Deer Behavior

Last night while sitting in the blind I had a spike appear well before the feeder release time. However for the two minutes this spike was out he was shaking his whole body non stop tail pointed straight back. His shakes were more like a dog shake not trembles, but he did tremble at times. It eventually got the the point where he spooked himself off. Has anyone seen this before, is this a sickness, or did he just have something on him

Horsefly

I would assume he had flies, gnats, mosquitoes or something else. OR .... He kept moving so that you would not be able to get the crosshairs on him!

Fire ants! I've seen where they would do as you describe and run in circles bucking like a bronc.

Probably crab lice attained during the rut.

I’ve seen a spike do this before as well as a few other bucks. I assumed it was horse flies or some other parasite type that was biting it.

I have seen them act that way after they got their [censored] kicked by a bigger buck.

I have seen a doe act like that because of an infestation of ticks on her. I thought she was crazy until I checked game cam and found a close up showing a bunch of ticks on her ears and body. Odd thing was no other deer were infested like she was.
