Nestbox Summary for 2009

This year showed a slight decrease in MOBL fledging number. Possible factors included: 2008 -2009 winter was colder than usual on the west coast, and we experienced bear damage to about four boxes two which had bluebirds nesting in them. Another downside was that there was only one second nesting of bluebirds.

A disturbing trend was the continued decrease in Tree Swallow fledgings for the third year in a row. Many nest were found abandoned and some had dead young. This year we recorded approximately 174 eggs laid in 41 nests and only 91 young that fledged successfully.
