    Birds can go to find insects, this can lead to competitive exclusion. Two species competing in same niches, one will drive out the other. Another way birds might partition natural source of food is by having different beak sizes, this cn lead to speciation. If species began to use different habitats within the same area, assuming that one area has the species that feeds on bigger seeds and the other areas has the species that feed on the smaller seeds. Speciation may occur due to genetic isolation , which will cause lack of gene flow. Then divergence from each other may occur due to speciation. Similar to the mockingbird species on the Galapagos island, they differ in traits though they share a common ancestor. The genetic isolation and genetic divergence this leads to…

    a normal day like any day in the year 3000 and little Evan was lonely, for he had no one to play with since all the other kids didn’t really like him.

    In the island of Beak-topia, resides a countless number of birds. To search for food, some fly above the trees, like the toucan, while others swim underneath the island, like the penguin. To hang out with their friends, some get up really early, like the rooster, and some wait until others go to bed, like the owl. All the birds on the island are different, but we still call them birds. There are four basic things that all of these types of birds have in common. They all have beaks, wings,…

    predict the parameter regarding heritability would have the greatest impact on the evolution of beak size in finches because this is the essential requirement necessary for an increase in frequency to occur by natural selection. Evolution is a result of natural selection, so without it evolution cannot occur compared to the other parameters. Also, a population cannot evolve if the trait is not able to be passed down from the parent to the offspring. However, the other parameters that come close…

    Seed Lab Report

    • 3 Pages

    In conclusion, in this lab, we are trying to find how different beak types influence the amount of seeds they collect and how different seed types influence the amount of seeds the beak collects. My hypothesize is that the largest beak (binder clip) will collect the most amount of seeds because there would be more space. The data doesn’t support/support my hypothesis since the relationship between the variables is inconclusive. For instance, the data shows that the clothespin “beak” from the…

    Drought 1: A Case Study

    • 4 Pages

    The trait variation of having a beak of more depth turned out to be advantageous in Drought 1 and helped the finches’ fitness because it was easier for the larger beaks to pick through the AstroTurf for big seeds than for the smaller beaks. The beaks of more depth were inherited by finches in the next generation. In Drought 1 the finches with small (smaller in depth) beaks managed to collect and crush a total of 0 large seeds in Group 1. The large beaked finches (larger in depth) for Group 1…

    Pacific Ocean. Charles Darwin collected these birds on the second voyage on the Beagle in 1831. It is often stated that the finches were the key to the development of his theory of evolution and Natural Selection. They are used as evidence in many of Darwin’s textbooks. The finches Darwin collected included three species of seed-eating ground finches with large, medium, and small beaks; another ground finch with a pointed beak; two species of ground finches that fed on cactus; a vegetarian…

    As it's believed by some experts, birds grind their beaks to keep them in their best condition. It is characterized by the side-to-side sliding of one beak over the other. Clicking: Back and forth sliding of one beak tip over the other, or clicking of the beak, can mean several things. If clicked several times in a series, your bird is giving a warning and should not be handled. If she clicks only once and pins her eyes but is otherwise unthreatening, she is acknowledging something or greeting…

    into the sea. When it was first discovered, the beak of the glacier went down to the northern edge of Heather Island. This island is near Columbia Bay. In 1980, the position of the glacier changed and is still changing today. The beak of the glacier has moved more than 20 kilometers to the north in 2014. It went past Terentiev Lake and Great Nunatak Peak. The beak has moved at least more than a kilometer, but the length that it has moved has not stayed the same. The beak did not move between…
