Bald Eagle


Haliaeetus leucocephalus

Status: The Interior Department removed the bald eagle from the endangered species list on June 28, 2007.  The bald eagle will still be protected by the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act.

By Melanie Lintner




Physical Description:
The bald eagle is actually not bald, but has white feathers on its head.  The newly hatched bald eaglets are light grey and turn dark brown before they leave the nests at 12 weeks. During their third and fourth years, bald eagles have mottled brown and white feathers under their wings and on their head, tail and breast.  The distinctive white head and tail feathers don't appear until the bald eagle is 4 to 5 years old.  That is also when the beak and eyes turn yellow.  The beak and eyes are brown prior to this maturity.  The bald eagle generally has a height of 29 to 42 inches and a wing span of 6 to 8 feet.  The male weighs 8-9 pounds, while the female weighs 10-14 pounds.

Habitat:
The bald eagle lives and nests near coastlines, wet prairies, lakes, rivers, and coastal pine lands in North America from Alaska and Canada to Florida and Baja, California.  They choose an area with tall trees for nesting and roosting and plenty of fish to eat.  Bald eagles are found in every state except Hawaii.

Threats to Survival:
The bald eagle's threats to survival are both natural and human.  The bald eagle is subject to poisoning by pesticides and also secondary poisoning.  They are also subject to electrocution from flying into electrical wires.  Hunting and destruction of their habitat also threatens the survival of the bald eagle.  The adult bald eagle has no natural predators, but there is a high mortality rate for the eggs and young eaglets.

Daily Reflections                      

Personal Teaching Connection

Monday
We started the day with a reading from Lennie.  She read a poem about the prairie.  She found it in a book that she had purchased from the bookstore in the Portland Museum of Art.  Next, we went through a mapping activity of the Fading Footprints web site.   We then moved on to our workshop on the summit species page model.  We started creating our own pages with information about the bird that we were studying.  I am studying the bald eagle.

On the way back from lunch, Lennie and I walked along the path.  We enjoyed the wonderful view.  I took some pictures along the way.

After lunch, David Sparks showed us several animals that he had with him.  He had some dead brown bats.  All of the other animals were alive.  He had a flying squirrel, a box turtle, a chifallow deernchilla, a fallow deer, a skunk, an owl, and a boa constrictor.  I was surprised at how soft the chinchilla fur was.  Some were brave and allowed David to put the boa around their neck.  I was not one of them. 

Our next activity was our art lesson.  Ellen showed us the method to use to reproduce a picture of our birds.  We made a grid on the original picture and on the blank piece of paper.  We used strips of paper to measure the points where the pictures crossed lines on the grid.  We had to draw free-hand.  The next step was to put our picture face down on a light table.  We traced around our drawing, but the tracing had to be larger than our drawing.  We then used a pencil to shade in on the back side of the drawing, creating our own carbon paper.  We were then to tape our drawing to a piece of water color paper and use a pen to trace over our drawing.  It would be transferred to the paper below because of the carbon paper that we had created.  I was not able to do the last step because Ellen thought that it would be best to enlarge my drawing using a copy machine.  That way my drawing would cover more of the 8 1/2 X 11 paper.

I ended up having an hour and 45 minutes of free time.  It was cold and rainy outside, so I decided not to go for a walk.  Lennie and I ended up discussing how much students have changed over the years. 

After dinner, we met downstairs to discuss sharing our photos using Picasa.  We then had time to work on our web pages.  It has been a busy, but enjoyable day.

Product Design
My personal connection is as to how I can work with the teachers to help the students to create their own pages.  I will encourage the 7-12 teachers to have students create pages based on their expedition for the year.  I will also work with the elementary teachers who are willing to tackle this type of project.
Tuesday
We started the morning with a reading from Tom from the preface of Sibley's book on bird species.  We went to the  Goose Rocks beach and met with Joy and Jordan with the U. S. Fish & Wildlife.  They discussed the nesting of the piping plover and least tern nestileast tern nestng.  We recorded activity of the piping plover.  We came back to the McKernan Center for lunch. 

After lunch, we read an article, "Anatomy of an Expedition", that was written by David Grant.  We discussed the ELOB framework.  Next, we had our first watercolor lesson from Ellen.  It certainly wasn't as easy as she made it look.

Lennie and I went for a walk, in hopes of seeing the museum, but it was closed for the day.  We enjoyed the walk anyway.  We had Thai for supper.  That was a new experience for me.  It wasn't bad at all.

After supper, we each discussed how we were feeling about our project.  We then worked on our web pages.  Most people worked until 9:45, but some stayed after that.

Anatomy of an Expedition
I feel like I have a better grasp on the total process.  I feel more comfortable about what I will be able to contribute to my group's efforts for our expedition.
Wednesday
We got up early this morning for a 6:30 breakfast.  After breakfast, we went to Scarborough Marsh for a canoe ride.  We saw the Common Tern, Double-crested Cormorant, Glossy Ibis, Great Blue Heron, Great Egret, Herring Gull,  Marsh Wren, Red-winged Blackbird, Semipalmated Sandpiper, Snowy Egret, Tree Swallow, Willet.  I canoed with Tim and Ashli. 

We worked on iMovie when we returned from the marsh.  I enjoyed the editing aspect of iMovie, once I got over the fear of messing it up.

We ate lunch and then had another art lesson.  We painted the background of our pictures.  I wasn't exactly pleased with mine.  I'm really nervous about making my bald eagle look 3-dimensional.

Our next activity was to finalize our species page.  We are also going through a check point and dropping our files onto the server.
Fieldwork and Community
I plan to relate my experiences of the week to Steve Goodlet.  He would enjoy this expedition immensely.  I can see how this can be adapted to other disciplines and to our community.
Thursday
We awoke to a beautiful day in Maine.  Our morning reading was by David and from the ELOB book.  Ellen followed that with a quote.  This morning we focused on structural, documentary, and topic pages.  We divided into teams for the topic pages.  I am working with Courtney and Nicole on the technology topic page.  We came up with the main ideas for the page before lunch.

We had lunch at the cafeteria today.  We ate outside since it  was a beautiful day.  We headed back for our art session.  I was really stressed about painting the bald eagle, but surprised myself.  It took me several hours to complete it, but I finally did.  Courtney typed the information for the technology page while Nicole and I finished our paintings.

At supper we celebrated Leah's birthday.  The staff brought  out a cheesecake with candles on it.  The cheesecake was delicious. 

Courtney, Nicole and I met to review our technology page.  We made some revisions, but feel good about the overall content of the page. 

Kira, Courtney and I decided that it was time for a walk.  We walked down the path to the entrance of the beach that is by the cafeteria.  We took off our shoes and walked along the beach.  The water was cold, so we stayed in the sand.  We walked as far as we could, and then exited the beach.  We walked a little farther until the path ended.  We were up on a hill with a terrific view of the other lighthouse.

Most of the groups are stressed about their topic pages.  We feel like we are finished with the technology page.  I'm getting nervous now, thinking that maybe we haven't included everything that we might need.

Differentiation and Assessment
It is important to assess the students on several different activities as the expedition is progressing.  It is imperative to have things planned for the students who finish early, and offer alternative instruction and assistance for those students who need help to complete the product.
Friday
We woke up to another beautiful day in Maine.  After breakfast we worked on our topic pages.  We made some revisions to the technology pages.  The entire group critiqued one another's topic page.  We then went back to revising the pages using the suggestions from the others.  Nicole wanted to complete the page, so she skipped lunch. 

We completed most of the page before we started our technology piece of the expedition.  David discussed image compression and the embedding of videos.  I have never embedded video before.  I am looking forward to trying this. 

We then discussed the other pages that needed to be designed to complete the product.  Some of us volunteered to do those pages.  Nicole and I volunteered to do the crew page.  She had an idea of what she wanted to do for it.  We plan to put in individual pictures and the group shot.  Ashli took the individual pictures for us.  David imported and resized them for us.  We were getting down to crunch time on completing the crew page, and we still needed to type in email addresses and schools.  Tom volunteered to type the names below the pictures and type in email addresses.

Technology
I hope to have more time this year to devote to the individual teachers.  Some of them need a great deal of encouragement to step out of their comfort zone and integrate more technology into their classroom.  I know that Lennie is now ready to do this.  She has accomplished so much this week.

I want to make the time to incorporate some of the technologies of the summit that I have never used before.  I have used a video camera before, but I had never filmed for a documentary.  I enjoyed editing the video clips in iMovie.   I had never used Picasa before, but I now have it installed on my personal laptop.
