Several people answered Tuesday's teaser correctly — the two Green-winged Teal on the left are American Green-winged Teal, and the one with the racing stripe on the right is the Eurasian or Common Green-winged Teal, not common around here at all.

Congrats to all.

At our talk and slide show for the Hackensack River Kayak and Canoe Club last night, we included a few photos of Diamondback Terrapins, which are thriving along the lower Hackensack River.

Someone in the audience asked, "What do Diamondback Terrapins eat?"

We basically replied: "We're not sure, but we'll find out."

We asked NCMC Naturalist Brett Bragin, who responded: "They'll eat Fiddler Crabs, small Blue Crabs, fish, snails mussels and whatever else they can get, including vegetative matter."

After the talk, someone reported seeing a man taking turtles from the river near Mill Creek Point last week.

Taking turtles out of the river without the proper state wildlife collection permits is illegal. The turtles are apt to wind up in the illegal pet trade or in a New York City fish market.

If you see anyone taking turtles from the river, please take a photo, get their license plate if possible, and call NJMC staffer Jim Wright, who will pass the information along.

Don Torino of Bergen County Audubon Society, who co-leads so many of the Meadowlands Commission's free nature walks, has a new blog post about Mill Creek Marsh, where our next walk is on this Sunday, March 6.

The William D. McDowell Observatory in DeKorte Park begins a new month of programming tonight with free public access at  8 and 9 p.m. — weather permitting, of course. (Please note the later starting time.)

Dress for the weather; with the dome open, you are basically outside.

Each evening at least two major objects in the night sky will be viewed, plus one or two other celestial objects or events depending on the observing conditions.
