Abstract
Observations of blackbird and starling reactions to helicopter flyovers were made at 12 winter roosts. Extensive bird flushing was observed during 6 flights that were conducted on clear (cloudless) nights. No appreciable bird movement took place during the 6 flights on overcast nights. Helicopter type, time of flight, roost habitat type, bird species composition, and external lighting appeared to have little influence on the amount of flushing observed. The data suggest that the best conditions to apply an avian toxicant by helicopter would be on an overcast night while flying at the highest permissible elevation.
