Abstract: Feather trauma is a common problem among pet birds, especially those with trimmed wing feathers, and often affects remiges and
rectrices. Damage can become chronic if new feathers remain unprotected by fully formed adjacent feathers.
Anting and non-anting crows were in various stages of molting remiges and
rectrices at the time of the observations.
El segundo individuo se detecto el dia 29 de abril de 2013 en la cabecera municipal de Jaumave, Tamaulipas (23[grados]24'41.16" N, 99[grados]22'45.69" O, altitud 749 m); se trata de un individuo hembra de zanate mexicano (Quiscalus mexicanus) con leucismo parcial, el cual presentaba las dos plumas
rectrices centrales sin pigmentacion melanica (plumas blanquecinas).
The family usually inhabits the ventral and dorsal portions of remiges and
rectrices, which are easy-to-sample microhabitats for those examining birds (Proctor, 2003).
The back is pale grey, chest paler and white throat, outer
rectrices white, wing bar white is wide.
Winglike panels extend from the spine like leaves of a book catching a draft of air, while the fringed
rectrices of the wall-mounted work's lower anatomy dangle below them..
De cada individuo capturado se registraron las medidas morfometricas de peso, longitud de ala,
rectrices, tarso-metatarso, largo y ancho del pico empleando una balanza (Pesola) [+ or -] 0,3 de precision y un calibrador digital ([+ o -] 0,01 mm).
(2009) found that tail length and the extent of black on the outermost
rectrices were the best predictors of sex in northern shrikes (Lanius excubitor) on the basis of their discriminant function analysis (DFA).
