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.
Nest has not been added to since last observation. Again one pair of ospreys were sighted in the immediate area despite the presence of three closeby nests. It appears the pair has chosen another nest.
Pair of ospreys sighted perched on nearby light posts, both of which were observed screeching to each other before flying off. Unclear as to whether pair is inhabiting 4555, 4552, or 1185. Nest is very small and not well developed.
No other ospreys observed in area.
At first it was very hard to observe the female in the nest that is normally seen incubating but after waiting I spotted her. I found it very strange as if she may have added to the nest or moved around material that made her harder to spot by even just the head
There is a chick and an adult male present. They are low in the center of the nest and only half of their bodies are visible. The chick is small, brown, and downy. It is hard to tell whether there is a second chick or whether it is just nesting material moving in the wind.
A female osprey was present. She was sitting in the center of the nest, possibly incubating. On an adjacent light pole sat what appeared to be a male osprey. It was watching its surroundings, flexing its wings here and there.
Nest unoccupied. Today there was a tornado watch and many nests were unoccupied during observation period. There was an adolescent osprey (guessing it was young due to size) sitting on a nearby light pole with ruffled feathers.
I think this nest be the same nest that is currently being reported as #1185. The database says there are three nests at Bartlett Park but there are currently only two occupied. This nest was occupied by a female, laying low and flat backed. A male osprey was seen flying by, dropping something off as he briefly perched only to fly away in seconds. It looked like he was dropping by materials to build up the nest but it could have possibly been food.
Currently the pin is dropped to the right of the recreation house. When I arrived there was no nest on the platform of the right light pole. An osprey was present on the right light pole though. However, on the left light pole platform there was a nest. No birds were visible within the nest.
When I went to observe this nest today it appeared that there were still two ospreys around the area. A female Osprey was perched on the nest and the male Osprey was close by on another light post on the football field. The Ospreys that I saw today were not in the original nest that I believed to be incubating.
I do not believe that the nest is incubating. While I saw a female osprey in the nest the last time that I checked on the nest it appears the nest was empty this time. This being said it looks like a new nest might be being built on the opposite side of the football field on another light. I am curious as to whether this is a new pair of ospreys or if they have abandoned their old nest.
I observed this nest for quite a while and I saw that there appeared to be an osprey in the nest. The bird stayed low in the nest which led me to think the osprey might be incubating eggs. I also saw that there was a male osprey not far from the nest. He had a fish that he was eating.
