The Monroe Wagner Vaux's Swift roost security camera was functional all July. Here are the July totals for the last nine years. Next we show how many nights we didn't get an observation because the camera wasn't working, and then what the months total might have been by adding the number of missing nights x that years nightly average.

year total swifts Missing nights Might have been
2011 5,062 4 5,810
2012 10,550 11 16,352
2013 984 1 1,017
2014 5,625 0 5,625
2015 2,508 8 3,380
2016 5,101 1 5,271
2017 3,230 0 2,320
2018 2,301 6 2,853
2019 8,265 0 8,265

So it was a great July for number of swifts using the Wagner roost.

But is that a good thing?

There is more to tell.
