Two Flycatchers of the Genus Empidonax New to the Fauna of South Carolina

Résumé
This is apparently the only Michigan specimen of this species that has been preserved.It should be pointed out that at Sault Ste.Marie the northern peninsula is only separated from Canada by the width of the Saint Mary's River, so that northern forms may enter our limits most easily at this place.--NOn.•AN A. Woou, Museum of Natural History, University of Michigan.Arkansas Kingbird (Tyrannus verticalis) in Delaware.--OnDecember 31, 1912, while on a collecting trip with M,.Charles J. Pemmck at Rehobotb, Delaware, we fell in with four individuals of this species, two of which were secured.The bi•ds were apparently engaged in catching some kind of small insect near the ground over an old corn field, darting down from the tops of the'stripped stalks aud returning to the same perch in the regular Kingbird mamier.They were rather wild and difficult to approach.On examiuatiou the stomach was found to contain numerous fragments of some small beetle-like insect.The specimens secured were an immature male and female.The occurrence of this species so far to the east of its normal range is further attested by the specimen captured by Mr. F. H. Kmmard ou October 20, 1912, at Monomoy Island, Chatham, Mass., "just off the heel of Cape Cod" (The Auk, Vol.XXX, Jam 1913, p. 112).All of these individuals were thus close to the sea, our birds being just back of the beach, with a strip of salt marsh and narrow tangle of greenbrier interve•fing.It seems reasonable to believe that these were all bi•ds that had bred or been raised in the northern portion of the species' range, possibly somewhere in the Saskatchewan region, and that they went adrift in some westerly gale far to the southeast of their regular track at the outset of the fall migration, reaching the coast of New England and moving to the southward aloug the shore, lingering, without doubt, on the prairie-like stretches of the Coastal Plain in Long Island and New Jersey.--SrENcEnTROTTER, Swarthmore College, Per, ha.The Wood Pewee as a Foster Parent.--Thepast season a pair of Kingbirds reared a brood of young in a burr oak standing near my parlor window.In my yard all sramnet long a lone Wood Pewee took up its headquarters.This latter bird, so far as I could learn, was not breeding -at least there was no nest within a half mile of the house.Early in July we had a severe wind and electrical storm.A few days later I failed to find the parent Kingbirds, though three young, just from nest were about the yard, very noisy all the while.On July 20, when within 100 feet of •hem, I saw a lone Wood Pewee feeding these young Khigbirds-and was an interested spectator of the act for a full half hour --and the same thing was observed daily for about ten days• when the Kingbirds left for other quarters.--W.E.

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.
