    A young bald eagle, about three and half months old, on a street light. It only takes bald eagle chicks about 12 weeks from hatching to grow to adult size, and they can start flying. However, it takes another four years for them to mature. The head and tail feather will gradually change to white. Statistically, only about 15% of the eaglets manage to survive the full four years to enter adulthood. The fatality rate in the first year alone is about 50%.

  4. A naturalist noted in a talk on our recent Alaska cruise that "Young Bald Eagles are stupid and frequently die doing dumb things that adult eagles would never do." He then went on to note a few examples he had witnessed in the wild. (Reminds me of 15 year old human males, but without the same mortality rate...)

    I am curious to know what those examples are. Two years ago from that same nest, we had two eaglets. One was electrocuted on a power pole in the area. :eek: The other is, surprisingly, still in the general area and is establishing her own territory. Typically young eagles travel a couple of miles and establish they own area pretty far away from their birth nest.
     
  6. Just yesterday I ran across one of those click-bait series on the dumbest birds--

  8. Sorry, but I don't remember the details. I only remember thinking how much juvenile bald eagles sound like male human teenagers.
