Posts Tagged ‘osprey nest’

Most of the nests of Ospreys(Pandion haliaetus) that I have seen in the past were in trees, but sometimes ospreys build their nests in readily manmade structures. On Tuesday I spotted an osprey couple that appeared to have taken over a nest on a channel marker in the waters off of Occoquan Bay National Wildlife Refuge.

In past years I have seen osprey activity at this same channel marker, but do not know for sure if ospreys were successful in hatching eggs there. The nest takes up only half of the space on the marker and there looks to be enough room to accommodate a second osprey couple. However, I doubt that the current occupants would tolerate the presence of neighbors that close, so it seems unlikely that I will see side-by-side nests in the future.

Earlier this season I saw a lot of Osprey (Pandion haliaetus) activity at Occoquan Bay National Wildlife Refuge. Many of the Ospreys seemed to be attempting to build nests, but it was never clear to me which ones were viable. These potential nesting sites were scattered around the entire refuge, so I count not simply monitor them as I do with the two eagle nests.

One of these sites is a man-made nesting platform that is located in the middle of a field. It is a simple wooden platform atop a vertical post that looks like a telephone pole. During the off-season, when the ospreys have departed from our area, bald eagles often perch on this platform, but it is not suitable for a bald eagle nest.

Apparently, though, the nesting platform is suitable for ospreys. Last Friday, I noted a lot of activity at the platform and managed to capture this image of an osprey family. I was shooting a telephoto lens, but was a good distance away, so the shot is not quite as sharp and detailed as I would have liked. However, it is easy to pick out both parents and at least two baby ospreys.

That same day, I checked the eagle nest to see if I could see the eaglet that I had previously photographed, but did not see it. Previously it looked like the eaglet was almost ready to fly and it is possible that the eaglet is no longer spending its time in the nest, but I will be sure to check for activity the next time that I visit the refuge—it is one of my regular stops when I make the rounds at the wildlife refuge.

Ospreys (Pandion haliaetus) were really vocal and active last week at Occoquan Bay National Wildlife Refuge.  Most often, though, the ospreys were flying out of range of my lenses, so getting shots of them was a bit of a challenge.

Eventually I manage to get a shot of some  perched ospreys. In the first and third photos, the osprey appeared to have a fish that it kept hidden from me. Perhaps it had had a recent experience with an eagle trying to steal its catch and consequently was hyper-possessive now. I think that attitude also explains why the bird was in a defensive, crouched position and would look around before taking a bite of the unseen fish.

The middle photo shows an osprey on a nest that is being constructed on a channel marker in the waters off of the wildlife refuge. In the past,I have photographed much larger nests on this same buoy—check out my blog posting entitle Defying gravity from last year to see a photo of a previous iteration of a nest at this spot.

In the last few days some local photographers have posted photos of warblers at this wildlife refuge, so I will be looking for small birds as well as the larger, more visible ones like these ospreys. Insect activity is beginning to pick up too, so it looks like April will be a busy time for me and my camera.

When I saw an osprey couple trying to build a nest earlier this spring on a channel marker in the waters off of Occoquan Bay National Wildlife Refuge, the building site seemed way too small. Amazingly the ospreys (Pandion haliaetus) found a way to add an overhanging extension that seems to defy gravity. The couple seemed comfortable in the nest, which appear to be capable of easily holding their weight.

A neighboring osprey couple had the opposite problem—they had too much space. The ospreys used only half of the space for their nest and could easily have shared the other half with another couple, but I think that ospreys like to keep their neighbors at arm’s length, or maybe it would be better to say “at wing’s length.”

Some of the newly-returned Ospreys (Pandion haliaetus) at Occoquan Bay National Wildlife Refuge were busy on Friday building or renovating their nests. In past years I have seen ospreys make nests in a wide range of locations, both natural as well as man-made. This osprey was ferrying out sticks to a nest on a distant channel marker in the bay, where its mate waited patiently for each new delivery.

It has been almost a month since I last checked in on the Ospreys (Pandion haliaetus) at Occoquan Bay National Wildlife Refuge. Last month they were busy collecting materials to build or repair their nests. Last Friday I spotted several nests that had grown considerably in size and the ospreys in the nests appeared to be sitting on their eggs.

I captured this image when one of the sitting ospreys had lifted her head to the sky, looking with hopeful expectation for her mate to return. Maybe he would be bringing her a fresh fish or perhaps he would be spelling her a bit from her maternal duties or could it be that she simply longer for his presence.

Sometimes Ospreys (Pandion haliaetus) will renovate preexisting nests, but often they have to build one from scratch. This osprey couple that I spotted recently at Occoquan Bay National Wildlife Refuge was trying to build one in what seemed to be a rather precarious location.

I learned about the location of the nest only when I spotted an osprey flying by me with a stick in its talons. In my zeal to track the osprey, I neglected to pull back on my zoom lens, so I ended up cutting off its wing tips in the first image in which the osprey is delivering the stick. In the second image, you can see the nest-to-be as the osprey attempts to arrange the sticks. The final shot shows the osprey arriving at the nesting site with another stick. I like the way that the osprey almost hovered in order to land softly with its delivery.

I don’t know it the osprey couple will manage to jam enough sticks in the crook of the tree to be able to form a stable nest, but I will be sure to check their progress in future visits, as long as the wildlife refuge continues to stay open.

Land prices are so high here in Northern Virginia that you have to be creative. Yesterday I spotted this Osprey (Pandion haliaetus) couple building their tiny house on one of the boundary channel markers off of Occoquan Bay National Wildlife Refuge.

The osprey perched in the back, which I believe is the female, remained in place while the other osprey flew off to forage for building materials. Sometimes they were only small twigs, but occasional the male osprey would return with a fairly long branch, as in the second photo. In the third shot, the male osprey has successfully landed with the long branch, but has not yet let go of it.

Multiple osprey couples are busily constructing nests all of “my” wildlife refuge and I hope to be able to share some images of their constructions sites.

Even though we were at more than an acceptable social distance, this Osprey (Pandion haliaetus) seemed to be communicating a message to me with its direct eye contact on Saturday at Occoquan Bay National Wildlife Refuge—something like, “Please leave so I can continue working on my nest.”

Most of the time I will try to avoid photographing a bird head-on, because it has the potential to distort its features a lot. With this osprey, though, I think it worked out pretty well, perhaps because of the size and shape of its head.

When it comes to choosing a nesting site, Ospreys (Pandion haliaetus) at Occoquan Bay National Wildlife Refuge seem to be opportunistic. Some lucky couples are able to snag pre-existing nesting sites that require only minor improvements, while others are forced to build entirely new nests.

This past Thursday I photographed a nest that is annually built on top of one of the duck hunting blinds in the waters off of the wildlife refuge. Earlier in the season, the ospreys would fly away as I walked by on a trail, but now that the trees are leafing out, the ospreys have a bit more privacy.

The nest in the second image is a new nest, built in the last couple of weeks and probably still under construction. It is adjacent to the location where the nest in the third shot used to be. For reasons that are not clear to me, that nesting platform has disappeared and only a part of the post remains. I believe that the new nest may have been built by  the couple that occupied that nesting platform earlier in the season.

Saturday morning at dawn I noted than an Osprey (Pandion haliaetus) had already claimed the most prominent nesting site at Occoquan Bay National Wildlife Refuge. There are several man-made nesting platforms scattered through the wildlife refuge and there are usually some additional osprey nests in trees and one on the top of a hunting blind on stilts in the water. This particular nesting platform is visible from the parking lot, so it was easy to check to see if it was occupied.

Most Ospreys (Pandion haliaetus) at Occoquan Bay National Wildlife Refuge are busily building nests high in the trees, but at least one chose a location that is almost at eye level. The nesting site is on top of a duck blind not far from the shore. The blind is essentially a small wooden shack that sticks out of the water on stilts or pilings.

The nice thing about seeing a subject at eye level is that it gives a very natural perspective that helps you, I believe, to engage more directly with that subject, literally seeing eye-to-eye. That is why it is usually recommended that you bend down to photograph children and pets.

In theory, it is easier to get a shot like this that to shoot upwards into a mass of foliage. In reality, though, I had to find a big enough break in the vegetation and shoot over a chain link fence topped with barbed wire, while moving stealthily so as not to disturb the skittish sitting osprey. I ended up stopping by the spot multiple times during the day before I finally got a shot that I liked. (For what it’s worth, I am not sure what the object in the foreground is—at first I thought it was a partially eaten fish, but now I don’t think that is the case. Any ideas?

Like many other places, Occoquan Bay National Wildlife Refuge has some raised platforms on which ospreys (Pandion haliaetus) build nests each year. Sometimes violent winter weather destroys much of a previous year’s nest, but quite often the nest survives pretty much intact and all that is required is some spring cleaning and minor renovation.

The latter seemed to be the case with one of the osprey nests that I spotted this past Monday. An osprey was in the nest and appeared to be moving around some of the branches. In the first shot you can see some of the man-made elements of the platform on which the nest is constructed and get a sense of the relative size of the nest. I couldn’t get a really good look at precisely was it doing, though, because the nest was high in the air on a tall post, as you can see in the second photo below.

As I was watching the osprey, a bald eagle flew by and seemed to startle the osprey. The final shot captured the osprey just after it took off from the nest and really emphasized the massive wingspan of the osprey.

Ospreys (Pandion haliaetus) were really active yesterday morning at Occoquan Bay National Wildlife Refuge, including this one that was gathering materials to either build or repair a nest.

Initially I was standing next to a field that had been cleared some time ago, when an osprey swooped in and snatched up some branches lying on the ground. I was surprised and remember wondering if the osprey would return to the readily available supply of building materials. The osprey returned two or three more times and I was able to capture some cool shots of the osprey transporting some pretty large branches. I was pretty fortunate that the osprey had to fly almost directly over me when it was making its return trips to the unknown nesting location.

There are several nesting platforms in the refuge for ospreys and later in the day I spotted an osprey in one of them. The nest seemed to be pretty much intact from last season, though the osprey seemed to be busily making adjustments and probably was doing some spring cleaning. That may be the subject for a future blog post.

A Bald Eagle (Haliaeetus leucocephalus) was being harassed relentlessly this past Monday at Occoquan Bay National Wildlife Refuge by a flock of crows and was eventually forced out of what I assumed was its nest. Fortunately I was able to capture a couple of shots before the eagle left the nest.

When I posted a photo in Facebook, a more experience birder pointed out that the nest is probably an osprey nest, not an eagle nest. He added that eagles at the refuge often will perch on osprey nests when the ospreys leave the area for the winter.

The final photo, taken through the trees, shows the crows occupying the nest after forcing the eagle to leave the exposed position.
