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.
Male on nearby light pole, female perched in nest calling to male. Female has very dark brown feathers. Male flew to her and landed on her back, mating. He flew away but came back in five or so minutes to mate again. Nest in good condition.
very large nest made up of mainly sticks and spanish moss, pair of ospreys sighted taking turns leaving the nest. Neither flew very far from the nest, and the male was seen bending his head into the nest, possible indication of hatchlings
After another fifteen minutes of observation, the status of the nest remains empty. No Osprey were present in the nest or even in the area. This nest is right up against 54th ave. which is a major roadway, this could be the reason why the Osprey choose elsewhere to nest. Despite their resilience to people, bird vs car does not usually end well for the bird, no matter how big they are.
Large nest, made from hearty materials such as large sticks. No manmade objects present in nest. Despite good condition of nest, no birds were seen for the ten minutes spent watching. No presence of Monk Parakeets either.
Today I observed a male osprey sitting in the nest. A female osprey then flew into the nest carrying a fish. Female began feeding juveniles. Male flew out and perched himself on a pole across from pond.
Today I found the nest for the first time this season. There was a female osprey perched on a branch that stuck out atop from the nest. The female was cleaning itself while also looking around. There was no sign of hatchlings.
Today I did not see any ospreys in the nest or on the other side of the parking lot as I usually do. I honestly have no idea whether the birds I have observed in the vicinity belong to the nest or not. I am very confused about this nest.
Today the nest looked to be deserted again however, we saw a pair in a tree across the parking lot. I don't know if that means that the pair was just taking a trip across the parking lot or if they were different ospreys.
