Golf Course Transition Logs

Problem 1-holers to HOSP-Free 2-holers 

This was a standard 1-holed box trail acquired from another monitor in 2001.  When House Sparrows caused problems, the previous monitor either relocated the standard 1-holed boxes or removed them.  It was my original intent to keep 1-holers in place.  However, there were Bluebird losses in the 1-holers caused by HOSP and it was transitioned to 2-holed boxes.  During this timeframe, the Keys to Success  had not been fine-tuned and the transition from problem 1-holers to defensible 2-holers was more difficult.  Historical 1-holed notes are included so monitors can compare 1-holed to 2-holed performance during a transition (even w/o all the Keys being known at the time).


Color-coded yearly summaries are at the top of each problem site so readers can find problems (red color).  Weekly log notes follow the summaries for monitors who would like to see more details of what to expect during a transition from problem 1-holed boxes through the first few nesting seasons as Bluebirds learn that they can outcompete House Sparrows. 


Slanted Tree (Fairway #1 1st House) 

Box location changes:  On 6/5/02, an alternate box was hung nearby to coax Bluebirds to the edge of golf course.  The second box attracted a second pair of Bluebirds.
