Nest predation

The effects of Nest predation with reference to open and vegetated environments

Abstract
The predation of nest in vegetated and open areas was studied in a broad area around the Illiwarra region from 13/3/03 to the 23/3/03. Experimental nests were used made from halved tennis balls and modeling plasticine was used to make eggs. The result of 36 nests were collaborated. Each nest had three eggs, the type of predator that attached the nest was recorded. 58% of the 36 nests were attacked with 57% of the nests attacked being in the open. The highest amount of predation came from other birds with 42% of the eggs attacked in the open and 33% in vegetation. Accounting for 40% of all nests attacked.
Our studies concluded that nests in the open are more likely to encounter predation than those in the thick vegetation.
