Moose (Alces alces)

In the Oct. 1939 issue of Journal of Heredity, two veterinarians at the University of Minnesota, W. W. Green and Robert Fenstermacher, describe a probable hybrid of this type (Green and Fenstermacher 1939; also see editor’s comments on page 457 of the same issue). The external features of the animal indicated mixed parentage, though overall it was more like a cow than a moose. The mother, a dairy cow on a farm located a few miles north of Duluth, Minnesota, apparently mated in the fields with a bull moose. The calf was blind; Green and Fenstermacher note that “upon autopsy it was found that the lens portion of the eyes was either deficiently developed or absent.” The eyes were preserved for later study, so it may be that tissue is still available for molecular genetic testing.

From time to time, news stories about mismatched moose-cow couples also appear. One was "Bullwinkle, The Lovesick Moose," by reporter Jim Wright, published in the Charleston, SC, News and Courier, on Dec. 11, 1986 (p. 14-A), from which the following material is quoted, relates the escapades of a bull moose (Bullwinkle) and his lady love, the patient cow Jessica. "Several weeks ago during the regular rutting season, Bullwinkle, formerly a sober, responsible member of the Vermont moose community, suddenly

went off the deep end for a comely Hereford cow named Jessica. She lives in a pasture owned by farmer Larry Carrara of Shrewsbury, Vt.

Though Bullwinkle is wild, as well as crazy, he began hanging around Jessica's place, attempting to make time with her. He went through the usual routine for impressing a chosen member of the fair sex: Bellowing, pawing the ground, strutting around, probably flexing, posing and trying to be cool. She, being a Hereford lady and a proper Vermonter to boot, was having none of that, since they had not been introduced.

...Rutting season came and went, but the lovesick moose lingers on in Carrara's pasture. We are not talking about one-night stands here; this moose is thinking in terms of community property arrangements.

Other cervid × bovid crosses:

Axis Deer × Himalayan Tahr

Roe Deer × Sheep

Mule Deer × Sheep

Reindeer × Cow

Red Deer × Cow.

According to the Associated Press correspondent on the scene, Bullwinkle has ceased pressing his suit with the direct approach, and has calmed down considerably. From the description of his behavior, it is clear that he has fallen back on the old waiting game, sometimes known as the "dazzle 'em with chivalry" number. He is mooning around, dancing attendance on Jessica, nudging other cows away from the feed so that she can eat first. No doubt by now, he is opening doors for her and spreading his cloak over mud puddles, trying to show he's a one-cow moose.
