BCCH = Black-capped Chickadee
EABL = Eastern Bluebird
FS = Flying Squirrel HOSP = House Sparrow
NABS = NABs style nestbox
PETE = Peterson style nestbox
SLOT = Slot style entrance on nestbox
TRES = Tree Swallow
Hanging boxes are about 100 yards apart. I am counting a nest as an attempt - especially because I am removing HOSP nests. Some monitors only count an attempt when an egg has been laid.
Boxes with numbers followed by an "x" are not part of this experimental trail, but I try to keep an eye on them. They are single-holers, pole mounted, with the entrance about 5 feet off the ground.
In the 2006 nesting season (before I started monitoring the trail) it appears from nests left in boxes that all seven single-holed boxes were used by HOSP, although one or two may have been Tree Swallow nests.
In 2007, 2 bluebirds fledged from H-12, and one box (H-8) was eventually occupied by a flying squirrel. H-9 was apparently stolen.
In 2008, H-10 was moved to a location about 1/2 mile down the road. H-9 and H-11 are occupied by flying squirrels. I am excited to have them using the boxes, and interested in observing them. For those who do not want Flying Squirrels in their boxes (if the goal is to fledge more native birds, or they are concerned about Flying Squirrels eating eggs and young), try placing boxes away from mature forests and/or lowering height. I am looking at making changes so there is only one 2-holed box in the middle of a 2-acre forage territory at
least 300 feet from any other nestbox.
In 2009, a box went missing. We installed a two-holed pole mounted box underneath H-11 to see if there was any interest. It has a very large overhanging roof.

APPROXIMATE SHORTEST distances between boxes:
H-9 is >300 feet away from H-10 and H-11).
H11 to H12: 230 feet
H11 to H10: 260 feet?
H10 to H9: 350 feet
H9 to H12: 220 feet
6x to H10: 100 feet (Note: H-10 moved to another location in fall of 2007)
6x to H9: 250 feet
Note: the recommended distance between boxes for bluebirds is 300 feet, but these boxes were spaced more closely in 2007 because of limitations in tree locations, size of the town green, and the hope of attracting other native cavity nesters.
NOTE: THE LOG BELOW and drawing SHOW USE OF THE TRAIL BEFORE AND AFTER TWO-HOLE HANGING MANSIONS WERE INSTALLED
