Beak

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. He appeared, from the point of from everyone around him, too smart for a 6 year old. The thing the kids didn’t know was that he had a photographic memory, so anything he saw he could recall perfectly at any given moment. Evan’s parents were mad scientist and always gave him books for him to read. They also lived underwater. So one afternoon…

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,…

Sometime in November last year, it was announced that Harvey Beaks – a Nicktoon centered around a mild-mannered young bird and his two mischievous friends – was being cancelled after just two seasons on the air, with the remaining episodes being moved from Nickelodeon to Nicktoons. The news came as a shock to most of us, including the show's creator, C.H. Greenblatt, who reportedly learned about the show's fate via an official Nickelodeon Twitter post. To make matters worse for the show's fans,…

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…

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…

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…

similar in their shapes of beaks. They typically eat fruits, insects, some lizards,…

If you look closely at the picture you will see a tall white bird. This bird along with others birds is so special because it has adapted to its ecosystem, the pond. Millions and Millions of years ago Birds in the same location as the pond ecosystem had just legs and no wings, which was a problem. Because the bird got wings The birds also need wings to catch prey, such as flying insects, without wings they couldn't reach it. Another reason the bird would have adapted is because the ecosystem…

Referring to figure 1, it depicts the relationship that time has with finch population and average beak depth when there is an average rainfall of 25 cm. It justifies the first hypothesis as the finch population remains almost the same over the span of five years and the beak depths of the birds are essentially constant. However, in reference to figure 2 challenges the second hypothesis as the overall trends from the results demonstrate that although the finch population does decrease with…
