ingloriously\u00a0on the back of one of the chick&#8217;s two sleeping siblings and can be clearly seen there. The chick who passed it seemed mildly interested in it for a few moments and then turned away.<\/p>\n<p>At one point one of the chicks picked up an old\u00a0pellet from the floor of the nest and\u00a0tossed it over the side but I missed those shots.<\/p>\n<p>I&#8217;m no expert on\u00a0the biology of raptor pellets but I was\u00a0mildly surprised to see this behavior in chicks so young. As far as I could tell from watching them\u00a0feed, the parents were still\u00a0tearing\u00a0up their food (largely voles) and giving it to them in small\u00a0pieces so I don&#8217;t believe the chicks were consuming bones (though I could be wrong about that). I suspect these pellets were primarily composed of rodent fur.<\/p>\n<p>I&#8217;m also curious about the age at which this behavior typically begins in diurnal birds of prey but my attempt at researching\u00a0the subject\u00a0didn&#8217;t turn anything up.
