What to look for
a
Adult Arrival
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.b
Incubation Initiation
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.c
Clutch Hatching
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.d
Nestling Count
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 flye
Fledgling Count
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.f
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.x
Nest Failure
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.Review All Observations

Nesting Diaries
08/31/2021 by Feathers and Fauna
I was not able to confirm nest activities at this location this year. It looked like there was nest substrate on top of the tower, but I was unable to confirm a nesting pair.
05/10/2019 by Feathers and Fauna
This nest is very hard to see since it's on the top of a very tall pole. I'm not sure if an adult was sitting on the nest or not, but I did see an adult on the piping that crosses the C&D Canal during the observation period.
08/02/2018 by Feathers and Fauna
Still not able to determine any juveniles. Observed one osprey on nest and one on wire nearby.
07/11/2018 by Feathers and Fauna
Unable to see inside nest for chicks, but one adult present on nest for duration of my visit.
06/21/2018 by Feathers and Fauna
Two adults seen standing on nest during entire visit. No chicks visible if present.
04/25/2018 by Feathers and Fauna
Single adult observed sitting in existing nest! No mate seen during observation period.
04/20/2018 by Feathers and Fauna
One adult osprey seen during observation period. Sat on gas line bridge that crosses C&D Canal.
07/14/2017 by Feathers and Fauna
Observed spotted, fledged chick sitting on power line near nest for duration of observation period. One adult in nest and second adult flew from nest shortly after I arrived.
06/21/2017 by Feathers and Fauna
Saw 2 adults and one chick stretching on the top of the nest tower today! Added one photo of all three. Could not ascertain any additional chicks due to position of nest on that high tower!
06/09/2017 by Feathers and Fauna
Observed both adults today; one adult on nest, while the other adult was on nearby power line. Two new photos added. Could not see into nest, so unable to confirm eggs or chicks.
05/04/2017 by Feathers and Fauna
Unable to see inside nest, but found one adult on piping near nest. Adult stayed for 5 minutes, then flew toward canal, out of site. Providing photograph of nest location on top of light tower, and of adult osprey on wiring.
04/17/2017 by Feathers and Fauna
Nest was empty, but I observed one adult on the high wire crossing the canal. After about 10 minutes, it flew and called sporadically.
08/08/2016 by Feathers and Fauna
Empty nest today! Only found one adult hanging out on the power line over the canal. He/she stayed there during the entire observation period.
07/15/2016 by Feathers and Fauna
A CHICK! It's a big one, but has spots and reddish eye coloring. It was sitting on the edge of the nest during the whole observation period. It called often; an adult returned the call nearby. One adult was observed on power line over the canal, holding a fish. Photo of chick at nest and adult on power line attached today.
06/28/2016 by Feathers and Fauna
Still cannot see into nest to confirm any chicks. One adult at nest today during observation period. Second adult perched nearby on power line over the canal.
06/09/2016 by Feathers and Fauna
Saw both osprey at nest exhibiting mating behavior. Before flying to nest, one osprey chased a bald eagle and called at another perched in a tree across the canal. No chicks could be seen. Not even sure if there are eggs in nest.
06/02/2016 by Feathers and Fauna
Confirmed both adults at nest, although cannot see inside nest. One adult sat on wires near nest, while other adult stood inside nest. Unable to confirm either eggs or hatchings inside nest.
05/18/2016 by Feathers and Fauna
Watched nest for ½ hour and could hear osprey, but could not see any. This nest is on top of a tall tower, so it's not possible to see in the nest.
04/25/2016 by Feathers and Fauna
Ospreys present! Both adults appeared to be milling around the nest. One adult flew off nest and perched nearby for duration of observation time. Of note: large construction equipment is in close proximity to nest (see photo, nest is on white tower structure.) But fortunately, this pair is OK with the construction noise. Lots of BVs and TVs in vicinity, as usual.
04/06/2016 by Feathers and Fauna
Nest is visibly larger than last visit, but no osprey were seen during observation timeframe. Will check again in a few days, in the morning.
03/25/2016 by Feathers and Fauna
Observed one osprey actively bringing sticks to beginnings of a nest. Other adult observing from wire spanning canal. One bald eagle, 7 BV, and 6 TV observed in the immediate vicinity, but did not flush/pester osprey.
