Re: Energetics - was Re: Spinosaurs ate pterosaurs
In my area, I have watched sparrows chase a single moth down to the deck.
The moth will turn suddenly, dodge and weave and the sparrow is right
behind it. I've watched this several times (whilst sitting at red lights
with open pavement in front of me, allowing a good view) and it the
sparrow kinda corners the moth on the ground.
Always seems like a lot of energy to expend just for one moth. I have
to wonder if play doesn't figure in to it.
