Hi all,
This is our first year to have bluebirds nest in a visible way (nest box) on
our property. Generally we see them in the spring and then they disappear
for the rest of the year. I have helped them along with many, many mealworms
at first to talk them into staying but then because it was so cold for so
long. While it was rewarding and I'll admit fun, I don't know if the
mealworms are really in the best interests of the bluebirds in a long term
sort of way.
Their first effort yielded five eggs with four that fledged on May 21.
Second nest, after a territory battle with a pair of persistent wrens,
yielded five eggs with five fledged on July 10. So that's about 7 weeks
between fledgings (is that a word?).
I noticed today that our pair has a third nest well under way but no eggs
yet. This seems a bit late compared to what others are reporting. If they
went another 7 weeks to fledge a third nest that would take them to the end
of August or the first week of September. Do they ever fledge that late?
Will the young get enough of a start to survive the winter?
And apart from the bluebirds, we've had two batches of Eastern Phoebes
fledge. The persistent wrens have now settled into a second Bluebird box my
husband hastily built during the territory wars of late May.

Hi Brian & Becky:
Congratulations on your Triple Brood Nest--good luck with its development.
Triple nests develop only under the most ideal of conditions and according
to the 8 year records of the Audubon Society in central WI (Aldo Leopold
Chapter), are built only in July (usually during the1st three weeks).
Currently, our bluebird trail of 1,066 boxes has only one Triple Brood Nest
on it (4 E's).
As a whole, this has been a better nesting season for bluebirds on our trail
than last season and that seems to be reflecting the general trend
statewide--our sub-trails at Ft. McCoy are having an unbelievable year and
are currently averaging the potential to fledge 7.5 EABL's/nest box (151
nest boxes), perhaps the best performance for a single geographical site in
the 23 year history of the Bluebird Restoration Association of WI (BRAW).
Our trail should fledge 5,000-5,500 bluebirds for the season plus another
1,000 of the "big three".
I hope you have a chance to send in your fledging records to me at the end
of the season. Contact me for details.
As an aside, I experienced last week a first for the Audubon Trail. A
single bluebird nest with 9 E's--a recent thread
asked about maximum number of E's for a Purple Martin and "egg dumping" was
brought up. I am sure this 9-egg
nest is an example of egg dumping. My personal records for a single nest
for the common cavity nesting songbirds are: Black-capped Chickadee (14 E's,
6 hatched and fledged); Tree Swallow (10 E's/6 hatched and fledged; my wife
owns the state record for TRES's, having had 9 of 9 hatch and fledge) and
House Wren (9 E's/9 hatched and fledged). So these species can be quite
prolific under the right circumstances.
