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 was no sign of an osprey in the nest or on the light structure. There were a few other osprey in the area, but it is hard to determine which nest they belong to because it is so condensed in this area.
One adult and nestling easily visible. The nestling is growing rapidly. Upon arrival the adult flew the nest, circled, and landed. The adult flew away after ten more minutes. After the adult left the chick moved from the edge of the nest to the center.
There are both adults in the nest. The nestling is quite large, brown, and fluffy. It is ruffling its feathers and adjusting itself. Over the course of twenty minutes the female and chick sat down in the center of the nest and the male took flight.
One adult osprey seen tending to one nestling, feeding or grooming the young. Though two nestlings were observed a month ago, since that sighting there has only been one nestling visible. The adult osprey got up and flew away to perch on a nearby telephone wire.
Overcast, drizzling weather. No osprey visibly present in this nest. Perhaps the weather offered a good hunting opportunity. There was a little bit of movement in the nest, which were probably the nestlings sighted in previous weeks.
From the normal vantage point it appeared as if there were osprey present. However, upon walking to a nearby nest and glancing back with binoculars a female was apparent sitting in the middle of the nest. The head of one nestling was briefly seen when the female readjusted herself.
Both male and female osprey were present. Quickly after arrival the male circled, flying ~10ft above me. While the male astutely circled the nest the female was seen tending to nestlings. Two nestling heads were briefly visible. The male repeatedly circled and returned to the nest.
Male osprey perched next to the nest platform on the light pole, and did not move. The female osprey was perched on the side of the nest and seemed to be interacting with nestlings inside of the nest. Unfortunately the nest is very high up and I couldn't get visual confirmation of actual nestlings living in nest. However, the female osprey was bending over nest and opening beak and interacting with most likely two young.
There was a male and a female osprey in nest. Male was perched on side of nest, occasionally shuffling feathers and shifting position. Female seemed to be in the incubation posture with a flat back. Neither birds left the nest
