The first of the young mink in Maria‘s feeding height experiment had their first preference test on Friday.  Given food on all four feeding levels at once, which would they chose to eat from?

DSCN5048Behaviourally we couldn’t quite tell — scan sampling proved inadequate for picking up the brief upward bobs (think Whac-a-Mole) they make when taking bites of food, and so Friday and Saturday were spent rapidly refining and re-refining this protocol.

But in terms of leftovers the next morning, the lowest height was the clearly preferred (e.g. below, left to right, you can see what’s left from the previous day’s food on levels that are respectively 10, 18, 21 and 15 inches above the cage floor): so far, it seem these young mink would rather not climb for their dinner….

Over the next few weeks and months we’ll see if this holds, and whether it changes as they get bigger and stronger.
