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 April:

April 1: Really Unusual Blackbird

April 4: Wilson's Snipe!

April 21: Of Ospreys and Earth Day

April 28: Red-necked Phalarope at DeKorte

April 30: Virginia Rail at DeKorte
