Social media caw-gratulations are pouring in as Canuck the Crow tends to a nest full of new hatchlings.

The famous East Vancouver crow and his mate Cassiar have been busy feeding their chicks since they hatched late last week.

Shawn Bergman, who chronicles the bird's life on social media, estimates there are probably three chicks chirping in the nest.

He noticed a difference in Canuck’s behaviour last week; the crow didn’t visit as often and was spending more time in his nest.

“It was basically putting two and two together that there's now babies in the nest,” said Bergman.

More than 100,000 people follow Canuck's exploits on Facebook, and Friday's announcement drew a flood of celebratory comments.

"Congratulations to the beautiful family," one wrote.

"I'm keeping my fingers and eyes crossed that this time there is a happy ending," said another.

Sadly, the crows' previous two attempts to raise chicks were unsuccessful. The latest batch was killed by an airborne predator in early May, according to Bergman.

But the last nest was built before the leaves started coming in and ended up having little coverage, which made it vulnerable to attacks. By contrast, Bergman said the new nest is "virtually invisible from all sides."

Canuck is very, very focused,” Bergman told CTV News Vancouver. “It's all about the kids, it's all about getting food, washing the food, taking food up to the nest and then back to getting more food.”

The day after the announcement, he captured what he described as a "tender moment" between Canuck and Cassiar as they took a brief break from parenting.

"They landed, hung out for less than a minute, then Cassiar was gone back to the nest," Bergman wrote. "This was the first time I've seen the two of them away from the nest at the same time since feedings began."

Canuck first captured the public's attention by stealing a knife from a Vancouver crime scene. He was later "employed" at the PNE Fair, with his wages going to an animal shelter.

Bergman and the crow were also the subject of a short documentary, "Canuck and I," back in 2017.
