16 GLOSSARY 



RACE. See SUBSPECIES. 

 REMICLE. See PRIMARIES. 

 RETICULATE. Netted; resembling network. 

 RUFOUS. Of a red or reddish colour. 



RUMP. The lower portion of the back, lying just forward of the base 

 of the tail (fig. 16). 



SCALES. The small horny plates on the tarsus or foot of a bird. 



SCAPULARS. The group of feathers on either side of the back, on the 

 "shoulder" just above the wing (fig. 16). 



SCAPULAR REGION. The shoulder region. 



SCUTELLATE. Like a plate or shield. 



SECONDARIES. The series of flight-feathers attached to the second 

 joint or "forearm" of the wing, and forming a series continuous 

 with that formed by the primaries (figs. 19 and 22). 



SHAFT. The quill or midrib to which the two webs of a feather are at- 

 tached. 



SIDE. The area on each side of the body between the armpit and flank, 

 and the back and breast (fig. 16). 



SPECIES. A group of individuals within a genus having common char- 

 acteristics and relationships. 



SPECULUM. The brightly coloured area on the secondary wing-feathers 

 of many of the ducks, often showing a metallic iridescence (fig. 19). 



STERNUM. The breast bone. In a bird, a deeply-keeled structure to 

 which the wing muscles are attached. 



STREAK. Same as stripe. 



STRIPE. A line of contrasting colour running lengthwise of a feather 

 or of the body. ("Bars" run crosswise.) 



SUBSPECIES. A division of a species; a geographic subdivision of a 

 species; also called "variety" or "race." 



TAIL-COVERTS. The feathers which cover the bases of the tail-feath- 

 ers; there are upper and under tail-coverts (fig. 16). 



TARSUS (pi. tarsi). The foot; that portion from the "heel" to the base 

 of the toes (fig. 17). The tarsus is popularly referred to as the 

 "leg" but that this is incorrect will be seen from fig. 23, in which 

 comparison is made with the human leg. The tarsus corresponds to 

 the human instep, but the bones thereof are fused into a single bone. 



TERTIALS. The innermost series of flight-feathers. The tertials or terti- 

 aries are, properly, the feathers which grow on the upper arm (hu- 

 merus), but such feathers are not very evident in most birds and 

 the two or three innermost secondaries, growing upon the elbow, and 

 commonly different from the rest in form or colour, pass under the 

 name of tertials (figs. 19 and 22). 



THROAT. The area on the underside of the head between the chin and 

 foreneck (fig. 16).
