Corvid Flash Mobs

Somewhere between harvest festivals and soccer riots, these autumnal corvid gatherings are a sure sign of the seasonal shift.

Crow Crowd

A quiet street corner that is normally the domain of a one crow family is suddenly full of noise and dark feathers. It’s usually early evening when they come, making a stop on the longer trip to the nightly roost.

crow crowd on wires

Wires that are normally punctuated by only two or three crow silhouettes are suddenly sagging under the weight of dozens.

And it’s loud. Not, I grant you, as spectacularly cacophonous as the Still Creek roost — but enough to make itself heard over the indoor household noises.

Enough to make you put on a jacket and go outside to see what’s up.

Often there are additional sounds among the cawing. Crack, plop, bang.

Like giant hail, nuts are falling from above.

 

 

In our neighbourhood, two hazel and one walnut tree produce their bounty at about the same time. It seems that the crows of Vancouver have those dates indelibly written in their mental calendars, because every late September/early October (and I’ve been watching for several years now) they come.

The crows leave many nuts on the roads so that cars can do the heavy nut cracking work for them. Because it’s not a very busy street, they entertain themselves between vehicles by dropping the nuts themselves. This seems to have little effect, but they do look as if they’re having fun.

And it’s not only the crows that have this time of year noted in their “things to do” list. Squirrels are darting about amongst the crows, determined to get their share of the seasonal windfall.

Last year (alas, I did not have my camera) there was a human vying for his portion of the nut harvest. Clearly he knew what he was up against as he headed out for his task wearing a bicycle helmet.

I managed to harvest these two, without a bicycle helmet.

The nuts are the focus of all this celebration, but it really feels as if more is going on.

There’s a real party atmosphere when they gather in these loud unruly groups.

The long, hot, dry summer is finally over. Life is easier now. There are puddles to splash in, and worms to dig out of the dirt again.

Crows that have been busy — first nesting — and then trying to keep fledglings alive —since early spring, finally have some time to themselves. The young ones are big enough to forage for themselves and join in the harvest festival fun.

Another reason for celebration — the endless molting season is nearing an end. Crazy bald-patch zombie crows are starting to revert to their true sleek selves and that has got to feel really good.

Baby crows that have survived their first couple of months are now able to fly to the roost every night so the big nightly party is back on. These “block parties” are just the warm up to the main event at Still Creek.

Getting in tune for the roost later on.

Just as the sun goes down a crow somewhere in the mob sounds the signal.

The wires erupt into a clatter of shadowy wings and commentary.

Then suddenly they’re gone. All of them.

The wires are vacant and the nut-strewn street is silent.

Golden Poplars and Crows

A small tributary of crows trickles through the stand of poplars, golden in the last light of the day.

Crow Murder (Attempted)

In contrast to the rather peaceful imagery of Crow Calligraphy, where corvid nesting behaviour evoked the peaceful strokes of Japanese brush painting — this post is more Sam Peckinpah meets Hieronymus Bosch.

I usually don’t like the term “murder” to describe a group of crows.

Rather prejudicial, I always think. In the case of this gathering, however,  it seemed apt.

Incredibly, (spoiler alert) all participants in this brawl did walk away — but the ferocity was something I’d never seen in my all years of crow-watching.

The crows are pretty fractious at this time of year. All of that bucolic nest building has the side effect of making them hyper-sensitive to territorial infringements, — by traditional foes (raven, eagle, cat,  racoon, coyote) — or their fellow crows.

On Sunday morning the crows were particularly loud. I assumed it was the usual group protest directed at the new raven in the neighbourhood.

Crows in the Poplars

I was first preoccupied with the raven, who seemed especially oblivious to the crows on this particular morning . She carefully ran through a full repertoire of calls and meticulously groomed her lovely feathers.

The crows weren’t bothering to swoop and harass her, and I noticed that their anger seemed focussed elsewhere. I walked over that way to see what was bothering them.

Just then, all hell broke loose. From a distance, it looked like a muscular black feather duster exploding in the middle of the alley way.

As I got closer the individual participants in the melée became more distinct.

Crow Fight 1

It seems that two or three crows are at the centre of the brawl, with one of them pinned to the ground.

Crow Fight 2

The fighters are surrounded by a vociferous crowd — like a scene from Gladiator, with some Hogarthian figures passing judgement from the sidelines.

Crow Fight 5

Crow Fight 6

Just as I was thinking that this fight might need a human referee, a corvid one seemed to step in. Abruptly the flapping stopped and “discussion” resumed..

Crow Fight Mediator

Miraculously, the combatants, aside from some ruffled feathers, looked relatively unscathed.

Indignant, but uninjured.

Crow Fight 9

The warring factions decide to suspend hostilities, and live to fight (and nest) another day.

Crow Fight 8

Of course, someone always has to have the last word …

Crow Fight Aftermath

The crowd dispersed as far as the nearest trees and wires where they continued to comment on the event for quite a while.

Political panel

Political panel “unpacks” the issues.

Eventually the tribunal concluded and all participants went back to their own territories. There they resumed the more tranquil business of finding just the right twig to complete the perfect nest.
