Common Nighthawk (Chordeiles minor) Science Article 3
abstract
Both Slessers (Auk 87:91-99, 1970) and Simmons (pp. 101-104 in A Dictionary of Birds, B. Campbell and E. Lack, eds., Buteo Books, Vermillion, South Dakota, 1985) classified methods of bathing in water by birds, but neither mentioned a method we observed in the Common Nighthawk (Chordeifes minor), and here named ‘aerial rain bathing.’
