Well, the bald eagle was nearly wiped out from DDT , so that's why. Turkeys I think the state stocked(as they did with canada geese) to sell more licenses. Coyotes are very secretive, but have been spreading farther into the range they once had. Bears have always been in NJ , but had more room to be left alone. They didn't have any real enemies(besides cars) , so they grew in numbers(to 1/2 what the state claims). developing has made them more noticable. If you go to Stokes, high point , waywayanda, pequannock watershed you have a good chance at seeing a mother with her cubs where they belong. I drive from the delaware watergap to high point through state land mostly and down to pequannock in a day of birding. I may see a bear if I am lucky.

Ruffed grouse are VERY SECRETIVE and desire alot of woodland. I know where 1 pair is in this state.... ONE!!!

Deer are a product of developing, you can't hunt them near homes! The state made a mistake by stopping people from shooting so many males IMHO. I think you should be able to kill as many deer as you want for a few years, but after every buck you need to kill a doe ;)
