Do crows mob gulls? About 4pm yesterday, there were at least two dozen crows calling vigorously from the roofs of my apartment building and/or the air space above them. Search as I would, I couldn't find a raptor but two Glaucous-winged kept circling above.

Max Planck is supposed to have said: A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.Andreas Wagner observed of Planck's remark: Science, like nature, advances one funeral at a time. (Arrival of the Fittest, p.197)
