Bear Patiently - Lincoln Park Zoo Poem by Ima Ryma

Sometimes the polar bear, Siku,
Needs to have a blood sample drawn
Here at home in Lincoln Park Zoo.
So Siku has been called upon
To give blood voluntarily.
Keepers trained him to reassure,
And thus he does not need to be
Put under for the procedure.
Siku extends his paw so that
Blood can be drawn and without stress
On Siku in his habitat.
Siku's a patient patient - yes!

And keeping Siku happyish -
During the draw a lot of fish.
