A juvenile raven comes calling

A family of ravens lives in a tree down the street from me.  I have often seen what I believe to be the same pair overhead for the past several years, often just enjoying flying around.   There are other ravens around, of course, and I often see them overhead or in the trees in the bush park near my house.

On July 11, while on a walk in the bush park with my camera, three ravens flew overhead. Then this young raven, flew down to a branch near me,  frequently calling for its parents while they remained high above in the tree tops.

A juvenile steller’s jay learns to crack a nut

 

Updated

I am lucky enough to be surrounded by the magnificent steller’s jay.   A group of them live in a tall conifer across a small park from my house.  (Unfortunately BC Hydro contractors opened up one part of the tree while rewiring the neighbourhood so the steller’s jays in that tree may be vulnerable.)  Others frequently visit (and may be living–I am not sure) in the cedar trees that mark the boundary with my neighbour’s house.  So the steller’s jays are frequent visitors to the feeder on my back deck.

I’ve been photographing steller’s jays on my deck,  in my backyard and in the bush around Kitimat for the past eight years. So I must have thousands of steller’s jays photos spring, summer, fall and winter for those eight years.

Friday night was a beautiful summer evening. I spotted three steller’s jays in the grass of my backyard.  I grabbed a camera, stepped out and saw–and heard–something I hadn’t seen in eight years.

For my feeder I used a wildbird mixture that it is mostly sunflower seeds, maize and shelled peanuts.  Although steller’s jays love peanuts I have never left out peanuts in the shell. But one of my neighbors does and I have seen from time to time a steller’s jay with a peanut in its mouth, usually on the ground before flying off into the trees.

What I saw Friday night (again Monday night) was entirely different.  One steller’s jay had found a way to crack the nut case in my old rotten fence.   Tonight there were two at it.

First about the fence, it’s old, probably original to the house when it was built in 1960, with parts rotting away and falling apart.  I had planned to replace it this summer but then I had to pay for major car repairs. Before that it was a new roof and a new furnace.

Steller’s jays, like all corvids, are highly intelligent birds.  It seems that scientists studying corvid intelligence, when they are not studying ravens and crows, concentrate on the scrub jay, which means British Columbia’s beautiful official bird doesn’t get much scientific respect with only a few university researchers looking at the bird (at least that is what I could find out in an online search.)

On Friday evening, that one steller’s jay found the perfect place to anchor a peanut in the shell.  My rotten old fence.

I asked Professor Jeffrey M. Black who does study steller’s jays at Humboldt University in Arcata, California what the jays were doing:

All three jays in these photos are of juveniles; note the fluffy grey chests and behind legs, and the yellow skin at the corner of the mouth. You may have noticed them giving odd raspy juvenile type calls too. Sometimes the young jays at this age, which come to feeders with peanuts, ignore peanuts and sample the seeds instead. It seems they get ‘turned on’ to peanuts through ‘social learning’ – meaning they observer others and learn there’s food inside. Seems like the young jay in the photos was new to the task. Experienced jays seem to extract the nuts from peanut shells quite quickly with deft strikes and prying movements (unlike the young bird in the photos). I agree, the youngster seems quite clever to have pushed the nut against a crack to hold it in place before aiming blows. As for the hammering sound. I suspect that was the beak coming into contact with the wooden fence. Incidentally, hammering on wood (knock, knock, knock) seems to be a behavior used in frustration or perhaps to signal a threat during aggressive encounter.

So here is the complete sequence from 18:47:53 Friday, July 13, 2018 to 18:49:39. All images copyright Robin Rowland 2018.

The steller’s jay is wrestling with the shelled peanut.

It seems to have done quite well demolishing the shell, in a gap against the old fence post. But apparently half the peanut shell was a hard nut to crack.

The steller’s jay takes a look….

 

I turned away for just a few seconds, and took a shot of the jays on the grass, with corn in their beaks. While shooting the jays on the grass I heard a “knock, knock, knock” sound, looked up and saw the steller’s jay working with its beak to crack that shell which was now anchored against the fence post.  Smart!

With the peanut shell firmly anchored against the wood and held tight in its feet, the steller’s jay repeatedly taps with its beak against the shell.

It keeps trying.  You can see part of the shell (or perhaps the peanut) on the beak.

 

A bee flies by…

… as the steller’s jay pauses for a second or two.

Finally success! It has the peanut out of the shell.

It enjoys its meal.

Looks like it’s finished because…


The steller’s jay discards the peanut shell.

 

 

And flies away.

 

A long shot of my fence taken the next morning.

 

A closer view of the area that the steller’s jay used to crack the nut.

 

And an even closer shot showing all the possibilities for an intelligent bird to anchor a peanut.

 

I just happened to look tonight (Monday July 16) and the steller’s jays were back at the rotten part of the fence.

This steller’s jay was back close to the spot where the peanut was cracked on Friday night.

 

No sign of peanuts tonight, so it was probably looking for bugs.

This is the tree where I’ve seen the steller’s jay living for the past eight years. You can see how BC Hydro contractors cleared a whole section of the tree to install new power lines that you can also see in the image.

The adventures of the stellar jay fledglings

 

Fledgling stellar jay

A stellar jay fledgling on the suet feeder on my desk. (Robin Rowland)

Early last Sunday morning I heard the thump of a bird hitting the glass door that leads out to my deck. I looked out and saw the bird stagger around the deck then take wing and land on the table on the deck. Birds do hit the door a few times a year and recover. So I went out as originally planned. (This photograph was taken later in the afternoon)

When I got back late in the afternoon…..

Stellar jay fledge

So when I returned, a stellar jay fledge was perched on the suet feeder. I stayed well back using my 300mm zoom lens.  For almost  20 minutes, the bird never moved. I was wondering it the bird was blind….

 

Stellar jay fledge

Then the fledge flew down to the deck and then hopped–not flying–down the steps. I came out on the deck, still keeping far away from the small bird. It looked at me, so clearly the fledge wasn’t blind, as it looked up.

Stellar fledge in the grass

The fledge then hops into the grass of my backyard.  It hops all across the yard to the back fence (not pictured) then suddenly flies over to the fence on the east side of my yard.

Two stellar jay fledges huddle at a fence,

There was the fledge’s sibling huddled against the fence.

Two stellar jay fledges

The two seemed to greet each other.

Stellar jay walks toward fence

 

A while later, one of the fledges, walks toward the north fence of my hard. It looks up.

Fledge tries to fly

The young fledge tries to fly, but doesn’t make it. And grabs on to the fence with its feet.

Two fledges walk.

So the pair walk toward the fence.

 

Fledge tries to fly

Again the fledge tries to fly over the fence.

Fledge walk under fence

So the pair walk through the bottom of the fence and disappear from my yard.


I was worried that the young birds, apparently still not able to fly that far, would fall victim to the cats that roam the park behind my house and sometimes come into my yard.

Then two days later, on Tuesday, on  my morning walk I came across what I am pretty sure is the same pair, about a kilometre from my house, in a gap in a cedar hedge.

Stellar jay fledge

Here’s what I believe is the most adventurous of the pair looking out at me from the hedge.

 

Fledgling stellar jay

 

Here’s the second one, a little further back in the hedge.

 

stellar jay fledglings

And the pair.

Haven’t seen them since, although I’ve been looking. I believe their parents are still around my yard, as a small resident family of stellar jays has been for years. So hopefully they’re either back with family or, since that hedge was close to the bush, they’ve found a new home in the forest.

Portrait of a stellar jay fledgling

For the second time this summer, a fledgling has taken refuge on my back deck and just stayed there.  A few weeks ago it was a young robin

On Monday, it was a fledgling stellar jay.

I had just got home and the young bird was sitting right under my feeder, not moving. the summer breezes rippling the downy feathers.

Unlike the more skittish robin, this fellow wasn’t moving at all, even after I stepped onto the deck with camera and Sigma  500mm zoom.

489-stellarfledge3.jpg

It was almost like taking a portrait of a human, except, in this case, the stellar jay was somewhat more cooperative. Still didn’t move. That’s how I got close enough for the two “portrait shots.” I backed off for a while.  The bird flew away, then came back for about another ten minutes. Then it was gone again.

Fledglings’ first flight

392-00404_fledgerobin.jpgSometimes the photos come to you.

Be prepared.  I have my Sony Alpha 850 with the Sigma 170-500mm on the dining room table to shoot the birds that come to my feeder.
It had been a slow week at the feeder

On Wednesday morning, a fledgling robin suddenly lands on my back deck, and not at all close to the feeder (which needed to be refilled anyway)

390-00371_fledgerobin.jpg

  
The fledgling robin didn’t appear to be that sure of itself, normally birds check out the feeder, fly away, come back, grab a meal, then fly away again. This fledge stayed put for at least 10 minutes….
….anxiously hopping up on one leg.
395-Untitled 4.jpg
Then a minute or so later,  the fledge turns and opens its mouth.
394-Untitled 3.jpg
Suddenly, and just out of focus range, one of the parents arrives with a worm for the fledge. The parent is gone again in an instant.
393-00420_parent.jpg

The fledgling robin still stays where it landed now about a dozen minutes earlier, probably still a bit unsure of itself.

 

396-00425_fledgerobin.jpg

Finally, safety and courage in numbers.  A sibling lands right beside the fledge. So it’s two  robins trying their first flights.
397-00445-fledgerobins.jpg

A few moments later, the fledged kids take flight into the cedar tree behind them as one of the resident stellar jays comes down to claim its territory and grab some seeds from the feeder.
