Have you tried using female traps? Maybe its one of those guy only kinda clubs.

Malukchuk, I’ll have to try and set some female traps next chance I get. I thought maybe some of these males were identifying as female lol.

Seldom, I have read a few coyote studies but I guess I haven’t come across the study you are referring to. I’d love to read it if you know where I can find it. I’m not a new canine trapper, more of an on again off again due to work and family priorities. Just thought I’d ask a question and hopefully get some feedback from some of you well seasoned coyote trappers.

A friend of mine once caught 16 coyotes off of 3 adjoining farms. 14 were female, all were pregnant and 11 of those that were pregnant were probable yearlings. He only caught 2 males. Distemper had gone through that area 2 years before. The coyotes were quickly re-establishing the population.

Mange?

I don’t have the link anymore since it’s been some years since when those types of studies were talked about much on here. I like you would have to do a Goggle search on coyote densities which included the 5-year kill period.

From memory I remember if there are too many coyotes in a given area, the bred female will throw more males in her litter. If the population is down OR there is some increase in prey the female will throw more female pups. Furthermore, the study talked about the depopulating of coyotes from a given area that a 75% reduction in the coyote population every year for 5 consecutive years was needed to stabilize the density at that low level. If one year was missed you’d have to start all over as if you’d never start the reduction.

Seldom, thanks for the info. I’ll see if I can find it. I would be really interested in reading that study.

That study was done by Cornell University. I read it and had it as a PDF, but it was on an older tablet of mine. It should be available somewhere still.

I found it I think.

Sounds like proof that they are welping.

Thanks Keith for finding that paper.
For those in the mood to learn more about coyotes, this is a very interesting study that has pertain to many discussion on this forum.
From the Canadian Journal of Zoology- "Coyote responses to visual and olfactory stimuli related to familiarity with an area"

Maybe gland lure is more inviting to males

Thanks Keith for the link to that study
