Oxygen and CO2 can pass through the shell. I learned this recently when hearing that one method for controlling the Canadian goose population where I live is to find the nests, distract the parents, and paint the eggs with a thin coat of cooking oil, which blocks the o2 in, co2 out process. The adults don't notice and continue caring for the eggs but they simply never hatch.

That's like next level infanticide. Smother ... let the geese keep their growing excitement for parenting.... then watch the geese be sad. What's good for the gander isn't always good for the goose.

Geese do not have a growing excitement for parenthood. They act on instinct

Have you asked a mother goose?

A survey of geese on the excitement they feel for parenting showed the following:

70% responded "squawk"

30% responded with pecking

And what is "growing excitement" if not an instinct ;-) ?


herrbdog t1_iu1vexi wrote

with few predators, they quickly become a nuisance

yeah, humans are to blame for that

at least we should eat them like the wolves and coyotes would have

And the reason they do it this way is because if you remove the eggs they just lay more.

The same things works for pigeons by the way. You get them to lay in a special nest where you simply make sure they don't hatch.

Though in this example they simply shake the eggs, which is apparently enough to prevent them hatching.

I'm so tired... Am I supposed to... shake the baby?

You don't have to follow the recipe - your favorite undetectable baby killing method works too

This works with most birds apparently. Take the eggs away, they lay more.

It's really helped bring back the falcons in NY.
