Reports on Nestbox Maintenance

The Tree Swallow nesting box program has gathered considerable success since its inception in 2004.

In 2012, 15 boxes were occupied – 2 Swallow, 9 Sparrow, 2 Chickadee, 2 double (Swallow/Sparrow).

In 2013, 6 boxes were occupied – 2 Swallow, 3 Sparrow, 1 Chickadee, 25 empty.  (So many were empty because baffles had been put on most to reduce the opening size so that Sparrows could not fit.  Swallows must have had trouble too.  Most of these were removed for the next year.)

In 2014, 16 boxes were occupied – 4 Swallow, 11 Sparrow, 1 double (Chickadee/Sparrow), 15 empty.

In 2015, 20 boxes were occupied – 8 Swallow, 9 Sparrow, 3 Chickadee, 11 empty.

In 2016, 23 boxes were occupied – 9 Swallow, 10 Sparrow, 2 Chickadee, 2 double (Swallow/Sparrow), 6 empty.

In May 2017 there are 17 boxes that have been occupied by Tree Swallows.  The average number of eggs is 5.  Some will not hatch, but expectations are the boxes will produce in excess of 70 new Tree Swallows.
