Right out the bathroom window ! They don't shy away from neighborhoods Nessie - Indeed! This is a photo a friend of mine took in California of a fisher dumpster diving.

Jack: what is the biological reasoning behind the lack of a saggital crest in the females ? I assume the muscle attachment points are the same in both sexes .....NO ? I have absolutely no idea, Ken. The sagittal crest is for masseter muscle attachment, and the males have a much expanded list of prey items (over the females). Obviously they eat much larger prey (on the average). Could it also be that the female picks a birthing den that she can barely fit through, in an attempt to keep males from entering and killing the neonates? These are the only possibilities that come to mind. Let me think on that question a bit... Jack

Also, I wonder whether the males make greater use of bones than the females do ?? Thus develop those masseters more than the girls do and the crest along with it What about this........can you tell a male from a female YOY by the skull suture ??

That's interesting Bruce. Can you point me to the data on that predation and how it was collected ? Thanks ! The data on Fisher killing marten was from me trapping Fisher and marten on my own trap lines for years seeing where Fisher ate marten from my traps confirmed by evidence in the snow(tracks,ect.).Most times I would then catch the Fisher on my next trap visit.I have also seen Fisher chasing marten. OK thanks. So just a target of opportunity rather than actual predation.

I found no differences between the sexes in timing of suture closure. Obviously, the sutures (especially the nasals) are not cemented in the YOY age class, but it was the same for both sexes. Just based on total length and/or zygomatic width though, you could separate sexes. Jack

Young-of-the-year animals can be determined by the growth plate (the hypophyseal/epiphyseal symphysis). Juvenile on the right, adult with fused bone on the left. I like this post Gulo! What bone is this in the picture?

The female must "know" that relationship inherently/instinctively. Can you determine sex ratios of previous litters from placental scars .....or are the neos just about the same size at birth ?

No variation that I can detect in size of placental scars. [quote=Jurassic Park][quote=Gulo] Young-of-the-year animals can be determined by the growth plate.

Easiest furbearer to catch in my opinion.
Seem fearless and always cruising.
Neat animal.
swampgas chili and schmidt beer makes for a deadly combo
