Notes come from all around Chicago outdoors.

SHED OF THE WEEK

I am truly envious of Chad Miller, who found five shed antlers (see top photo) and saw five woodcocks in four long walks in Lake County. Not sure if I am more impressed by the sheds or the woodcock.

SOTW, an occasional note on shed antlers found around Chicago outdoors, runs when worthy in the special two-page outdoors section in the Sun-Times Sports Saturday.

A: It’s the first time I heard of this, but it is a thing. Closest I could find for a scientific explanation came from Frederick Schueler, an Ontario naturalist, in a post for Ontario Woodlot Association. We found “by trial feeding of goats and domestic rabbits, that this blue urine was caused by a diet of Rhamnus cathartica, the common, European, or cathartic buckthorn, an invasive alien shrub of old fields and forest edges. The urine of domestic buckthorn eaters is initially yellow or brown, but within ten minutes of exposure to sunlight turns bright blue in the snow or on paper. I’d been watching for rabbit-browsing of buckthorn since the winter of 1998-99, and the blue spots occurred the only time I saw them eating buckthorn.”
