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

possible failed nesting, not seeing any chicks tho both adults on nest again today
03/26/2021 by baygirl
have consistently seen one osprey, today one eating on nest, S 20 mph, 80, sun, 10 am 4 pm
09/15/2018 by baygirl
one osprey on the nest perch today but could not comfirm if it was adult or juvenile
08/08/2018 by baygirl
pretty sure this chick fledged before today but i just could not confirm it, finally saw it make a short flight around the cove and land, it looks like a newbie in the air!
08/03/2018 by baygirl
Since I am monitoring a foster osprey in a nearby nest I have been watching this chick starting to exercise and move about in the nest much more lately, standing on the nest edged and self feeding with adult female watching from the other side of the nest. this chick should fly soon.
07/15/2018 by baygirl
6 pm, 1 adult on the corner board of the platform, second adult, most likely female feeding just one chick in the nest.
05/19/2018 by baygirl
continuing to incubate, the second is often perched on the corner board of the platfrom.
05/04/2018 by baygirl
Finally today around 4:45 pm I saw one osprey deep in the nest and the second on the platform t perch. When I returned about 45 minutes later both were still in the same position. Definitely incubating posture. As I watched I scanned the cove and there were 2 other pairs out on the channel markers trying to build nests. Beach Cove is a popular osprey hangout.
04/29/2018 by baygirl
both coming and going to the nest, they eat their fish in the nest. no signs of nest bowl prep
04/02/2018 by baygirl
Pair was on platform today, one on t perch and one in the nest but no signs of incubating.
03/19/2018 by baygirl
Both osprey on nesting platform around 2 pm today. One appears to be eating. Saw one nest building few days ago as I passed on Rt. 1
06/08/2017 by baygirl
no nesting but the pair sits on the corner boards of the platform most of the day
05/22/2017 by baygirl
if they were incubating then the nest failed around may 14th when I saw one on the nest and one nearby. today I can confirm both up on corner boards of the platform, one with fish. I came past again later and still they were both on the corner boards. we have had quite a bit of rain last few weeks and this may, or may not, be the reason for nest fail.
04/17/2017 by baygirl
I believe this pair is incubating but it is becoming difficult to see the nest from the road, Route 1. once my boat is in water I will confirm
04/10/2017 by baygirl
pair has been off and on nest, sometime only one seen for long periods of time, may be a young/new pair
