This is a new nest in 2020. It is on the south side of the water tower in the Spring Lake Public Works yard. The nest faces the North Branch of Wreck Pond. It is occupied as of July 2, 2020, but difficult to determine the number of chicks due to the height of the nest. However, an adult was observed overseeing the nest.
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.
This nest was removed by communications workers on Jan. 31, 2022. On March 22, a pair of fish crows began building a nest on the site. On April 2, the ospreys arrived, drove off the fish crows, and began rebuilding the nest. The nest is not as large as the previous one but seems to be more protected. At just before 2 PM this afternoon, one of the osprey arrived at the nest with a fish. The other osprey promptly dropped into the nest. Unsure if there are eggs yet. The pair have been extremely active the past week.
This nest has been active throughout May into early June. However, what appear to be Verizon workmen have been seen on weekends using a bucket lift to work on the cells on the tower. I observed the lift raised in early June but no workmen were present. On June 19, however, 3 workmen were present and working within feet of the osprey nest. See photos.
At 8 AM, Sunday, June 20, I was able to confirm that the nest is still occupied. I saw an adult osprey bring a fish to the nest and observed movement within. A series of photos show an osprey head bobbing in and out of sight inside the nest. See photo.
This nest is new in 2020. Parents may be young raised in the nearby Warren Avenue nest site. Parents are active around this nest, although due to its height, it is difficult to tell how many are occupying it.
