What to look for

Adult Arrival

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.

Incubation Initiation

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.

Clutch Hatching

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.

Nestling Count

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

Fledgling Count

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.

Nest Failure

Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.

Again today, we are not seeing any evidence of rebuilding. This is an active grain mill, so they may have been "discouraged" in some way.

04/09/2022 by francie

We are not seeing any rebuilding. There are so many areas this pair could have chosen to rebuild, since they had to rebuild in a different spot last year.

03/25/2022 by francie

Another nest that needs rebuilding, but both osprey were in the area of last seasons nest today.

08/11/2021 by francie

It's hard to say if there were any fledglings in this nest. There was an osprey on the side of the nest for quite some time, after the incubation period. But as it is so high, we never did see if there was more than one at the nest any given time.

06/06/2021 by francie

This is the first time that we could actually see an osprey sitting up higher in the nest, off to the side. Hoping for a positive nest this year!

05/28/2021 by francie

We could see one osprey sitting on the mill near the nest today and what may have been the others' head in the nest. Again, this nest is very high on the mill.

04/08/2021 by francie

The pair appears to be staying at this nest, after some rebuilding, but it is so high up on the grain mill that we can't see what's going on. We have seen them on it, near it, and around it though.

03/31/2021 by francie

This pair had a nest on an old pole, no support whatsoever, last season. Unfortunately, they lost it to a high wind and tried, unsuccessfully, at this new location on the grain mill. We just noticed that they are rebuilding this season, on the grain mill.
