Happy Bears – UPDATE July 13, 2013

20130713 Junes female cub gooseberriesJune and female cub eat gooseberriesIf food makes bears happy, they should be happy now.  People with feeders are wondering where all the bears are.  Jim Stroner went out this morning to see what June and her cubs were up to.  They were in a clear-cut mostly tearing open stumps and logs for ant pupae.  June dug out an underground bumblebee nest (probably Bombus ternarius), shaking her head frequently with hardly a pause in her digging.

This is one of the best food years we have seen.  The bears are showing how much they prefer the wild foods, especially the ant pupae.  June eats blueberriesJune eats blueberriesThe bears are showing that it is not habituation and food conditioning that drive them to feeding stations, it’s hunger.  What bears do and what they eat depends upon what the alternatives are, and the preferred alternative at this moment is the variety of wild foods.

Thank you again for all you are doing to help the bears and keep our research alive.  As we’ve said before, we’re hoping for fairness, an injunction, and an investigation.  The support you show for the research is helpful.

Thank you for all you do.
