Chickadee Foraging Habits Lab Report

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.

Competition is fierce in the Everglades. The playing field is filled with native species, hungry for a win. A beautiful door is opened, and majestic Burmese Pythons slither in. These Burmese Pythons take over with their huge appetites and sharp teeth. These eating machines don’t provide a benefit to the Everglades, instead, they harm the ecosystem.

Bootleg Pheasants The South Dakota pheasant, a treasured resource fully protected by a regulated hunting season, provisioned the pantries of law-abiding residents with savory meals. During the fall hunt, shotgun toting men and boys with highly trained bird dogs tramped through the farm fields in pursuit of their prey. Subsequent to a successful hunt, wives and mothers canned the birds in quart jars to preserve the meat. During prohibition, roast pheasant under glass became the ultimate in fine dining in Chicago. Consequently, a robust and lucrative market emerged for fresh pheasant, which didn’t subside during the off-season.

The Golden Cheeked Warbler eats insects and spiders. It is also known to eat caterpillars during the breeding season. This is an insectivorous bird, meaning it only eats insects and invertebraes. They pluck the insect from the surface that they are sitting on, or grab them while in flight.

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.

El Yunque Introduction: El Yunque is a tropical rainforest, located on the far east side of Puerto Rico, and is home to a plethora of animals. At El Yunque there 50 species of birds, 11 species of bats, 8 species of lizards, and 13 species of tree frogs. El Yunque also is home to important animals native only to Puerto Rico such as the Puerto Rican Parrot, Puerto Rican Boa, Puerto Rican Broad-winged Hawk, and the Puerto Rican Sharp-shinned hawk. Two abiotic factors in El Yunque that can affect the ecosystem include sunlight and rainfall. Sunlight and rainfall are an important abiotic factor in El Yunque because sunlight starts the food chain, helping producers thrive, and the rainfall is also important because it’s essential to all the plants

Mrs. Hale and Mrs. Peters contemplate this disturbing discovery, and they wonder who else could be capable of this act of violence. They know Mrs. Wright surely did not do it, as she cared for the bird greatly, she even “used to sing real pretty herself” and the women have already concluded “she would’ve liked a bird.” That leaves Mr. Wright, and due to the fact that he broke the birdcage, it is only reasonable that he killed the bird as well. This realization that the women make leads them to what the men have been searching for all day, a motive. Mr. Wright likes the quiet, so he killed the singing canary which happens to be the only thing bringing happiness to Mrs. Wright.

Her Aunt Ophelia had kept one before. Not a Lilac Macaw, but a Macaw nonetheless. She had a strong fascination with birds, particularly in the Lilac Macaw, whom she had read about once in a souvenir book she received at the New York

The scarlet ibis is in the wrong environment because it’s not in its native tropic environment, and Doodle won’t fit in with the other kids in school because he is different. When the family sees the red bird they wonder what kind it is and the father looks it up,“ ‘It's a scarlet ibis’ he said, pointing to a picture. ’It lives in the tropics-South America to Florida. A storm must've brought it here’ ”(424). The setting of this story is in North Carolina and the scarlet ibis lives in the topics, so the bird is far from home and doesn’t fit in with this environment.

Flannery O’Connor’s The King of the Birds is a narrative explaining the narrator’s obsession with different kinds of fowl over time. The reader follows the narrator from her first experience with a chicken, which caught the attention of reporters due to its ability to walk both backward and forward, to her collection of peahens and peacocks. At the mere age of five, the narrator’s chicken was featured in the news and from that moment she began to build her family of fowl. The expansive collection began with chickens, but soon the narrator found a breed of bird that was even more intriguing; peacocks.

Title Abstract 150 Introduction500 405 Personality is a range of correlated behaviours that are expressed in different contexts. Animals exhibit behavioural syndromes, which is a set of behaviours seen in multiple scenarios. (huntingford 1976 as read in Pelligrini et al., 2010)..Find this!. An example of a behavioural syndrome is the shy/bold continuum (i.e. proactive-reactive) (Wilson et al., 1994 as read in Pellegrini et al., 2010). Boldness has been studied in many species.

At the conclusion of each of the three trials, the number of caterpillars that showed peck marks was tallied. The average of the three trials revealed that 0.67 out of 8 patterned caterpillars had been pecked and 2.67 out of 8 of the solid colored caterpillars showed signs of avian predation (Figure 1). The average rate of avian predation for the three trials was 8.3% for the patterned caterpillars and 33.3% for the solid colored caterpillars. The number of patterned caterpillars pecked was less than the number of solid colored caterpillars pecked for all three trials. It was observed that there were no adhesive issues, weather related damage, or interference from tree

I was shocked that Wilson did not think he would try to destroy his mahogany table causing a ruckus. The bird lived with him for three short days and Wilson was tempted to restore him to his natural habitat but eventually the bird had died. I learned from Wilson these birds are twenty inches long with black feathers appearing green in the sun light with eyes a vivid yellow nostrils covered in white, their is much more detail to this wood pecker that Wilson describes so well in his writing. The ivory billed woodpeckers do not migrate and they also lay their eggs in the hollow trees the trees that are always very large, they eat insects and

Factors That Led to the Establishment European Starlings The European starlings were brought to the U.S, originally arrived to New York City in 1890 and 1891 with the purpose of introducing animals mentioned in Shakespeare’s works. However, the starlings stuck in the U.S and spread outward from New York to the rest of the U.S and their population has since grown to an estimate of 140 million birds. (1) The starlings are “habitat generalists”, meaning they are able to exploit various habitats, nest sites and food sources.

As a result of overpopulation, industrialisation and urbanisation we, as humans, are destroying the natural world that supports millions of other animal species. Our actions interfere with and sometimes destroy entire ecosystems; this will cause animal populations to decline and inevitably go extinct. We need to look at the long term affects our actions are having, we need to investigate what destroying the natural world means for the survival and sustainability of our race and all other species on Earth. One way to investigate this is by focussing on specific interactions that certain species have on their surrounding environment. I have decided to focus on vultures in South Africa because I feel vultures play a very important role by disposing of carrion (dead animals) that would otherwise be a breeding ground for disease and bacteria.
