Sitting on gold

Me and this female osprey nesting at the Esquimalt Graving Dock, a federal ship building and repair facility near Victoria, B.C.

Like the UVic osprey, this pair has chosen a busy place to arrange some sticks on a light standard. They live on an industrial dock where large vessels like cruise ships and ferries get hauled out of the water for welding, painting – you name it, it's happening while this female defends and feeds her young and the male delivers fish and hangs out on a nearby tower.

What struck me immediately about the graving dock, is just how clean it is. The Environmental Services Department takes its work seriously. They keep an eye on all the wildlife that transit through or live on the site. Measures are taken to keep green corridors open for the movement of deer, raccoon and otters. Great care is taken with the many hazardous substances used around the ships, to keep it from poisoning the water or land.

Everyone there seems pretty keen about the osprey and keep tabs on the nest with a security camera. Activities on the nest, used intermittently since 2006, are logged and staff want to do whatever they can keep the site suitable for osprey generations to come.

Meanwhile, I've got a boatload of pictures that I have to sit on until I have a market for them. But I can't resist sharing a few now.


Thanks to the Public Works and Government Service Canada people for putting me up in the air with the osprey.

Fruitful searches part IV

Back on the boat, editing photos, I could zoom in on the rope and got more concerned as it looked like it had been tight on the upper leg and rubbed feathers away and into the skin.

My instinct always is to leave well enough alone, but I didn't feel right knowing she could be in trouble and not consulting someone.

I ruled out the government agency. I pictured nets being dropped from a helicopter on an animal who can likely solve her own predicament.

I looked up the local rescue agencies. Rang one number, no answer. No surprise on a Saturday evening. I didn't leave a message.

Within ten minutes, Lorinne called me from Second Chance Wildlife Centre. I gave her a sketch of the situation.

"Is she flying?" she asked.
"Oh, yeah," I said
"Then that's it," she said.

They wouldn't attempt to catch a raptor on the wing. Whew, I liked that answer.

We talked for a while and she told me about a recent rescue of a juvenile osprey.

The bird had landed on the Gabriola ferry with the marks of an eagle attack. Lorinne retrieved the bird and immediately shipped it by floatplane to O.W.L. on the mainland in Delta, B.C.

She asked if I was around for another day as the bird would be back for release soon and would I like to be there?

Tough question, that part of me that doesn't agree with the interference goes against the other part that wants to be as near as possible to these birds and the part of me that believes that wildlife rescue, when done well, helps keep some populations going in a human-dominated landscape.

She said she'd call over to O.W.L. to find out when the release would happen.

It seemed the young male didn't know how to fish yet and they wouldn't free him until he did. There were training sessions going on with a pool and goldfish. Lorinne said osprey are hard to rehabilitate because they are fussy eaters.


As for the entangled female, O.W.L. reported that if she couldn't free herself, she would eventually get into trouble. They said her mate would feed her but eventually give up if she couldn't pull her weight.

Lorinne and I both wondered whether the rope had come from someone trying to catch her.

I gave her the nest location so she could monitor, or get people who work at the port facility to keep watch.

If she comes to ground exhausted or hurt, they will pick her up.

Looks like weekends in Nanaimo will be the new regime. I hope the rope is gone when I see her next.

Fruitful searches part III

For the Duke Point trip, I had no map. I drove all around the industrial park and the ferry terminal on the little finger of land poking into Georgia Strait.

Heading down the last road, I ended up in a log-sorting yard on the water next to what looked like a mountain of salt and a huge, red, ship-loading structure (not the technical term).

Ready to call it a day I sat, looked at the log booms and containers on barges sitting in the bay.

A dark figure perched on a nearby rail caught my eye.



To the untrained eye, it could have been an immature sea gull, or a bald eagle, but I knew immediately that the white speckles on the brown back meant one thing. Osprey.

I quickly got my camera out and photographed its back in case that was all I was going to get.

It soon tired of my attention and lifted off, and I was prepared to be thankful I saw anything until I followed its flight to the top of a light standard in the middle of the huge concrete loading area.

It flew to the sound that had been nagging me from over my left shoulder. The sound of big, hungry, young osprey waiting for fish.



It was more than likely the male I first saw, quickly getting a bite of fish before delivering the remains to the mob on the nest.

From what I could tell, the female and one nestling were up top and once they tore into the fish the flapping and crying stopped.

Sometime later I saw two on the nest with two perched nearby, suggesting the typical brood of two young but they were so big, it was hard to tell who was who.

Also, the band of dark feathers at the neck that usually signifies a female seemed to be present in all of them making it more difficult to decide who was the mature male and who a big chick. The female adult stood out because she's bigger.

She stood out for another reason, too.

After the feed, two birds came back to my level at the rail. The mature female seemed to be carrying moss in her talons. Nest repair? A bit of a surprise as what would have been a deep cup nest earlier in the year was now flattened. The platform was more like a meeting place than a shelter. Fledglings and adults don’t need a nest, just a fish-delivery point.

As the female passed over me, I could see it was rope tangled in her feet. Closer still and I saw it was old yellow polypropylene, about a quarter inch, that she'd been worrying at.


It's surprising she couldn't free herself with her razor-sharp beak. Then again, I couldn't know how long she'd been dragging it around.

I continued snapping, wishing I could just cut that rope off her, but she didn't look distressed or bedraggled. I watched for a while longer and left them in peace.

Fruitful searches part I

At long last I have found an osprey nest.

I have been, somewhat casually, tromping around lakes and wading up rivers around central Vancouver Island looking for something that is often conspicuous. When I found it, it was.

I had two leads to follow around Nanaimo – the Port of Nanaimo Assembly wharf and a cluster of trees just off the Island Highway.

I started at the wharf, a huge loading area for heavy industry right downtown and next to the Gabriola ferry terminal. I checked in at the commissionaire's office. Locked. No surprise on a Saturday.

So I drove on out passed the many 'NO UNAUTHORIZED PERSONNEL' signs until the guy in the green truck raced over with an amber light flashing and stopped me.

I find there is nothing wrong in these situations with using a little female charm and he led me to where a nest had existed earlier this summer. It was right at the water's edge, high up on a light standard with a flat platform on the top. An invitation to osprey.

He couldn't help himself. He told me how it had two chicks but that the parents abandoned them. They still saw the osprey around, he said.

What may have been seen as abandonment may simply have been that the chicks were ready to fly. I didn't get the whole story from him.

For now, there were no osprey around. I decided I could call back to learn more and continued on my search.
