Spring, a time for eggs hidden in planters

Spring, a time of year symbolized by eggs.  Birds of all sorts busily build nests, lay eggs and incubate as soon as they can to maximize the growth of their family before they migrate.

Canada Geese stake out nesting sites during this time, and their fearless demeanor make them fairly comfortable nesting in manmade structures such as planters or parking lot islands.





At our office, a goose selected a planter outside one of our windows as a safe place to create a nest and lay eggs.  It is definitely safe, since it's on the fourth floor.  But...well, it's on the the fourth floor.  We consulted Wildlife Rescue, who told us that geese do survive four storey drops, but it would in fact be the glass barrier that would prevent them from getting to ground level.  They recommended we wait until the eggs hatch, (28 days after being laid) at which time they'd send someone to move the family.

So now, we knew that we'd have a closeup view of the goose for close to a month.  The nest was right outside one of our windows, and our IT team set up a webcam to enable viewing by our staff.

The goose laid her first egg March 27, but she'd disappear for a day before coming back and laying another.  While she was away, she'd obscure the eggs with debris, but the next morning, we'd observe another egg laid.  She repeated this until she laid her fifth egg, on April 3, at which time she started incubating. We thought this would be it, but we counted a sixth egg soonafter.  Many birds will lay their eggs one at a time, and only start incubating once the last has been laid to increase chances the chicks will hatch at roughly the same time.

On May 1, exactly 28 days after incubation began, all six eggs hatched.



Wildlife Rescue came by the same afternoon, and relocated the family to Deer Lake in Burnaby.

During the last month, we saw the gander only a handful of times, and in the final couple of weeks, we didn't see him at all.  We did see a lone goose sitting in the grass at ground level, but we couldn't tell whether he was the gander for this mother, or for some other family (there were at least a couple other goose families around in our building complex).  Wildlife Rescue doubted he was it, as they should be communicating a lot more frequently.

Wildlife Rescue said that this is a very busy time for geese. Downtown Vancouver is especially busy, since there are few roofs there that provide safe ways for goslings to get to ground level.

Since we had ample footage, I put together a video with all the action. There's a 2 minute and 10 minute version, depending on how much of a goose fan you are.  The 10 minute version has a lot more footage of the rescue operation.
