There is always a difference in year to year migrations, and this fall has been noticeably different than last year. I am guessing that fall 2016 may be the high bar for what I should expect in terms of warbler numbers and variety on a day to day basis in August and early September. Fall 2017 has been more inconsistent than last fall with warbler numbers through September 4 generally lower. Since I posted my warbler totals through September 4 last year, I thought it would be interesting to compare numbers through the same date. There have been falls in the past that have been inconsistent like this year, so it's not completely unique. The first main thrust of warbler into the area this fall did begin several days later than last year in line with some of the past inconsistent falls.
