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.
There are many nests and all the spotted ospreys appear to be female including the nest I was accounting for. This adult female is consistently perched 100m away from the nest- if it is her nest. I assume it is since this is the closest osprey to the nest
Today I spotted (2) juvenile ospreys sitting in the nest. One sitting up more towards the edge of the nest, one sitting low in the center. Male osprey was spotted perched on (usu) tree branch across skate park.
First time visiting this nest. Saw a male perched up in nest. Male flew to a nearby tree where we continued to perch for several minutes. There was a group of skateboarders making a decent amount of noise (just below nest)
Today was the first time that I found the nest. There were about a dozen skateboarders around the nest. The nest is quite low to the ground. There was a male osprey occupying the nest. The osprey made eye contact with us and flew away into a nearby tree.
