Ten more bluebirds fledged in August. The season is now over and all the boxes have been removed for cleaning and winter storage. A total of 53 birds fledged from the trail this year: 33 bluebirds, 11 chickadees, and 9 tree swallows.

Como Park Bluebird Trail Update: July 27, 2017
Post contributed by Sharon, volunteer bluebird trail monitor:
In the past two weeks, 4 bluebirds and 7 tree swallows fledged. Eight nest boxes are now empty as the
nesting season winds down. There are 12 bluebirds in the
remaining three occupied boxes, 8 likely to fledge soon. Vandalism is
unfortunately a recurring problem on the trail—two weeks ago a pinecone put
into a box prevented bluebirds from laying eggs. Those bluebirds moved to
another box, built another nest, and laid 5 eggs, only to have another pinecone
put into their box—this time two eggs were destroyed, the rest could not be
incubated, and the pair gave up for the season. A predator guard in the same
area of the trail was also broken.

A tree swallow nest with at least four week-old chicks in it failed—the chicks were dead and covered with flies. It may be that this pair of tree swallows began another nest right away on top of an old bluebird nest in another nearby box—the new tree swallow nest has four eggs in it. Another two boxes have at least 5 tree swallows at various stages of development.

There are 6 healthy chickadees approaching two weeks old in another box. Two weeks ago mom was on that nest, and a week ago, she was also on the nest along with her nearly week-old chicks! Next time I checked, the 6 youngsters had feathered out and filled up the nest and mom would have been hard put to find room to fit on the nest with them.

Fourteen birds fledged in the past week—nine bluebirds and
five chickadees. There are ten more bluebirds ready to fledge in the next week
or so, and three new bluebird eggs laid. Two boxes have at least six young tree
swallows in them, and one more box has tree swallows in it, but mom was sitting
on the nest and didn’t allow any observations. A chickadee mom is also hunkered
down on her nest, staying put no matter what—she probably learned this was
necessary when fending off the encroachments of persistent tree swallows two
weeks ago. If she’s still on the nest next week, though, it could mean her eggs
are not viable and won’t hatch.

Recently hatched bluebirds. |
The cool weather in the past two weeks hasn’t stopped the
bluebirds, chickadees, and tree swallows from progressing with their nesting
activities at Como Park .
Four nest boxes contain 19 bluebirds—9 over a week old and 10 more recently
hatched. Two boxes have chickadees inside—one has 5 over-a-week-old chickadees
and the other has eggs. The chickadees with eggs in their nest are being
challenged by a pair of tree swallows who sit on top of the box and claim it as
their own. I installed a smaller 1-1/4” entrance hole guard so only the
chickadees could enter the box, and maybe that will encourage those tree
swallows to look elsewhere for a box of their own. Two nest boxes have at least
8 tree swallow eggs inside, and three nest boxes contain partial nests that may
have been abandoned.

Nesting
season is well underway this week—things can happen fast once they get going.
Now there are 20 bluebird eggs in four nest boxes, six chickadee eggs in one
box, and four tree swallow nests built. Two other boxes have some nesting
materials inside but not enough to identify the creators.
Bluebirds usually lay between 3-5 blue eggs,but for the last few years we've had a pair that lays 6 or 7 pale white eggs. |
Chickadee eggs are smaller and speckled. |
