Osprey Nest Fight Over the Salt Marsh

NOTE: This post is publishing while I am away in Bequia, Saint Vincent and the Grenadines, where the X-T5 is getting its first proper outing. Posts this week were scheduled in advance. I was out watching the American Oystercatchers when I noticed it — a rough tangle of sticks on a wooden platform across the marsh. I trained the long end of the Fujinon XF150-600mmF5.6-8 R LM OIS WR on it and tried to make sense of the shape perched at its centre. It looked like an Osprey. But I wasn’t certain, and at that distance, with heat shimmer off the water and a wind that kept nudging the lens, certainty felt like a lot to ask. Then a second bird appeared from somewhere off to the right, and everything changed.

I don’t know for sure what the dispute was about — whether one had returned to find the other had taken up residence, or whether this was a territorial challenge between rivals. Ospreys will fight over a good nest site, particularly early in the season. But I couldn’t read the details at that range. What I could see was that neither bird was backing down quickly.

The Fujinon XF150-600mmF5.6-8 R LM OIS WR is not a light lens, and by this point in the day my arms were already carrying a fair bit of fatigue. The wind had picked up enough to catch in the lens hood, which introduced a low-frequency wobble that the OIS worked hard to counter. I shot anyway. Some frames were lost to motion blur or missed focus. Some weren’t. Then both birds lifted off together, and for a moment I had two Ospreys in the air above the platform — wings fully spread, talons out, circling and banking against a clear April sky. The coastal town across the bay sat hazily in the background, its water tower just visible, and the salt marsh grass in the foreground held that flat, winter-straw colour it keeps until the green finally comes in. It was one of those compositions that assembles itself without asking permission. The fight went on longer than I expected. One bird would land, then launch again. The other matched it. I kept shooting. My arms kept protesting. Osprey · Saturday 11 April 2026FujiFilm X-T3 · ISO 640 · 1/1000 secXF150-600mmF5.6-8 R LM OIS WR · 364.5 mm · f/13 Eventually, one of them gave up. There was no dramatic ending — just one Osprey banking away and not coming back, and the other settling on the nest with the calm of something claimed. I watched for another minute or two, then lowered the lens. It was the most engaging part of the day, which had started quietly enough with a handful of Oystercatchers on the shoreline. I had not expected to find an active Osprey nest, let alone witness what looked very much like a contest for it. That is usually how the good sightings go — you turn up for one thing and something else entirely holds the day. I was glad I had the long glass with me. I was also glad to put it down.
