Coyote Beds Reveal Females In Estrus

coyote bed estrus 049A3316Female coyotes have one heat, or estrus, a year, sometime between January and March. As the time approaches, mating pairs scent-mark in tandem. The female urinates and then the male usually follows suit and urinates adjacent to it. After mating, the reverse takes place, with males often urinating first and the females adding their scent afterwards.

Once estrus arrives, drops of blood are often evident in the female’s urine, but scent-marking isn’t the only place you see evidence of estrus. If you come upon a coyote bed in the snow this time of year, inspect it closely — the females’ beds often will have drops of blood in or near them (see photo). A recent discovery of a group of five coyote beds showed evidence that at least two of the beds had been occupied by adult females in estrus.

    So interesting that “timing” is so different in other mammals. The first 2 books of yours, that I ordered, came today…’Otis’ & ‘Animal Mouths’……They are both so super awesome! Gorgeous photos….I love the photo of a parent owl with out stretched wings, bringing a meal to Otis or his sister…..wonderful story & lots of words to learn for children! Can hardly wait to read them with my almost 3 1/2 year old grand daughter.
