Hello - Our first question from the class is:

If there is another eagle in the area, could it be one of their previous eaglets?

Would they know if it was?

Hello 3rd graders welcome!

What a great question.  :ecsmile. There are many bald eagles on Hornby Island. This is a link to a map of nests known there.
http://www.ournaturezone.com/index.php?topic=54.msg37531#msg37531

Some of these eagles could be offspring of Mum and Dad Hornby. Although you noticed yesterday that they don't allow other eagles in their territory, especially during nesting time. We have noticed however that there is a juvenile ( young) eagle that does not seem threatening to Mum and Dad and they allow it in their territory, but not at the nest itself.

Here is a link to our ground observation crew's topic and specifically re: this eagle is thought to be 2 year old "Hope", one of Mum and Dad's eagles.

Start here for pictures and story of the March 12,2011 sighting. There are many posts

Question today from our third graders.


Hi Beth,

My class is wondering what would be the heaviest weight of food an eagle could bring to the nest?

I know last year the opposum was brought in.

The slide show site we were sent to yesterday with the juvenille eagle was absolutely wonderful.
The kids really enjoyed watching it. We have a large Smart Board in our room and the slides were beautiful.

I think that an adult eagle can carry something as heavy as 4 pounds. (I will confirm this but want you to have an answer now.)


Added: Yes, a very strong, adult eagle can carry up to four pounds. A lot would depend on how far it tried to fly with it.

Hi 3rd grade,

If an eagle catches a fish that is too heavy, sometimes they swim to shore, using their wings the way we do a Butterfly stroke.   :thumbup:

If the fish or other food they find is too heavy to fly with it up to the nest, they can eat some first and then take parts of the rest to the nest. 

Mom and Dad Hornby sometimes do that with opossums they find and bring back for the little eaglets to eat.

A video has been posted for you to watch. 

DAD FEEDS THE EAGLETS on May 13, 2011  click here

This is a video of Dad Hornby feeding David and Alexandra. He carefully tears the meat into small pieces for them but you will see in this video that David got a long stringy piece and had a hard time getting rid of it.  :ecsmile Dad also picks up the pieces that they drop.

Mom Hornby noticed a stick that was too close to one of the eaglets today (May 15), and might have caused an injury, so she walked over and moved the stick out of the way, just as our Mom or Dad might have done to protect us.   :eclove

To all who can help...

Thanks so much.  It has been awhile since we have been to the forum.  The kids do watch Alexandra and David every day.

Some questions directly from the 3rd graders:

1.  When mom or dad flies into the nest very fast do they know how not to step on their babies? From LB

2.  When an eagle is in the area - how long are they on watch?  From CB

3.  Do the eagles attack live animals and bring them in - other than fish?  AT

4.  When eagles are both on the nest and on alert...why doesn't mom or dad cover the eaglets?  TB

5.  How many eaglets is possible for Ma Hornby in her lifetime?  How many has she had so far?  ES & GH

6.  How far can they see?  LB

7.  Which tree is the babysitting tree?  How did it get its name?  Mrs. Puerzer

Whenever you can get to us with answers that would be great.  The class was so excited about asking questions today.

Happy Memorial Day!

Ms Puerzer's class, you have asked some great questions!

But I will answer Ms Puerzer's question first.

There is a reference topic in the forum where a labeled picture shows some of the trees we talk about. The babysitting tree is out of the cam view but an arrow points to where it is located in relationship to the nest. Here is the link to that map

http://www.ournaturezone.com/index.php?topic=227.msg8770#msg8770


(the eye branch was trimmed away last fall when the tree climbers went up to clean the cameras and trim some branches)

Next is a link to a photo that boonibarb (who lives on Hornby Island) took showing how far it is from the nest. The babysitting tree is the one on the far left of the photo. You can see the nest on the far right.


http://www.ournaturezone.com/index.php?topic=529.msg56333#msg56333


copyright boonibarb 2011

The parents can sit in the babysitting tree as the eaglets get older and larger and "babysit" from nearby. It gives the eaglets more room to excerise their wings and move about the nest as they grow.

I will leave the other questions for AJL. She is "our" teacher about the eagles.

Hello Mrs. Puerzer's Class!  :heart

LB asked,
"When mom or dad flies into the nest very fast do they know how not to step on their babies?"


Mom and Dad know how not to step on the eaglets because they use their excellent eyes, their ability to judge distance, and their experience in everything they do.
They can see the nest from a great distance, so they know where the eaglets are before landing!

CB asked,
"When an eagle is in the area - how long are they on watch?"

They remain 'on watch' until they feel the threat has passed, and that can be minutes, hours or most of the day!  :eceek

AT asked,
"Do the eagles attack live animals and bring them in - other than fish?"

Yes AT, eagles will hunt living animals, in addition to scavenging dead ones. We haven't seen the Hornby eagles bring live animals to the nest, thank goodness!

TB asked,
"When eagles are both on the nest and on alert...why doesn't mom or dad cover the eaglets?"

When the eaglets are small, a parent will cover them or hunker over them when there is a threat near the nest, but as they grow it becomes nearly impossible to keep them covered, so they will stand near them. Usually one parent guards the eaglet while the other perches nearby, ready to give chase.

ES and GH asked,
"How many eaglets is possible for Ma Hornby in her lifetime?  How many has she had so far?"
 
This is a good question!  :puzzled2

We hope that Mom Hornby will have a longer life, but most eagles live around thirty years.
A female usually starts breeding at five or six years of age.
A thirty year-old eagle who had her first eggs at five years of age, could lay eggs for
30 - 5 =   :question  years!

Mom Hornby lays only two eggs.
By the age of 30, she could have had
25 x 2 =  :question eggs.

However, eagle moms don't lay eggs every single year, and not all eggs hatch.
Mom Hornby did not lay eggs in 2008, and not all the eggs she laid over the years hatched.
We think she has had 21 eaglets, and Alexandra and David make 21+ 2 =  23!

LB asked,"How far can they see?"
Really far!  :mhihi  If an eagle is perched in a tree and turns its head to look around, he or she can see about three miles in any direction.  And an eagle can spot prey from a mile!

Thanks for the great questions, Ms. Puerzer's little scientists!  :eclove

Ms. Peurzer, Wisconsin is home to the world's best Bald eagle rehabilitator, Marge Gibson.  Her centre, REGI (Raptor Education Group Inc.) is located in Antigo.
REGI has an education program and I believe they still do some classroom presentations, as well as some public releases of rehabilitated Bald eagles.
http://www.raptoreducationgroup.org/Educational_Program_Descriptions.cfm

REGI also has a blog, where patients and issues are discussed, and photos shown. It might be a great teaching tool for you.  http://raptoreducationgroup.blogspot.com/

Thank you for answering all the questions from my class.  They were so excited.

Thursday is the kids last day but will keep in touch over the summer.  Are the kids able to contact you with questions during the summer using their initials only?

Here are more from my 3rd graders:

1.  How old are the eaglets when mom stops sitting on them?  HV

2.  What is the longest time mum has been away from the nest with the eaglets alone?  JN

3.  When will mom & dad leave the nest and where do they go after the eaglets leave the nest?  CB

4.  How many more days will it be until they fledge?  ES

5.  Do the eaglets go to the same place as mom & dad?  Mrs. P.
6.  Where do they go?

7. Do the eaglets eat more in the morning, at noon, or at night?  BJ

8.  How long do the mom & dad feed the eaglets?  EA

9.  How many days will it take for them to learn how to fly?  AK

10.  How about the sneezing...has their been concern for their health or is it more the grass, etc.?  Mrs. P

11.  How old will they be when they make their own nest?  LC

12.  Do they come back to Hornby Island with a mate and do they nest there?  Mrs. P.   Have the eaglets ever been banded?  What are your thoughts?

13. How wide is the wing span of the eaglets?  DO

14.  A few days one of my students heard the eaglets make a very strange sound - does that have meaning for something different or is all because they are hungry?  GH

Again, I thank you for all of your help.  I look forward to keeping in contact and I am hoping so much that both fly off successfully.  Still feeling so bad about last summers events.

Hi JP,

Yes, if their parents register on the forum, using their own screen names, they can post their child's questions on your class thread and just put the student's initials with the question.

Our Nature Zone Forum link:

http://www.ournaturezone.com/index.php  

We know you don't have much time left, but maybe you can give the students the link to the forum before they leave on Thursday, with instructions about where to post their questions.

Have a nice last two days with the kids!   :thumbup:

Hello everyone in Mrs. R's class!

1.  How old are the eaglets when mom stops sitting on them?  HV
HV, Mom and Dad stopped brooding the eaglets a few weeks ago, when they became too large to fit beneath them.  :eclol  The eaglets were able to tuck their heads beneath their parents when it was raining or they felt cool but now they becoming too large for that too!  The eaglets' head feathers are in now and their body feathers are growing rapidly, so they no longer need as much protection from weather.

2.  What is the longest time mum has been away from the nest with the eaglets alone?  JN
JN, while it may look like the parents are away, almost always, one parent is either on the wide angle cam box, the top of the trunk or on the babysitting tree right next to the nest. Now that the eaglets are large, walking and flapping their wings a bit there isn't enough room on the nest for a parent and it will look like they are alone for long periods - but Mom or Dad will be nearby.

3.  When will mom & dad leave the nest and where do they go after the eaglets leave the nest?  CB

CB, when the eaglets fledge the family will stay in the territory until the eaglets are flying strongly. Later in August, they will all go to the salmon runs. We don't know exactly where the Hornby family goes but there are salmon rivers nearby on Vancouver Island.

4.  How many more days will it be until they fledge?  ES


ES, the Hornby eaglets typically fledge at around twelve weeks of age, give or take a few days. This year, that might be sometime around July 22.

5.  Do the eaglets go to the same place as mom & dad?  Mrs. P.
Mrs. P, in 2009 our eaglet Hope left the island with Dad, so would have gone where he went. Mom stayed for a little while longer but it is very possible they go to the same place.

6.  Where do they go?
There are salmon rivers, like Big Qualicum and Goldstream, on Vancouver Island and all the way north to Alaska! We don't know exactly where they go, because they're not banded.

7. Do the eaglets eat more in the morning, at noon, or at night?  BJ
BJ, they eat whenever they can.  :eclol  How much they eat depends on fishing that day. If there isn't much fish first thing in the morning, they might eat a huge meal when the first fish comes in later. Mom and Dad usually try to fill them up before bed, too.

8.  How long do the mom & dad feed the eaglets?  EA
EA, Mom and Dad will continue to provide food to the eaglets even after they fledge, until such a time that they're doing well themselves. Even when the eaglets are feeding themselves on the nest, Mom will continue to beak feed them right until fledge.

9.  How many days will it take for them to learn how to fly?  AK
AK, they fly when they depart the nest, but their first flights are not too long. Each time they try, their muscle strength improves so in no time, they are zipping around as though they were born to fly.  :puzzled2

10.  How about the sneezing...has their been concern for their health or is it more the grass, etc.?  Mrs. P

Mrs. P, we don't know. Observations team members are noting the sneezes and Maj at Mountainaire Avian Rescue Society (MARS, the nearest wildlife rehab) is aware.

11.  How old will they be when they make their own nest?  LC
LC, they're usually 5 1/2 to 6 years when they are ready to nest - but some eagles as young as 4 1/2 years of age have been observed nesting.

12.  Do they come back to Hornby Island with a mate and do they nest there?  Mrs. P.   Have the eaglets ever been banded?  What are your thoughts?
Mrs.P, telemetry studies are showing that birds do return to natal areas to breed. I know of at least some though, who were recruited as mates by widows or widowers in other places.

Hornby eaglets have not been banded. Bands don't yield as much information as you might think - single point sightings sometimes, and some band returns (when birds are found dead, or admitted to rehab) don't provide as much information as do telemetry, and wing markers.


13. How wide is the wing span of the eaglets?  DO
DO, we can't know without measuring but right now their spans appear to be less than the nest cup itself, which is around 3 1/2 or 4 feet perhaps. Over the course of their nestling period, their wings will grow nearly an inch/day! 

14.  A few days one of my students heard the eaglets make a very strange sound - does that have meaning for something different or is all because they are hungry?  GH

The eaglets' vocalizations mean many things to their parents. Some (e.g. the 'tea kettle whistles') signal desire for food or comfort. Others may be in response to parents flying in or sitting nearby (Hello, I see you!). Others signal contentment (churbles) or annoyance (chirp chirp get off me!).

Mrs. P's 3rd grade students, we hope you have a wonderful summer holiday and that you will wave hello to all the eagles you see! Now you know who they are, how they live, and what they need to be well. Take took care of them and their habitats so that someday, you will be able to introduce your own children to these splendid birds.
