Como Park Bluebird Trail update: May 25th

Post contributed by Sharon, volunteer Bluebird Trail monitor:

Four tree swallow eggs

Three bluebird eggs

The four boxes occupied by bluebirds contain a total of seventeen eggs today.  Chickadees are in two boxes and have laid at least five eggs.  When I opened one box, an egg was so near the edge of the nest it almost toppled out.  Tree swallows have taken two boxes; one has four white eggs in it. Two boxes have small amounts of nesting material inside.  A house wren was singing by the last box, and had put a few sticks inside.  Wrens will put sticks into several nest options and the female will choose which one she likes best, then build a nest in it.
