Barn Owl Relocation---Biology
Transcript of Barn Owl Relocation---Biology
Due Dec 14,2012 Barn Owl Relocation New Location: Factors: Abiotic Physical Description: Medium sized body, with long legs, which are sparsely feathered down to their grey toes.
The head is large and rounded without ears tuffs
Rounded wings & short tail covered with white or light brown down feathers
The head and the back are light brown with various black and white spots
The underside is a grayish white color
Females tend to be larger (570 grams)
Males (470 grams)
Females have a longer body (34-40 cm)
Males (32-38 cm)
Wingspan 107-110 cm Behavior of organism: Scientific Name: Tyto Alba Common Name: Barn Owl Reason for relocation:
The shopping center that is supposed to be built is right on top of the nest in which the barn owls live in. The construction of the buildings would cause harm to the owls. Nesting:
Most Barn Owls nest in high places – up to 20 meters high. However, Barn Owls are not really known for being good nest builders. In fact, they usually look around for existing nests. Once they find a suitable nest, they also re-use it year after year.
Typically short-tailed Vole, shrews, wood mice, young rats, & other rodents.
The Barn Owl does not have a specific breeding season. It mainly depends on the food supply. To attract the female, the male Barn Owl uses a special call. It also hovers in front of the female to show off its chest and belly. This is called the moth flight. During this process, both male and female fly around chasing each other all the while calling out to each other as well. Prey of organism: Scientific Names: Common Names: Meadow

Great Horneo Owls---Bubu wirginianus

Short eared owl(Asio flammeus)- Diagram of Food Web: The abiotic factors of the new location are the rain, snow, and temperature. The biotic factors of the new location are the food supply for the barn owls. We believe we should relocate the owls to a wooded area or farmland. Summary: We propose the relocation of the barn owls so that they are not endangered during the construction process. A wooded area would be the best because it would provide hollowed trees and lots of mice, shrew, and other rodents live in these areas. In this new habitat, they would be able to survive much better and live happily. Jessica: Date, Preparers(group members)
