Clayton, Dale H. | Common grackle anting with lime fruit and its effect on ectoparasites | Anting is stereotyped behavior in which birds ex- pose themselves to fluid-secreting ants or other pun- gent substances. During "active" anting a bird crush- es an ant in the bill and rubs it frenetically through its plumage (Rothschild and Clay 1952). During "passive" anting a bird entices ants to ... | Quiscalus quiscala; Columbicola columbae; Anting; Ectoparasites | 1993 |

Sperry, John S. | Water transport in vesselless angiosperms: conducting efficiency and cavitation safety | Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from cav... | 2007 | |

Clayton, Dale H. | Feather-busting bacteria | I ONCE HAD A COLLEAGUE who delighted in the aphorism, which he proudly coined himself, "If it's too small to see with the naked eye, it ain't there." Sadly, this view may as well be true for ornithologists who study birds only through unaided eyes, binoculars, or spotting scopes. But birds can also ... | Columba livia; Columbiformes; Ectoparasites; Bacteria; Plumage | 1999 |
