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

8:55 a.m. I pulled into the bank driveway and saw that the nestlings had fledged and were not in the nest. Only the adult was perched on one of the posts.

8:03 a.m. Both chicks are now large enough to be seen from the PA side, closer up. I pulled into the bank driveway and since it was early, parked there. One chick was "branching" on a horizontal bar of the tower. The other was sitting up tall near the nest, on the tower platform. I didn't see the adults. It would appear that these chicks will soon fledge if they haven't already.

2:30 p.m. The female was perched on a tower post. One chick was up preening, the other was lying down and more difficult to see except when it moved.

11:40 a.m. The female was sitting on the nest with one chick to the north side of her way down. I could just see the top of its head. The other chick was to the south side and partially hidden by the tower structure.

11:38 a.m. From Old River Rd I saw what I thought was an adult at first, but moving slightly north and zooming in with my scope, I realized it was a big chick, sitting up tall! Another big nestling and the adult female were sitting to the left of the first nestling that I spotted! Two nestlings! I saw another adult soaring over the nest which was probably the male.

4:15 p.m. From the PA side I could see nothing in the nest. From Old River Rd on the NJ side I saw an adult sitting high on the nest as though brooding or watching nestlings. Its back was toward me so I couldn't tell if it was the female, but I would assume so.

11:15 a.m. There is no good viewing spot for this nest that I found in Pennsylvania. From the parking area at the bank or nearby on the road, one is so close as to be looking up at the bottom of the nest not at the birds in the nest. I saw an adult sitting on the nest, but with foliage now fully out, the tower is hidden except from quite far away. The chicks will have to be large before one can see them.

9:25 a.m. I drove around the bank parking lot and stopped a couple places nearby but there wasn't a good spot for viewing inside the nest. I took a photo from the NJ side on Old River Rd not far from the Holland osprey tower nest, but it wasn't clear that there was an adult on the nest as the photo was zoomed to the extreme.

2:08 p.m. As I was driving on Old River Rd in NJ doing osprey nest checks, I spotted a cell tower in PA across the river with an adult perched on the structure. I looked it up and there is a nest reported at that site.
