Question

Roundtrip cost on Amtrak from Oakland, CA to Las Vegas?

Answer 3

There is no longer train service to Las Vegas on Amtrak. You can take the train to Bakersfield and then get bus service to Barstow and Las Vegas. If you don't have a problem with flying, Southwest Airlines has promotional fares from Oakland to Las Vegas from $59 to $79 going and $101 to $144 returning. Of course if you don't plan on traveling during the holidays you might get less expensive return fares.

Owl Pellets

--------------------------------------...

Owl pellets are masses of bone, teeth, hair, feathers and exoskeletons of various animals preyed upon by raptors, or birds of prey. Pellets are produced and regurgitated not only by owls, but by hawks, eagles and other raptors that swallow their prey whole of in small pieces. Owls feed feed early in the evening and regurgitate a single pellet approximately 20 hours after eating. Unlike snakes, the protein enzymes and strong acids which occur in the digestive tract of raptors do not digest the entire meal. The relatively weak stomach muscles of the bird form the undigested fur, bones, feather etc. into wet slimy pellets. In this process even the most fragile bones are usually preserved unbroken.

The owl pellets that you will be examining in this lab have been collected and fumigated from common barn owls. Owl pellets themselves are ecosystems, providing food and shelter for communities which may include clothes moths, carpet beetles and fungi. Clothes moth larvae are frequently abundant in pellets, feeding on fur and feathers. The black spheres about the size of periods (.) that are found in the pellets are the droppings of the caterpillars. The larvae metamorphose near the surface of a pellet in cocoons made of fur.

Procedure

1.Measure the length and width of your owl pellets.

Length of your owl pellet_______

Width of your owl pellet_______

Mass of your owl pellet______

2. Carefully examine the exterior of the pellet. Do you see any signs of fur? _____ any signs of feathers? ____

3.Carefully use a toothpick to break apart the owl pellet and observe what is within. Use a toothpick to expose all bones for identification. Use the bone diagram to help you identify your bones and complete the chart.

4.Organize the bones into groups and label them, use the attached chart to help you identify bones.Construction paper will serve as a mounting surface. Grade will be based on neatness, labeling and organization.

Analysis

1. What do we know about the digestive system of an owl based upon the pellets?



2. Owl pellets not only can give us information about the diet of the owl, owl pellets also provide a habitat for other animals, in fact an owl pellet is a little ecosystem all on its own.Ý Why kind of animals are found in the ìowl pellet ecosystem (Hint: read the background at the beginning)



3. Other types of birds form pellets. What would you expect to find in the pellet of a seagull?



4. Owls, hawks, and eagles are types of raptors, animals which have hooked beaks and sharp claws, and are therefore adapted for seizing prey animals. Hawks and eagles differ from owls in that they eat their prey animals by tearing them into small pieces, picking out the flesh and avoiding most of the fur and bones. They also have strong stomachs which can digest most of the bone material which they might eat. The relatively small amount of indigestible bone and fur that remain will be compacted by their stomach muscles into a pellet similar to the owl's. Do you think an eagle pellet would be as useful for dissecting as an owlís? Why or why not?



5. Construct a diagram of a food web (of at least 5 animals) with an owl at the uppermost trophic level.Ý Use an arrow to show which organism in the consumer or predator.

Answer 5

check out amtrak.com they have a fare finder. there are 2 different stations in oakland and Vegas so you need to figure out wich station would be best for you, and just like planes the price veries in time and dates traveled.

Answer 6

better to drive.

Answer 7

train service ended a few years ago.

the closest station is Kingman Arizona, where you can either catch a bus or rent a car.

But it will probably be cheaper to fly, or go Greyhound the whole way.
