The Question: Sheep have lanolin in their wool to keep the fibers from matting together and protect them from the sun. Angora goats also have a kind of grease, or wax. Is it also lanolin? Is lanolin the allergen for people who are allergic to wool?
The Question: I was northbound on 71 this afternoon, south of Grove City, Ohio the only hilly part of the trip from Jeffersonville to Columbus. I glanced to the right and saw a canine descending the hill. I couldn’t decide – coyote or fox until I got home to the Internet – even though I was pretty sure it as a coyote. I am pretty sure it was not just a stray dog. Granted, it would have been nearly impossible (at 70 mph!) to see if there were others lurking further up the hillside but most references list coyotes as pack animals. Are they often solitary since they are fairly recent immigrants or did I make an identity mistake?
The Question: We have a bird nest in our backyard that was made by a cardinal. Recently, we noticed that a robin seems to be hovering around the cardinals’ nest. The cardinals seem upset by this, and seem to work as a team to keep the robin at bay. Can you explain what is going on?
The Question: What kind of animal builds a 3-4 inches (8-10 cm) high mound of mud balls with a 1 inch (2.5 cm) hole in the top? They look like mini volcanoes. I have found a couple of these in a swampy area near a river. I live in Michigan.
