Resplendent Quetzal Research Paper

The Puerto Rican parrot or "iguaca" (as our Taino Indians called it) is a bright green bird with a red band on the forehead, a white ring around the eye and the blue primary feathers. Juveniles are quite similar to adults. Both females and males are similar and measure about twelve inches.

Various experiments and measurements were performed in the field in order to compare the two types of rodents. The following is a list of the data collected through multiple observations over a span of two years. We captured 100 rats of each rodent population, and we found the average weight, length, hind limb, and forelimb measurements. In addition, we conducted experiments in regards to their top speed, average height that they could leap, gestation time, and average time spent in the courtship display.

resides in Canada, the United States, and Mexico. This species is migratory through most of its range,

Lake Malawi’s cichlid male population of fish are tested on their ability to build bowers to attract the female population. Altering this extended phenotype, or ability to build bowers resulted in no change of mating, but males that built successful bowers showed to

Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks, female peacocks are attracted to males with long brightly colored tails, even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males with this characteristic have a higher chance of reproductive success and their characteristics being passed on to surviving offspring.

Parus bicolor, commonly known as the tufted titmouse is a small bird species native to many places in North America. The taxonomy for the tufted titmouse follows this hierarchy: Kingdom Animalia, Family Parade, Genus Parus, and species Paris bicolor. Originally, the tufted titmouse only inhabited few areas of the around the South East, and slowly the species migrated up the East Coast, and even a few subspecies have developed in Texas. They thrive best in woodlands, swamps, river basins, and other vegetative areas. Occupying the tops of many deciduous trees, the Tufted Titmouse offers many positive factors to an ecosystem.

The Tamandua Mexicana is a medium-sized anteater with a prehensile(capable of grasping) tail, small eyes and ears, and a long snout. The anteaters can weigh from 7.1lbs to 11.9lbs. Their typical size can range from 102 to 130 centimeters. The anteaters type of symmetry is Bilateral. (which is the same on both sides) Their fur is pale over most of the body except on the upper half of the body where there is a black shaped vest.

These birds most commonly found in North America. It will breed through a wide range from western Alaska and Northern Canada all the way to the west Indies and Panama. The bird is one of the larger birds in its subspecies it weighs about 1.52-3.53 pounds or 690-1600 grams, and measuring 45–65 centimeters or 18–26 Inches in

Ringneck Pheasants only weigh two to three pounds. The females are very blandly colored in order to blend in, but the males have browns, yellows, oranges, and sometimes a dark green. The ring around a Male ringnecks’ neck is a pure white like the spots on their wings, although their long tails are dark colored. They are considered the most commonly identified

Cuba’s national animal is the tocororo bird. One reason why it is the national animal is because it cannot be held captive. If held captive it will not survive for long. The bird reflects on Cuba’s freedom. This bird is only found in Cuba and nowhere else in the world. The only way to tell the female and males apart are there sizes in height. The top of it’s head is black. The torso part of the bird is white and the bottom half of the bird is red. The crown, or the top of it’s head, can be light blue or green. The bird's wings are black with little white lines. Another

tail. They have gray or rosy brown backs with lighter gray or brown hind legs and have

Red Tailed Catfish mating systems are diverse and sexual selection is expected to be stronger in some lineages than others. In particular, polygynous mating systems and female-only parental care set the stage for potentially strong sexual selection by female choice. But does such intraspecific choosiness target the same coloration traits that also determine assortative mating.

From the cross white eye males with wild females, our results were we got both phenotypes in the males as well as the females to be wild type.

Sexual selection can best be described by the definition given by Darwin himself. Sexual selection is “the advantage which certain individuals have over other individuals of the same species solely in respect of reproduction” (Hosken et al, 2011). Sexual selection occurs throughout the animal kingdom, where male frogs dominate through the depth of their croak, and certain peacocks reign superior based on the colour and intricate detail on their tails. They remain superior to their lesser counterparts as they bear more admirable characteristics, from which they are chosen by females of the same species.

The males in most cases are the most active in courtship- they are in fact, the best provided with and are the more attractive of the two sexes in various ways. The attractions are flaunted in an elaborate manner in the presence of the females; and also only during the mating season. It also happens to be, that the individuals of one sex are capable of feeling a preference for a certain individual of the opposite sex according to Darwin. When the above happens, like in the case of the argus pheasant where the females are attracted to the exotic shading of the ball-and-socket ornaments and designs on the wing feathers of the male, it is interesting to notice that the males especially flaunt their great plumes only during the mating season and preferably in the presence of his female counterpart/counterparts. The great plumes which prevent the wings from being used for flight, thus, can be traced to the fact that they were given to the male as an ornament. Also, interesting is the fact that, the females would likely mate with that male argus pheasant who had the greatest plume because it charms them.
