1 March 2018 – no casualties


22, 24, 29, & 31 January 2018 – no casualties

Here’s a bit of a retrospective on the past year, though. I arbitrarily divide the calendar year into spring (Mar–Jul) and fall (Aug–Feb) monitoring. We’ve still got February to go, but my data aren’t likely to change much before the end of this next month.

The irony of having marked some windows in 2016 and seeing a new high count of dead birds in 2017 is not lost on me. I’m not sure what to think of that other than a standard admonition against drawing conclusions from just a year of data. Either way, 2017 was startling. My previous high count of 41 casualties occurred in 2010. The ensuing 5 years accrued fewer than 30; last year we were back up to 40. The 2010–2016 average was 37. Thus, the 61 casualties I found in 2017 was fairly shocking.
