Disturbances to continuous forest such as roads or cleared patches of land often cause forest fragmentation. Resulting tracts of forest are often too small to support populations of top predators. As a result of this, mesopredators populations are left unchecked and increase to unnatural abundances. One consequence of this is increased predation on tropical bird nests, which may put them at risk for extinction. I constructed 120 artificial bird nests and placed two quail eggs in each nest. Nests were situated along 12 transect lines that ran into the forest, perpendicular to a road in Monteverde, Costa Rica. Predation was observed over a period of 27 days. Chi Squared Tests revealed that distance from the road had no effect on predation lev...
