, Unalaska sees between six and ten cases in which people require medical attention after encounters with eagles.

“We have these signs that we put up every year to remind people that there are nesting eagles in the area,” Deputy Police Chief Jennifer Shockley told Alaska Public Media. “They will do whatever it takes to protect their young, and that typically includes launching themselves at people and using their talons to lacerate their heads.”


 “We actually have had to go in and chase some eagles off the playground equipment at the town park, because a couple of kids had been trapped inside,” Shockley added.

But why are there so many bald eagles in this particular? Unalaska Island is almost 80 miles long, but the birds choose to live in an area of only a few square miles. Well, as you’ve probably already guessed, it has to do with food.

The Alaskan town is located right next to Dutch Harbor, one of the largest fishing ports in the world, and fish is a staple of the eagles’ diet. Every time a boat pulls in to offload, they swoop in and grab as much fish as they can get, before the crew drives them away.

 And then there is the local landfill, another favorite place to hang out for the local bald eagle population. They are scavengers, so they spend a lot of time looking for food through trash. Anything that even looks edible will catch their attention.


While the people of Unalaska love their eagles, many of them do consider them pests, kind of like people see pigeons in other places. They make a mess wherever they go, but whereas pigeons will run away when humans approach, bald eagles will attack you if they perceive you as a threat. The post office is famous as one of the most popular nesting places for the eagles, which also makes it a notoriously dangerous place to visit. A simple errand to mail a letter is likely to put in the hospital with deep flesh wounds.

 The sight of so many bald eagles in such a small town is especially impressive for newcomers. Seeing them perched on virtually every lamp post, looking for food in trash cans or just flying overhead with their wings fully extended makes quite an impact on people.

27 August 2017 - FACTS ABOUT THE EAGLE





FACTS ABOUT THE EAGLE

G'day folks,

Welcome to some quick facts about a bird I am always seeking to photograph.


Amazing Facts About the Eagle

Eagles are some of the largest birds. They are at the top of the food chain, with some species feeding on big prey like monkeys and sloths. Eagles have amazing eyesight and can detect prey up to two miles away.

How many species of eagle are there?

Eagles are birds of prey in the family Accipitridae; there are approximately 60 different species. The majority are found in Eurasia and Africa, with only 14 species found in other areas including North, Central and South America, and Australia.



What do eagles look like?

With the exception of some vultures, eagles are generally larger than other birds of prey. They have strong muscular legs, powerful talons and large hooked beaks that enable them to rip the flesh from their prey.

Eagles vary in size. One of the smallest species, the little eagle, is around 17.7–21.7 in (45–55 cm). In contrast, Stellers’s sea eagle is around 36–42 in (91–106 cm) in size, and wingspan can reach approximately 72–96 in (2–2.5 m).



 What do eagles see?

 

Sight is the strongest of all eagle senses. The eyes are large, can take up almost 50% of the head, and can weigh the same amount as a human eye. An eagles vision is 4–5 times better than that of a human. Eagle eyes are angled 30 degrees away from centre of the face, which gives eagles a greater field of view.  
Eagles can see five basic colours to our three, and can detect UV light.

Cones are light detecting cells that are sensitive to colour. One of the reasons that eagles have better vision than humans is because their retinas, a layer at the back of the eyeball, have more cones. We have 200,000 cones per square millimetre, whereas eagles have one million.



 Do eagles mate for life?

 

Eagles are monogamous, so generally mate for life. They have strong site fidelity, so a mating pair tend to reuse the same nest year after year. Nests, composed of sticks, vegetation, and downy feathers, are built by both males and females.

Location of the nest varies with species. Bald eagles for example, most likely nest in tall trees whereas as golden eagles prefer cliff faces or more open areas.



How many eggs do eagles lay?

The number of eggs laid will depend upon species, but many eagles lay between one and three eggs; four egg clutches do occur, but they are rare.

 What do eagles eat? 

 

Eagles are apex predators, meaning they are at the top of the food chain. What eagles eat depends upon the species and the food that is available to them, but they are all carnivorous and live on a diet of meat and/or fish.

Eagles can be divided broadly into four groups; sea eagles, booted eagles, snake eagles and giant forest eagles. Booted eagles have a relatively wide diet consisting of birds, small mammals, reptiles, rodents, amphibians and insects, whereas others are more restricted. Sea eagles or fish eagles feed mostly on a diet of fish whilst snake eagles specialise on capturing reptiles. Giant forest eagles feed on various forest animals. One of the largest eagles, the Harpy eagle, feeds on larger animals including monkeys, sloths and coatis.



Clancy's comment: Amazing birds, eh? And, the Eagles rock band is pretty awesome as well.
