In a population of blue-black grassquits, song birds found in the tropics of South America, nests within territories of displaying males are at greater risk of predation by avian predators than areas without them, suggesting a trade-off exists for fathers between attracting new mates and protecting their existing offspring.R. Dias, et al., "Experimental evidence that sexual displays are costly for nest survival," linkurl:Ethology,; 116:1011-19, 2010.Spiders duped by bug predatorBy comparing spiders' reactions to different stimuli landing in their web, researchers found that assassin bugs trick their spider prey by mimicking the vibrations on the web made by the spider's own struggling prey, causing the spiders to come within striking range.A. Wignall, et al., "Assassin bug uses aggressive mimicry to lure spider prey," Proceedings of the Royal Society B: Biological Sciences, AOP, linkurl:doi:...
