Warbler migration continues to slowly increase as more and more species join mixed species flocks and grow increasingly quiet with very little warbler song occurring as the third week of August comes to a close.  Some species have already largely vacated the area including Louisiana Waterthrushes and those at the northern limit of their breeding ranges.  I have been out as much as I can be but the mosquito population has exploded here and even with heavy amounts of bug spray it has been tough to bird.  I have had 21 warbler species so far for the month and hope to add a few more as migrants continue to trickle in from the north.
