Ravens have the ability to recognize old friends, a new study reports. And just like humans, they react negatively when seeing a foe. [continue]

I’m convinced they think Dog is a foe. (And they’re right. She holds grudges and remembers that Raven stole her dinner.) I’m also convinced that they tease and mock her, which is not very sporting of them.

Fire Chief Rick Jackson said he had been considering getting the site cleaned up sooner, but there are currently birds using the piles of debris for nesting. Come June, once the nestlings are flying, then work can begin.

I’m sure Leigh Ann Milman (of the Gabriola Land Conservancy) will be pleased. Did you see Leigh Ann’s note in the paper a while ago? If not, go read a small request over at Pericat‘s site.

Have you been down to watch it all? Cheryl has, and she sent us this photo:

Isn’t that stunning? This is even better: a close-up of the sea lions in that photo:

Thank you so much, Cheryl, for sharing this with us. Your photos are a gift.

It’s well known that birds, such as the European Robin, can detect the Earth’s magnetic field in order to help them navigate on long migratory flights.

This ‘compass’ sense must be associated with the eyeball, because the birds cannot detect magnetic fields in darkness.

But now Oxford University and National University of Singapore scientists have shown that birds may really ‘see’ the invisible force of magnetism, giving them a compass on top of their normal vision: rather like aircraft ‘head up displays’ which overlay crucial navigation information on a transparent screen in front of the pilot.

(And do you think I can find the article now? No, I can’t. Though this is awfully interesting.)

Anyway. Every time I fail at taking some photo I want, I think bring on that new technology! Because clearly I need more help. Earlier this week I was in the forest with Dog, and we were stalked by this bird for 20 minutes or so. And, as you can see, I almost got a photo of Bird in Flight, but not quite. Argh.

So What do you suppose it is? My guess is: immature eagle, or turkey vulture. What do you think?

(And yes, this is the bird that some of you noticed in the How to get enough vitamin D on Gabriola post.)

Update, February 21st:

Though seen in a different part of the forest, I think this is the same kind of bird.

I have been surprised by the dozens of robins all around our place at the south end. I’d be curious to hear the birders explain their sudden appearance in great numbers. Does this mean spring is really on the way?

What do you think, Gabriola birders?

For two years, Simone Pika und Thomas Bugnyar investigated the non-vocal behaviour of individually marked members of a wild raven community in the Cumberland Wildpark in Grünau, Austria. They observed that ravens use their beaks similar to hands to show and offer objects such as moss, stones and twigs. These distinct gestures were predominantly aimed at partners of the opposite sex and resulted in frequent orientation of recipients to the object and the signallers. Subsequently, the ravens interacted with each other, for example, by example billing or joint manipulation of the object.

Ravens are songbirds belonging to the corvid family like crows and magpies, and they surpass most of the other avian species in terms of intelligence. Their scores on various intelligence tests are similarly high than those of great apes. Ravens in particular can be characterized by complex intra-pair communication, relatively long-time periods to form bonds and a relatively high degree of cooperation between partners.

Slow-motion footage has revealed how a hovering hummingbird is able to cope with wet weather.

The cameras show that the delicate bird shakes its head with such acceleration that it can reach a g-force of 34 (Formula 1 racing cars typically reach less than 6g).

This mid-air manoeuvre takes just 0.1 seconds and removes almost all of the water droplets from its feathers. [continue]

How cool is that? Considering the amount of rain we get on Gabriola, we must have hummingbirds doin’ this crazy shake quite a bit.

Residents complain that the turkeys eat their shrubs and garden vegetables, frighten small children and snatch cookies out of their hands, wake families up before sunrise and cross the streets in indolent flocks that seem impervious to impatient drivers. [continue]

The nerve!

Now, by the way: are there any laws that would prohibit the catching and eating of wild turkeys on Gabriola? Sheila M’s comment about the bunnies has me wondering.

(From Gabriolan.ca.)

Wow.

(Dear photographer: last I heard, you didn’t want a photo credit. Please advise if you’ve changed your mind.)

(From Gabriolan.ca.)

If you’ve ever watched and heard them peck (or listened from your bed as they attack your metal chimney at 6 am), you might wonder how they manage to do all that pecking without addling their brains.

Meanwhile, Gabriola Bird Blog‘s Owl comes home to Gabriola post tells the story of an injured barred owl who was rescued on Gabriola, bundled off for rehabilitation, and returned to the island. The story makes a good read and the owl-in-flight photo is wonderful.

Meawhile, we are owl-less. Sigh.

Thank you so much, Elen. This is fantastic!

The compost is under a cedar tree at the back of the property. Low branches stretch out over the compost.

This evening I noticed an owl perched on one of those branches. Owl spent at least an hour staring down into the compost — waiting for dinner to arrive, I suppose.

I am quite pleased about this. I like owls.

Thursday July 7th update: owl is back, staring down into compost again. I hope this will (or has?) become a nightly ritual. Anyway. Got photo! I suspect this is a barred owl.

(From Gabriolan.ca.)

What do you think? Is this a normal juvenile hummingbird, having a snooze? Or is it a dead hummingbird? That porcupine-like appearance is a bit strange.

I’d like to know more about the birds on Gabriola, but I’m usually too tired to do the research to find out about them. But if somebody who knows is willing to present the info to me on a blog-plated platter, that is a Very Good thing.

Anyway. Here is more annoyed wildlife news: Angry Velociraptor Crows Terrorize Everett Police:

Collectively, a group of crows is known as a murder, and murder is apparently exactly what this particular flock has in mind. One lieutenant described how he got zinged by the birds and proclaimed that the force’s new airborne adversaries are like velociraptors. Even more troubling, the evil avians are reportedly targeting top brass and detectives in particular.

Of course, Everett’s finest aren’t ones to give up without a fight. One officer sounded his siren at the crows, hoping to scare them away. But alas, his police cruiser was promptly carpet-bombed with bird poop. [continue]

At the moment, the island’s turkeys are even more than usually interesting. Some of them are lurking near the bottom of the s-curve on North Road at Horseshoe, between the mailboxes and the Old A-Frame restaurant at Barrett. They hide amongst the bushes, peck things, cross the street, and hide amongst the bushes again.

But this time they have little baby turkeys with them. The chicks are adorable; take a look and see if you can spot any next time you pass.

Here’s a larger, zoomed-in view of the bird’s head, just because:

Well, ok, it’s because no other Gabriola bird has ever sat still to have his photo taken, and this one did.

Is that not a fine pattern of plumage there? ‘Tis a distinguished backside. I bet your hind quarters aren’t as well patterned nor as well feathered, which is probably a good thing.

American Scientist’s Flights of Fancy article explains:

The graceful aerial displays of starlings and other flocking birds have long inspired admiration and wonder. Lately they have also inspired serious work in mathematics, computer science, physics and biology. A theoretical framework for explaining the behavior of tightly clustered flocks emerged in the 1980s. The key idea, which came from computer simulations, is that purely local interactions between nearby birds are enough to hold the group together. Similar mechanisms are thought to operate in schools of fish, herds of grazing animals, swarms of insects and even crowds of people.

More recent work builds on this foundation. In particular, an ambitious program of stereoscopic photography and digital image processing has made it possible to reconstruct the positions and velocities of individual birds within large flocks. The new data suggest some refinements to the algorithms that are thought to govern the birds’ movements. The three-dimensional reconstructions have also brought some surprises about the overall shape and structure of the flocks, and show that the birds’ movements are even more delicately coordinated than casual observation would suggest.
