Weighing (their weights were 2.5 pounds, 2.0 and 1.75 pounds). They are a lot larger on the ground than how they appear in the nest!

Returning home to the nest

The one on the right fell asleep right away -- the middle one dropped off to sleep right after this picture.

I am sure there will be a lot more pictures on their webcam site later. Right now I need to log off and get ready for house guests on Friday.

I had to come back and tell you that one of the eaglets has already removed a band and played with it. The biologists have been notified.

Thanks guys!!!!
I wasn't here, as I sorta knew I wouldn't - I much appreciate the pics and the story!
Best part must be the band that came off
I was thinking to myself already earlier, that they do band the awfully early - compared to the WTEs last year....

I just missed seeing this by 15 minutes!

Update by Norfolk Botanical Garden at 12:24 PM:

Nate from Nuckols tree service has returned and is removing the loose band from the nest and the other band from the leg of the middle eaglet. The youngest eaglet did not receive a band earlier – it’s legs were too small. (They should have asked Caysa before going up! )

chick reaction is normal - not upset

an adult is circling overhead monitoring

He is just going to slip off the band.

Both bands had come off so Nate just collected them and is descending.

CCB will apply the bands on the younger 2 chicks when they fit one of the eaglets for a satellite

The removal of the bands was a precaution and posed no serious hazard for the chicks

Both bands for the middle eaglet (originally banded ND) had fallen off and they were retrieved from the nest

Measurements were inconclusive to determine whether male or female.

Broods of 3 chicks are sometimes unpredictable in growth rate and the legs of 2 younger eaglets were a little smaller than anticipated. This is due in part to a slightly slower growth rate than predicted. (That is probably because the oldest one would not let the other two have any of the food when they were first born! ) It is also possible that they are undersized because they are males, but CCB could not be sure at this time

They also reported that the nest bowl is 36 inches inside (the whole outer nest is 64 inches) and it is an average of 32 inches deep.

In the late afternoon sun, the pine trees look like they have golden flowers



The end of an exciting day for the eaglets




Here is a link to see photographs taken on the ground during the banding:

Yes, I know they were close... but how long did it take before they returned to the nest and started feeding the poor babies again??

Caysa, I stopped watching when the eaglets where brought back to the nest. However, someone on their message board indicated that the chicks were fed after they woke up from their nap after banding.

I did find an explanation of why the banding was attempted so early. This is taken from a post by the director of the Conservation group that was in charge of the banding:

The chicks today were 21 days old (1,303 grams), 20 days old (980 grams), and 18 days old (796 grams). This is a typical stagger for a 3-chick brood. Three chicks are the maximum brood size for bald eagles and due to the time difference in hatching the first-hatched chick has quite a head start that it maintains often into the fifth or sixth week. Adults typically are unable to provide the same resources per chick for all three chicks that they can for one or two chick broods and the deficit is mostly borne by the younger chicks resulting in slower growth rates.

Over the past decade we have worked with many broods on the tributaries of the lower Chesapeake Bay. These are some of the most productive waters for eagles in North America. They support some of the highest breeding densities on the continent, the largest average brood sizes, and the fastest growth rates. We have measured many eaglets 15-20 days old and none have been less than 1,000 grams. Most chicks that are 20 days old are more than 2,000 grams and are of perfect banding size. Between 15 and 40 days of age these chicks have an average daily weight gain of 150 grams. The average weight for 15-day old chicks has been 1,350 grams. This is higher than the 21-day old chick today and nearly twice the weight of the youngest chick. Note that the chicks today were perfectly healthy. They are simply growing at a slower rate than those of the lower Chesapeake.

We have no growth data from the outer coastal areas including the Delmarva Peninsula and Lower Tidewater. The difference between this brood and the broods of the lower tributaries lead me to misjudge the early banding date but also invites new research questions. We need more information on the pairs breeding on the outer coastal fringe for comparison. We will measure these chicks again when we return later in the spring to deploy a transmitter. These chicks and others to follow will add to our growing understanding of the ecology of this magnificent species in the hope that it will improve their management in the years to come.

Feeding is a whole lot calmer now. Gone are the rough and tumble days of pushing and pecking at each other.



If anyone is interested, this was posted this morning in the blog to the right of the video picture:

I have had numerous requests to hold one of my NBG bald eagle classes online for those unable to travel to Norfolk. I will do so on Monday April 12 from noon to 1:00pm EDT in the WVEC Moderated Blog. (The time would be 19:00 Estonian Time)

I encourage folks to read the list of terms I posted on the eaglenest.blogs.wm.edu site on April 5. These are terms I used in my NBG class on April 3. I will focus on eagle basics and what you have been seeing and will see in the nest in the next few weeks.
