The Chimney Swifts may have
fledged out of our chimney today.
No sounds anyway. CHSW may
leave the nest and cling to the
"chimney" for a few days, per
lit. Then they fledge at about day 28.
Four or five pure white
eggs. Incubation by both parents for 19 days.
Just a pair of two is all that
is allowed when nesting in each chimney.
Then they congregate big time in
appropriate chimneys prior to
or during migration.
We probably inadvertently aided
them with chimneys the last
century. Now I notice new
home constructions have chimney
guards and screens, so, perhaps
we're not aiding them now in that respect.
