Early April warblers

Louisiana Waterthrush, Hadley Reservoir, Hadley, MA, Apr 7, 2021
Palm Warbler 'yellow', Rail trail, Amherst, MA, Apr 7, 2021
Palm Warbler 'yellow', Lake Wallace, Belchertown, MA, Apr 2, 2021

The first week of April has produced four species of warblers so far with a few early arriving Louisiana Waterthrushes today plus loads of Pine Warblers and the first arrivals of Palm Warblers and Yellow rumped Warblers since the beginning of the month.  The Pine Warblers have arrived in large numbers over the last couple days as migration conditions have slowly improved.  Overall the weather has been quite nice for early April with lots of sun, above normal temperatures (highs in the 60's for the last few days).  The winds have finally started changing from northerly to a more southerly flow.   There should be a noticeable increase in both Palm Warblers and Yellow rumped Warblers over the next several days (and always the chance of an overshoot rarity).
