Comparative Study of the Nesting Behavior of Chestnut-sided and Nashville Warblers
Notice bibliographique
Résumé
TI•E study of the Chestnut-sided Warbler (Dendroica pensylvanica) was made during May, June and July, 1945, and that of the Nashville Warbler (Vermivora ruficapilla), during June, 1946.Both nests were in my study area on the west side of Pimisi Bay, just south of the Mattawa River which flows into the Ottawa River at the town of Mattawa fifteen miles farther east.The place is situated in the township of Calvin, District of Nipissing, Ontario.For invaluable encouragement as well as assistance with the correction of this manuscript and helpful suggestions about charts and diagrams, I am particularly indebted to Dr. J. Murray Speirs and Doris Huestis Speirs.Further, I wish to acknowledge the kindness of Mr. James Baillie, Jr., who arranged for me the loan of certain literature from the library of the Royal Ontario Museum of Zoology, and of Mrs. Hugh M. Halliday, who found the nest of the Nashville Warbler and allowed me the free use of her notes.The instruments used in both studies were an ordinary clock with large dial and a pair of 8 x 30 Zeiss marine binoculars.THE NESTS The Chestnut-sided Warbler's nest was discovered in the forenoon of May 27, 1945.The female was just engaged in fastening the bottom to converging stalks of a raspberry bush, about 18 inches from the ground.Two hours later the nest was half finished and the female was sitting in it moulding it into shape with breast and body.Still later a white string was observed lying across the nest and this was eventually woven into the structure.The male was not seen during the building.However, continuous observation was not possible at the time, but Kendeigh (1945) spoke of the males as being "somewhat attentive to the females during the nest-building . .."After a day of rainy and cold weather (temp.54-62 degrees Fahrenheit), during which little or no work was done on the nest, it was finally completed on May 29.During the next four and a half days the nest was seemingly abandoned until, at 4:50 a.m. on June 4, the first egg was laid.The location of the nest was at the northeastern edge of a fairly open space in the woods, overgrown by what later would become a thick covering of tall bracken.In the middle of this space stood a lone poplar tree.For the rest, the area harbored little else than a few sapling white birches and aspen trees, and a couple of red maples and 204 LAWRENCE, Chestnut-sided and Nashville Warblers[ Auk

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
