The year 2011 marked the dedication of a new riverside park in Carlstadt, lots of great nature sightings, and the continued partnership with Bergen County Audubon Society.

We thought we'd celebrate by looking back at 2011, month by month.

Here are some highlights from May:

May 3: Tri-colored Heron

May 6: Little Blue Heron at DeKorte
