This lab was designed to study the birds’ preferences of habitat site, seed size, feeder gradient, and how every species will interact with other species. The study site for this lab was in Hammond Woods, and in order to complete this experiment, we set up 8 types of feeders, which varied in open or closed site, big or small seed, and high or low feeder. The data were collected from different study groups from different time of the day, the experiment started from the beginning of October, and last for 1 week. Before this lab, we came up a null hypothesis that all Chickadee, Titmouse and Nuthatch will show no preferences on seeds size, feeding gradient and habitat sites, which means they will choose open and close sites, large and small seeds,
By creating experimental beach scenarios, negative and standard, Karpanty, et al, increased and decreased the amount of surface eggs to compare the availability and sufficiency to refuel Red Knots in the Delaware Bay area. They were able to determine that horseshoe crab eggs were sufficient and that Red Knots were not excluded when aggressive shorebirds also foraged on the experimental beach areas. The feeding times were mainly during the day and until high tide. It was observed that Red Knots foraged in high-density areas and along the wrack line, where horseshoe crab eggs were visible and easily accessible. Once that area was depleted, the Red Knots would move on to other horseshoe crab nesting areas.
In Biology class we conducted a lab called “Bird Beaks”, in the lab we were separated into four groups of different bird beaks. Our goal was to see which type of beak was more successful, and if evolution occurred. I claim that Evolution did occur in the bird beak lab because spoons were able to survive and grow throughout everything that occurred and tweezys were able to grow and thrive after migration and everything that followed. My first piece of evidence and reasoning, is that spoons survived throughout the whole experiment after two natural selections, a migration of tweezys, a natural disaster, and a mutation. We started with seven spoons and ended with thirteen spoons.
Chalfoun, Daniel F. Doak, and Leah H. Yandow to test how different climate and habitat changes affect the American Pika (Chalfoun. Doak, and Yandow). The abundance of the Pika was tested by measuring the scat density in two mountain ranges, the Wind river and Bighorn mountain ranges (Chalfoun. Doak, and Yandow). The 43 sites for sampling contained different forage availability and throughout time, nine different climate changes that aligned with summer heat and winter snowpack temperatures (Chalfoun.
The experiment failed to reject the null hypothesis because there was no difference between two groups. The statistical analysis found that there was not a substantial enough difference between the high-density and low-density treatments to support the hypothesis that intraspecific competition would affect height and survivorship (Figures 1 & 2). We found that the low-density and high-density treatments were virtually the same and intraspecific competition did not affect height (t ratio=-2.04, DF=426, p-value= .021). For the survivorship variable, we also found that there was not a noteworthy difference in the results (t-ratio=-5.58, DF=458, p-value Functional Ecology Funct
We compared the level of difficulty for the bird to pick the food up and the amount. I found that the bigger the beak was the harder it was to pick up the food but gained a larger amount. The smaller the beak was the easier it was to pick up the food but gained a smaller
Tradeoffs are a frequent occurrence in Nature. They describe the compromise between two optimal but frequently incompatible traits for an organism. Andrea Pomeroy and her team applied this concept of tradeoffs to the western sandpipers, Calidris mauri, of British Columbia Canada, with the trade off of their ability to forage for food against the costs of potential predation. The main idea examined by Pomeroy was to study the spatial usage (The measure of how intensely a site is used for foraging by the sandpipers) at Boundary Bay, to determine how the birds chose their stop over sites during migration based on the tradeoffs between food abundance and predation risks.

Reading The Osage Firebird, by Sudipta Barchan, I learned it doesn’t necessarily have to be physical barriers in your way that you have to overcome. This is a story about a courageous young girl who knew that nothing would get in her way to stop her from pursing the profession she loves. In the beginning the author explains how Betty’s career got started and how she became interested in this profession. The text also states things about Betty’s heritage and background.
When fleeing from a predator, animals forfeit the ability to acquire additional resources and reduce their risk of predation (Frid & Dill, 2002). The avoidance of predation and the need to acquire resources to survive creates a tradeoff that animals must balance in order to survive. Flight initiation distance (FID) can be used to determine how animals perceive the risk of predation in their habitat (Stankowich & Blumstein, 2005). Although FID has been used to identify predatory risk assessments in birds, mammals and lizards, it has not yet been used to evaluate risk assessments in urban dwelling pond turtles. Red-eared sliders (Trachemys scripta) flee from a basking site into an aqueous environment when approached by a natural predator and forgo additional time basking in the sun.
It is common for birds to find their way into homes vents. Vents are an ideal place for birds to build nest in order lay eggs and have baby birds. It is a safe high place that most prey are unable to access. Birds commonly get into bathroom vents, and dryer vents. Although a bird in a vent seems harmless it can cause problems for the homeowner.
The potential effects on the environment and ecosystems with the birds ' continued demised were simply ignored. And with that, Alderman allows the chefs to get the last say, concluding the article on a lighter tone about the importance of occasional
In “The Osage Firebird” by Sudipta Bardhan, the author discusses the life and hard work of Maria Tallchief. Betty Marie, best known as Maria Tallchief, always wanted to be a ballerina. Since she was a kid, until she became an adult, her dream was to be a professional dancer. Maria made her dream come true and became a dancer. Body 1:
The animal I chose to examine for this discussion is the finch, a type of medium-sized bird. In order to determine which individuals in the population is best adapted to their environment, we simply need to observe the natural selection process. The individuals who are most successful at adapting reproduce and pass on the trait or traits that provided it with an advantage compared to the rest of its population to its offspring. An example of natural selection would be Darwin’s Finches, whom of which got their name from Charles Darwin and helped him to develop his theory of natural selection. Currently, the finches, which are located on the Galapagos Islands, are being targeted by a parasitic fly.
Joshua Rabideau 11/10/2016 BIOL 380 – Lab: Monday Black-Capped Chickadee Foraging Habits There are numerous organisms and interactions occurring within any ecosystem. Many times, the interactions between organisms and habitats are based on the energy needs of the organisms. In this experiment, a null hypothesis that the Black-capped Chickadee forages on various trees at random. Upon data analysis of the gathered information, it can be determined that the Black-capped chickadee were not choosing foraging sites at random. The results of a chi square test gave a value of 19,890 which is significantly larger than the 16.812 value needed to void the null hypothesis with six degrees of freedom; the probability that this variation was due to chance is less than .01.
Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.
