Como Park Bluebird Trail Update: April 23rd

Post contributed by Sharon, volunteer bluebird trail monitor:

Standard bluebird eggs
Unusual white bluebird eggs

The first eggs have been laid. The cherry trees are in bloom. A female bluebird flew out of one box as I approached and I found five blue eggs inside. Another box contained four white bluebird eggs. White bluebird eggs are less common, and may be a genetic trait associated with the female. This is not the first time white eggs have been laid on the Como Park trail.

Four more boxes contain completed bluebird nests. At one, I found a damaged pale blue egg on the ground. The nest inside was empty.

So far, no chickadees or tree swallows have moved in and five boxes remain empty.
