Masked Crimson Tanager - Behavior

Behavior

The Masked Crimson Tanager has been speculated to engage in reverse sexual dominance behavior similar to their congener pair, the Silver-beaked Tanager. The Mask Crimson Tanagers, who belong to the passerine bird order exhibit this behavior similar to that of their cousin. However, there is no observable evidence to support the hypothesis that the Masked Crimson Tanager are among the rare and unexplained phenomenon of reverse sexual dominance. Under normal circumstances, passerine species of birds exemplify a default hierarchy of dominance wherein larger, heavier birds tend to dominate the smaller, lighter birds and males tend to dominate females. Between Masked Crimson Tanagers and the Silver-beaked Tanager, individuals engage in a form of interference competition, also known as competition by resource defense, when partitioning resource-rich habitats. The Masked Crimson Tanager prefer to inhabit sites close to or around oxbow lakes, a common geographical feature of their native Amazonia. They demonstrate aggression while defending the more productive areas around the lakes, causing the Silver-beaked Tanager to occupy the riparian forest. The Masked Crimson Tanagers are competitively superior and dominate most interspecies interactions with their cousin.

Famous quotes containing the word behavior:

    This whole business of Trade gives me to pause and think, as it constitutes false relations between men; inasmuch as I am prone to count myself relieved of any responsibility to behave well and nobly to that person who I pay with money, whereas if I had not that commodity, I should be put on my good behavior in all companies, and man would be a benefactor to man, as being himself his only certificate that he had a right to those aids and services which each asked of the other.
    Ralph Waldo Emerson (1803–1882)

    School success is not predicted by a child’s fund of facts or a precocious ability to read as much as by emotional and social measures; being self-assured and interested: knowing what kind of behavior is expected and how to rein in the impulse to misbehave; being able to wait, to follow directions, and to turn to teachers for help; and expressing needs while getting along with other children.
    Daniel Goleman (20th century)

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)
