Take Union Avenue to the end of Bayview Avenue and park on the right. Walk past the fire hydrant on the left end of Bayview and stand facing the creek. The low, man-made platform is in the near ground at 11 o'clock in the direction you were walking. A small feeder creek with a steep bank and reeds runs along the north side of Bayview. If you use a GPS device, set it for the intersection of Bayview AV & Beachview AV to avoid ending up in a different part of town.
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.
As I was driving on Jersey Avenue and nearing Rose Avenue, I pulled over in sight of the western edge of the IFF parking lot. I was where the telephone poles that run along the southern edge of the parking lot turn 90 degrees north towards the bay but again along the edge of the parking lot. It was at that corner that I saw a pair of osprey -- one standing atop a phone pole and calling incessantly and the other was spotted twice near the ground. Perhaps they are nesting nearby at this nest? I stayed for about five minutes and the one atop the pole didn't leave.
We had a nice chat with some local residents who have been watching this nest for several years. This year there was a nesting pair, and they had two offspring, one of which left the nest recently. One adult and one offspring were present this evening around 7:30 pm. I relocated the nest on the map, realizing that the nest is on the far side of the creek.
I went to the end of Bayview Avenue today and found a great spot for observing this nest. It is definitely occupied by at least an adult pair. One was on the nest when I arrived and another returned to the nest soon after. The newly arrived adult stayed only a moment and then left, apparently concerned about another osprey flying around to the north. The two flew in arcs above the treetops, then another osprey joined them, and another. I looked back to the nest and the adult was still there, so there were 5 adult osprey in the area. Two of the osprey formed a pair in the sky, one flew into the distance northeast and I lost track of the fourth, which I presume was the East Creek adult who'd arrived and left the nest. I noticed two nests at 10 o'clock in the distance, almost in line with one another. The first, presumably 139B (#2918), was on a platform attached near the top of a telephone pole with a street lamp. The far one, presumably 139C (#3007), was also a platform attached near the top of a telephone pole. I saw nesting material on each but couldn't see any birds. The adults flying around made no visits to those nests while I was watching. Presumably the other nests in this vicinity are better viewed from the waterfront, but I didn't have time to explore. The Bayshore Regional Watershed Council posted a Facebook event for 22 March 2014 to erect some new osprey platforms. They were meeting in the IFF parking lot on Union Avenue at Route 36 near Natco Lake but the event didn't specify where the platforms would be erected.
