The Bicknell’s Thrush has a polygynandry mating strategy (Strong et al. 2004). This is when multiple females will mate with multiple males. Which results in several males fathering a single brood. All the males and females will work to raise the young, if the nest were to fail the females will often attempt to nest again (Goetz et al. 2003). The number of eggs in each nest range between 3 and 4, it takes about two weeks in northern areas for for the young to start fledging. There is usually only a single brood per breeding season (Rimmer et al. 2001). Females choose nest sites based on the amount of food in the area. The Bicknell’s Thrush breeds in areas above 1100 meters in elevation (Rimmer et al. 2001). In its wintering ground, the Bicknell’s

The Northern White-tailed deer have a polygynous mating system (fcps.edu, nd). Most white tails mate in their second year but it is possible for females to become sexually active after only seven months. The male species are polygamous but may develop an attachment to a doe for several days or weeks. The female species come into heat in November for only twenty-four hours. If the female is not mated she will have a second heat...
On an endless road of meadows and half collapsed barns exists a quaint town living its motto “The City of Progress”. Enterprise, Alabama is stuck between miles of bleak pastures and feeding cows, but the peanut factory overwhelms your every breath. The monotonous drive does have a reward, and it can only be found hiding in a valley of small stores and baptist churches on downtown’s main street. It is a statue that reminisces this town’s story of triumph over its struggling economy during the decline of cotton. Sculpted from stone, a woman is presenting a boll weevil in honor for its efforts in destroying the crop, cotton, Enterprise, Alabama’s main economic source.
Some people even step on their nest and bringing pets that kill the chicks and destroy the eggs. As these things kept on happening, their population started to decrease.
The titmouse is a small songbird that searches acrobatically for insects among foliage and branches. The tufted titmouse, also known by their scientific name of baeolophus bicolor, is a widespread species from North America. Because the species is so widespread, it can be assumed that the species is not limited by the biotic and abiotic factors that other species are limited by. The titmouse eats only insects in the summer, including caterpillars, beetles, ants, wasps, stink bugs, and treehoppers; they also eat seeds, nut, and berries. However, every population, or a group of individuals of a single species living in the same general areas, is limited by a carrying capacity, or the maximum population size that a particular environment can sustain. At one point, the biotic or abiotic factors will limit the dispersion and dispersal of the
Legionella pneumophila GRAPH Introduction: Legionella pneumophila are gram-negative rods. They are very difficult to culture because of their complex nutrient requirements, such as cysteine, high concentrations of iron, and the use of activated charcoal agar. They survive as intracellular pathogens of either protozoa or human macrophages. They are most often found in stagnant water reservoirs like air conditioning cooling towers, whirlpool spas, humidifiers, faucets and shower heads, and are infectious when inhaled. L. pneumophila was first identified and named after the American Legion convention of 1976, held in Philadelphia, PA.

Bursitis Does it hurt to move your arm? Is it tender and radiating pain to your neck and finger tips? Do you have a fever? If you answered yes to two or more of these questions, then you may have a typical joint injury called bursitis. Bursitis is an inflammation of the bursa that is easily prevented, detected, and treated.
The finch hybrids before the El Niño of 1983, two different species did not mate each other but during the child, a scandens mated with a fortis and produced four fledgings.
While sitting around your house, watching television, you notice that you have been scratching your arm and in between your fingers for a little while. After taking a closer look you notice something that you assume is a rash and just ignore it. The next day however you notice that the rash has spread and that you think you see burrows in your skin. Then it hits you, the weekend that you spent away on vacation in that not so expensive hotel to save a couple of dollars has now cost you more money in the long run. You must go see your doctor to be treated for scabies!
Thrush, also called oral candidiasis, is a fungal infection that develops in the mouth. It causes white patches to form in the mouth, often on the tongue. If your baby has thrush, he or she may feel soreness in and around the mouth.
The way they raise their young is that by females by nursing the young and collecting grass for their nest. The males play there part by defending their territory and young. The young spends six weeks in the burrow.After six week they go out of the burrow.
Behavioural hypothesis centres on protection of nest and the forming of the mating bond. (Mueller (1990) p. 553-585). This has similarities with the male mating theory.
