Table 3. Mortality sources of 65 Canada lynx in northern Maine, USA, 1999 and 2011. Mortality source n Predation by fisher 14 Predation by unknown predator 2 Likely predation by fisher 2 Starvation 17 Undetermined 17 Legal harvest in Canada 7 Illegal harvest 3 Vehicle collision 2 Disease (hyperthyroidism) 1
The illegal harvest were two shot in traps & on found (with tracking collar) behind a couch in someone's living room, if I remember correctly.

Maybe a kitten or a starving lynx would be vulnerable. A big adult lynx-no way a fisher would find that a desireable target among other plentiful targets that would be way easier.The speed at which a lynx can cover ground when attacking is unmatched.Their long large back legs are like springs.I have seen lynx cross a hiway in one bound from shoulder to center to shoulder faster than I can say it.In winter the poor fisher would be at such a disadvantage it would be no contest. The fisher would be slashed to ribbons.

It is unlikely that fishers killed lynx in Maine as a result of a specific, learned behavior by 1 or 2 individuals, nor as a result of preying upon weaker individuals. Instead, the spatial and temporal distributions of lynx mortalities (Fig. 2) encompassed the territories of multiple radio-collared fishers over a 12-year period (MDIFW, unpublished data), suggesting that fishers were opportunistic predators of lynx. In addition, during the first 8 years of the study when snowshoe hare densities were >1 hare/ha, only female lynx were killed by fishers, possibly because of their smaller body size. However, when hare densities declined to <1 hare/ha, more lynx were killed (64%) and both male and female lynx were killed, suggesting that fishers were opportunistically killing what they encountered (Golightly et al. 2006). Although fishers are not as well adapted as lynx in environments with deep snow because of their shorter legs, they are better adapted to these conditions than other predators in the region that have a higher foot-load (e.g., coyotes; Krohn et al. 2004). The absence of other known predators of lynx (e.g., wolverines, mountain lions, wolves) in northern Maine, along with favorable habitat conditions, may have created a unique opportunity for fishers. Although fishers are smaller and weigh less than lynx (x¼4.6 kg, n¼20; MDIFW, unpublished data), they are aggressive predators, which under the right circumstances can give them an advantage over lynx. Despite the size difference, our data show that fishers are capable of selecting a more profitable prey item in winter (Type III functional response), but there was no information to demonstrate that fishers are competitively excluding lynx from habitats, or are limiting the range or number of lynx in Maine.

The guy that wrote that is an idiot. Every trapper in Lynx country knows that the major predator of lynx is other lynx.In fact the only major predator. Wolves will take the odd one if they can catch one in the open which is very rare. I would say with confidence that any lynx that were scavenged by fisher were killed by other lynx at the low end of the hare cycle.

The very worst thing that has EVER happened to the Maine trapper is when that f---ing Lynx moved over the line. That very movement has ended true long line fisher and marten trapping in Maine, as well badly hampered canine and actually any other trapping.

If he doesn't know that the main predator of lynx is other lynx then he is "uneducated" or has an agenda.

Hey Boco, bottom line. They trapped 187 lynx, equipped 85 with radio-collars, and investigated mortalities when they occurred. 65 of 85 died during the study. Tracks in the snow don't lie.

Very interesting study results, I am surprised with the fisher preying on Lynx, in northern Wi, I have been blaming the abundance of bobcats on our dwindling fisher population. Because of competition for food not killing each other. Kill more bobcats.

With the small amount of remains left,they definitely didn't investigate the kills when they occurred.Several days later by the amount of scavenging done on the carcasses.A fisher will not scavenge half a carcass at one sitting,but a couple of lynx from a family group can. Fisher do not prey on lynx. Lynx prey on lynx when the hare cycle crashes. Lynx also kill the odd fisher.

No,cannibalism is a well known behavior in lynx and well recorded.All trappers know this also. No trappers have ever reported fisher killing lynx that I am aware of. Has a fisher ever killed a lynx?Yes most likely.
