Welcome to the first in a series of Tuesday Teaser’s devoted to Losen Slote Creek Park, the site of our fifth annual Super Bird Sunday Walk on Feb. 2.

Between now and then, we will offer a different Losen Slote-based Teaser presented by the Bergen County Audubon Society. To participate, just e-mail your answer to the Teaser each week to Jim Wright at jim.wright@njmeadowlands.gov by each Tuesday at midnight, with “Teaser” marked in the subject field. The person with the highest number of correct answers will win a prize of note.

Today’s Teaser is pictured above. What is it?
