DEFINITIONS

ECTOPISTES
‡ (Columbidae; Ϯ Passenger Pigeon E. migratorius) Gr. εκτοπιστης ektopistēs  wanderer, migrant  < εκτοπιζω ektopizō  to migrate, to go abroad; "ECTOPISTES  ...  Bill slender, notched. Wings rather elongated, pointed, the first and third quill equal, the second longest.  Tail rounded, or cuneated.  Feet short, naked, anterior scales of the tarsi imbricate; lateral scales very small, reticulate.   Types. Col. speciosa? Temm.  2. Col. migratoria. Linn.  Inhabits America." (Swainson 1827); "Ectopistes Swainson, Zool. Journ., 3, 1827, p. 362. Type, by subsequent designation, Columba migratoria Linné  (Swainson, Classif. Bds., 2, 1837, p. 348.)" (Peters, 1937, III, p. 82). The countless migrant flocks of the Passenger Pigeon were harried by hunters to a level where no viable breeding populations of this colonial nester could exist, and the slide towards extinction became inevitable.
Var. Estopistes, Extopistes.
Synon. Trygon.
