Impatient House Wrens have been seen here as early as March 15th
(1903) and several times between the 1st and 10th of April.
During some years they arrive between the 15th and 21st of
April, the bulk of the migrants passing between the 5th and 8th
of May, at which time they swarm in the willows of the Missouri
bottoms. They leave during early September and are rarely
seen after the middle of the month.
This wren nests in birdhouses, in crevices about buildings, in
the pockets of discarded garments, in tin cans and in other
similar situations too numerous to list. It also nests in
the deep woods of the bottom lands and other wild places in
natural cavities in trees and deserted woodpecker holes.
Five to seven eggs are laid in May.
