Bergen County Audubon Society is sponsoring a walk at storm-damaged Losen Slote Park in Little Ferry on Sunday from 10 a.m. to noon. Birds of interest are for winter migrants, raptors and whatever else shows up. Wear waterproof boots — the trails can be muddy. To rsvp, contact Don Torino of the BCAS at greatauk4@aol.com or 201-230-4983.
