Checklist Comments

After what has been a slow and underwhelming spring migration the big push of warblers/migrants finally came through (sort of a day after it was originally thought). Overnight conditions consisted of heavy rain and strong SSW winds (severe t-storm and tornado watch in western/central MA with hail potential) that moved eastward across the state starting pre-dusk in the Berkshires and continuing with only occasional breaks in the rain until almost 5am or so coastally. I personally didn’t have high hopes with the heavy rain starting pre-dusk, (and so unfortunately didn’t make the extra effort to arrive predawn) but radar seemed to show some movement amongst/between the rain bands as the night progressed though it was hard to tell with the Boston/Taunton radar station down for maintenance. Morning conditions were nearly perfect with a light fog lifting at daybreak and a nice dull complete cloud cover that made spotting birds in flight much easier until about 8ish when it dissipated into blue skies. Mostly calm with a light NW wind forming as the morning progressed; 58-70°f. Morning flight was already in full force when we arrived a bit after 6:30 and many hundreds (thousands?) of birds were likely missed because of this. We quickly positioned ourselves by the NPS house at the top of the bluff which seemed to be the best vantage of the both the overhead morning flight and the surge of migrants passing through the thickets when we arrived. During the first hour to hour and a half it was a constant flight of warblers overhead and in the bushes so most of our focus was close by. As things started to slow down after about 7:30, we started scanning the sky west of the bluff and noticed the flight was stronger to the west of us at this point (though this also could’ve been due to a higher detection rate given conditions). Visibility to the east of our vantage point was almost nonexistent, so I have no idea if there was a similar movement over the east marsh/dunes (though I would suspect that it was reduced to a certain extent). If the flight to the west of us was happening the entire morning (and I have no real reason to doubt it was) then we missed many hundreds of individuals during peak flight. All birds were flying in a NNW direction or more or less following the contours of the land and most were pretty low (despite the lack of a head wind) with some birds in the flight to the west of us moving at or below eye level. The flight had basically stopped but for a few stragglers by 8:30am and activity in the thickets was also dramatically reduced by 9. Note that none of these counts are exact but rather represent somewhat careful conservative estimates of birds that we could detect and identify. Would’ve been helpful to have more eyes! Thanks to Marshall Iliff for the heads up that this weather system had the potential to produce a heavy coastal movement. An impressive flight despite the lack of a concentrating or funneling feature, and the flight a bit later in Ptown shows that we really did miss thousands of birds. It would have been fun to see the flight on radar, but couldn't with the station down. Being positioned on the north end of the bluff may have yielded a better or at least wider view of the morning flight but would not have allowed for the observation of the movement through the thickets. After the flight ended we walked the first half mile of the bike trail (and missed the continuing marsh birds) before heading into Ptown to see if any of the warblers had put down out there (some had, with most trees having birds, but clearly some birds had continued migration across the bay). Photos to be added.

Gray warbler with bright yellow cap and broad wing patch; whitish supercilium and malar contrasting with black auriculars and throat. Semi-extensive white in outer rects. Never heard to vocalize, but it might have called once and I missed it.
