Uh oh… I\u2019ve been spotted! The Blue Jays (Cyanocitta cristata<\/em>) on guard have ratted me out.<\/h5>\n
\n
\"\"Halt! Who goes there? Thought you could just slip past, did you? Not on my watch. Hey everybody<\/em>\u2014look! Look! Over there!<\/em>\u201d<\/h5>\n<\/blockquote>\n
Now every non-human ear in the neighborhood knows I’m here. It feels a bit like being caught at an awkward moment by the paparazzi.<\/h5>\n
But I don\u2019t take it personally. I know everyone who wanders past is subject to the same protocol\u2014people, cats and dogs, hawks, snakes, you name it. Blue Jays take sentry duty seriously. Any real or imagined threat to the park citizenry is duly noted and announced.<\/h5>\n
Blue Jays are part of a large family. Their Corvidae cousins include gray jays, nutcrackers, crows, ravens, and magpies, as well as some species we’re not that familiar with in North America–choughs, treepies, and jackdaws. In the Americas alone there are over 30 different species christened with some variation of the \u201cjay\u201d brand. The five scrub jays (Aphelocoma <\/em>spp.<\/em>) and the pinyon jay (Gymnorhinus cyanocephalus<\/em>) closely favor one another, but two members of the North American branch have made striking and unique sartorial choices. Once you\u2019ve seen a Steller\u2019s jay (Cyanocitta stelleri<\/em>) or a Blue Jay you\u2019ll never mistake them for any other bird.<\/h5>\n

\"\"<\/p>\n

Of course, none of those feathers are actually blue. It\u2019s just a trick of the light called a schemochrome<\/em>. If you find a Blue Jay feather you can watch the color disappear and reappear as you roll the shaft between your fingers, changing its position relative to the sun. These forest defenders are high-tech.<\/h5>\n
When they’re not spying on everyone, Blue Jays pitch in to give the next generation of trees a head start. Okay, that\u2019s probably an accidental community service, but still… Jays bury acorns and then fail to use them all at snack time. The seeds germinate and\u2014poof!\u2014you\u2019ve got a new oak tree. If society benefits from your actions, intentional or not, shouldn\u2019t you get some<\/em> credit?<\/h5>\n
\"\"Despite their public service efforts, Blue Jays have a reputation as bad birds. Maybe it\u2019s that black mask. More likely, it\u2019s the abuse of power so often attributed to their ranks. Eye-witnesses tell of raids on the nests of other birds for eggs and hatchlings, but one extensive study of Blue Jay feeding behavior found only 1% of the sample population had evidence of eggs or birds in their stomachs.<\/h5>\n
You\u2019ll also hear stories of Blue Jays who trick fellow backyard residents into leaving the feeder-buffet by mimicking hawk calls. Now, I can\u2019t deny that some bullying does occur. Think of it as the price of protection, if you must, and keep in mind that\u00a0Blue Jays have complex social systems and tight family bonds… for whatever that’s worth to you.<\/h5>\n
Judge not, lest ye be judged.\u00a0 Whether the scale tips to the right or the left depends on your point of view.\u00a0 Blue Jays, like most of us, are a mix of positive and negative traits… rarely angels or devils, most often somewhere in-between.<\/h5>\n
Life isn\u2019t always black and white, or even shades of gray.<\/h5>\n
\"\"Sometimes, it\u2019s not even blue.<\/h5>\n
