Wren takes possession of Phoebees [Phoebe's]
nest in shed & fills it with sticks

(Troglodytes aedon) contemporaneous with the laying of a second
clutch of eggs yet on June 24 [June 24, 1912] the [female] in front of the house scolded
me vociferously when I approached her box closely, as if she had
young in it. About this same date her mate began haunting our
wood shed and behaving very oddly there. During the following
week he spent most of his time in it singing on the roof
and wood pile and exploring every nook & cranny of the latter.
Within the shed a Phoebee [Phoebe] had hatched his brood and taken
it away just before this. The Wren now took and for three
days held, possession of her nest within which he erected a
bristling down of dead twigs. Finally the Phoebee [Phoebe] returned
and threw out all the twigs which the wren replaced as soon
as the Phoebe was gone. This has gone on continuously now
for three days (June 26-29). The [male] Phoebe haunts & sings near
the shed only in the early morning. The [male] Wren is there
all day. I have seen the [female] Wren of this pair only on
or near her box.
