Nest is on the south side of I-84 on very high utility pole just across from the westbound (only) rest stop a mile 65, also called Koberg Beach. You can see the nest as you drive by at 65 mph heading east or west on I-84. But better viewing (ha ha) is either from the beach on the Columbia River (you can part for free at rest stop) or from above at Mark Hatfield Tunnel Trail parking area (day fee) that is on the east side of Hood River. Take foot path a hundred yards due north from the parking area to small overlook.
Look for 2 adults on the nest. The adult pair will show pair bonding behaviors such as vocalizations, aerial sky dances, and the male feeding the female fish. You may see the pair copulating, which typically begins 14 days before laying eggs.
Females will lay 1 - 4 eggs at a rate of one egg every 1 - 2 days. After laying, incubation starts. Look for adults taking turns sitting low in the nest incubating eggs. The incubation period can last 35 - 43 days.
Chicks hatch ~39 days after incubation begins. Look for adults bringing food to the nest and making "head bows" into the center. Chicks typically can't be seen until they are 2 - 3 weeks old, so feeding behavior is the only way to know chicks are there.
Around 4 weeks after hatching, look for the heads of chicks to show over the rim of the nest, particularly when adults bring food to the nest. Other times they lie flat and are harder to see. Count the number of chicks in the nest before they learn to fly
Chicks begin flying around 7 - 8 weeks old, and are still fed by the adults. Count the number of chicks who have successfully fledged the nest and are observed flying.
Chick Last Observed
4 - 10 weeks after fledging, chicks begin leaving the nest area to migrate south, once they have learned to fly and feed themselves. Record the date that the last chick left the nest.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.
They're back from adventures south! Three osprey seen today 3-30-18 soaring above this nest (#7009) and an hour later one osprey on the nest doing nestorations. I watch this nest almost daily and I believe they have just returned in that past day or two. I don't know if I am the only one here in the Columbia Gorge that is super thrilled to have these dear "friends" return for the season. Joyful. Grateful.
I have watched this nest for several years on a daily basis, although often that is driving by at 65 mph :) Last year the adult pair fledged at least one chick and most likely two. Adults migrated south in early fall. As of mid-March only one sighting of an adult on nest and can not confirm it was an osprey, because only got a quick look and BEs hang out in that area as well. Will report back when I know more.
