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. 

A few early arrivals and late species for the first third of August

Summer continues to rapidly march on and we have now made it to to the first third of August.  I have been out most everyday and have had a few early arrivals including a Bay breasted Warbler on the 6th, a Tennessee Warbler yesterday and at least two Louisiana Waterthrushes today.  I now have had a total of 20 species for the month in Hampshire County and will certainly be looking to add to that total as August continues on.

I have been out the last few mornings to start adding warblers to my August list.  On the first I had some good stuff including a slightly late Cerulean Warbler plus a Worm eating Warbler in the same mixed flock as well as others netting me a lucky 13 species to start off the month.  The second got me three more species as I covered a variety of habitats.  Monday was basically a rain out with little chance to get outside.  The last couple mornings have been much nicer with coolish mornings and sun throughout the morning with no new species added so a total of 16 species of warblers so far for the month.
