We caught the culprit! After 8 chickens down, boarding up the coop to no avail, and bringing the chickens indoors for a few days (into the unfinished sunroom), we will finally have chicken peace at the Basecamp at least for a while. This weasel was live trapped in the coop and relocated to another section of the valley, over 8 miles from Mazama, and far from chickens and human settlement. We hope she likes her new home.
The differences we learned about long tailed weasels and a short tailed weasels are:
*Long-tailed weasel (Mustela frenata) tail is about half the length of their body or longer (44-70%). Their total length is between 28-42 cm.
*Short-tailed weasel (Mustela erminea) tail is about a third (30-45%) of its body length. Their total length is between 19-34 cm. Females are smaller than males for both species due to sexual dimorphism; some overlap exists between male short-tailed and female long-tailed weasels.
