Mallard Migration
The mystery of migration patterns of Mallard Ducks is fascinating. Understanding a migratory pattern and reasons for migration, can help me learn the behavior of a certain species of a duck and help me in knowing when and where to hunt. Mallard ducks migrate south every year from their breeding grounds. The reason they do this is the shortage of food in the winter months. As they make their way south, they use many different paths such as flyways.
Presently, “Mallards are thought to be the most abundant duck on Earth” (National Geographic). In addition, Mallards are the most common ducks in North America. Mallard duck migration is a mystery currently being studied by the Missouri Department of Conservation. “The Mallard

In fact, there are four major flyways a Mallard Duck may take. “The Pacific flyway, which is four thousand miles from north to south and one thousand miles from east to west” (Waterfowl Migration Flyways). “ From the Arctic to the west coast of Mexico and the Rocky Mountains to the Pacific Ocean, this flyway encompasses the most varied waterfowl habitats in North America” (Waterfowl Migration Flyways). “The Central flyway is massive, covering more than one million miles across North America’s interior” (Waterfowl Migration Flyways). “The Mississippi flyway is more than two thousand three hundred miles long and the water shed covers one and a half million square miles, the Mississippi River is North America’s greatest waterway and the most heavily used migration corridor for waterfowl and other birds” (Waterfowl Migration Flyways) . “The Atlantic fly way stretches from the Arctic tundra to the Caribbean” (Waterfowl Migration Flyways). “The Atlantic is the most densely populated of the four flyways and many waterfowl habitats in this region are threatened by development and urban sprawl” (Waterfowl Migration …show more content…
Many scientists that have studied the waterfowl migration, have figured out that ducks use the sun, stars, and stellar maps as visual cues to migrate (Ducks Unlimited). Also, ducks use landmarks such as coastlines, mountain ridges, and waterways are used as directional cues (Ducks Unlimited).
Some of the nonvisual cues used in duck migration is the Earth’s magnetic field, and homing. Since navigation and migration behavior is very difficult to study, some Mallards have been marked with GPS satellite telemetry units to aid in the study.
In the spring, Mallards hens will always go back to the same breeding grounds they hatched in and their mating partner for that year will follow them. They will live here until the winter weather causes a food shortage and pushes them out. Therefore, this causes them to follow a flyway path
Therefore there was a recorded 8 birds, 1 dove, 5 magpie goose and 2 pacific black duck, 3 weeks after the floods. By 2017 the total of 8 birds, 3 species have now increased to a total of 25 birds, 6 species in 4 years. Though this being said many of the birds are ‘new’ to the area such as the 15 Cotton pygmy Geese and 4 recorded Dusky Moorhen. 6 bird species were seen/recorded in 2017, these being the 2 Black cormorant, 1 pacific black duck, Cotton pygmy, Dusky moorhen, little egret and willie wagtail. Other bird species such as the magpie goose which had a number of 41 recorded in 2009, 5 in 2013 and now 0. This indicates that the diversity of birds and population has decreased as a result of their habitat loss and or an a adequate supply of food.
The Ducks In the Central Park Lagoon are impactful to the book because they represent the exact opposite characteristic than that of the main character Holden. The ducks represent beneficial decisions at times of adversity, while Holden struggles to guide himself in the right direction at these times. Holden is very hung up on where the ducks in the pond go in the winter when the pond is frozen and no longer suitable for them to live in. Holden will often bring it up during conversation, as he did with a cab driver, he asked “well, you know the ducks that swim around in it? In the springtime and all? Do you happen to know where in the
The Hawaiian Duck is blessed with one of the best habitats in the world. It resides in the beautiful islands and the epitome of all beautiful islands known as Hawaii. They are mostly found in lowland wetlands, river valleys, and mountain streams. This works to this bird’s advantages. They mostly try to stay away from the more urban parts of Hawaii and stick to their usual wetland setting. However, there not much of these habitats around on the virtually miniature island of Hawaii, which makes this bird’s effort of trying to stick around, just that much harder. Its endangerment has a large part to do with the fact that you cannot find all of these elements in many places on the island of Hawaii. The Hawaiian duck’s habitat is a huge part of what this bird is and how it functions through its
increase in hawks, weasels, badgers, and foxes to this new habitat. Eagles and bear populations
The ducks are first brought to the reader’s attention while Holden is visiting his teacher, Mr. Spencer, regarding his removal from Pencey. While conversing with Mr. Spencer, however, Holden’s mind drifts elsewhere. His mind drifts back to New York as he wonders to himself if the lagoon in Central Park is frozen over, and if so, where do the ducks go? A direct parallel can be drawn from the ducks in the lagoon to Holden’s present situation. He is mandated to leave Pencey, but has no idea where he belongs after leaving. Just like the ducks in the lagoon, “Holden is essentially homeless, frozen out” (Trowbridge par. 1). Holden’s life has not been filled with an abundance of stability and now what little he had is gone, albeit due to faults of his own, and he sees an unsure and hazy future. Holden inquires about the state of the ducks to the driver of the first cab he catches in New York, and the driver believes that he is kidding. Later on, he asks another cab driver if somebody came around “in a truck or something to take them away” or if they flew away “by themselves” (Salinger 81-82). Knowing what happens to these ducks, knowing that they are safe and secure even though the lagoon is frozen would provide Holden with a sense of comfort about his current state of affairs. What seems to be a ridiculous and meaningless question to the
The wetlands of spring welcomes migrating shorebird species, including sandpipers, stilts, plovers, dunlins, curlews, and avocets. The colors of summer come alive with an array of birds atop trees with beautiful sounds filling the air. These include black-chinned, calliope, broad-tailed, red-tailed hawk, white-crowned sparrow, tanager and rufous hummingbird. Cranes and geese make their appearance in early fall, coyotes, northern shovelers dabble on the water, javelina, and mule deer idle or prance about in the open meadow, and wild turkeys trek in their roosting
Where do the ducks go during the Winter when the water is frozen? In The Catcher in the Rye by J.D. Salinger, the character, Holden Caulfield, has an underlying mental condition. He failed out of four schools; he saw his friend commit suicide; and his younger brother died of cancer. These life-changing experiences paved the way for Holden’s insecure and unstable life. By his narration, Holden hints at his disorder throughout the book without fully explaining his condition. Holden’s many insecurities, his teetering on the edge of childhood and adulthood, and his irrational ideas help the reader realize that Holden has a mental problem.
There are thousands of duck lodges located all across North America. Duck hunting has increased in popularity over the past 15 years mostly due in part to the popularity of it on T.V. With that being said this has caused a large increase in the number of lodges being created, to be able to keep up with the demand. Jobs in this field are found all over North America, they range from Alaska all the way through Canada, and as well as all over through South America. Jobs relating to this career are mostly found around high trafficked areas of migrating waterfowl, places like Stuttgart, Arkansas (known as the rice and duck capital of the world), Salt Lake City, Utah, around many small towns in North Dakota, and the Outer Banks of North Carolina.
To determine the migratory patterns and population patterns of the Barn Swallow, I examined different charts provided by the BPP website that allow me to examine the population numbers of Barn Swallows in different parts of North America during their mating seasons. According to the information provided by the BPP website, Barn Swallows have a tendency to live closer to areas that have a higher amount of water. This means that they nest in areas where the climate is more damp. Barn Swallows make their nests out of mud and twigs which makes it necessary for them to live in areas where the environment has more rain or is damper so that they can use the mud to create their nests. The information provided by the BPP clearly shows this due to the fact that throughout the years, larger populations of Barn Swallows are shown to be along the eastern coast and the Great
They start investigating this method by choosing the Hartford Country in Connecticut. They also kept in touch on which hawks they would like to investigate, around 11 Red tailed hawks are radioed bugged and kept in surveillance by the research group. They took pictures of the area to mark
The ducks represent Holden himself in the beginning of the story, because he’s moving around; they highlight his curiosity (and the overall curiosity of youth), and show transition (he’s in a transition between school and
The ducks are first mentioned when Holden is at Mr. Spencer’s house. When Mr. Spencer is asking Holden about his failure and his future, Holden’s mind goes on a digression about the ducks. Holden is subconsciously thinking about, and worrying about his future. He does not understand how the ducks can change so easily and adapt to a changed environment. The lagoon freezing over represents Holden’s life, which is similar to a half frozen lake. He is stuck in the phase between childhood and adulthood. To Holden, the ducks mean flying away, and changing his life completely. He does not like change at all, and is fascinated by how the ducks can so easily adapt to a changing environment.
This week's weather change could be a boon to duck hunters, as a freeze up north should drive some new birds down into the Grasslands. Last Saturday, my son Bill and a friend had a pretty good shoot at the Santa Cruz Club south of Los Banos. They had a good early morning flight, mostly Greenwing Teal and Northern shovelers. They ended up with 11 ducks, including one Canvasback, before the flight ended about 10:30 a.m. To make it more challenging, they were both shooting 20 gauge shotguns. My son is still shooting the same Remington Model 58 that I gave him in 1970, when he was 13 years old. The public shooting areas showed some increase in averages last Saturday in the Sacramento Valley with Delevan and Sacramento Refuges being the best. In the Los Banos Complex, Merced and Los Banos units picked up to around two birds per hunter.
Throughout the novel, Holden questions what happens to the ducks in the winter time, where do they go. Salinger illustrates Holden’s infatuation with the ducks symbolizes the struggle he has with growing up and relates it is as a sign of lost innocence. The first mention of the ducks, “I was wondering where the ducks went when the lagoon got all icy and frozen over. I wondered if some guy came in a truck and took them away to a zoo or something. Or if they just flew away.” (Ch.2 P.13) shows Holden’s concern for innocence. The lagoon getting icy and frozen is really talking about when a person goes through a transformation from kid to adult, the ducks symbolizing the innocence
This study’s purpose was to learn and investigate the different aspects of Batesian mimicry, learn bird species common to the area, their different foraging behaviors, and investigate if a modification to their foraging behaviors can be implemented through learning. We will also measure the
