What Happens After Hours?
Most animals end their day after the guests leave, hunkering down for a well-earned night of sleep.
But what about the zoo’s nocturnal species? We shed light on the zoo at night.

Animal planning at Lincoln Park Zoo reflects a species life in the wild. Amur tigers, for instance, are naturally suited for solitary lifestyles, coming together only to breed.

Where Does All the Poop Go?
Not all of the poop produced by the zoo’s animals gets pitched. Fecal samples are also repurposed
for hormonal analysis.

Special "looky loo" mirrors are among the items used to enrich Lincoln Park Zoo's great apes.

Do the Animals Get Bored?
For some species, napping the day away is entirely natural behavior…although new tools are
increasing insight into wild well-being.

I'm wondering if the wild Canada Geese outside or inside the zoo 1) are once again not migrating, and 2) if not, are some freezing to death? Is the population likely to be a lot smaller next summer?

Great question--we'll ask our experts at the zoo's Urban Wildlife Institute.

Coordinator of Wildlife Management Mason Fidino responds:

"Interesting question! Many individuals of a species, Canada geese included, will not migrate if there are sufficient resources (i.e. food) to overcome the negative effects of winter (e.g. the energetic cost of staying warm in freezing temperatures).  This strategy is often called "bet hedging." The goose is decreasing its temporal variance in its fitness, and by doing so accepts an overall decrease in fitness

So what's that mean to the goose? No doubt a goose in Florida has a lower energetic cost than our Illinois goose, but it had to fly all the way down there in order to gain those benefits. By making the decision to not migrate, the goose is accepting the fact that it will be cold in the hopes that the energy spent staying warm will be less than the cost of migrating.

It's a roll of the dice, and often it pays off. A bird that does not migrate is already where it needs to be and can lock down prime nesting habitat way before any of the other migratory birds arrive. However, with the close-to-constant snow cover and dips into sub-freezing temperatures the bet many geese made did not pay off.  Some of them may have died, others may have headed south in hopes of finding a warmer climate.

On the whole though, I would not expect this to heavily impact the goose population. We often see geese year round, but many of them still migrate and will be showing up in the spring. When I helped the Chicago Audobon society for their Christmas bird count in December, all the groups collectively counted more than 10,000 Canada geese migrating!"
