Abstract

Seventeen birds from 12 flocks were exposed to microwave radiation under various combinations of power density and duration; three birds from two additional flocks served as sham-exposed controls. Experiments were conducted outdoors at Manomet, Massachusetts (41 degrees 56'N, 70 degrees 35'W) under normal winter ambient temperatures. Although irradiated birds maintained their positions within a flock hierarchy with one exception, some appeared to have a change in their level of aggression after exposure.

Main findings

Irradiated birds generally maintained their positions within the flock hierarchy (with one exception). Some irradiated birds appeared to have a change in their level of aggression after exposure.

Outcomes measured

dominance behavior
flock hierarchy position
aggression level

Limitations

Exposure parameters (e.g., frequency, specific power densities, and durations) not reported in the abstract
Small sham-exposed control group (3 birds)
Outcome changes described as "appeared" (suggesting subjective/uncertain assessment)
