Wild Turkeys Foraging on Sensitive Fern Fertile Spores

Congratulations to Deb Marnich, the first of many Naturally Curious readers who identified the Sensitive Fern fertile frond visitors as Wild Turkeys.  I had neglected to check and make sure I hadn’t addressed this subject recently on this blog, which is my custom with every post, and indeed, just a year ago there was a post on this very subject.  Judging from the number of correct entries, either I have a very informed readership or their memory is better than mine – quite possibly both!

Wild Turkeys usually forage in flocks as they search the ground for food. Acorns, hickory nuts, beechnuts, ironwood and white ash seeds, hawthorn and witch hazel fruits make up a lot of their diet in fall, winter and spring. In the summer, seeds of grasses and sedges as well as invertebrates are eaten. In winter, when snow has accumulated, leaves of sedges, evergreen ferns, hemlock buds, burdock seeds and spore-covered fronds of sensitive ferns tend to be more accessible and readily eaten.

The fertile fronds of Sensitive Fern (Onoclea sensibilis) persist all winter, sticking up out of the snow as if beckoning to hungry turkeys. Upon finding a clump of these fertile fronds, a turkey will peck repeatedly at them, causing the sori (clusters of sporangia which produce and contain spores) to burst and release thousands of spores onto the surface of the snow.

    Wild Turkeys sure have learned to forage.
