North-American Porcupine

The second largest rodent after the beaver. Dark-brown in color with white highlights. Slow moving and defends with exposing quills after warning with a strong odor. Lives in coniferous and mixed forested areas, feeding mostly twigs, roots and berries in summer and needles and bark in winter.

How to Identify?

Color and shape. They don't flee if detected. Don't get too close unless you want to expose yourself to the odor and quills.

We combine physical characterics and behavior patterns with location and seasonal aspects to identify species.

Where & When to Spot?

My only observation of this species happened in a forested area near Tadoussac in May.

With each photo, we store date and geo-location providing us data about location and season of observation. We also use a tracking utility to save observations in the field when there was no opportunity to take a good shot.

Anything to add, to correct?
