Nesting Diaries

The female bird continues to incubate the eggs, rolling them from time to time. The male is always close by. For the last three days two osprey (sometimes only one) roost on the cross bar post across the marsh almost directly behind the nest. They have not flown toward the nest, but are on the cross bars for the entire day - at least one if not both. The osprey in the nest do not exhibit any signs of distress during the day.

Since the 5/06 entry until 5/15 each day continued the same routine as the 5/6 entry. This pair work well together. On 5/15 around 8 AM an osprey was spotted flying towards the nest being monitored. The male osprey, who was in the nest with the female spotted the oncoming bird and flew directly towards it. They seemed to make contact for a moment, and then the oncoming bird turned away and flew across the marsh to the west. The chase continued until the bird from the nest had herded the other osprey to the western most bank of land. He then turned back towards the nest I'm monitoring. Rather than landing in it, he stopped short of it by about 20 feet, landing on the ground facing the nest and stayed on that spot for the rest of the day. The female remained in the nest during the latter part of the afternoon, when the male came to the nest and took her place. The next morning the male osprey was sitting in his previous spot on the grass, when an osprey came flying towards the nest from the west. Since the osprey from the nest sitting on the ground was facing west, he spotted him approaching. The Osprey in flight kept coming, but the nest bird did not let him get close. He flew towards the oncoming bird and chased him back towards a western strip of land. Then he returned to his position on the ground. He has sat in either that spot or another a little further out where he can see the nest but is facing north. The bird from the west has not returned since his last attempt, at least during the times I have been monitoring the nest. The female has sat on the nest for much longer periods of time than she had been. On the very windy days, she lies flat and stretched out. I assume she is incubating some eggs, but these birds never leave the central nest area open to view.

Since the last entry, this pair has settled into a routine of taking turns sitting in the nest and sitting on the nearby small roost, flying in the area, and bringing fish back to eat on the roost or take into the nest. This morning the female was sitting in the nest when the male flew into the nest and stood beside her, as if ready to take over for her. She did not acknowledge. his presence. After about five minutes, he gently pecked her beak. She looked around and saw him there, immediately stood very high in the nest. He slid in under her belly as she moved forward and flew. Quite a coordinated move! As a pair, these two osprey seem compatible and to understand and accept their roles!

The male osprey sat on the nest most of this morning. The female returned around noon and stood beside the male for a while before he stood up and flew off. She then took over and has been sitting there for these last few hours. The male has spent most of his time on the ground close by the nest.

Since the last entry, he female has spent more and more time on the nest and the male has spent short periods of time in the surrounding area either sitting on the marsh close to the nesting platform or out over the water. Today for the first time the female sat on the nest for the first half of the day, and around 1 PM the male flew into the nest with her bringing a fish! She stood up, stretched her wings, an flew off to the roosting post close by. The male dragged the half eaten fish over to another spot and proceeded to claw at the center of the nest. Then he sat on the center of the nest and remains there until now, about 5 PM. The female returned earlier, but has been roosting on one of the crossbars beside the nest.

Until yesterday,4/25, the routine previously described continued. Yesterday the behaviors changed. The male and female appeared to be functioning separately. They chose posts that were opposite each other to perch on throughout the day; one would leave the other alone in the nest consistently, one of them would bring his/her fish to the roosting post and the other was either in the nest or off somewhere on the marsh. At one point the female sat in the nest for a short period of time as if she were incubating eggs, but that only happened once. Today the behavior was similar until this afternoon, when the female began bringing nesting material and arranging it in the nest. The next time I saw her she had begun sitting again, as if incubating eggs. The male flew to the nest, would stay for a short while, and leave. The wind began to increase later in the afternoon, the sky darkened, and it seemed as if a storm was approaching. The male flew but the female stayed on the nest, I don't know how long she remained, but clearly, it was a change in behavior.

Up until today the days since the last entry have been routine. The osprey do everything together now - nest building, sharing a fish usually caught by the male, sitting together on the marsh, flying off together, etc. There were four more unsuccessful attempts by the male to mate that I have observed - he slides off her back each time. Today the female was in the nest alone for the first time in a while during the times I have been observing, and two osprey came flying low out of the south towards the nest, one behind the other. The first one flew low over the female osprey in the nest, and the second one landed on her back and tried to mate with her. She cooperated. He was there for what seemed like only seconds and flew off. She stood alone in the nest, and eventually the male osprey who she has bonded with returned. I could not tell whether the osprey who tried to mate was the one she seems to have bonded with. I will just add that the two osprey without a nest have remained as a pair on the western edge of the marsh, bringing the fish that are caught back to the same general area to eat, and sitting for periods of time in the grass. I do not see an attempt to create a nesting area in the grass with additional material placed on top of it. I do not know whether the male who tried to mate with the female in "my" nest was the male across the marsh.

For the past three days there have been no more attempts by the two osprey without a nest to take over the nest already occupied. It appears that they have chosen to "nest' permanently on the far west bank of the marsh, consistently return to that spot with fish. Yesterday I had them in my scope, and they were mating. As they eat their catch of fish on the ground at their nesting sight, they are constantly mildly harassed by four or five gulls. The two birds in my nest are constantly together now whether in the nest or on the marsh. They are engaging in nest building, with the male bringing materials to add to the nest. Yesterday the male brought a fish to the female, and as she began eating it, he attempted to mate with her and tried to mount her. However, he kept sliding off her back. She quickly realized what was happening, stopped eating, and arched her back to a more level position by bending her neck and head down towards the nest. The male made four more attempts, and she remained completely still throughout. He still kept sliding backwards and onto the nest. On his fourth attempt, she curved her neck and head to the left, and pecked at the upper part of his left leg, seemingly in frustration at his lack of skill at mating! He immediately flew away, and she followed! But wherever they go, they are together now during the times I have observed them.

Today was the first day there was no attempt by the outlying osprey to take over the nest already occupied by a pair. However it is clear that the two who challenged the occupants do not have a nest, and thus their attempts to overtake one. They huddle together on a bank of the western edge of the marsh, flying off from time to time, but always returning to the ground in the same location.

Another challenge to the nesting osprey was made by a single osprey and chased away by the male nesting bird. He was positioned outside the nest on the ground in the previous location. At the same time a red fox appeared, and the nesting male osprey dive bombed him once he had chased away the bird challenging him for the nest. The female remained in the nest throughout.

Yesterday and today were days of the pair of osprey spending some time together in the nest, sometimes separated with one in the nest and one fishing for a meal, and sometimes both away from the nest. They did not make a mating attempt during times I was observing them, which is not say it didn't happen. Then, later in the afternoon, a lone osprey came flying in fast from the west, and directly flew into one of the osprey in the nest. Both of the nesting ospreys flew at the intruder and a fast and furious chase began in the sky above the nest. At one point, with the nest empty, the interloper dropped down into the nest, standing up tall in the center of it. He was immediately crashed into by one of the other birds, and flew up into the sky, but not off into the sunset. At this point a fourth bird joined the sky battle. This went on for about another ten to fifteen minutes, when two of the birds flew off, and one of the two original birds inhabiting the nest returned. I could not find the other bird with my scope, and she was absent almost until sunset. I continued to look for her in my scope, and shortly after the other bird returned to the nest, I noticed the fourth bird who had joined the sky battle, sitting on a crossbar post far across the marsh. I'm sure of its ID because it was larger than the three osprey. It was a juvenile bald eagle! This fight and flight episode was followed by another one around 8:30 this morning, but two osprey flew at the two in the nest, and was followed by about a 20 minute chase in the air. At one point a male osprey had pinned the other male into the bank along the bay. It was low tide. When the two intruders finally flew off, the male osprey returned to the nest. Again, I could not locate the female. After a couple of hours she returned, and the routine of the previous day was resumed.

The two osprey spent little time on t he nest together today. At one point the female was eating a fish on a part of the marsh that is somewhat distant from the nest. But the. male was spotted in the same area about fifty yards behind her sitting in the grass, as if keeping close watch on her. At other times one would be in the nest without the other. Later in t he afternoon they both appeared in the nest and he mounted her. She stood still, but after about a minute he flew off, and she stayed in the nest for a short while and then flew off. Neither has returned to the nest yet, about three hours later.

Since Sunday 4/3/22 the two osprey have been behaving as a "couple". They are on the nest together, fly off together, and are together when a fish is brought to the nest for a meal. Only one eats at a time. The female has been encouraging mating, but I have not seen it happen. Also, altlhough I obviously could have missed the mating attempts, she continues to try to encourage the male by standing in front of him and flapping her wings, standing in front of him and shaking her body, just standing in front of him and looking over her shoulder towards him. He stands there for a while, and then flies off for a while! I was gone most of the day, but I will say she was in the nest alone late this afternoon, and for the first time I saw her sitting calmly. There is not any nest building going on with the exception of a large bare branch the female brought to the nest on Sunday. She laid it along one edge of the nest, but by today (Wednesday) it has fallen under the nest between the crossbars on the post.

This is my first year of reporting on this nest, but I have been observing it unofficially since 2011. It has been occupied by osprey who each year until 2018 have successfully raised. 2-3 chicks. Since 2018 once the osprey have mated and either are sitting on the eggs or have hatched nestlings, the nest has been attacked by two osprey who either destroy the eggs or kill the chicks. The male occupant of the nest always puts up a valiant defense, while the female tries to protect the chicks or the eggs. This year the post used as a roost by the two intruding osprey is being removed in the hope that the pattern will be disrupted. The osprey who occupy the nest are not the same pair each year, but the aggressors appear to be the same. Yesterday, March31, at 8:15 AM a male osprey flew to the roost near the nest and proceeded to eat the fish he had been carrying. He then flew to another post across the marsh, and stayed there for about an hour. Then he flew across the marsh and out of sight. He has not yet returned.
