Herrings vs. Eagles – Eagles Win and the Photographer Did Too

Arguably herring are the base of the entire food chain in Southeast Alaska. They provide food for whales, salmon, seals, sealions, birds, and halibut with their bodies and with their eggs. For centuries humans have relied on the abundance of herring to provide for their families in the spring.¬† In Hoonah, Alaska the return of herring marks a change in the a season and a bounty of fresh eggs brings a welcome smile to the elders and community members that receive them. However, in recent years the herring run has not bee large in Hoonah although anecdotally (and a bit facetiously) you could “walk across their backs to Pitt Island” only a couple decades ago. Ocean changes, over fishing, and habitat loss have all contributed to decreasing herring returns and fewer spawning fish in recent years. This knowledge made me feel particularly fortunate to get to see herring spawning in Hoonah and watch the harshness of nature unfold before my eyes as Bald Eagle scooped the silvery fish from the ocean.

Spawning herring rely on seaweed and objects in the water to glue their eggs to. Spawning females mix with males and each emit eggs and roe into the water. A sure sign that herring are spawning is a milky, blue water that combines the colors of the ocean and the white of the roe. The need to stick their eggs to seaweed brings the herring close to shore and thus susceptible to predation. As I walked near Cannery Point in Hoonah, Alaska over 30 eagles (a mix of juveniles and adults) lined up on the beach. The color of the water  and brilliant flashes of silver near the shore left little doubt on what they were feeding on!Bald Eagle, Hoonah, Alaska, Herring, Feeding, Southeast Alaska

Herring egg harvesters use branches of Hemlock to capture herring eggs. They lay the branches in the water where herring are spawning and then collect the branches which are (hopefully) laden with eggs.

Trial and Error

One of the first things I noticed was the juvenile eagles were watching the adults very closely. They knew they had a lot to learn, and there was no doubt after several minutes of watching that the adults were much more efficient at catching the herring. Most of the adults would launch from the beach, strafe their talons on the water’s surface and come up with one or two herring. Some eagles opted for a higher vantage point and flew in from the trees on the embankment. Another strategy was to simply stand on a rock or in the water and hope to catch one in without flapping a wing. All of these strategies produced herring for the eagles and the juveniles mimicked them perfectly.

Meals on the Wing

Even though there was an abundance of herring one strategy of some eagles was to steal from those that were successful. The fierce competition from other birds forced successful eagles to eat very quickly and on the wing. Almost all of the eagles would transfer the herring to their beaks and then orient the fish head first before finally swallowing it hole. This occurred in just a few seconds to remove any chance of pestering, marauding eagles from stealing their catch. I did get to watch once instance where an eagle successfully scooped two herring at once, but did not eat them on the wing. Immediately three other eagles (2 adults and a juvenile) put up chase resulting in the eagle dropping one herring to get rid of the pestilence following it.

Repetition, Repetition, Repetition

It was incredible to watch the eagles feed on the herring and learn from their behaviors, but as a photographer I was grateful for the frequent and repeated attempts by the eagles to capture herring. I had the opportunity to tinker with camera settings and capture a lot of shots that are high quality and showcase the slice of foodweb that I was only a spectator to.

This is my favorite shot from the day. I slowed my shutter speed down and then tracked the eagle as it flew to a perch. The face and claws remained tack sharp and I achieved blur in the wings and the background.

This shot is a close second! I cannot believe the symmetry that these two eagles have as they flew away, or that they both caught herring!
