Fall 2016 Week 5 Update

This week saw a large jump in bird strikes (table 1.) from 16 last week to 39 this week, our largest amount this season.  Starting last Monday and Tuesday we saw large numbers taper off as hurricane Matthew made its way up the coast.  As hurricane Matthew decreased in intensity bird strikes began rising once again on Sunday (table 2.).  This follows closely to what was predicted by the Cornell Lab of Ornithology BirdCast from last week. Interestingly 18 of the 39 birds found this week were from one route (table 3.).  Normally this route has regular window strikes but this week in particular saw a larger than normal proportion of birds striking windows.  Last week one of our more interesting stats was the 50/50 ratio of dead to live birds which is very uncommon.  This week we again saw a near tie of 22 dead to 17 live birds (table 4.).

This week we should see moderate to heavy flights as the week begins with favorable conditions wide spread across the region.  as the week progresses, remnants of hurricane Matthew will begin to pass through the Great Lakes region meaning potential changes in migration paths.  As hurricane Matthew moves out to sea a disturbance moving east should bring moderate to heavy flights across the region.  Make sure to keep watch on what hurricane Matthew does through the week as any changes to the storm could have impacts on us inland.
