The Hermit Thrush 103 
looking under the branches. In such cases, or when the Thrush is flushed from 
the nest, 1f she is merely incubating, she usually disappears quietly. When the 
young are in the nest, the bird acts more disturbed, often mounting a stump 
or branch, and calling chuck! chuck! chuck! or sometimes p-e-e-p! p-e-e-p! This 
almost always attracts the attention of her mate and the other Thrushes, who 
respond in numbers, and join their calls to the chorus of chucks and peeps. I 
have known the bird, however, to fly away almost without a protest, even when 
the young were taken from the nest. 
August 22, 1909, while gathering blueberries for the tame Thrushes, I flushed 
a Hermit Thrush from her nest, containing three eggs. This is the latest date 
on which I have found the Hermit Thrush nesting. 
August 27, three young were hatched; twelve days later, September 8, the 
nestlings left the nest before 9 o’clock. : 
The time of incubation, as one can readily see from the above record, is twelve 
days; the young remain in the nest twelve days, and leave early in the morning, 
as a general thing. One egg is laid each day about ten o’clock in the morning, 
and the bird begins to incubate by 12 o’clock of the day the clutch is completed. 
I have found the number of eggs in a set to vary from four to two. I should 
judge from the nesting dates I have gathered that the Hermit Thrush, like its 
cousin the Robin, raises from two to three broods during a season.
