The great blue
















This heron looks fabulous but the photo at left hides the story.
The bird has sores on many places on its body. In this pose the long feathers hide them, but a close up of the foot tells the tale.
Also when the feathers are blown back there are areas on the body where it looks like there are open sores.
I don't know what this is. Many birds molt, and change over their feathers at this time of year, but that's not what it looks like.
This heron hangs out at a marina in Nanaimo, near industry and heavy recreation use. 
Herons seem to have adapted well to living amongst humans. They are seen everywhere on the B.C. coast, but they are listed as a species at risk both provincially and federally.

Empty nest

I returned on Saturday to an empty nest.

I scanned around until I located one of the young osprey sitting on the line of a ship docked at the port.
It cried a bit then flew off in the direction of the fishing grounds just over a small rise where the river pours into the sea.

I packed it up and went to see what the family was up to on the other side and it was like a different world.

At low tide, pools of water glittered on the mud flats. Rather than concrete and metal of the nest site, it was all water and trees.

The location of the nest was pretty unpicturesque but the fishing grounds were gorgeous and situated in such a way that I thought the parents could keep an eye on the nest while foraging.



If so, both male and female would be able to provision the chicks earlier in the season. The typical osprey nest sees the female standing guard against chick-eating predators for months while the male runs himself ragged feeding the whole family.

If this pair have found a way to do both at once, that would be a significant advantage. 

That would make an extremely interesting research project.

The fact that all four birds now spend time at the estuary means they may not be at the nest anymore. They are much more difficult to spot spread out over a large bay than sitting on top of a light standard. 

Soon they'll be headed south. Osprey I've watched previously depart in early September for their wintering grounds in central and south America.

I may see them again, or I may have to wait until next spring.

Help in high places


I started eyeing up the big orange structure and assessing the many stairs on it just before Mark and his assistant wandered over. They were employees at the port-loading facility and I thought this might be the part where I was asked to leave.

I was dead wrong.

The pipes over my head had been rumbling and the two men were checking to make sure something came out the other end. They stopped and we chatted for a while. Mark told me the real name for the big orange thing – container crane – not as technical as I would have expected.


He suggested that would be a good place for me to be. I agreed and he gave me the number of the "guy that owns the thing." I couldn't imagine one guy could own anything of the sort. 

This crane must be over 30 metres in height. You can see it from just about anywhere on Nanaimo's waterfront.

I had written off the idea of gaining access as ridiculous, but the thing is, if you ask, people usually help you out. In fact, I didn't even ask. It's got something to do with the birds.

I took the number knowing it would be a weekday thing to set up. As I discovered the next day, there  might not be another week with the osprey.

The family tree

Ok, Ok I had it all wrong.
On return to the nest last weekend the situation quickly revealed the family's structure.

On arrival there were two osprey on the nest, crying incessantly. That makes them chicks but I never would have guessed it by size.

For some time they just sat waiting for their fish to be delivered.
At last they got off the nest and flew around chasing eachother in what could have been play or could have been a more sinister kind of sibling rivalry.



It's not uncommon in raptor nests for the stronger nestling to do away with the weaker, but that's much earlier on.

These two are pretty much full-grown and not likely to risk injuries from a battle with a nest mate.




As they flew, the rope-tangled talons came into view, meaning it's one of the young with the problem. But she's huge. I would never have believed that was this year's offspring if the parents didn't come along shortly thereafter.

Until then, the fledglings soared around taking pot shots at eachother but once they heard the call of a fish-bearing parent they rushed back to the nest.



From that point on it was a steady stream of what looked like perch brought over by both adults.





Five fish came in the 30 minutes I stood there watching. The adults were still out fishing when I left to get my dinner.

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 II

Next I headed out toward the Nanaimo Lakes area where I had looked a few weeks earlier.

That search ended at a TimberWest gate where a nice young man told me I had to pay two dollars to continue to the lakes.

What? A logging company, given public forest land for free by the B.C. government, now wants to charge me to go to the lake?

I don't think so.

I ended up looking along the Nanaimo River that day with no luck. Had a really nice swim, though.

The rumoured nest I was looking for was supposed to be in a patch of woods that had a no trespassing sign on one access point, which I skirted around until I found a path on the other side.

As always, prepared for my task, I tiptoed over thorny blackberry vines in sandals leaving trails of blood.

No osprey.

But the man at the wharf told me about another nest out at Duke Point, where the ferry runs from Nanaimo to Tsawwassen. He said I could get permission to visit the site when the port office opened on Monday.

Right.

Off to Duke Point.



I'm not going to say how I knew about the first two locations. OK, I will. I Googled ‘osprey nests in Nanaimo’ and they were pinpointed on Google maps. Ahhh, the cushy life of a modern naturalist.

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.

Success at last

Oh finally. I have found an osprey nest.

It's not quit what I had expected – it's in Nanaimo in a heavily industrial area – but I got my fill today.

That's not true.
I got a taste and there's a story that goes along with the 115 photos.

For now, here's a look at what makes my heart beat faster.

Birds I take for granted



Cormorants fall into that category but like anything, start digging around and there's an interesting story there.

I saw these colonies of double-crested and pelagic cormorants during a lovely harbour cruise out of Nanaimo with my mother.



The birds live in impossibly small cliff nests on the west side of Gabriola Island.

Cormorants are unusual among seabirds in that they don't have waterproof wings. That's why they are often seen sitting on rocks with their wings spread out to dry.


Most birds get their waterproofing from the fine structure of the feathers but waterproof birds are buoyant birds. The cormorant trades being dry for the ability to dive to depths of up to 40 metres.

Under the water they are agile swimmers and pursue fish and small invertebrates.

Young cormorants in colonies form groups called creches that they hang around with when their parents are out gathering their food.

Cormorants, and especially their young, don't make it hard to imagine their reptilian link to the dinosaurs.
