Résumé
Nesting of Crossbills in Nova Scotia.--During the past winter, which was very mild and open, nmnbers of A•nerican and White-winged Crossbills were found nesting in the vicinity of Wolfville, Kings Co.The first nests discovered were those of the American Crossbill (Loxia curvirostra minor) Jan.31, three in number.Of these, two contained young, just hatched.The others held three eggs, advanced in incubation.These nests were not far apart, in a small, open grove of spruce, fir, and hemlock, and were similarly placed on horizontal limbs of spruces, from twenty to forty feet from the ground and well out from the trunk.Some fifteen or twenty of the birds were constantly feeding about this grove, and by their noisy chatterings and restless movements attracted •ny attention to the•n.Though hardly expecting to find them nesting at so early a date, I nevertheless watched them closely.Soon I saw a single bird leave the feeding flock.I)a•ting anay through the trees he disappeared among the lower branches from which he soon emerged and joined his companions.A careful search among the branches into which this bird had flown, revealed a nest, well concealed amid clustering sprigs of the evergreen.The sitting female carefully watched my movements a• I approached the nest and upon my reaching out to touch her raised the feathers on her crown, Opened her bill, and in short made herself look quite ferocious.. Finally sliding off the nest, she flitted about within a few feet of me, keeping up an angry chirping, in which she was soon joined by her mate.This nest was some twenty feet up, and fully ten feet out from the trunk, saddled on the horizontal limb among clusters of t•e foliage and protected from above by overhanging branchbs.The other two nests were discovered in the same way --by watching the feeding flock, and noting the movements of birds leaving it from time to time.ß During the following months, many other nests were found.Great diversity in choice of nesting sites among individuals of both species was noticed to exist.Nests of the American Crossbill were found in spruces, firs, and hemlocks at elevations ranging from ten to eighty feet.Most nests were found in spruces of large growth and with thick, spreading branches in open woods.Others were found in dense groves of evergreens in the little bunch of foliage at the extreme top of otherwise denuded firs, while still others were found concealed in dead trees of the same kind among the hanging moss and twigs, close to the trunk.A few nests were found in young hemlocks in the little clusters of twigs that sprout out at the junction of the branches and trunk.The character of the woods did not seem to affect the choice of the birds much, provided that cone-bearing trees were near at hand.Thus nests were found in d•T open upland woods as well as in the low dense growths of the swamps, and in woods of.mixed growth as well as in evergreens alone.Nests of the White-winged species (Loxia leucoptera) were found in Vol.XXIII'I General Notes.

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.
