[Maine-birds] Cutler warbs, Hermit TH & SASP 2nd broods

Hi Folks,
 
While working in Cutler last week I picked up a nice array of warblers in spite of the weather which suppressed bird song, a handicap when working in open barrens next to the woods.
 
In regards to frequent comments on hermit thrushes, They were singing and calling in the AM and late afternoon 4 to 7 per day.  They were also numerous in Machiasport.
 
Based on the combination of song activity and call note types and broods, they appear to have initiated a second brood.  Same for white throated and savannah sparrows.
 
Quick Ant Question?
 
Has anyone noticed medium sized black ants harvesting something from young upper shoots and upper-lateral native larch or tamarack branches on shrubs ranging in height from less than a foot up to six or seven feet.  If you grab the twigs to place surveyors flagging around them (the twigs, not the ants), your hand gets covered with ants that do not shake off easily (rain or shine).  This activity has picked up over the last two weeks.  I cannot recall if vireos were attracted to these trees.
 
Larches often attract migrating warblers and kinglets to their crowns just before leaf-out.  I used to have a number of larch trees (30-35 ft tall) in the University of Maine Forest on the Stillwater Avenue extension each year that I would visit almost daily.  Usually there were be up to twenty-plus birds comprising more than ten species on the tree while birds were hard to locate elsewhere. This sometimes lasted for two weeks.
 
Here in Augusta, I have a tall larch tree about 75 feet into the woods off our back deck that attracts many early migrants plus larger numbers of migrants during peak migration.  I have picked up many relative early records for some of the more hard-core insectivores.  I have no idea what they are chowing down on.
