I was really hopeful that one of the last few days would bring a huge increase in warblers given what appeared to be great migration conditions following multiple days of less than ideal conditions.  I really thought one of the days would give me a big warbler day where I can usually get a total in the upper 20's in Hampshire County.  Unfortunately none of the days produced warblers in the diversity or numbers I hoped for with my highest total being 20 species yesterday.  I'm not quite sure why none of the days produced as expected but at least there were still birds to be seen and heard.  This morning was probably the least productive yet despite what seemed to be good migration conditions overnight.  Sometimes birds just do not cooperate as one hopes for.  As of today I still have not had a Tennessee Warbler or Blackpoll Warbler for the year (nor any rarities) so my hope is that there is still a bunch of warblers still on their way north.  Time will certainly tell and I will be out tracking them down and keeping my fingers crossed.  As of mid month I have had 26 species with a few of those represented by just a single individual.

I also tracked down all the Blue winged Warblers I heard over the last several days and the reward was a hybrid that sang a typical Blue winged Warbler song but had yellowish wing bars and a hint of a mask with a comma shape at the end of the typical Blue winged eye line.  I have seen this facial marking a few other times with backcrosses with examples in Southampton last year and another in Amherst along the rail trail that turned up for two years.  The Brewster's Warbler also continues in Amherst.  I'll do a more in depth post once again on these various hybrids in the future once migration has come to an end.

The camera at the water feature captured a few more warbler shots the last several days but nothing unusual yet.
