|Pine Warbler with unusual markings, Quabbin Park, Apr 22, 2013|
As an update to warbler migration so far this season I will mention what has been seen so far and compare it to last year. During March last year I had three species of warbler but had none at all this March. So far this year, as of today, I have five species of warbler including Pine, Palm, Black and White and Yellow-rumped Warbler as well as Louisiana Waterthrush. On the same date last year I already had seven species. The warbler migration should pick up quite a bit over the next few weeks with dozens of species arriving.
