I was just going through our pictures of our February Trip... when it rained 4 or the 7 days... and during that time I noticed something that I remembered from my Childhood.
This is 100% True.... I bet my 1967 Virgin Sgt Pepper's Lonely Hearts Club Band, Mono on it!
When I was a boy growing up on the coast in Washington, my father told me to took up and look at the seaguls. The birds were all circling. He asked me why they were and I said someone just have dropped a thingie of McDonald's fries (See--- even back then, I was a smartie pants).
He said, that would only be true if they were lower. These Birds were high in the air. And it's an old Canadian Indian Legend that the birds know there is about to be a rainstorm.
I saw this again in Disneyland, 30 years after my father told me. Sure enough, on many occations while at Disneyland, I saw Seaguls circling quite high and each time, within 10 minutes, there would be a short downpour of rain.
It got so common for us that we would seek indoors prior to rainstorms and always just miss getting soaked.
The science behind the myth is that the birds are circling because a low pressure "bubble" has entered that area and there is no prevailing wind direction. The birds are searching for a wind direction. Very shortly, that Bubble will be converged upon by multiple sources (Nature abhours a vaccume) and these multiple pressure convergances will cause instant and intense rain.
I Swear on my 1967 S.... og I said that. Anyways... for everyone down there now... llok up from time to time... If you see the birds circling in large numbers, move indoors. The storm will be very unstable and pass shortly.
I even took pictures of the circling birds over the Rivers Of America. Sure enough, it was only 1 of about 10 examples of how we knew it was about to pour.
(And I am from Vancouver... we KNOW Rain!)
