Brian,
I understand that you've studied the effect of the barometer rising and falling on the performance of the birds, etc. As a tournament bass fisherman, I'm familiar with how fishermen believe it affects fish. I believe it affects more than we know and most likely the performance of rollers also.
What knowledge can you share on the subject?
Thanks in advance!

Darin, I don't have any studied knowledge on it, just my own observations and how it appears to apply in my area. The same birds in different regions of the country might experience totally different results. An example of which is how guys in the deep southern states will often comment about how their birds aren't willing to fly very long in the thick, humid air. But here they don't have a problem with it because, I believe, the humidity flucuates tremendously each day and seems to be constantly changing.
So cal is a mediterranean climate which means very arid. I've noticed two things about the barometer and the birds. In the fall through early spring, our barometer is all over the board. For example the last few weeks have been pegged at 30.60+ inches. Usually when we get the high pressure during this time, the air is very dry. Single digit humidity is not uncommon. Just the other day weatherunderground said it was only 4 percent. That is dry!!!
With the high pressure and dry conditions, the birds have a tendency to want to lift, they are bouyant and it doesn't appear to take much energy to fly. The lack of resistence placed upon them often means less rolling and more flying. Some of my kits, if feed decent and in good condition, will fly for hours and hours pinned out when the barometer is high during this time of year. I have to keep them really reigned down on feed, almost to the point of malnutrietion just to keep their fly time under 20 minutes and keep them low so I fly the rest of the kits before I go to work.
I've also noticed during this time of year that when the barometer bottoms out you can end up with similar effects, only the birds are rolling more and the air seems to be moving around more up above, causing them to fly longer. The result is similiar, but the causes are different in my opinion. Personally I absolutely hate this time of year and the pegged barometer. Its often not even worth flying the birds.
Now, in the summer I've noticed that the opposite is true. It is like when a lake turns over...sort of. During the summer, my birds do their best and fly the lowest on high pressure days. But for the most part, those high pressure days have more humidity. Conversely, it is the low pressure days that they will either sky out in just a few minutes, or not want to fly at all. Wierd, but pretty consistent.
In my opinion the worst conditions are when the barometer is moving, especially if it moving quickly. Doesn't matter if it is going up or down. Moving is bad. Moving means good chance of losing your kit. Nearly every kit I lost has been when the barometer was changing.
Since you mentioned the fishing I'll also mention that ideally I like high pressure for when we are sight fishing. Makes the surface of the water turn to flat glass. It is our understanding that the high pressure is pressing down on the surface of the water, which probably corresponds to why the bite can often suck on high pressure days. Probably increases the volume pressure in the water. And then on low pressure days, the bite gets good. But like I mentioned with the high pressure and humidity. Typically high pressure comes with blue bird skys, which is not so good for fishing where as low pressure tends to bring about more unstable conditions including clouds and storms which in turn, makes fishing good.
I don't believe there is one set of rules that can be applied in terms of how pressure affects our rollers. I believe there are specific circumstances that are somewhat typical in different regions and the flyer has to learn to adjust to what he has learned about them. In the big picture, I have become a firm believer that humidity plays the biggest role on what our birds do over anything else.

Interesting post. When I brought my birds out of California (dry climate) to Arkansas (very humid) there was a marked change in thier behavior.
Interesting!
