Barometric pressure and animal activity.

While Mule deer hunting, week before last, we had overcast days for four in a row, and even some rain and fog. I saw a young buck with a doe, but he was not giving chase and she was calm. Well, on Friday the clouds cleared up and midmorning I saw a buck actively chasing a doe. Heck they saw me and still came within 50 yards of me. About 5 that evening one of the guys in our party killed a nice Mule deer buck he said from a group of bucks and does on a hillside. So I think of the old saying "wind out of the west fish bite the best, wind out of the east fish bite the least". And Bill Dance explained that westerly wind tends to cause a barometer rise, and easterly causes a fall. So there is some truth to the saying. Same as when the cows are laying around as opposed to actively feeding.

But it seems like overcast days are best for predator hunting. Maybe a difference in carnivores versus herbivores?

What's yall's take?

whin i turn the baromeator in the house ta the east i like ta feast & whin i turns it ta west i likes ta rest. & whin i fart it kinda lingures. my i have cheap posts

I killed a coyote this morning, and missed a second one running. Heavy clouds with a slight off and on mist. And I've always relied on the cows up is good hunting!

Barometric pressure definitely affects animals movement

it affects my wife, maybe its the other thing

I've had better hunting and fishing with a falling barometer

Alright.

Well maybe its simply a moving barometer. Increase in pressure or decrease causes more activity?

But when we had several days in a row of low pressure things stayed slow. Several days in a row of high pressure wouldn't be the same, I think.

When barometric pressure is rising and high creates the most movement. I have a homemade barometric pressure guage I made and definitely works. Learned it from my grandfather years ago and works really well with fish feeding, used to go every time it was up.
Take a mason jar and fill 3/4 with water and then put and old green tinted coke bottle in upside down. When the pressure is rising, the water will start drawing up the bottle and when it's real low it'll actuallyblow a bubble of air out the bottom of the bottle. Takes a few days to start wworking and works best if you set it on a window seal. It works!

not upta date with high-tech. have experienced. the changing of pressure from eating too many bean barretoes, causing on wanted presure on the rear seals, causing massive seapage in the O-ring

Thank you. So my suspicion was correct.

I have heard for years how animals move so much before a storm, which is falling pressure. Others claim movement after a storm which is often rising pressure. I watched 8 hours of deer feeding last night during a steady low pressure, shot a hog and a coyote.

Animals don't stop eating because of changes in pressure or stability of pressure. Also, even if some do, not all are going to respond the same way.

Something to keep in mind is that it may not be whether or not the pressure is changing because it is often changing, but rather how dramatically it is changing.

In other words, regular or slow changes in barometric pressure are not apt to produce abnormal amounts of increased or decreased animal movement.

However, this is contrary to what this guy has found who believes there is a sweet spot for deer movement.
