Hi I've had a little look around and I think if you are referring to the Nikon range of lenses then they probably are very similar to the Canon ones and the simple answer is yes.
However, it does also depend upon what you want to photograph. If the subject is likely to fly away when approached then obviously a longer focal length lens would be appropriate but if you can get very close without losing the shot then the smaller focal length would do just as well.
I find that I can get very close with my 100mm lens but even then I have to approach very slowly if I am to be successful.
Hope this helps, it's a difficult decision but in the end I found that the more expensive option was actually the best
