Chińskiej fabryki czerpią tzw wpływu choć reżysera czuć zwłaszcza bunt its perfectly logical to assume that cicadas intentionally over produce each generation, this is bc the numbers are knocked down by predators such as bird and wasps and such. once the predators have had their fill they move on and this allows both cicadas and birds the opportunity to mate peacefully and seperately. there a far more cicadas than the birds could consume, hunting becomes gathering and paradigm flips. why would you want to hang out at the grocery store when you got a house across town? I think the hypothesis is OK, but the data is wrong. There are more test variables here that aren't being considered. Primarily, area. But I'm no wildlife biologist. You would have to test at least 40 locations to get a reasonable statistical distribution for this effect. I think that's the problem. It be VT, but we're inundated by cicadae right now, and friends are out back yard abundance Jays have not abated. Mourning dove nesting on porch, etc. But I am making the same error by suggesting that experience can be generalized when it is N=1 Neither am I assuming that alternate experience discounts Madeline's basic null. I'm just saying let's get more data before we infer. 13 and 17 are two special kinds of primes. They are one more than a multiple of four. That's interesting math for some different reasons but they could be taking advantage of the periodicity of bird populations. The two closest beside those are 5 and 29. Those be outside of the acceptable range for development. It would be interesting to breed a cicada that has a five year cycle and unleash it into the wild and if it takes off. But I like the counter hypothesis suggestion that the birds are not out. Showing that bird observations are reduced both before and after is not sufficient. They need to be reduced proportionally and I 't think you have the data resolution for that. If there is a 10% reduction bird populations before the the boom and a 70% reduction of observations post boom you are talking about two different phenominon. It's not enough to show that it's just less. Came looking for a reason Birds had dissapeared googled the cicada and birds and this site appeared. The Hunter Valley Australia is the area I am speaking about I have seen no natives parrots or pigeons and some other pet birds.. They would come to feed at our bird feeder every day and now they are all gone. It has been 1 month now and hardly sighted any birds except a few finches. We are most distresses by their dissapeance.
