ALTRICIAL GRALLATORES — HERODIONES. 



Hab. — The whole of temperate and tropical Nortli America, north to latitude about 60°, south 

 to Guatemala. Cuba; Jamaica; Bermudas. Occasional in Europe (18 British records!). 



Sp. Chab. — Adult : Ground-color of the plumage ochraceous-buft' ; but this densely mottled and 

 finely sprinkled above with reddish brown and blackish, the latter color prevailing on the dorsal 

 and scapular regions, where the feathers have lighter edges, the buff prevailing on the wing- 

 coverts, where the variegation consists of a finer and sparser sprinkling of the dusky and brown ; 

 on the tertials and ends of the secondaries, the reddish (a sort of cinnamon shade) Ibrms the 

 ground-color, and is thickly sprinkled with irregular dusky dottings and zigzags ; pectoral tufts 

 nearly uniform dark brown, the feathers with broad lateral borders of clear yellowish ochraceous. 

 Pileum, rusty brown, darker anteriorly, changing gradually backward into the greenish olive-gray 

 of the nape ; sides of the head and neck yellowish ochr.lceons ; a malar stripe of dark ferruginous, 

 changing posteriorly into a very conspicuous stripe of blue-black (or in some specimens dull 



grayish) down each side of the neck ; chin and throat white, with a very narrow medial dusky 

 streak, suffused with ochraceous ; foreneck pale buff", with sharply defined stripes of cinnamon- 

 brown edged with a black line ; lower parts pale buff', witlniarrower brownish stripes ; tibiae and 

 crissum plain light creamy butt' ; primaiy-eoverts ami primaries dark slate, tipped with pale red- 

 dish ochraceou.s, finely, but not den.sely, sprinkled with dusky. Upper mandible olivaceous-black, 

 the tomium (broadly) lemon-yellow ; lower mandilile pale lemon-yellow, deejier basally, with a 

 stripe of dusky brownish along the posterior part of the tomium ; lores and eyelids lemon-yellow, 

 the former divided longitudinally by a median stripe of dusky olive, from the eye to the base of 

 the upper mandible ; iris clear, light sulphur-yellow next the pupil, shading exteriorly into orange- 

 brtiwnish, this encircled narrowly with black ; legs and feet bright yellowish green ; claws pale 

 brown, dusky toward points.^ Young : Similar to the adult, but more reddish, the mottling coarser, 

 and with a tendency to form ragged transverse bars, especially on the posterior upper parts. 



Length, about 24.00-28.00 ; expanse, 37.00-45.00 ; weiglit about U lbs. (Audubon) ; wing, 

 9.80-12.00 ; tail, 3.10-4.40 ; culmen, 2.50-3.20 ; depth of bill, .50-.65 ; tarsus, 3.10-3.85 ; middle 

 toe, 2.90-3 GO ; Ijare portion of tibia, 1.00-1.35.2 



In the large collection of specimens of this species which we have been able to examine and 

 compare are certain variations of plumage and proportions, which appear, however, to be cliiefly, 

 if not entirely, of an individual and seasonal character. The most apparent difference as to colors 

 consists of a more reddish shade to the plumage in autumnal birds, while those obtained in the 

 spring or summer are characterized by a more grayish aspect. There is also another noticeable 

 dift'erence between specimens, namely, in the distinctness of the black or dusky stripe along the 

 side of the upper neck. This is usually a deep glossy black ; but in many individuals it is
