1 Goller, FranzSuperfast vocal muscles control song production in songbirdsBirdsong is a widely used model for vocal learning and human speech, which exhibits high temporal and acoustic diversity. Rapid acoustic modulations are thought to arise from the vocal organ, the syrinx, by passive interactions between the two independent sound generators or intrinsic nonlinear dyna...Vocal muscles; Syringeal muscles; Sturnus vulgaris2008
2 Clayton, Dale H.Common grackle anting with lime fruit and its effect on ectoparasitesAnting 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; Ectoparasites1993
3 Clayton, Dale H.Feather-busting bacteriaI 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; Plumage1999
4 Adler, Frederick R.Departure time versus departure rate: how to forage optimally when you are stupidForagers unable to leave a patch at the optimal moment must act as constrained foragers. Extending the results of Houston and McNamara (1985), we compare a blundering forager that leaves patches at a constant rate with an unconstrained optimal forager that leaves patches at the optimal time.Blundering Foragers; Foraging; Marginal Value Theorem1999
5 Shapiro, Michael D.Divergence, convergence, and the ancestry of feral populations in the domestic rock pigeonStringham, Sydney A.; Mulroy, Elisabeth E.; Xing, Jinchuan; Record, David; Guernsey, Michael W.; Aldenhoven, Jaclyn T.; Osborne, Edward J.
6 Shapiro, Michael D.Divergence, convergence, and the ancestry of feral populations in the domestic rock pigeonDomestic pigeons are spectacularly diverse and exhibit variation in more traits than any other bird species [1]. In The Origin of Species, Charles Darwin repeatedly calls attention to the striking variation among domestic pigeon breeds - generated by thousands of years of artificial selection on a s...2010

8 Clayton, Dale H.Biology, ecology, and evolution of chewing liceChewing lice are small, dorsoventrally compressed insects and are parasites of virtually all birds (Fig. 1) and some mammals (Fig. 2). Many chewing lice are host specific, being found on only a single species of host. All chewing lice are permanent ectoparasites and complete their entire life c...Chewing lice2003
9 Woodbury, Angus M.; Cottam, Clarence; Sugden, John W.Annotated check-list of the birds of UtahThe following check-list is a by-product o f studies made by the writers since 1926 in gathering material for a work on The Birds of Utah which is now completed. The list includes four hundred three kinds of birds (species and subspecies) which are admitted to the actual state list and thirty-three ...1949-03
10 Behle, William H.Birds of pine valley mountain region, Southwestern UtahIt has long been a practice among ornithologists to study the distribution, variation, and ecological relationships of birds in areas characterized by diverse physiographic features. Such studies are motivated usually by the desire to aid in finding solutions for the many problems concerning the dis...1943-08-10
11 Bradford, NettieProperty rights of animalsThe problem here treated includes the property rights and spatial relationships o f animals, with special reference to the land vertebrates. With little work done in the way of collecting and compiling materials pertaining to this field, the references and literature were widely scattered. Sources o...1946-11-30
