For years, I have been collecting material for a Bald Eagle Glossary (dating back to my time as head mod at the Decorah eagles cam), but it took a back seat to other things. I have finally had time to work on it in earnest, and a few weeks ago I made a preliminary version of it live on my website. It is a work in progress, and probably will be for as long as I am able to maintain this website.
Some entries are simple defintions. Others add details relevant specifically to Bald Eagles. In many entries I have added details that explain things that cam observers have seen occur on nests, or that reveal aspects of Bald Eagle biology or behavior that only biologists know or think ir wonder about. One of my favorite things, etymology (linguistic origins of words), is included in some of the entries. For example, under “photoperiod,” Greek phos = light.
I add new terms regularly and update entries as I learn more. I welcome suggestions (and corrections from those who know more than I do), including requests for new entries.
