High atop the mountain peaks, the eagle possesses a wondrous ability to locate its prey from vast distances. It deliberately chooses these towering heights as a dwelling place to survey the landscape and hunt for food [מצודת דוד, ביאור שטיינזלץ]. The eagle's hunt is much like a scouting mission. Just as spies carefully survey a territory, the majestic bird scouts the ground below [רלב״ג, מלבי״ם, אבן עזרא, אלשיך]. Searching from such an immense altitude is compared to a person digging deeply into the earth in pursuit of a hidden treasure [אבן עזרא]. Once the prey is found, the eagle either consumes the meal itself or carries it back to the young chicks waiting in the nest [רלב״ג, ביאור שטיינזלץ].
In the natural world, living at such extreme heights might seem like a severe disadvantage. An ordinary eye cannot detect food on the ground from that distance, which would normally leave the bird to starve. Yet, God steps in through His providence, granting the eagle extraordinarily powerful vision. Because God provides this unique sight, the eagle can look from afar and miss absolutely nothing, spotting its prey even if it is hidden deep within the earth [מלבי״ם, אלשיך].
Taking a completely different, allegorical approach, [רש״י] applies this imagery to Aaron the High Priest. In this view, the eagle's search for food represents Aaron standing in his elevated, honorable position, praying for the yearly livelihood of the Israelites. Tragically, despite his great honor, Aaron was forced to watch the death of his two young chicks, his sons Nadab and Abihu. They died to sanctify the name of God, and their sudden passing cast a heavy shadow of fear and awe over the entire nation.
