Como Park Bluebird Trail Update: May 31, 2017

Post contributed by Sharon, volunteer bluebird trail monitor:

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.
