I walk around the neighbourhood several times a day during nesting season, checking in on the crow news — taking photos and making mental notes of how things are with the various crow families I’ve become acquainted with over the years.

At this point I’ve got so many crow-notes stuffed into my head, I’m not sure where to start unpacking them.

Rather than trying to cram all the news into one post, I think I’ll go one crow family at a time, starting with the Pants family in the next post.

First though, I have to tell you about this morning’s drama.

We’ve had nesting bald eagles in the neighbourhood for years, so all through each nesting season the eagle parents scour the area for baby eagle food, always followed by a loud and angry crow posse. This morning I happened to catch some of the action from relatively close quarters when the eagle landed in the school grounds at the end of the block.

The crows, backed up by screeching gulls, seemed even more loud and frantic than usual.

So impassioned, in fact, you can see one crow in the video below whacking the sitting eagle hard enough to cause it to fly off.

The reason they were so mad? It looked as if the eagle had scooped an entire crow’s nest right out of a tree. You can see a glimpse of the nest in the video below.

In the end, the eagle dropped most of the nest, although there was something still gripped in its claws as it flew off.

The eagle population is part of the reason the crows are changing their nesting habits.

Local ornithology expert, Rob Butler, who spoke about crows last weekend on local CBC Radio show, North by Northwest, mentioned this change: crows who had previously chosen high nest sites for protection against ground based predators (raccoons, cats, coyotes) are now picking spots in lower, less eagle-accessible trees — even selecting quite small street trees they calculate will be awkward for raccoons to scale.

I’ve certainly noticed that our local crows have rejected the once-coveted penthouse suites in the Notre Dame poplars this year in favour of much lower and more camouflaged trees. Marvin and Mavis have picked such a low, mid-street location for the nest this year, it would be quite the drama if the eagle swooped that low.

If you think being dive-bombed by a crow is exciting …!

The Pants crow family, who I’ll be looking at next time, have long been fans of the low-rise nest building solution and we’ll have a look at what they’re up to this spring.

Marvin and Mavis Nesting 2020

May 14, 2020 / The Urban Nature Enthusiast / 9 Comments

I know I haven’t written about my crow neighbours for quite a while. There are a couple of reasons, apart from the distraction of Edgar and the Cabin Fever series.

One: I have just SO MANY images and stories filling up my brain and computer, I’m having a hard time knowing where to start. But, since it’s also time to start thinking about the 2021 City Crow Calendar, it’s time for a dive into Crowlandia.

Two: it is nesting season, which fills me with a certain level of anxiety. Like most of us, I already have a bit of an anxiety surfeit, so I was trying to keep a slight emotional distance from the rough and tumble of the bird reproductive season.

But I know it’s hopeless, I can’t stop myself from getting invested in the drama.

I’ll start with a bit of an account of Marvin and Mavis’s nesting season so far. I worry especially about these two as they are my regular visitors and, over the past years, I’ve seen them lose three seasons’ worth of fledglings — to racoons, falling-out-of-tree mishaps and bald eagles.

Marvin and Mavis’s nest, May 2019

For the last two springs, they built their nests high in the Notre Dame poplars.

While those trees have the advantage of height and protection from ground predators, they are also a favourite buffet for the local eagles and hawks. All of the local crows seem to have come to the same conclusion, as I haven’t seen any of them building nests there this spring, although they’re still popular with smaller birds.

Marvin and Mavis got an early start on this year’s nest building back in March, choosing a nice dense pine tree. I’m not sure what went wrong with that project, but by April they were real estate shopping again.

They turned their attention to the dark red-leaved plum trees on our street, which offer great camouflage for dark coloured birds. A couple of problems arose there.

First of all, Mabel and her mate got an earlier start, with their substantial nest all finished in another plum tree weeks ago. With the added advantage of two youngsters born last year hanging around as nest helpers, they’ve been able to wage war on Marvin and Mavis whenever they start a new building project.

Marvin and Mavis persevered, however, and managed to start a nice looking nest in one plum tree at the far end of the block from Mabel and co.

While it’s wonderful that many people, forced by the pandemic to slow down and stay close to home, have started appreciating their bird neighbours in a new way, it’s also true that it’s given people more time to become very particular about their gardens. Unfortunately for our intrepid couple, the humans whose house they were building in front of decided they did not want to experience the thrill of a crow’s nest so close to them, and started to knock the partly built nest out of the tree. I did try my best friendly Crow Evangelist pitch to get them to leave it alone, and I thought I’d made some progress, but by the next day the nest that Marvin and Mavis had started rebuilding was gone again, so I guess not.

Having read the writing on the wall, M & M selected another plum tree. This is where they are now — trying to be very quiet as it’s rather too close for comfort to Mabel’s nest. Luckily, all of the crows now seem to have entered the “witness protection” phase of the nesting season where they’re all just trying to be invisible from any potential predators.

Fingers crossed for them this year. I don’t think they have eggs in there yet as both of them have been coming to the house to visit several times a day — for pep talks and some peanuts.

I’m trying not to draw too much attention to their nest as they try to keep a low profile, and hoping that things go well from now on. Fingers crossed for some little Marvins and Mavises this year, even as I try not to get my nerves too jangled at every twist and turn of the nesting tale. I’ll keep you posted …

In our local Crowlandia we’re ricocheting between serenity and stress.

Suspense is the name of the game as eggs and hatchlings start to fill the nests.

Most days it’s seems really very peaceful. The crows maintain an uncharacteristic hush behind leafy screens, quietly guarding their nests.

In April, it was possible to see a pair of crows constructing, and then sitting on, a nest high in the poplars from the comfort of my dining room window …

A couple of weeks later and the nest is discreetly hidden by foliage.

I’m pretty sure that this nest belongs to the Firehall Family of crows.

One day earlier this week both of the nesters made a rare double trip down to terra firma for a chat.

Perhaps they were out on a date, although one of them seemed to be feeling the need for a little personal space ….

Eric and Clara are around too. I think their nest is also in the poplars, just a bit to the south of the Firehall nest. It’s not within view of my window and too far up to see from the ground, but Eric is guarding his corner diligently.

A couple of weeks ago there were a few inter-crow skirmishes between Eric and the Firehall gang, presumable sparked by minor breaches of neighbourly conduct.

A detente seems to have been reached lately.

A circumspect hush has fallen over the neighbourhood.

Now that nests are becoming populated, location is an even more closely guarded secret. Energy must be saved for the most important things.

Part of the silence seems due to the absence of some of usual crow enemies at the moment.

The ravens have moved on. I haven’t seen or heard one near here for almost a month now. Also missing: the pair of bald eagles that usually cruise the area at this time of year. Perhaps both ravens and eagles are waiting to hear the quacking of baby crows before they start their “grocery shopping” expeditions.

But there is one sure thing around now that will get the nesting crows to break their silence.

With a vengeance.

Meeting of CCC (Concerned Corvid Citizens) in the alley earlier this week.

Two weeks ago Marvin cawed for an entire day. He was cawing when I got up, before 6am, and he was still at it when dusk fell. Even by crow standards, he was sounding a bit hoarse by then.

The culprit, in both of these incidents, was almost certainly the masked bandit. The tree in which Marvin and Mavis seem to have their nest has been robbed by racoons every spring since I’ve been noticing such things.

Yesterday, on the dog walk, I heard a furious crow, then noticed a small, lollipop-shaped tree in someone’s garden shaking as if in a hurricane.

As it was a windless morning I decided to wait and see what happened next.

Sure enough …

I’m not sure if the raccoon scored any eggs this time. Perhaps Geordie and I interrupted this particular heist, but those clever little hands are very adept at nest robbing. I suppose there are little raccoon kits waiting for lunch somewhere.

Circle of life, and etc …

Marvin and his trusty pal, Rusty, engage in philosophical discussion on the back gate.

Marvin is still coming by occasionally for a snack and visit. I imagine Mavis is on the nest, so I’m hoping Marvin is thoughtfully saving some peanuts to take back for her.

On a recent dog walk I heard a crow begging call coming form a cedar tree. It sounded just like a baby crow calling for “food, food, food” — but it’s too early for such noisy youngsters. As I suspected, it was a mother crow, confined to nest duty, calling out to dad to quit lolling about, pondering the meaning of life, and *@#*%! bring her something to eat.
