Now that we are midway between the second and third week of September the warbler migration thus far has been one of the worst falls I have ever seen as far as total numbers and diversity goes.  Even species that normally are around in small numbers have been totally absent for me (and reported by few others).  I have had 23 species so far for the month but have yet to find even a single Connecticut Warbler, Cape May Warbler, Bay breasted Warbler or Wilson's Warbler.  Other species I have seen just a handful of individuals despite a lot of effort outside.  I truly hope the big push has just not moved through but given the date a huge push seems somewhat unlikely.  The other possibility is that many of the large numbers and diversity have already moved through on good migration conditions and didn't stop in the area.  I'm still hopeful I will catch up with the above mentioned species at some point before September ends.
