In SE Alaska every spring spawning herring set in motion a cascade of feeding within the animal kingdom that has been repeating for more than 10000 years. This wildlife spectacle includes the return of humpback whales from winter breeding grounds as well as an aggregation of marine mammals, eagles, gulls and sea ducks all sharing in the bounty. #alaska #humpbackwhale #wildlifephotography #orcas #killerwhales #herringspawn #sealaska #bubblenetting #baldeagle #sitka #northernsong
