What to look for
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.
Three young successfully fledged in 2014!
Assisted in banding three other nests along Wolf River near New London, WI with fledging successes at all with production of 3, 3, and 2 per nest, Great YEAR!!
This pair of ospreys have been searching for appropriately high platforms for several years and frequented several athletic field light posts which brought out some ire from managers and city officials. Through a generous donation from ATC for two 70 foot power poles, Wisconsin State Patrol for escorting the transportation of these from from Shawano area to Waupaca, and Wisconsin Public Service for the attachment of the platforms and erection of the poles within the Lakeman Baseball Field and Haberkorn Athletic Fields. Shortly after settling this 3 year decision by the school district officials and the City of Waupaca officials, the ospreys made the decision to make their nest at the Ball Park Sports Bar baseball field on shorter poles but a more isolated area with adequate water and local fish populations. With these available platforms and a new one to support the present nest at the Ball Park Sports Bar, additional osprey recruits will have more choices in the future.
