I'd think a more plausible explanation would be that birds prefer a location difficult for predators to reach undetected, and which has a wide field of view. I think it's also presumptuous to assume that just because an organism can see something better, means they prefer it. E.g. There's no doubt that humans can see bright flashing multi-colored lights better than sunlight on an overcast day, but I don't think anyone would argue that humans would prefer the blinking lights over the natural ones.
