The wintertime Bald Eagles are back at Jordan Lake North Carolina

Last week, I headed down to Jordan Lake in New Hill, NC to catch some Bald Eagle action. As usual, the birds did not disappoint!
Dropping out of the sky like darts, the Eagles put on an absolute clinic on how to catch the fish swimming in the icy river.
It was epic to watch them hit the water with a splash and come up with a wriggling fish. Their speed is breathtaking and for the older ones, their accuracy is astounding.

Bald Eagles use a couple of fishing techniques to fill their bellies during the winter.
Here on the Haw River, their favorite method is to perch in a tree and watch for a fish swimming in the water below, and then swoop down to capture it.
Just before they hit the water, the adult Eagles will pull their legs up into the classic C shape extending their talons in front of them to align their strike zone with the target fish below.
The immature birds are still learning this method so their legs tend to drag behind them resulting in missed strikes. With practice they’ll achieve the nearly 95% success rate that the adults enjoy.

After catching a fish the eagle will either fly back to a perching tree to eat it, or if the fish is small enough, swallow the meal whole while the bird is in flight. Occasionally, they’ll employ a second “fishing” technique by harassing one another in flight in order to get the successful hunter to lose his fish in midair.
Diving and nipping at at each other the aggressor will slam into the other bird in midair in an attempt snatch the fish from the other birds talons or in effort to get the other to drop the fish for easy pickings later.
It’s quite entertaining to watch and very interesting to note the difference between the hunting techniques of the experienced hunters vs. the newbies still learning the game.

Jordan Lake Dam: Migrating Bald eagles

A few weeks ago, I took a quick scouting visit to Jordan Lake to see how many Bald Eagles had arrived.
I was pleased to see a few dozen but was hoping that there would be more.



These gorgeous birds are really fun to watch hunt and squabble for a meal.
As seen in the last few photos in this post, sometimes they can lose a catch just by landing on the wrong branch at the wrong time lol!



Jordan Lake is home to more than 20 pairs of nesting Bald Eagles that call this beautiful lake home throughout the year.
The Haw River which flows out the lake to the south is host to a large population of migratory Eagles during the wintertime. From what I’ve observed in the past few years, this large flock can grow to 100 birds is mainly made up of un-paired adults and juveniles.

Adult Bald Eagles are accomplished anglers and are able to zero in on their prey from over 30 feet above the water.
Once they commit to a fish, they bring their legs forward curling their body into a C position as their talons line up in line with their eyes in a dead focused triangle. The precision displayed in the moment that they strike their quarry is remarkable!

With a catch rate numbering in the 10% range, the younger ones are still learning the fine art of fishing but it’s really neat to watch their skills progress over the season.
Most of their misses seem to come from the juveniles not bringing their legs up high enough to better focus that narrow the shot range.
As with the case with many of us, they will fail over and over again, learning along the way until they are as accomplished as their elders 😉

Bald Eagle breeding season is underway in North Carolina

By: Sally Siko- Admin Birdwatching NC

Last week, I had the opportunity to head down to Jordan Lake near Moncure, N.C. to photograph a flocking population of migrant Bald Eagles.
While snapping off some shots of a few juveniles fishing in the Haw River area, a pair of adults flew in and I got to see them swooping and sailing together right above the water.

With the breeding season underway here in central North Carolina, Bald Eagle behaviors change, as they shift from away from a largely independent life to living together as a couple.
This time period is known as “pair bonding,” and it’s a critical part of their breeding cycle.
As time passes, their courtship intensifies with both birds engaging in incredible aerial displays.
Bonded pairs will fly high in the air, lock talons, and fall toward the earth, holding together as the ground approaches, and releasing just in time to avert disaster.
It’s one of nature’s most awesome sights, and more that a little dangerous.
So what’s the point of this of risky behavior?


Bald Eagle courtship rituals reinforce the pair’s commitment to each other, which is important for propagation of the species.
After all, they need to stick together to hatch, feed and care for their young.


A less obvious (but interesting!) thing about Bald Eagle courtship displays is that they actually stimulate the birds so they release the appropriate hormones to optimize egg fertilization once copulation takes place.


Love is in the air, indeed 😉

Bird watching N.C. News : A new Bald eagle nest has been confirmed at Jordan Lake Park

By: Sally Siko- Admin Birdwatching NC

Nest update! I’m pleased to report that this morning, I was able to confirm that the nest site that I found a few days ago at Jordan Lake is indeed a brand new Bald Eagle aerie.
I watched the pair for a little over an hour as they moved in and out of the nest before one took off and flew out of sight (to hunt I suppose). The remaining bird ended up sitting on a bare branch preening in the sun till his mate returned.



Bald Eagles lay between 1-3 eggs per clutch but I don’t believe this hen has laid their eggs yet due to her behavior at (and away from) the nest.
When the time comes, their eggs will be laid about 3 days apart, with incubation beginning with the laying of the first egg.
This offers full protection to the entire clutch from predators and to ensure that the eggs don’t hatch at the same time.


Each individual egg takes 35 days of incubation — give or take a few hours which means that the chicks will hatch 3 days apart.
This odd laying pattern is to facilitate the success of the healthy development of at the very least, one Bald Eagle chick. When prey is scarce, the strongest of the brood (usually the first hatched) will end up eating most or all of the food due to its 3 day growth / strength advantage over its siblings.
Sadly, this means that in leaner times, 1 or 2 of the chicks per brood will not make it to fledge status. In times where prey is plentiful, all of the chicks will have a good chance of survival under the care of their parents.



Luckily, the food supply here at Jordan Lake seems to be plentiful which lends itself to higher rates of success of the number of eaglets growing into adulthood here in this special place.
