With 50-60 bald eagles now living across the eight Channel Islands, no island foxes are known to have been killed by golden eagles for several years. Bald eagles definitely make a difference in the ecosystem for island foxes. But what benefit do island foxes provide bald eagles?
Across the Channel Islands bald eagles are hatching out their 2018 chicks. Channel Island National Park reported that there are 13 active bald eagle nests across the islands this year and at least 22 known eggs.

Tonight, close observers saw some unexpected visitors to the bald eagle nest. Along with fish, the parent bald eagles have brought scavenged seal placenta back to the nest to feed their chicks. But with the darkness, something else stole up into the nest to eat the placenta bits. Circled in green, do you see the surprise scavengers? island deer mice.

Island foxes play an important role in controlling island deer mouse populations.
Other bald eagle parents on the islands are sleeping soundly tonight, but the bald eagle with the messy nest is wide awake in the rain. It has two jobs tonight: keeping three eaglets warm and dry, and keeping the deer mice at bay. It will be a long night for this bald eagle, it needs an island fox.
