Anting turkeys

Type that phrase (“anting turkeys”) into google and you’re likely to get “did you mean hunting turkeys?”  No, of course not, I meant exactly what I typed — are wild turkeys one of the birds that use anting behavior to cleanse themselves of parasites?  And yes, they are. (Read more about this behavior in Bird Watching Daily.

Great Tit anting behavior (observed last May 216 in Wales) is typical of what birds do to rid themselves of eternal parasites.

Over 200 bird species have been observed to search out areas where ants are likely to be found, immerse themselves in the dirt and dust there, and fluff their feathers as if they were bathing.  With a big bird like a turkey, it’s quite a show.

Five Wild Turkeys immersed themselves in pine needle fluff and dirt. Apparently this is a favorite place to go “ant”, because there were numerous turkey-shaped scrapes in the hillside.

Scrape the dirt, fluff feathers, and wiggle around until a good layer of litter and dirt works its way into those feathers.

And the reason for this behavior — ants release formic acid as a deterrent to being disturbed or threatened, and formic acid turns out to be a relatively good miticide (i.e., insecticide for mites).

Crouched down in the litter, the first thing turkeys did was scrape the dirt vigorously with their bill. Was that to agitate the ants and get them moving?

Get those legs into the actions as well, and stir up the litter and dirt behind and beneath them, while rustling feathers.

“But that’s not the end of the story.  The ants having released their toxic chemical are now fair game to be eaten, and provide some nutrition if a bird eats enough of them. So, as the bird preens its feathers after its ant dust bath, it can safely consume any stray ants it comes across — sort of like a dessert menu item. And this was quite nicely proven in an experiment by two Cornell biologists (in 2009) who observed that Blue Jays ate 90% of the ants that had been relieved of their formic acid, but engaged in anting behavior instead with ants that were intact (containing their sacs of formic acid).” (Backyard Biology, May 5, 2016)
