Sampling Tree Swallow Eggs and Nestlings TVA-KIF-SOP-28

March 2010


2 meters from any structure (tree branch) that a predator could jump from onto the box. Nest boxes are installed in early April. The latitude and longitude of each nest box is documented during or immediately following the sampling event using a hand-held GPS unit. Mounting poles are equipped with predator guards.

Nest boxes are surveyed for occupancy over the course of the breeding season, including after installation, and then at appropriate intervals depending on activity in the nest box. During surveys, boxes are evaluated for presence/absence of adults, nesting material, egg clutch size, nestlings, and egg/nestling survival rates.
