The last two summers down here in Southern Cali have been the hottest on record. I do believe in Global Warming, but I don't subscribe to the doomsday GW theory that the oceans will rise and drown everyone, tomorrow. Or that global warming causes the government to put chemicals into sprinklers so that they create rainbows that will steal our children and control out minds.
And speaking of birds nesting in 'odd' places, I once saw one nesting on a model train. And there was another nest in the tree 5 feet away. They nest wherever they damn well please, as long as it suits them.
