Birds deyan lilly maya final HANDOUT 10-2

  1. 1. Dimitrov, Deyan Mustakova, Lilly Kalcheva, Maya 10/2 Birds 1. Scientific Name: Aves 2. Symmetry of Birds: Bilateral symmetry 3. Birds’ Phylum Birds belong to the Chordata phylum along with mammals, reptiles, amphibian, sharks, bony fishes, and others. The most closely related group to birds are reptiles and both species come from dinosauria(dinosaurs). Mammals, birds, and reptiles are all Amniotes and the last common ancestor of birds and mammal (therefore, humans as well) lived in the Carboniferous period around 360-300 MYA. 4. Derived Characteristics Most of birds’ derived characteristics are adaptations to ease their flying. Some examples are: • Wings • Feathers help flight, thermoregulation, signaling, camouflage, and distinguishing between themselves • Birds are endothermic and have four-chambered heart in order to maintain fast metabolism for energy for flights. • Excellent vision and large brains in comparison to reptiles and amphibians. Their brains help them with visual perceptions • Hollow Bones. They are lighter and allow birds to fly. 5. How Birds Obtain Food • Birds tend to obtain food depending on what they eat. For example insect- eating birds attack from high branches, ones that consume nectar have brushy tongues, etc. • Birds don’t have teeth, thus they can’t chew and consume unmasticated food. 6. Birds’ Locomotion: Mostly by flying 7. Birds’ Lifecycle: Egg->Juvenile->Adult->Breeding->Repeat of Cycle 8. Examples of species: o Bald Eagle (Haliaeetus leucocephalus) Bald eagles, which are commonly known as the symbol of the USA, are found in North America near large bodies of water. There they move by flying and hunt mostly fish, but also other birds, small mammals and reptiles. Thus their ecological role is the one of a predator. Like other birds, bald eagles hatch from eggs and are looked after by both parents for

They can be found in urban areas in all continents, for they tend to nest on buildings. Hus their ecological niche is of cavity-nesting birds. They move around by flying and usually eat grains, seeds and insects. House sparrows’ eggs hatch in 2-3 weeks, after that they stay in the nest for about 12-14 days and reach maturity in 1 year. These birds mate for life, having 3 newborn birds per year. o Ostrich (Struthio camelus) Ostriches are famous as the biggest birds in the present world. As such they can’t fly, but only walk or run, maintaining the highest land speed for living birds. Ostriches live in savannas and desserts in Central and Southern Africa. They eat mostly plants and insects, making their ecological role as ones who feed on plants. Ostriches’ eggs hatch in about 40 days, after that the babies mature for 2-4 years and when breeding lay from 10 to 70 eggs. o Bee Hummingbird (Mellisuga helenae) The Bee Hummingbird is known to be the smallest living bird specie. It’s found in dense forests in Cuba and Isle of Youth. It feeds on nectar and insects and is important for fertilizing several plant species, which live in its range. It moves by flying. Bee Hummingbird’s eggs hatch after 16-18 days and the little birds stay in the nest for about 3 weeks in which they are fed by their mother. When breeding they lay about 2 eggs. 9. Human Uses/Interactions with Birds • Birds’ eggs and meat have been used for food since antiquity; • Various kinds of birds ha been domesticated for food or other uses; ex. pigeons used as messengers, many others are kept as pets; • Some viruses (ex. ornithosis) can be transmitted from birds to man, though that’s rare; • Bird feathers are often used for decoration.
  3. 3. 10. Fun Fact about Birds • During the First World War a post pigeon called Cher Ami even lost an eye and a leg, while doing its job. For its bravery it was awarded with a Distinguished Service Cross and it had its leg replaced with a wooden one. Vocabulary 1. Aves – The scientific name for birds derived from Latin 2. Bilateral symmetry – If you cut a body in half, something that is not normally practiced, you will get two mirror shape halves. 3. Chordata phylum - A phylum that comprises all vertebrates 4. Amniotes – Vertebrates, whose embryo during pregnancy is covered by a membrane. This egg can be both internal (mammals) or external (reptiles and birds). 5. Endothermic – warm-blooded; applies for organisms which try to generate their own heat to maintain body temperature 6. Incubation – Occurs when birds sit on their eggs in order for them to hatch, as eggs need heat. 7. Tetrapod – Vertebrae animals, which have 4 legs 8. Ornithosis – Also called parrot fever; a virus transferred from birds to men; 9. Binocular vision – Seeing only one object at a time; a vision all birds of prey possess 10.Monocular vision – Some birds, such as pigeons, have this. It means to be able to see two objects at the same time, one per each eye. 11. Guano – Bird droppings
