This is in reference to young eagles that are taken to a hack tower in order to be released in a different location than their hatching location. The “hacking” program is predicated on the well-known notion of “fidelity” in avian biologymore precisely, fidelity to birthplace in this instance. When it comes to hacking, we use this theory to predict that young eagles raised in hacking towers will perceive it as their nest site and will orient themselves toward it after they have flown.
Typically, when we think of migration, we picture birds flying from north to south, depending on the season. That’s true for a lot of birds, including a lot of prey birds. However, for bald eagles, it’s not that easy! A number of factors come into play, including the bird’s age, location, and access to food.
Since eagles fly during the day, we think that they use well-known landmarks to get to the general area and then use more specialized and familiar cues to locate their specific lake and nest tree. First, cues like vast mountain ranges, bodies of water, or the coastline could be used.
Two 13-week-old eaglets were released by the AEF from our hack tower on Tennessee’s Douglas Lake on August 2, 2013. Destiny, these eaglets Sadly, after a few weeks, the tracking devices stopped working, making it impossible for us to follow them. But in a matter of days, Thunderbird reached Lake Huron, which is near the Canadian border, and Destiny traveled to Ohio. Since then, Destiny has been spotted multiple times; her patagial wing tag, L3, allows us to identify her. According to a rumored sitting on August 30, 2015, Destiny was still in good health. We learned in 2020 that Destiny is currently nesting in Tennessee.
Eagles do not fast in order to lose weight; they will eat normally prior to migration. If food is easily accessible, they might even have a tendency to eat more in order to fill up. We have also seen migratory eagles reloading on food while traveling. For example, a migrating bird may pause its migration for a day in order to gorge itself on the available food if it finds a deer carcass. PN.
